RESUMO
Introducción: El mito de rejuvenecer o ser bello eternamente es un sueño que la humanidad siempre ha compartido en muchas leyendas. Objetivo: Evaluar los resultados de la lipotransferencia por decantación asistida con células madre del tejido adiposo para el rejuvenecimiento facial. Métodos: Se realizó un estudio descriptivo, prospectivo y longitudinal de 35 pacientes seleccionados por muestreo aleatorio simple, en el Servicio de Cirugía Plástica del Hospital Hermanos Ameijeiras de La Habana, desde septiembre de 2019 hasta igual periodo de 2022. Resultados: En la casuística, la edad media fue de 46,5 ± 11,5 años con valores mínimo de 34 y máximo de 57 años; 48,6 % se encontraban en el grupo etario de 50-59 años. Se constató un predominio del fototipo cutáneo II (60,0 %); en pacientes sanos, el mayor porcentaje con grado de envejecimiento fue el de tipo III (57,1 %). Prevalecieron las arrugas finas en reposo y líneas más profundas con expresión facial (40,0 %) en quienes recibirían lipotransferencia asistida. Posterior al tratamiento se constató mejoría en todos los pacientes; ninguno presentó complicación. La evaluación de este procedimiento resultó ser buena (94,3 %). Conclusiones: La lipotransferencia es un procedimiento mínimamente invasivo con ventajas en cuanto a histocompatibilidad, durabilidad y menor número de complicaciones; tiene una elevada tasa de aceptación. El resultado final favorable, la seguridad y la efectividad se observan en la satisfacción del paciente.

RESUMO
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.

RESUMO
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

RESUMO
Introdução: Os estudos de anatomia em cadáveres permitiram um melhor entendimento das estruturas da face e, consequentemente, mais segurança ao explorar os planos profundos da região facial. Uma boa técnica deve ser segura, reprodutível e respeitar os pontos anatômicos. O objetivo deste trabalho é desmistificar a técnica de deep plane facelifting por meio da dissecção de cadáveres e exposição das estruturas faciais. Método: A reprodução da técnica de "deep plane facelifting" foi realizada em 14 hemifaces de 7 peças de cadáveres frescos no Instituto de Treinamento de Cadáver em Curitiba no ano de 2021. A técnica cirúrgica foi realizada conforme nossa prática clínica e reproduzida no cadáver. Após o procedimento, as estruturas anatômicas faciais foram dissecadas para correlacionar seu posicionamento junto aos espaços anatômicos da face. Foram avaliados os posicionamentos dos ligamentos da face, vascularização e os ramos do nervo facial. Resultados: Foram identificados os espaços anatômicos relevantes à técnica de deep plane facelifting, como os espaços massetéricos inferior e superior, espaço pré-zigomático, espaço bucal e espaço cervical. Os ramos do nervo facial foram identificados no plano subSMAS e correlacionados com os espaços e planos anatômicos. Conclusão: A técnica de deep plane facelift pode ser reproduzida com segurança desde que sejam respeitados dois parâmetros. O primeiro é a entrada correta nos espaços a fim de respeitar a anatomia. O segundo é o uso de descoladores rombos para dissecção nos planos profundos da face a fim de evitar lesão nervosa dos ramos do nervo facial.
Introduction: Anatomy studies on cadavers have allowed a better understanding of the structures of the face and, consequently, greater safety when exploring the deep planes of the facial region. A good technique must be safe, reproducible, and respect anatomical points. The objective of this work is to demystify the deep plane facelifting technique through the dissection of cadavers and exposure of facial structures. Method: The reproduction of the "deep plane facelifting" technique was performed on 14 hemifaces of 7 pieces of fresh cadavers at the Instituto de Treinamento de Cadáver (Cadaver Training Institute) in Curitiba in 2021. The surgical technique was performed according to our clinical practice and reproduced on the cadaver. After the procedure, the facial anatomical structures were dissected to correlate their positioning with the anatomical spaces of the face. The positioning of the facial ligaments, vascularization, and branches of the facial nerve were evaluated. Results: The anatomical spaces relevant to the deep plane facelifting technique were identified, such as the inferior and superior masseteric spaces, prezygomatic space, buccal space, and cervical space. The facial nerve branches were identified in the sub-SMAS plane and correlated with the anatomical spaces and planes. Conclusion: The deep plane facelift technique can be reproduced safely as long as two parameters are respected. The first is the correct entry into spaces to respect the anatomy. The second is the use of blunt detachers for dissection in the deep planes of the face to avoid nerve damage to the branches of the facial nerve.

Resultados el 46,34 % de los pacientes presentó una clase II esquelética maxilomandibular. Mediante el índice VERT de Ricketts, el 49,59 % de los casos fue clasificado como dolicofacial, seguido del 42,27 % como braquifacial. El 83,60 % de los pacientes con biotipo dolicofacial se caracterizó por presentar una clase II esquelética maxilomandibular, y el 76,92 % de aquellos con biotipo braquifacial clasificó como clase III. Se encontró una asociación significativa entre el biotipo facial y la clasificación esquelética maxilomandibular (p= 0,000). Conclusiones en la mayoría de los pacientes con anomalías dentomaxilofaciales se evidenció una relación entre el biotipo dolicofacial y la clase II esquelética maxilomandibular, por lo que existe una comorbilidad entre ambas características esqueléticofaciales.
Foundation cephalometric measurements are a useful instrument in orthodontic care, since together with other cephalometric measurements they complete and guide the treatment plan that the specialist can draw up based on the resolution of dentomaxillofacial anomalies. Objective to determine the comorbidity between facial biotype and maxillomandibular skeletal classification in Angolan patients with dentomaxillofacial anomalies. Methods a cross-sectional descriptive study was carried out at the Meditex Clinic, in Luanda, Angola, from August/2021 to July/2023. The studied population was 123 patients' profile teleradiographs with dentomaxillofacial anomalies, admitted to the Orthodontic clinic. For the analysis of the profile teleradiography, measurements of the Ricketts and Steiner cephalogram were made, and the Facad software version 3403 was used. The maxillomandibular skeletal classification (class I, class II, class III) and the facial biotype (dolichofacial, mesofacial, brachyfacial) were studied. Results 46.34% of patients presented maxillomandibular skeletal class II. Using the Ricketts VERT index, 49.59% of cases were classified as dolichofacial, followed by 42.27% as brachyfacial. 83.60% of patients with dolichofacial biotype were characterized by having maxillomandibular skeletal class II, and 76.92% of those with brachyfacial biotype were classified as class III. A significant association was found between facial biotype and maxillomandibular skeletal classification (p= 0.000). Conclusions in the majority of patients with dentomaxillofacial anomalies, a relationship was evident between the dolichofacial biotype and the maxillomandibular skeletal class II, so there is a comorbidity between both skeletal-facial characteristics.

RESUMO
OBJECTIVES@#To compare the clinical effect on Bell's facial palsy in the acute stage between the staging comprehensive treatment with acupuncture-moxibustion and western medication.@*METHODS@#Sixty patients with Bell's facial palsy in the acute stage were randomly divided into an observation group and a control group, with 30 cases in each one. The patients in the control group were administered orally with prednisone acetate tablets and methylcobalamin tablets until the 28th day of illness. In the observation group, the staging comprehensive treatment with acupuncture-moxibustion was adopted. On the affected side, Qianzheng (EX-HN 16), Yifeng (TE 17), Sibai (ST 2), Yangbai (GB 14), Jiache (ST 6), Dicang (ST 4) and Touwei (ST 8), etc. were stimulated. In the acute stage (Day 1 to 7 of illness), the routine acupuncture and the point-toward-point needle insertion were delivered, no any manipulation was exerted at acupoints, and the needles were retained for 30 min. In the subacute stage (Day 8 to 14 of illness), on the base of the treatment as the acute stage, the depth of needle insertion was adjusted at a part of acupoints and the even needling technique was operated by twisting needle. Besides, electroacupuncture (EA) was attached to Qianzheng (EX-HN 16) and Dicang (ST 4), with continuous wave of low intensity and high frequency, 100 Hz, for 20 min. In the recovery stage (Day 15 to 28 of illness), on the base of the treatment as the subacute stage, the heavy stimulation of acupuncture was given, in which, the sticking and lifting needle techniques were delivered after the needles were inserted from Sibai (ST 2) toward Dicang (ST 4), and from Dicang (ST 4) toward Jiache (ST 6), separately; warm needling was operated at Yifeng (TE 17), and EA changed to stimulate the acupoints with the intermittent wave of high intensity and low frequency, 2 Hz, for 30 min. Acupuncture-moxibustion was given once every other day until the end of the 28th day of illness. The level of House-Brackmann facial nerve function rating scale (H-B grade),the score of Sunnybrook facial nerve grading system (Sunnybrook), the score of facial disability index (FDI), the temperature difference in the infrared thermal imaging facial area and electromyogram (EMG) situation of the affected muscle group were observed before and after treatment in the two groups. Using musculoskeletal ultrasound,the facial nerve diameter was detected and the clinical effect was compared between the two groups.@*RESULTS@#After treatment, the level of H-B grade, Sunnybrook score, the scores of physical function and social life function in FDI were improved when compared with those before treatment in the patients of either group (P<0.01, P<0.05), and the results of these evaluations in the observation group were better than those of the control group (P<0.05). After treatment, the temperature difference of the frontal area, the eye area, the zygomatic area and the mouth corner was declined in comparison with that before treatment in the two groups (P<0.05), and the temperature difference in each area in the observation group was lower than that of the control group (P<0.05).The root mean square (RMS) of the frontal muscle group, the zygomatic muscle group and the orbicularis muscle group on the affected side increased in comparison with that before treatment in the two groups (P<0.01), and RMS of the observation group was higher than that of the control group (P<0.05) after treatment. Before treatment, the diameter of the facial nerve on the affected side was larger than that on the healthy side (P<0.01), and after treatment, the diameter on the affected side was reduced when compared with that before treatment in the two groups (P<0.01); the diameter of the facial nerve on the affected side in the observation group was smaller than that of the control group (P<0.05), while, the diameter on the affected side was larger when compared with the healthy side in the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), higher than that of the control group (83.3% [25/30], P<0.05).@*CONCLUSIONS@#The staging comprehensive treatment with acupuncture-moxibustion is clearly effective on Bell's facial palsy in the acute stage, which affirms the effectiveness of acupuncture-moxibustion for the acute stage of Bell's facial palsy in comparison with conventional western medication.

@#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.
RESUMO
OBJECTIVE@#To explore the mechanism of electroacupuncture (EA) in promoting recovery of the facial function with the involvement of autophagy, glial cell line-derived neurotrophic factor (GDNF), and phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) signaling pathway.@*METHODS@#Seventy-two male Sprague-Dawley rats were randomly allocated into the control, sham-operated, facial nerve injury (FNI), EA, EA+3-methyladenine (3-MA), and EA+GDNF antagonist groups using a random number table, with 12 rats in each group. An FNI rat model was established with facial nerve crushing method. EA intervention was conducted at Dicang (ST 4), Jiache (ST 6), Yifeng (SJ 17), and Hegu (LI 4) acupoints for 2 weeks. The Simone's 10-Point Scale was utilized to monitor the recovery of facial function. The histopathological evaluation of facial nerves was performed using hematoxylin-eosin (HE) staining. The levels of Beclin-1, light chain 3 (LC3), and P62 were detected by immunohistochemistry (IHC), immunofluorescence, and reverse transcription-polymerase chain reaction, respectively. Additionally, IHC was also used to detect the levels of GDNF, Rai, PI3K, and mTOR.@*RESULTS@#The facial functional scores were significantly increased in the EA group than the FNI group (P<0.05 or P<0.01). HE staining showed nerve axons and myelin sheaths, which were destroyed immediately after the injury, were recovered with EA treatment. The expressions of Beclin-1 and LC3 were significantly elevated and the expression of P62 was markedly reduced in FNI rats (P<0.01); however, EA treatment reversed these abnormal changes (P<0.01). Meanwhile, EA stimulation significantly increased the levels of GDNF, Rai, PI3K, and mTOR (P<0.01). After exogenous administration with autophagy inhibitor 3-MA or GDNF antagonist, the repair effect of EA on facial function was attenuated (P<0.05 or P<0.01).@*CONCLUSIONS@#EA could promote the recovery of facial function and repair the facial nerve damages in a rat model of FNI. EA may exert this neuroreparative effect through mediating the release of GDNF, activating the PI3K/mTOR signaling pathway, and further regulating the autophagy of facial nerves.

Congenital cranial dysinnervation disorders(CCDDs)are a group of diseases with congenital non-progressive developmental abnormalities or absence of one or more cranial nerves, resulting in primary or secondary abnormalities of cranial nerves innervating the extraocular muscles. CCDDs can be sporadic or hereditary, and may be accompanied by systemic abnormalities. In recent years, with the research progress of neuropathology, neuroimaging, and genetics, it has not only been clarified that the cause of eye movement disorder in CCDDs is neurogenic, but also been found the pathogenic genes of CCDDs, including SALL4, HOXA1, KIF21A, PHOX2A, TUBB3, and HOXB1, etc. In this review, the relevant domestic and international literatures on the molecular genetics and neuroscience of CCDDs in recent years are reviewed, aiming to address how the causing gene mutations of CCDDs affect brain neural development and further lead to congenital abnormal cranial nerve innervation, in order to provide references for the clinical and basic research of CCDDs.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
The theory of “diagnosing diseases with sinews” means that through the diagnosis and examination of the channel sinews at the site of the lesion, the surplus and deficit state of qi and blood in the channel sinews, vessles and channels, and the degree of damage to the organism caused by the disease and evils, can be determined, forming the three elements (the nature of the disease, the location of the disease, and the disease tendency) of the disease diagnosis can be closely integrated to form the trinity of diagnostic modes, which is “examining the disease nature by sinews, identifying the pattern by sinews, and determining the tendency by sinews”. For intractable facial paralysis, the method of “diagnosing diseases with sinews” can be adopted, in which the morphological changes of the channel sinews are judged through diagnosis by observation, the traditional Chinese patterns are identified through diagnosis by palpation, and the points of meridian tendons and the circulation of tendon and treatment lines are determined through diagnosis by circulation. The “diagnosing diseases with sinews” not only helps to accurately determine the disease condition, patterns and development trend, but also helps to adopt targeted treatment for the disease and prevent the disease from spreading, and providing ideas and methods for the clinical diagnosis and treatment of intractable facial paralysis.
RESUMO
Objective@#To investigate the clinical efficacy of disc repositioning surgery combined with orthodontic treatment in patients with temporomandibular disorder and facial asymmetry.@*Methods@#One patient who underwent disc repositioning surgery combined with orthodontic treatment for temporomandibular joint disorder and facial asymmetry was reported. Preoperatively, the patient had a skewed shape of the opening, mild pressure pain in the right preauricular region with left mandibular deviation, and a mismatch between the width of the upper and lower dental arches. In the arthrosurgery department, bilateral temporomandibular disc replacement and anchorage were performed through a transauricular incision, and an auxiliary splint was worn to stabilize the jaw position for 6 months. In the orthopedic department, maxillary skeletal expansion was used in combination with the multiloop edgewise archwire technique to reconstruct the occlusion after 16 months of orthodontic treatment.@*Results@#The deviation was corrected by wearing an occlusal splint for six months after joint repositioning and anchoring; moreover, the pain symptoms disappeared, and the cone beam CT examination showed that the bilateral temporomandibular joint space was uniformly enlarged, the lower alveolar ridge midline deviated to the right, the posterior regions of the teeth were bilaterally inverted, and the anterior region and the posterior region of the left side were open. The orthodontic treatment matched the width of the upper and lower dental arches and established the cuspal molar neutrality relationship and the normal overjet coverage of the anterior teeth; additionally, the mandibular position was not obviously skewed. A review of the results of the related literature shows that abnormal occlusal relationships, such as mismatched arch width and skewed occlusal plane, can cause adaptive mandibular deviation, which can lead to the occurrence of TMD. Temporomandibular joint disc anchorage with splint treatment can effectively improve maxillofacial deformity in young TMD patients. After the establishment of a stable, physiologically functional disc-condylar relationship, orthodontic treatment is required to remove the interfering factors to rebuild the occlusion, and long-term postoperative review and follow-up are needed.@*Conclusion@#In patients with TMD and mandibular accommodative deviation due to occlusal anomalies, establishing a normal disc-condylar relationship and eliminating occlusal interference through disc repositioning surgery combined with orthodontic treatment can effectively improve facial shape and establish a stable jaw position.
