El reposicionamiento malar. Presentación de una técnica original: punto MM / Malar repositioning. Presentation of an original technique: point MM

El envejecimiento facial es una sinergia compleja de cambios texturales de la piel, hiper- o hipoactividad muscular, reabsorción del tejido graso y resorción ósea. El déficit de volumen resultante, la deflación y la posterior caída del tercio medio facial produce una cara menos atractiva y juvenil. Los procedimientos inyectables en región malar son cada vez más populares y solicitados por los pacientes. El conocimiento de la anatomía de la cara media es fundamental para el inyector. La comprensión de la irrigación facial puede ayudar a disminuir la exposición a la aparición de hematomas y complicaciones vasculares severas. Existen múltiples técnicas de inyección propuestas para el tercio medio, en este artículo presentamos una técnica original, simple, segura y eficaz con resultados satisfactorios y riesgo reducido

Facial aging is a complex synergy of textural skin changes, muscle hyperactivity, fat dysmorphism, bone resorption. The resulting volume deficit and deflation of the mid face produces a less attractive and youthful face. Injectable midface procedures are becoming increasingly popular and requested by patients. Knowledge of the anatomy of the midface is critical for the injector. Understanding the irrigation of the face can help decrease the risk of hematoma and severe vascular complications. There are multiple injection techniques proposed for the middle third, in this article we present a simple, safe and effective technique with satisfactory results and lower risk

Da superfície para a profundidade: Curva de aprendizado em lifting facial profundo estendido - meus primeiros 100 casos / From Surface to Depth: Learning Curve in Extended Deep Facelift ­ my First 100 Cases

Introdução: O envelhecimento facial é um processo gradual, complexo e multifatorial. É o resultado de mudanças na qualidade, volume e posicionamento dos tecidos. Cirurgiões plásticos têm modificado sua abordagem na cirurgia do rejuvenescimento facial optando pelo plano subaponeurótico (SMAS). O objetivo deste estudo é analisar 100 casos de pacientes operados pela técnica de SMAS profundo, avaliando sua aplicabilidade e eficácia. Método: Foram avaliados 100 pacientes, submetidos a cirurgia plástica facial pela técnica de SMAS profundo - "Deep Smas", e acompanhados por 6 meses. Observou-se a satisfação dos pacientes, número de complicações, número de reoperações, riscos e vantagens da técnica. Resultados: Foram operados 100 pacientes, num período de 3 anos. A idade variou de 41 a 79 anos, sendo 95% sexo feminino. As complicações foram 8 casos (8%) de lesões de ramos do nervo facial, sendo: 4 casos lesão do zigomático, 3 casos de lesão do mandibular e 1 caso de lesão do bucal; houve 1 caso (1%) de queloide retroauricular; 1 caso (1%) de hematoma. Em relação às revisões cirúrgicas, houve 8 casos (8%) de complementação cirúrgica por insatisfação das pacientes. Houve 15% de lesões nervosas entre a 1ª e a 40ª cirurgia, 5% entre a 41ª e a 80ª, e nenhuma lesão entre o 81º e o 100º paciente. Conclusão: O lifting facial profundo ou subSMAS mostrou ser efetivo, proporcionando bons resultados estéticos. Apresenta baixa taxa de recidiva e baixa taxa de morbidade, porém, necessita de uma longa curva de aprendizagem.

Introduction: Facial aging is a gradual, complex, and multifactorial process. It is the result of changes in the quality, volume, and positioning of tissues. Plastic surgeons have modified their approach to facial rejuvenation surgery, opting for the subaponeurotic plane (SMAS). The objective of this study is to analyze 100 cases of patients operated on using the deep SMAS technique, evaluating its applicability and effectiveness. Method: 100 patients were evaluated, undergoing facial plastic surgery using the deep SMAS technique - "Deep Smas", and followed up for 6 months. Patient satisfaction, number of complications, number of reoperations, risks, and advantages of the technique were observed. Results: 100 patients were operated on over 3 years. Age ranged from 41 to 79 years, with 95% being female. The complications were 8 cases (8%) of injuries to branches of the facial nerve, of which 4 cases of zygomatic injury, 3 cases of mandibular injury, and 1 case of buccal injury; there was 1 case (1%) of post-auricular keloid; 1 case (1%) of hematoma. Regarding surgical revisions, there were 8 cases (8%) of surgical completion due to patient dissatisfaction. There were 15% of nerve injuries between the 1st and 40th surgery, 5% between the 41st and 80th, and no injuries between the 81st and 100th patient. Conclusion: Deep facial lifting or subSMAS has proven to be effective, providing good aesthetic results. It has a low recurrence rate and low morbidity rate; however, it requires a long learning curve.

Estereótipos raciais e atratividade física facial: explorando suas implicações nas avaliações morais em saúde / Racial stereotypes and facial physical attractiveness: exploring their implications in moral assessments in healthcare

Resumo Neste estudo com 333 participantes, investigamos como estereótipos raciais e atratividade facial impactam as avaliações morais na área de saúde. Utilizamos imagens de rostos com diferentes níveis de atratividade em cenários de dilemas morais, realizando análises estatísticas, como ANOVA e ANCOVA, para examinar essas interações complexas. Descobrimos que a atratividade física influencia positivamente as avaliações morais apenas em cenários de baixo conflito moral, não se aplicando a situações de alto conflito ou impessoais. A relação entre a cor da pele autodeclarada e o sexo dos participantes só se confirmou em um cenário específico, destacando a complexidade dessas influências. As hipóteses três e quatro, que sugeriam que as identidades racial e moral dos participantes suprimiriam os efeitos dos estereótipos raciais e da atratividade facial, não foram confirmadas. Entretanto, observou-se que o perfil étnico dos rostos, junto com a motivação dos participantes para controlar preconceitos, influenciou positivamente as avaliações morais. Esses resultados são interpretados à luz de teorias sobre atração interpessoal, julgamento moral e relações intergrupais, fornecendo insights importantes para as complexas dinâmicas que moldam as avaliações morais na área da saúde.

Abstract In this study of 333 participants, we investigated how racial stereotypes and facial attractiveness impact moral evaluations in healthcare. We used pictures of faces with different levels of attractiveness in moral dilemma scenarios, performing statistical analyses such as ANOVA and ANCOVA to examine these complex interactions. We found that physical attractiveness positively influences moral evaluations only in low moral conflict scenarios and does not apply to high conflict or impersonal situations. The relationship between self-declared skin color and participants' gender was only confirmed in a specific scenario, highlighting the complexity of these influences. Hypotheses three and four, which suggested that participants' ethnic and moral identity would suppress the effects of racial stereotypes and facial attractiveness, were not confirmed. However, we observed that the ethnic profile of the faces and the participants' motivation to control prejudice positively influenced moral evaluations. These results are interpreted in light of theories on interpersonal attraction, moral judgment, and intergroup relationships, providing essential insights into the complex dynamics that shape moral evaluations in healthcare.

Pediatricians' focus of sight at pain assessment during a neonatal heel puncture / Foco do olhar do pediatra na avaliação da dor neonatal durante uma punção de calcanhar

ABSTRACT Objective: To evaluate the focus of pediatricians' gaze during the heel prick of neonates. Methods: Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians' pain perception: absent/mild (score: 0-5) and moderate/intense (score: 6-10). Results: 24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5-8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain. Conclusions: At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face.

RESUMO Objetivo: Avaliar o foco do olhar do pediatra durante a punção do calcanhar de neonatos. Métodos: Estudo prospectivo no qual pediatras, utilizando óculos de rastreamento visual, avaliaram a dor neonatal antes/depois de uma punção de calcanhar. Os pediatras pontuaram a dor de acordo com a sua percepção por meio de uma escala analógica verbal (0=sem dor; 10=dor máxima). Os desfechos analisados foram o número e o tempo das fixações visuais na face superior, face inferior e mãos, em dois períodos de 10 segundos, antes (PRÉ) e depois da punção (PÓS). Os resultados foram comparados entre os períodos e segundo a percepção da dor do pediatra: ausente/leve (escore: 0-5) e moderada/grave (escore: 6-10). Resultados: Vinte e quatro pediatras (31 anos, 92% sexo feminino) avaliaram 24 neonatos. A mediana do escore atribuído à dor do recém-nascido durante a punção do calcanhar foi 7,0 (intervalo interquartil: 5-8). Comparado ao período PRÉ, no período PÓS, o maior número de pediatras fixou o olhar na face inferior (63 vs. 92%; p=0,036) e o número de fixações visuais foi maior na face inferior (2,0 vs. 5,0; p=0,018). Não houve diferença no número e no tempo das fixações visuais de acordo com a intensidade da dor. Conclusões: À beira do leito, os pediatras mudam seu foco de atenção visual na face do recém-nascido após um procedimento doloroso, focando o olhar principalmente na parte inferior da face.

Subtypes of temporomandibular disorders in patients diagnosed with otalgia: observational study / Subtipos de desordem temporomandibular em pacientes diagnosticados com otalgia: estudo observacional

ABSTRACT BACKGROUND AND OBJECTIVES: Temporomandibular disorder (TMD) has complex symptoms that involve the orofacial region, such as otalgia. Considering the difficult differential diagnoses for associating otological symptoms with TMD. The aim of this study was to verify the diagnosis of TMD in patients with otalgia. METHODS: This is a cross-sectional and descriptive study, where 75 patients diagnosed with otalgia were evaluated. The European Academy of Craniomandibular Disorders's (EACD) screening questionnaire was initially applied, and those who answered affirmatively to at least one question were evaluated by the Research Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), with a final sample of 50 patients. Data were tabulated and ANOVA verified whether there was a statistical difference between TMD subtypes classified by DC/TMD, considering confidence intervals with 95% significance. RESULTS: The mean age of the participants was 39.9±14.1 years, with a predominance of females (76%) (p<0.0001). Among those diagnosed with TMD, females also predominated, with a higher percentage in all evaluated subtypes, with emphasis on arthralgia (82%) and myofascial pain with limited opening (81.8%), followed by myofascial pain (74%) and disc displacement with reduction (72.7%). When observing the distribution of TMD subtypes between genders, there was a predominance of myofascial pain in males (75%) and females (68%), but no statistical significance was observed in this variable and in the others studied. CONCLUSION: Patients with otalgia had one or more TMD subtypes, and the myofascial subtype TMD was the most prevalent among study participants.

Quando observada a distribuição dos subtipos de DTM entre os sexos, notou-se predominância de dor miofascial no sexo masculino (75%) e feminino (68%), mas não foi observada significância estatística nessa variável e nas demais estudadas. CONCLUSÃO: Os pacientes com otalgia manifestaram mais de um dos subtipos de DTM, sendo o subtipo de dor miofascial o mais prevalente entre os participantes do estudo.

Evaluation of facial pleasantness in patients with complete and unilateral cleft lip and palate rehabilitated and submitted to orofacial harmonization

ABSTRACT Objective: The objective of the present prospective case control study was to evaluate the facial pleasantness of patients with complete and unilateral cleft lip and palate at the end of interdisciplinary rehabilitation, submitted to facial fillers based on hyaluronic acid. Methods: The study group consisted of 18 individuals with complete unilateral cleft lip and palate, aged between 18 and 40 years (mean age 29 years) of both sexes. The patients presented a concave profile with mild to moderate maxillary deficiency, with completed orthodontic treatment and conducted by means of dentoalveolar compensations without orthognathic surgery. Participants underwent facial filling procedures with hyaluronic acid (HA) in the midface, inserted by a single operator. Standard photographs in frontal norm at rest, right profile at rest, and left profile at rest were obtained from each patient at the following operative times: (T1) pre-filler and (T2) and one-month post-filler. The photographs in T1 and T2 were randomly placed on a page of a virtual album. A 5-point Likert scale was used to assess facial pleasantness. The photographs were evaluated by two groups of evaluators consisting of 18 individuals with cleft lip and palate (CLPG=18) and 18 orthodontists with experience in the treatment of clefts (OG=18). For comparison between phases T1 and T2, and between evaluators with orofacial clefts and orthodontists, the Wilcoxon test was used (p<0,05). Results: People with cleft lip and palate rated their face as more pleasant after the midface filling procedure. In the perception of the orthodontists, on the other hand, the facial pleasantness remained similar after the facial filling procedure. Conclusions: The filling of the middle third of the face in patients with cleft lip and palate treated without orthognathic surgery increased the pleasantness of the face in the opinion of laypeople with cleft lip and palate.

RESUMO Objetivo: O objetivo do presente estudo caso-controle prospectivo foi avaliar a agradabilidade facial de pacientes com fissura labiopalatina completa e unilateral ao final da reabilitação interdisciplinar, submetidos a preenchimentos faciais à base de ácido hialurônico. Métodos: O grupo de estudo foi composto por 18 indivíduos com fissura labiopalatina unilateral completa, com idade entre 18 e 40 anos (média de 29 anos), de ambos os sexos. Os pacientes apresentavam perfil côncavo com deficiência maxilar leve a moderada, com tratamento ortodôntico concluído e realizado por meio de compensações dentoalveolares sem cirurgia ortognática. Os participantes foram submetidos a procedimentos de preenchimento facial com ácido hialurônico (AH) no terço médio da face, implantado por um único operador. Fotografias padrão em norma frontal em repouso, perfil direito em repouso e perfil esquerdo em repouso foram obtidas de cada paciente nos seguintes tempos operatórios: (T1) pré-preenchimento e (T2) um mês pós-preenchimento. As fotografias em T1 e T2 foram inseridas aleatoriamente em uma página de um álbum virtual. Uma escala Likert de 5 pontos foi utilizada para avaliar a agradabilidade facial. As fotografias foram avaliadas por dois grupos de avaliadores formados por 18 indivíduos com fissura labiopalatina (GFLP=18) e 18 ortodontistas com experiência no tratamento de fissuras (GO=18). Para comparação entre as fases T1 e T2, e entre avaliadores com fissura labiopalatina e ortodontistas, foi utilizado o teste de Wilcoxon (p<0,05). Resultados: As pessoas com fissura labiopalatina avaliaram seu rosto como mais agradável após o preenchimento do terço médio da face. Já na percepção do ortodontista, a agradabilidade facial permaneceu semelhante após o procedimento de preenchimento facial. Conclusões: O preenchimento do terço médio da face em pacientes com fissura labiopalatina tratados sem cirurgia ortognática aumentou a agradabilidade da face na opinião dos leigos com fissura labiopalatina.

Evaluation of condylar position in patients with malocclusion and changes in condylar position before and after orthodontic treatment using cone beam computed tomography / 口腔疾病防治

@#The functional health and stability of the oral and maxillofacial system is one of the basic goals of orthodontic treatment. Currently, it is believed that, in general, the condyle is located in the center of the joint fossa when the mandible is in an intercuspal position (ICP) in healthy normal people. At this time, the function of the temporomandibular joint (TMJ) is stable. Due to orthodontic tooth movement and subsequent occlusal changes, patients with malocclusion may experience related remodeling of the temporomandibular joint, especially changes in the position of the condyle. The position of the mandibular condyle is traditionally evaluated using a condylar position indicator. However, this method lacks consistency in obtaining condylar position changes. In recent years, in the clinical application of orthodontic treatment, cone beam computed tomography (CBCT) has become the first choice for examination. CBCT can accurately measure the interarticular space and determine changes in condylar position. This article reviews the CBCT assessment of condylar position and related research on condylar position changes in patients with malocclusion before and after orthodontic treatment. The literature review results indicate that there are differences in the condylar position of patients with different malocclusions, and the condylar position may also change before and after orthodontic treatment. With a lower radiation dose, CBCT has higher accuracy in evaluating the condylar position in patients with malocclusion who undergo orthodontic treatment, thus promoting further study of the mechanism of condylar position changes in patients with malocclusion in the future and providing more accurate and personalized guidance for patient treatment.

Trauma dental y lesiones faciales por armas de aire comprimido: reporte de un caso / Dental trauma and facial injuries by airguns: a case report

Las armas de aire comprimido son utilizadas desde hace muchos años con distintos usos que van desde el tiro recreativo hasta el control de plagas. Las más comunes son aquellas que disparan ''balines" o esferas metálicas que pueden llegar a tener capacidad de penetrar tejidos dependiendo del tipo de carga y de la longitud del cañón. Se presenta un caso clínico de un masculino que fue agredido con un arma tipo pistola con carga de CO2 que recibió un impacto a nivel facial y sufrió laceración en piel de labio y fractura dental complicada.

Air guns have been used for many years for a variety of purposes ranging from recreational shooting to pest control. The most common are those that shoot "pellets" or metallic spheres that can penetrate tissues depending on the type of load and the length of the barrel. A clinical case is presented of a male who was assaulted with a CO2-loaded pistol-type weapon, hit at facial level, and suffered laceration of the lip's skin and complicated dental fracture.

Neurosarcoidosis: inicio con compromiso de múltiples sitios neurológicos / Neurosarcoidosis: Onset with involvement of multiple neurological sites

Resumen Presentamos el caso de una mujer joven sana, que consultó por parálisis facial periférica izquierda asociada a fiebre, tos seca, disnea y astenia de dos semanas de evolución. Al examen físico se evidenció hipoestesia en dermatomas D6 a D12 izquierdos y galactorrea bi lateral. En el laboratorio presentaba serologías virales negativas, eritrosedimentación, títulos de anticuerpos antinucleares, prolactina y hormona tiroestimulante elevados, con anticuerpos antiperoxidasa positivos. La tomografía computarizada mostró múltiples adenopatías cervicales, mediastinales e hiliares bilaterales, sin com promiso del parénquima pulmonar. El cultivo de líquido cefalorraquídeo fue negativo para gérmenes comunes, micobacterias (Xpert MTB/RIF), y la citología no mostró atipia. Se realizó una resonancia magnética con con traste endovenoso de cerebro sin hallazgos patológicos y de columna con alteración de la señal centromedular de D6 a D9 de casi la totalidad del espesor del cordón, con refuerzo con contraste endovenoso. Durante la in ternación recuperó la sensibilidad en tronco izquierdo y no repitió episodios febriles o tusígenos. Se realizó mediastinoscopía con biopsia ganglionar con anatomía patológica con presencia de numerosos granulomas no caseificantes compatibles con sarcoidosis. Se clasificó como neurosarcoidosis probable e inició tratamiento con corticoides con mejoría de los síntomas neurológi cos restantes, realizándose una resonancia magnética a los tres meses, donde la alteración de la señal se limitaba desde D7 a D8. Nuestro objetivo es destacar la presentación neurológica en múltiples sitios que obligó a descartar otras entidades más frecuentes, así como la evolución favorable incluso previo al inicio de un esquema de tratamiento de primera línea.

Abstract We present the case of a healthy young woman who consulted for left peripheral facial palsy associated with fever, dry cough, dyspnea, and asthenia of two weeks' evolution. Physical examination revealed hypoesthesia in left T6 to T12 dermatomes and bilateral galactorrhea. In the laboratory, she presented negative viral serology, elevated erythrocyte sedimentation rate, antinuclear an tibody titers, prolactin and thyroid-stimulating hormone, with positive antiperoxidase antibodies. Computed to mography showed multiple bilateral cervical, mediastinal, and hilar adenopathies, without involvement of lung parenchyma. Cerebrospinal fluid culture was negative for common germs, mycobacteria, and Xpert MTB/RIF, and cytology did not show atypia. Contrast-enhanced magnetic resonance was performed on the brain without pathological findings and on the spine with alteration of the centromedullary signal from T6 to T9 of almost the entire thickness of the cord, with posterior enhancement with gadolinium. During hospitalization, she recovered sensitivity in the left trunk and did not repeat febrile or cough episodes. She was referred to another center for mediastinoscopy with lymph node biopsy revealing the presence of numerous non-caseating granulomas compatible with sarcoidosis. It was classified as probable neurosarcoidosis and started treatment with corticoste roids with improvement of the remaining neurological symptoms. A magnetic resonance was performed three months later where the signal alteration was limited from T7 to T8. Our objective is to highlight the florid neu rological presentation that made it necessary to rule out other more frequent entities and the favorable evolution even before starting a first-line scheme of treatment.

Anatomical Characteristics, Relations, and Clinical Considerations of the Facial Index and Cephalic Index in Young Chileans Aged Between 18 and 21 Years / Características Anatómicas, Relaciones y Consideraciones Clínicas del Índice Facial e Índice Cefálico en Jóvenes Chilenos entre 18 y 21 Años

SUMMARY: Humans throughout history have shown similarities between both their cephalic and facial complexion, among certain ethnic groups, due to genetic and demographic factors. Several studies have demonstrated the different constitutions of specific groups of people in order to generate data of a certain population or group. The present research aims to preliminarily study the existence of possible relations between Cephalic Index and Facial Index among categories of individuals in an odontology student population from a private university in Santiago, Chile. Empirical, descriptive, and cross-sectional study. In this study, 129 students with age range 18-21 were taken as subjects in a non-probabilistic way. Regarding Cephalic Index (CI), the Retzius classification was used, and the Facial Index (FI) was measured considering the maximum height of the face, from nasion to gnathion (Na-Gn), and the maximum width, from right zygion to left zygion (Zr-Zl). In this study, 129 people were taken as sample, 82 females and 47 males. Among women, the most predominant cephalic biotype was brachycephalic (59.8 %), followed by mesocephalic (37.8 %), and dolichocephalic (2.4 %). On the other hand, men's most common biotype was mesocephalic (57.5 %), followed by brachycephalic (36.2 %), and dolichocephalic (6.4 %). Regarding facial biotype, both in female and male subjects the following pattern was shown: euryprosopic (F: 59.7 %, M: 59.6 %), mesoprosopic (F: 26.8 %, M: 29.8 %), and leptoprosopic (F: 13.4 %, M: 10.6 %). Facial parameters of the subjects (odontology students from a Chilean university) tend to be mostly euryprosopic, followed by mesoprosopic and leptoprosopic. Additionally, mesocephalic biotypes tend to be similar to other studies conducted in Chile.

Los seres humanos a lo largo de la historia han mostrado similitudes tanto entre su complexión cefálica como facial, entre ciertos grupos étnicos, debido a factores genéticos y demográficos. Varios estudios han demostrado las diferentes constituciones de grupos específicos de personas para poder generar datos de una determinada población o grupo. La presente investigación tiene como objetivo estudiar preliminarmente la existencia de posibles relaciones entre el Índice Cefálico y el Índice Facial entre categorías de individuos en una población de estudiantes de odontología de una universidad privada de Santiago, Chile, en un estudio empírico, descriptivo y transversal. En este estudio, se tomó como sujetos de forma no probabilística a 129 estudiantes con edades comprendidas entre 18 y 21 años. Respecto al Índice Cefálico (IC), se utilizó la clasificación de Retzius, y el Índice Facial (FI) se midió considerando la altura máxima de la cara, desde nasión hasta gnatión (Na-Gn), y el ancho máximo, desde cigio derecho a izquierdo. cigio (Zr-Zl). En este estudio se tomó como muestra 129 personas, 82 mujeres y 47 hombres. Entre las mujeres, el biotipo cefálico más predominante fue el braquicéfalo (59,8 %), seguido del mesocefálico (37,8 %) y el dolicocéfalo (2,4 %). Por otro lado, el biotipo más común en los hombres fue el mesocefálico (57,5 %), seguido del braquicéfalo (36,2 %) y el dolicocéfalo (6,4 %). Respecto al biotipo facial, tanto en sujetos femeninos como masculinos se mostró el siguiente patrón: euriprosópico (F: 59,7 %, M: 59,6 %), mesoprosópico (F: 26,8 %, M: 29,8 %) y leptoprosópico (F: 13,4 %, M: 10,6 %). Los parámetros faciales de los sujetos (estudiantes de odontología de una universidad chilena) tienden a ser en su mayoría euriprosópicos, seguidos de mesoprosópicos y leptoprosópicos. Además, los biotipos mesocefálicos tienden a ser similares a otros estudios realizados en Chile.

SUMMARY: Orthognathic surgery and rhinoplasty show synergy in terms of function and aesthetic results. The aim of this research is to analyze variables related to simultaneous orthognathic surgery and rhinoplasty and to discuss the surgical sequence. Male and female subjects between 18 and 45 years old were included in this research. Diagnosis related to nasal morphology (nasal tip bifid, rotate, square and others as well as the alae morphology and columella), facial deformity (sagittal and vertical deformity), type of surgery (rhinoplasty techniques and orthognathic techniques) and complications were included. The minimum follow-up was 12 months; Chi- Square and t test were used to define correlations, considering a value of p<0.05 for statistical significance. Class III facial deformity was observed in 40 % of subjects and class II facial deformity was present in 43 %. For the nasal deformities, the tip and nasal bridge were most prevalent; primary nasal deformity was observed in the 83 % of subjects and was significant more than secondary nasal deformity (p=0.042). Bimaxillary surgery was performed in 31 cases (88 %). In 10 cases a change of the original plan for rhinoplasty due to previous maxillary surgery was realized, mainly in class III facial deformity, with no statistical differences. Revision rhinoplasty was realized in 5 cases (14 %) and was not related to surgical variables; revision for orthognathic surgery was not necessary in this series. Rhinoplasty and orthognathic surgery simultaneously show low complications and predictable results. We can conclude that maxillary mandibular osteotomies and rhinoplasty could be performed safely. However, larger studies are necessary to understand the best choice and variables involved in simultaneous procedures and soft tissue response.

La cirugía ortognática y la rinoplastia muestran sinergia en términos de resultados funcionales y estéticos. EL objetivo de esta investigación es analizar variables relacionadas con la cirugía ortognática y rinoplastia ejecutada de forma simultanea. Fueron incluidos hombres y mujeres entre 18 y 45 años de edad. EL diagnóstico fue en base a la morfología nasal (punta bífida, rotada, cuadrada u otras así como alteraciones del ala nasal y columela), deformidad facial (deformidad sagital y vertical), tipo de cirugía (técnica de rinoplastia y cirugía ortognática) y complicaciones asociadas. El seguimiento mínimo fue de 12 meses; se utilizo las prueba t test y chi cuadrado para definir relaciones estadísticas considerando un valor de p< 0,05 para obtener diferencias significativas. La deformidad clase III fue observada en el 40 % de los sujetos y la deformidad facial de clase II se presento en el 43 %. Para la deformidad nasal, las alteraciones de a punta nasal y nasal fueron mas prevalentes; la deformidad nasal primaria se presentó en el 83 % de los sujetos y fue significativamente mayor que la deformidad nasal secundaria (p=0,042). La cirugía bimaxilar se realizó en 31 casos (88 %); en 10 casos se realizó el cambio del plan quirúrgico inicial de la rinoplastia debido a cambios generados en la cirugía maxilar previa, mayormente en deformidad facial de clase III, sin presentar diferencias significativas. La rinoplastia de revisión fue realizada en 5 casos (14 %) y no fue relacionada con ninguna variable de tipo quirúrgica; la revisión de cirugía ortognática no fue realizada en ningún caso de esta serie. La rinoplastia y la cirugía ortognática simultanea mostraron bajas complicaciones y resultados predecibles. Se puede concluir que la osteotomía maxilo mandibular y la rinoplastia son seguras; sin embargo, estudios de mayor volumen son necesarios para entender la mejor opción y variables relacionadas con procedimientos simultáneos y la respuesta de tejidos blandos faciales.

Fratura de mandíbula: análise de 50 casos cirúrgicos em um hospital escola / Jaw fracture: analysis of 50 surgical cases in a teaching hospital

Introdução: A mandíbula é o maior e mais forte dos ossos da face. Em razão de sua topografia, apresenta vulnerabilidade nos traumas. A análise de dados sobre as fraturas de mandíbula se mostram fundamentais para auxiliar no tratamento e em políticas de saúde pública. O objetivo desse estudo é realizar um levantamento epidemiológico de fraturas mandibulares tratadas cirurgicamente. Método: Triagem através do sistema de informação hospitalar, buscando pacientes submetidos a cirurgia para fratura de mandíbula realizadas em um hospital escola pela equipe de cirurgia plástica, em Campinas-SP, de abril de 2015 a abril de 2020. Foram, então, coletados dados por meio da análise de prontuários. Resultados: Foram incluídos 50 pacientes, sendo 90% do sexo masculino. A média de idade foi 30,7 anos. A etiologia predominante foi acidente automotivo e a região mais fraturada na mandíbula foi a parassínfise. A mediana de tempo entre o trauma e cirurgia foi de 19 dias. Onze (22%) pacientes apresentavam alguma comorbidade. Quatorze pacientes (28%) foram internados em Unidade de Terapia Intensiva (UTI) e 42% operaram com outra especialidade além da Cirurgia Plástica. Dez (20%) pacientes apresentaram alguma complicação da cirurgia, sendo a mais comum a deiscência de ferida operatória. Conclusão: Houve predominância entre homens jovens e de acidentes de trânsito como etiologia. As fraturas foram localizadas preferencialmente na região da parassínfise e foram tratadas por meio de fixação interna rígida. Os elevados índices de internação em UTI, lesões associadas e realizações de procedimentos cirúrgicos por outras especialidades evidenciam a gravidade dos pacientes assistidos no serviço.

Introduction: The mandible is the largest and strongest of the bones in the face. Due to its topography, it is vulnerable to trauma. Data analysis on mandible fractures is fundamental for treatment and public health policies. This study aims to conduct an epidemiological survey of surgically treated mandibular fractures. Method: Screening through the hospital information system, seeking patients undergoing surgery for jaw fracture performed at a teaching hospital by the plastic surgery team in Campinas-SP from April 2015 to April 2020. Data were then collected through analysis of medical records. Results: 50 patients were included, 90% male. The average age was 30.7 years. The predominant etiology was an automobile accident, and the most fractured region in the mandible was the parasymphysis. The median time between trauma and surgery was 19 days. Eleven (22%) patients had some comorbidity. Fourteen patients (28%) were admitted to the Intensive Care Unit (ICU), and 42% underwent surgery with another specialty besides Plastic Surgery. Ten (20%) patients had some complication of the surgery, the most common being surgical wound dehiscence. Conclusion: There was a predominance among young men and traffic accidents as etiology. Fractures were preferably located in the parasymphysis region and were treated using rigid internal fixation. The high rates of ICU admission, associated injuries, and surgical procedures carried out by other specialties demonstrate the severity of the patients assisted in the service.

Beliefs and concerns about pain were associated with craniofacial pain experienced within 24 hours: cross-sectional study / Crenças e preocupações sobre a dor têm associação à dor craniofacial experimentada nas últimas 24 horas: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Although craniofacial pain has been associated with negative psychological aspects, how the patient's perception of their own illness could influence craniofacial pain is not elucidated yet. Therefore, this study aims to identify the main factors and beliefs about the illness that could influence pain intensity and pain duration in people who experienced craniofacial pain in the last 24 hours. METHODS: This cross-sectional study comprised undergraduate students, aged between 18 and 40 years old, who experienced self-reported craniofacial pain in the last 24 hours. Participants answered questions regarding body functions, activities and participation, and personal factors based on the International Classification of Functioning (ICF); In addition, questions from the Brief Illness Perceptual Questionnaire (Brief IPQ) were applied. The analysis was carried out with a single and multiple regression model. RESULTS: The sample comprised 87 volunteers. Pain intensity and duration experienced in the last 24 hours were associate by concerns about the presence of an illness and the need for treatment. Pain intensity was specifically associated with the importance of treatment and the extent to which the patient is concerned about their pain (R2=0.108). Pain duration was associated with how much the individual is worried about their illness (R2=0.1459). CONCLUSION: Both pain intensity and duration experienced in the last 24 hours are associated with concerns regarding the presence of an illness and beliefs related to such illness treatment, which reinforces the influence of psychosocial aspects on pain perception.

RESUMO JUSTIFICATIVA E OBJETIVOS: Embora a dor craniofacial seja associada a aspectos psicológicos negativos, ainda não está totalmente elucidado como a percepção do paciente sobre sua própria doença pode influenciá-la. Portanto, este estudo teve como objetivo identificar os principais fatores e as crenças sobre a doença que podem influenciar a intensidade e a duração da dor em pessoas que sentiram dor craniofacial nas últimas 24 horas. MÉTODOS: Estudo transversal composto por universitários, com idade entre 18 e 40 anos, que relataram dor craniofacial nas últimas 24 horas. Os voluntários responderam a perguntas sobre funções corporais, atividades e participação e fatores pessoais com base na classificação da Classificação Internacional de Funcionalidades (CIF). Além disso, foram aplicadas questões do Questionário de Percepção de Doenças Versão Breve (Brief IPQ). A análise foi realizada com um modelo de regressão simples e múltiplo. RESULTADOS: A amostra foi composta por 87 voluntários. A intensidade e a duração da dor sentida nas últimas 24 horas foram influenciadas pela preocupação com a presença de doença e com a necessidade de tratamento. A intensidade da dor foi associada à importância do tratamento e à preocupação do paciente com sua dor (R2=0,108). A duração da dor associou-se à preocupação do indivíduo com sua doença (R2=0,1459). CONCLUSÃO: Tanto a intensidade quanto a duração da dor vivenciadas nas últimas 24 horas são influenciadas pela preocupação com a presença de doença e crenças relacionadas ao seu tratamento, o que reforça a influência dos aspectos psicossociais na percepção da dor.

Post-parotidectomy facial nerve function: comparison between original and modified Sunnybrook Facial Grading Systems / Função do nervo facial pós-parotidectomia: comparação entre os Sistemas Sunnybrook de Graduação Facial original e modificado

Abstract Background: Facial nerve dysfunction is the principal postoperative complication related to parotidectomy. Objective: To test the hypothesis that the modified Sunnybrook Facial Grading System (mS-FGS) is superior to the original S-FGS in the assessment of facial nerve function following parotidectomy. Methods: Prospective, longitudinal study evaluating patients with primary or metastatic parotid neoplasms undergoing parotidectomy with facial nerve-sparing between 2016 and 2020. The subjects were assessed twice, on the first postoperative day and at the first outpatient evaluation, 20-30 days post-surgery. Facial assessments were performed using the original and modified (plus showing the lower teeth) versions of the Sunnybrook System and documented by pictures and video recordings. Intra- and inter-rater agreements regarding the assessment of the new expression were analyzed. Results: 101 patients were enrolled. In both steps, the results from the mS-FGS were significantly lower (p < 0.001). Subjects with a history of previous parotidectomy and those who underwent neck dissection had more severe facial nerve impairment. The mandibular marginal branch was the most frequently injured, affecting 68.3% of the patients on the first postoperative day and 52.5% on the first outpatient evaluation. Twenty patients (19.8%) presented an exclusive marginal mandibular branch lesion. The inter-rater agreement of the new expression assessment ranged from substantial to almost perfect. The intra-rater agreement was almost perfect (wk = 0.951). Conclusion: The adoption of the Modified Sunnybrook System, which includes evaluation of the mandibular marginal branch, increases the accuracy of post-parotidectomy facial nerve dysfunction appraisal.

Resumo Antecedentes: A disfunção do nervo facial é a principal complicação pós-operatória relacionada à parotidectomia. Objetivo: Testar a hipótese de que o sistema Sunnybrook de graduação facial modificado (mS-FGS) é superior ao S-FGS original na avaliação da função do nervo facial após parotidectomia. Métodos: Estudo longitudinal prospectivo avaliando o pós-operatório de pacientes com neoplasias parotídeas primárias ou metastáticas, submetidos à parotidectomia com preservação do nervo facial, entre 2016 e 2020. Os indivíduos foram avaliados duas vezes, no primeiro dia de pós-operatório e na primeira avaliação ambulatorial, 20-30 dias após a cirurgia. As avaliações faciais foram realizadas usando as versões original e modificada (que incluem mostrar os dentes inferiores) do sistema Sunnybrook e documentadas por fotos e vídeos. Foram adicionalmente analisadas as concordâncias intra e interexaminadoras da avaliação da nova expressão. Resultados: Cento e um pacientes foram incluídos. Em ambas as etapas, os resultados do mS-FGS foram significativamente menores (p < 0,001). Indivíduos com história de parotidectomia prévia e aqueles submetidos ao esvaziamento cervical apresentaram comprometimento mais grave do nervo facial. O ramo marginal mandibular foi o mais afetado, acometendo 68,3% dos pacientes no primeiro dia de pós-operatório e 52,5% na primeira avaliação ambulatorial. Vinte pacientes (19,8%) apresentaram lesão exclusiva do ramo marginal mandibular. A concordância interexaminadores da avaliação da nova expressão variou de substancial a quase perfeita. A concordância intraexaminador foi quase perfeita (wk = 0,951). Conclusão: A adoção do sistema Sunnybrook modificado, que inclui a análise do ramo marginal mandibular, aumenta a precisão da avaliação da disfunção do nervo facial pós-parotidectomia.

Face, facial recognition technology and personal privacy

The privacy problem of facial recognition technology is that commercial companies obtain people's facial information without the consent of individuals and use facial information to infringe on the privacy of individuals. The importance of human privacy in facial recognition technology is reflected through facial ethics, which requires others to perform corresponding obligations to individuals, such as oral care. Through the analysis of the privacy issues of facial recognition technology, it is found that the two elements of "without personal informed" and "without personal consent" together form the basis for commercial companies to violate personal privacy. The principle of informed consent includes the principle of informed and the principle of consent, which is derived from the principle of informed consent in medical ethics. This paper improves the principles of informed consent in medicine and ethics to better address facial recognition privacy issues.

El problema de la privacidad en la tecnología de reconocimiento facial es que las empresas comerciales obtienen información facial de las personas sin el consentimiento de éstas y utilizan la información facial para vulnerar la privacidad de las personas. La importancia de la privacidad de las personas en la tecnología de reconocimiento facial se refleja a través de la ética facial, que exige que otros cumplan las obligaciones correspondientes con los individuos, como el cuidado bucal. A través del análisis de los problemas de privacidad de la tecnología de reconocimiento facial se descubre que los dos elementos de "sin información personal" y "sin consentimiento personal" juntos forman la base para que las empresas comerciales violen la privacidad personal. El principio de consentimiento informado incluye el de información y el de consentimiento, que se deriva del principio de consentimiento informado de la ética médica. Este artículo mejora los principios del consentimiento informado en medicina y ética para abordar mejor los problemas de privacidad del reconocimiento facial.

A questão da privacidade na tecnologia de reconhecimento facial é que as companhias comerciais obtém informações faciais das pessoas sem seu consentimento e usam informação facial para infringir sua privacidade. A importância da privacidade humana na tecnologia de reconhecimento facial é refletida através da ética facial, que exige que se cumpram obrigações correspondentes para com os indivíduos, da mesma forma como com cuidados orais. Através da análise de aspectos de privacidade na tecnologia de reconhecimento facial, encontrou-se que os dois elementos "sem informação pessoal" e "sem consentimento pessoal" juntos, formam a base para companhias comerciais violarem a privacidade pessoal. O princípio do consentimento informado inclui o princípio de informação e o princípio de consentimento, os quais derivam do princípio do consentimento informado em ética médica. Esse artigo melhora os princípios do consentimento informado em medicina e ética para melhor incluir aspectos de privacidade no reconhecimento facial.

Characterization of Salivary Gland Pain: A Review of the Literature / Caracterización del Dolor de Glándulas Salivales: Revisión de la Literatura

SUMMARY: The salivary glands in pathological conditions produce countless different clinical presentations, and due to their complex neuroanatomy, their pain symptoms vary widely. However, in the literature to date, few studies characterize salivary gland pain. The aim of this study was to conduct a literature review concerning the clinical characteristics of pain in various salivary gland pathologies. A literature review was done through a systematic search of scientific articles in the Web of Science (WoS), MEDLINE, Scopus, and Elton B. Stephens Company (EBSCO) databases. The free terms "salivary gland", "parotid gland", "submaxillary gland", "sublingual gland", and "pain" were used along with the Boolean operators OR and AND. The search yielded a total of 1896 articles, of which 60 fulfilled the inclusion criteria and were ultimately included in this review. It is described that pain is a nonspecific symptom of a glandular pathology and is characterized mainly by the location of the pain, which is correlated with the anatomical location of the affected salivary gland. Among the painful salivary gland pathologies, we found inflammatory disorders, including infections, obstructions, disorders secondary to hyposalivation; systemic autoimmune diseases; neoplasms, and neuropathic pain disorders. The diagnosis and management of salivary gland pain require knowledge of the causes and mechanisms of the pain, and it is to recognize the signs and symptoms of salivary gland disorders to be able to diagnose and treat them.

Las glándulas salivales en condiciones patológicas producen un sinfín de presentaciones clínicas diferentes, y debido a su compleja neuroanatomía generan variaciones en su sintomatología dolorosa. Sin embargo, en la literatura hasta ahora son escasos los estudios que caracterizan el dolor de glándulas salivales. El objetivo de este estudio fue realizar una revisión de la literatura respecto a las características clínicas del dolor en diversas patologías de glándulas salivales. Se realizó una revisión de la literatura, a través de la búsqueda sistemática de artículos científicos en las bases de datos Web of Science (WoS), MEDLINE, Scopus y Elton B. Stephens Company (EBSCO). A través de los términos libres: "salivary gland", "parotid gland", "submaxillary gland", "sublingual gland", "pain", junto con los operadores booleanos OR y AND. La búsqueda arrojó un total de 1896 artículos, de los cuales 60 cumplieron los criterios de inclusión y fueron finalmente incluidos en esta revisión. Se describe que el dolor es un síntoma poco específico para la patología glandular y está caracterizado principalmente por la localización del dolor, el cual se correlaciona con la ubicación anatómica de la glándula salival afectada. Dentro de las patologías dolorosas de glándulas salivales encontramos los trastornos inflamatorios, incluidas infecciones, obstrucciones, trastornos secundarios a hiposalivación; enfermedades sistémicas autoinmunes; neoplasias y trastornos de dolor neuropático. El diagnóstico y manejo del dolor de glándulas salivales requiere del conocimiento de las causas y mecanismos del dolor, siendo necesario reconocer los signos y síntomas de los trastornos de glándulas salivales para ser capaces de diagnosticarlos y tratarlos.

Lower Four Cranial Nerves in the Management of Glomus Jugulare: Anatomical Study

Abstract Introduction The surgical management that achieves minimal morbidity and mortality for patients with glomus and non-glomus tumors involving the jugular foramen (JF) region requires a comprehensive understanding of the complex anatomy, anatomic variability, and pathological anatomy of this region. Objective The aim of this study is to propose a rational guideline to expose and preserve the lower cranial nerves (CNs) in the lateral approach of the JF. Methods The technique utilized is the gross and microdissection of 4 fixed cadaveric heads to revise the JF's surgical anatomy and high part of the carotid sheath compared with surgical cases to understand and preserve the integrity of lower CNs. The method involves radical mastoidectomy, microdissection of the JF, facial nerve, and high neck just below the carotid canal and the JF. The CNs IX, X, XI, and XII are microscopically dissected and kept in sight up to the JF. Results This study realized well the surgical and applied anatomy of the lower CNs with relation to the facial nerve and JF. Conclusions The JF anatomy is complicated, and the key to safely operate on it and preserving the lower CNs is to find the posterior belly of the digastric muscle, to skeletonize the facial nerve, to remove the mastoid tip preserving the stylomastoid foramen, to skeletonize the sigmoid sinus and posterior fossa dura not only anterior but also posteroinferior to reach and drill the jugular tubercle.
