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

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.

Anatomical Conditions in Simultaneous Orthognathic Surgery and Structural Rhinoplasty. A Clinical Series / Condiciones Anatómicas en Cirugía Ortognática y Rinoplastia Estructural Simultanea. Una Seria Clínica

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.

Análise comparativa entre a influência da amamentação e hábitos bucais deletérios no crescimento craniofacial / Comparative analysis between the influence of breastfeeding and deleterial oral habits on craniofacial growth

A adoção da chupeta e mamadeira pelos pais podem trazer problemas no desenvolvimento craniofacial da criança. A sucção digital é outro fator influenciador da má formação da face, este pode ser antecedido pela mamadeira e chupeta. O conhecimento sobre o desenvolvimento facial correto ajuda no reconhecimento de desvios da normalidade. Foi realizada uma revisão da literatura a fim de analisar e comparar os efeitos no crescimento facial entre os hábitos deletérios e a amamentação fisiológica. Muitos registros de malformações causadas por hábitos deletérios foram encontrados. Conclui-se que a amamentação natural ainda é a melhor forma de alimentação para crianças, e nenhuma outra opção será melhor que a fisiológica, sendo aconselhável evitar o uso dos demais(AU)

The adoption of pacifiers and bottles by parents can bring problems in the child's craniofacial development. Finger sucking is another factor influencing the malformation of the face, which can be preceded by the bottle and pacifier. Knowledge about correct facial development helps in recognizing deviations from normality. A literature review was carried out in order to analyze and compare the effects on facial growth between harmful habits and physiological breastfeeding. Many records of malformations caused by deleterious habits were found. It is concluded that natural breastfeeding is still the best form of feeding for children, and no other option will be better than the physiological one, being advisable to avoid the use of the others(AU)

Pesquisa de novos pontos craniométricos para aumento da precisão em reconstrução facial forense / Ressearch of new craniometric points for more accurate facial reconstruction

A estimativa de aparência da face de uma pessoa, partindo de um crânio seco, é chamada de Reconstrução Facial Forense (RFF). Pode ser realizada de maneira digital ou manual, a partir da marcação de pontos cranianos, que possuem diferentes médias de espessura de tecido mole sobreposto. Nas reconstruções digitais o uso de tomografias computadorizadas de feixe cônico (TCFC), que nos permite obter o volume de pacientes sentados, possibilitou um avanço significativo na mensuração das médias de volume dos tecidos moles faciais. Foi desenvolvido um protocolo para medições de tecidos moles a partir de 32 pontos craniométricos (10 sagitais e 11 bilaterais). Este trabalho propõe a inserção de cinco novos pontos cranianos ao protocolo, com medidas a partir dos pontos Mentual (Ml), Supra Canino (sC), Fronto-zigomático (Fz), Ptério (Pt) e Posterior do Ramo Mandibular (prM), com o intuito de aumentar a acurácia das reconstruções. As TCFC foram manipuladas no software Horus® (LGPL 3.0) e mensuradas conforme protocolo adaptado de Beaini et al. (1), obtidas as espessuras de tecido mole a partir dos pontos craniométricos propostos. Foram estudadas 100 TCFC de brasileiros adultos (maiores de 18 anos) que disponibilizaram seus exames para utilização em pesquisas de maneira anônima e que compõe um banco de dados já estruturado e utilizado em pesquisas anteriores. Esse banco de dados contém exames de 50 indivíduos do sexo feminino e 50 do sexo masculino, separados em grupos por sexo e idade. Estatisticamente, foram aplicados testes de normalidade e a diferença entre cada grupo foi testada para obtenção das espessuras médias referentes a cada ponto craniano. Para o ponto Fz, as médias de espessura de tecidos moles foram de 4.56mm para mulheres e 5.14mm para homens. Para o ponto Ml, as médias de ETMF foram de 12.88mm para mulheres e 14.74mm para homens. No ponto prM, as médias de ETMF foram de 18.30mm para homens e 19.69mm para mulheres. No ponto Pt, as médias de ETMF foram de 11.01mm para mulheres e 13.09mm para homens. No ponto sC, as médias de ETMF foram de 10.99mm para mulheres e 12.71mm para homens. A divisão de ETMFs por sexo é justificada, concordando com parcela significativa da literatura, uma vez que quatro 10 dos cinco pontos estudados apresentaram diferenças estatísticas significativas, com as espessuras de indivíduos do sexo masculino sendo maiores que de indivíduos do sexo feminino.

Aplicação do ultrassom microfocado no rejuvenescimento facial: uma revisão da literatura / Application of microfocused ultrasound in facial rejuvenation: a literature review

Introdução: O aumento da expectativa média de vida leva a população a buscar, com maior frequência, tratamentos estéticos que visem o rejuvenescimento da face e do pescoço. O Ultrassom microfocado (MFU) é descrito como uma opção de tratamento não-invasiva para a flacidez facial e o envelhecimento. Objetivo: Revisar a literatura científica quanto ao uso do MFU no processo de rejuvenescimento facial e correção da flacidez da pele. Metodologia: Trata-se de uma revisão narrativa da literatura, baseada na pesquisa de artigos científicos nas bases de dados PubMed e Biblioteca Virtual em Saúde realizada durante o mês de março de 2022, através da seguinte estratégia de busca: "Microfocused Ultrasound AND Facial Rejuvenation AND Skin Laxity Treatment". Um total de 19 manuscritos foram incluídos em síntese qualitativa. Desenvolvimento: O MFU pode ser aplicado no tecido subcutâneo, produzindo pequenos pontos de coagulação térmica dentro da camada reticular média a profunda da derme e subderme. A aplicação de calor nesses discretos pontos de coagulação térmica faz com que haja neossíntese de colágeno e consequente enrijecimento da pele. Estudos recentes evidenciaramresultados promissores quanto a aplicação do MFU em regiões de sulco nasolabial, linha da mandíbula, sobrancelhas, região infraorbital, palpebra inferior e ligamentos de retenção zigomático-bucais. Considerações finais: O MFU tem se mostrado uma técnica segura, sendo considerado eficaz, não-invasiva, bem tolerada pelos pacientes e viável para a prática clínica médica e odontológica.

Introduction: The increase in average life expectancy leads the population to seek, with greater frequency, aesthetic treatments aimed at rejuvenating the face and neck. Microfocused ultrasound (MFU) is described as a non-invasive treatment option for facial sagging and aging. Objective: To review the scientific literature regarding the use of MFU in the process of facial rejuvenation and correction of sagging skin. Methodology: This is a narrative review of the literature, based on the search for scientific articles in the PubMed and Virtual Health Library databases carried out during the month of March 2022, using the following search strategy: "Microfocused Ultrasound AND Facial Rejuvenation AND Skin Laxity Treatment". A total of 19 manuscripts were included in a qualitative synthesis. Development: MFU can be applied to the subcutaneous tissue, producing small points of thermal coagulation within the middle to deep reticular layer of the dermis and subdermis. The application of heat to these discrete points of thermal coagulation causes collagen neosynthesis and consequent skin tightening. Recent studies have shown promising results regarding the application of MFU in regions of the nasolabial sulcus, jaw line, eyebrows, infraorbital region, lower eyelid and zygomatic-buccal retention ligaments. Final considerations: MFU has been shown to be a safe technique, being considered effective, non-invasive, well tolerated by patients and viable for clinical medical and dental practice.

Etiology, diagnosis and treatment strategy of dental therapy-related subcutaneous emphysema / 中华口腔医学杂志

Subcutaneous emphysema is the local tissue swelling caused by the gas entering the subcutaneous tissue through the tissue gap. Although subcutaneous emphysema is usually a nonfatal and self-limited disease, in severe cases, the gas may spread to the neck, mediastinum and chest, resulting in mediastinal emphysema and other serious complications. This article reviews the etiology, pathogenesis, clinical manifestations, diagnosis, differential diagnosis of subcutaneous emphysema related to dental therapy,and operations that may cause subcutaneous emphysema in stomatology department,as well as the treatment and prognosis of subcutaneous emphysema, with a view to providing some references for dentists.

A case of Rubinstein-Taybi syndrome caused by a variant of EP300 gene / 中华医学遗传学杂志

OBJECTIVE@#To explore the clinical characteristics and genetic etiology of a child with Rubinstein-Taybi syndrome (RSTS).@*METHODS@#A child who was admitted to the Children's Hospital of Soochow University on October 3, 2021 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and his parents were collected. The child was subjected to whole exome sequencing (WES), and candidate variant was verified by Sanger sequencing of his family members and bioinformatic analysis.@*RESULTS@#The patient, a 9-year-and-４-month-old boy, had manifested unique facies, microcephaly, broad toes, growth retardation, and intellectual impairment. WES revealed that he has harbored a heterozygous c.3604G>T (p.E1202*) variant in exon 20 of the EP300 gene. Sanger sequencing confirmed that neither of his parents has carried the same variant. The variant was not found in the Shenzhou Genome data Cloud, ExAC, 1000 Genomes and gnomAD databases．Analysis with SIFT, PolyPhen-2 and CADD online software has predicted the variant to be harmful. Based on the guidelines formulated by the American College of Medical Genetics and Genomics, the variant was rated as pathogenic (PVS1＋PS2＋PM2_Supporting) .@*CONCLUSION@#The heterozygous c.3604G>T variant of the EP300 gene probably underlay the RSTS type 2 in this child. Above finding has also expanded the variation spectrum of the EP300 gene.

Transconjunctival lower eyelid blepharoplasty with "super released" orbital fat in correction of tear trough and palpebromalar groove depression / 中国修复重建外科杂志

OBJECTIVE@#To investigate effectiveness of transconjunctival lower eyelid blepharoplasty with "super released" orbital fat in correction of lower eyelid pouch protrusion and tear trough and palpebromalar groove depression.@*METHODS@#A clinical data of 82 patients (164 sides) with lower eyelid pouch protrusion and tear trough and palpebromalar groove depression, who met the selection criteria between September 2021 and May 2022, was retrospectively analyzed. Of the included patients, 3 were males and 79 were females, with an average age of 34.5 years (range, 22-46 years). All patients had varying degrees of eyelid pouch protrusion and tear trough and palpebromalar groove depression. The deformities were graded by the Barton grading system as gradeⅠ in 64 sides, grade Ⅱ in 72 sides, and grade Ⅲ in 28 sides. The orbital fat transpositions were performed through the lower eyelid conjunctival approach. The membrane surrounding the orbital fat was completely released, allowing the orbital fat to fully herniate until the herniated orbital fat did not retract significantly in a resting and relaxed state, which is regarded as the "super released" standard. The released fat strip was spread into the anterior zygomatic space and the anterior maxillary space, and percutaneous fixed to the middle face. The suture that penetrates the skin was externally fixed by adhesive tape pasting without knotted.@*RESULTS@#There were 3 sides with chemosis after operation, 1 side with facial skin numbness, 1 side with mild lower eyelid retraction at the early stage after operation, and 5 sides with slight pouch residue. No hematoma, infection, or diplopia occurred. All patients were followed up 4-8 months, with an average of 6.2 months. The eyelid pouch protrusion, tear trough, and palpebromalar groove depression were significantly corrected. At last follow-up, the deformity was graded by Barton grading system as grade 0 in 158 sides and grade Ⅰ in 6 sides, with a significant difference compared to the preoperative score ( P<0.001). Patient's self-evaluation satisfaction reached very satisfied in 67 cases (81.7%), satisfied in 10 cases (12.2%), generally satisfied in 4 cases (4.8%), and dissatisfied in 1 case (1.2%).@*CONCLUSION@#The "super released" orbital fat can effectively prevent the retraction of orbital fat, reduce the probability of residual or recurrence of eyelid pouches, and improve the correction effect.

Panscleritis After Blunt Ocular Trauma in A Child with Epididymitis / 中国医学科学杂志(英文版)

We reported an 8-year-old boy with panscleritis in left eye and right epididymitis after falling on the ground. Etiologic diagnosis played a key role in this case. Systemic examinations ruled out systemic autoimmune diseases, tumors, and infections as the cause of scleritis and suggested that the disease was caused by a local delayed-type hypersensitivity (DTH) induced by ocular trauma and was non-infectious. Still, the right epididymitis was infectious. Both conditions were treated successfully using steroids and antibiotics, respectively. Thus, early etiologic diagnosis and reasonable treatment are crucial to prevent visual loss.

Blue Nevus Hidden within the Nevus of Ota / 中国医学科学杂志(英文版)

A 3-year-old boy presented with bluish patch and scattered blue spots on the left side of his face. After several sessions of laser treatment, the azury patch in the periorbital area became even darker. Histopathology showed many bipolar, pigment-laden dendritic cells scattered in the papillary and upper reticular dermis. Immunohistochemically, these cells were positive for S100, SOX-10, melan-A, P16, and HMB-45. The positive rate of Ki-67 was less than 5%. Finally, the lesion was diagnosed with nevus of Ota concurrent with common blue nevus. Therefore, for cases of the nevus of Ota with poor response to laser treatment, the possible coexisting diseases should be suspected.

Inventory of parenting systems and styles: a measure for early childhood / Inventário de sistemas e estilos parentais: uma medida para a primeira infância / Inventario de estilos y sistemas de crianza: una medida para la primera infância

The Component Model of Parenting (CMP), from an evolutionary perspective, proposes a phylogenetically evolved repertoire of six systems (body contact, body stimulation, face-to-face exchange, object stimulation, and primary care) and two parenting styles (distal and proximal) by combining some of these systems. We developed the Inventory of Parenting Systems and Styles (ISEP) and applied it to hospitals and schools to analyze its psychometric properties. The parenting measure analysis we propose evolved 70 primary caregivers of young children with a mean age of 22.44 months. ISEP consists of 26 daily situations and assesses the most common parenting practices caregivers adopted in each one of them. Besides, we created a Coding Guide to Parenting Practice. It enabled us to classify each response according to the CMP systems. We found a variance of 84.67% and 95.55% in codification agreement between expert judges and a significant intraclass correlation coefficient for all parenting systems, which discloses validity evidence on the response process of the inventory. Our analyses indicated the occurrence of all parental systems, with a prevalence of narrative envelope and body stimulation. Cluster analysis revealed two clusters, one formed by proximal style and another by distal style, in accordance with the interactions of the system, representing a validity of evidence based on the internal structure of the instrument. ISEP provides reasonable measures for research and professional practice in Psychology. Further research with more extensive and diverse samples is necessary to refine the instrument and, especially its guide.(AU)

O Modelo de Componentes da Parentalidade (MCP) da perspectiva evolucionista propõe seis sistemas - contato corporal, estimulação corporal, contato face a face, estimulação por objeto, envelope narrativo e cuidado primário - universais e filogeneticamente evoluídos, e dois estilos parentais - distal e proximal - oriundos da combinação de alguns desses sistemas. Para analisar propriedades psicométricas de uma medida de parentalidade, o Inventário de Sistemas e Estilos Parentais (ISEP) foi aplicado em contexto escolar e hospitalar, em 70 cuidadores primários de crianças com idade média de 24,44 meses. O ISEP, construído para este estudo, apresenta 26 situações cotidianas e solicita que cuidadores indiquem a prática parental mais comumente adotada em cada uma delas, e cada resposta foi classificada em um dos sistemas do MCP por um Guia de Codificação de Práticas Parentais. A concordância entre juízes com a codificação variou entre 84,67% e 95,55%, e os coeficientes de correlação intraclasse foram significativos para todos os sistemas de parentalidade, representando uma evidência de validade por processo de resposta do inventário. As análises indicaram a ocorrência de todos os sistemas parentais, com predominância de envelope narrativo e estimulação corporal. Uma análise de cluster formou dois conglomerados, um derivando o estilo proximal e outro o estilo distal, de acordo com a interação entre os sistemas, constituindo uma evidência de validade baseada na estrutura interna do instrumento. O ISEP mostrou ser uma medida promissora para a pesquisa e a prática profissional em Psicologia. Outras pesquisas com amostras mais amplas e diversificadas são necessárias para refinamento do instrumento e do guia.(AU)

El Modelo Componencial del Parentaje (MCP), desde una perspectiva evolutiva, propone seis sistemas (contacto corporal, estimulación corporal, contacto cara a cara, estimulación con objetos, envoltura narrativa y atención primaria), universales y filogenéticamente evolucionados, así como dos estilos parentales (distal y proximal) que se originan combinando algunos de ellos. Para analizar las propiedades psicométricas de una medida parental, se aplicó el Inventario de Estilos y Sistemas de Crianza (ISEP), en el contexto escolar y hospitalario, a 70 cuidadores primarios de niños con una edad media de 24,44 meses. El ISEP fue construido para el presente estudio, presenta 26 situaciones cotidianas y crianza los cuidadores deben indicar la práctica parental más común adoptada en cada una de ellas. Una Guía de Codificación de Prácticas Parentales permite clasificar cada respuesta en uno de los sistemas del MCP. La concordancia entre los jueces con la codificación varió entre 84,67% y 95,55% y los coeficientes de inter-correlación en todos los sistemas parentales fueron significativos, evidenciando su validez por el proceso de respuesta al inventario. Los análisis indicaron la ocurrencia de todos los sistemas parentales, con predominio de envoltura narrativa y estimulación corporal. Un análisis de clusters formó dos conglomerados, derivando el estilo proximal y el estilo distal, según la interacción entre los sistemas, constituyendo evidencia de validez basada en la estructura interna del instrumento. El ISEP demostró ser una medida valida y fiable para la investigación y la práctica profesional en Psicología. Se necesita más investigación con muestras más grandes y diversificadas para perfeccionar el instrumento.(AU)

Torus mandibular e palatino predisponentes em um grupo familiar: fatores genéticos e ambientais, relato de uma série de casos / Mandibular and palatine torus predisposing in a family group: genetic and environmental factors, report of a series of cases / Torus mandibular y palatino predisponente en un grupo familiar: factores genéticos y ambientales, informe de una serie de casos

As exostoses mais conhecidas são o Torus palatino e mandibular, que se desenvolvem a partir do crescimento benigno da cortical óssea, localizadas respectivamente na linha média palatina e superfície lingual de caninos e pré-molares, podendo ser unilaterais ou bilaterais. Esse trabalho tem como objetivo o estudo de um grupo familiar que apresentaram o Torus como característica em comum, buscando confirmar a presença e prevalência das características clínicas multifatoriais listadas na literatura, possibilitando o diagnóstico da etiologia e assim traçando um plano de tratamento individual, se necessário. Como metodologia, foi realizada uma triagem com cada membro familiar na clínica Odontológica da Faculdade Sete Lagoas - FACSETE, descartando a participação no estudo os membros que não apresentaram o Torus. Os indivíduos que apresentaram indicação da remoção cirúrgica foram encaminhados para clínica de cirurgia da própria instituição. Concluímos, portanto, com este estudo que fatores genéticos e ambientais colaboram como fator etiológico mais predominantes para surgimento do Torus no grupo familiar estudado... (AU)

The best known exostosis are the palatine and mandibular Torus, which develop from the benign growth of the cortical bone, located respectively in the midpalatal line and lingual surface of canines and premolars, and maybe unilateral or bilateral. This work aims to study a family group that had Torus as a common feature, confirming the presence and prevalence of multifactorial clinical features listed in the literature, enabling the diagnosis of etiology and thus outlining an in dividual treatment plan, if necessary. As a methodology, a screening was performed by each family member at the Dental Clinic of Facul dade Sete Lagoas - FACSETE, discarding the participation in the study for members who did not present Torus. Individuals who indicated surgical removal were referred to the institution's own surgery clinic. Therefore, we conclude with this study that genetic and environmental factors collaborate as the most predominant etiological factor for the emergence of Torus in the studied family group... (AU)

Las exostosis más conocidas son el Torus palatino y el Torus mandibular, las cuales se desarrollan a partir del crecimiento benigno del hueso cortical y están ubicadas respectivamente en la línea medio palatina y en la cara lingual de los caninos y de los premolares que pueden ser unilaterales o bilaterales. Este proyecto tiene como objetivo el estudio de un grupo familiar que presentó en sus características comunes el Torus, buscando confirmar la presencia y el predominio de las características clínicas multifactoriales listadas en la literatura, lo que hizo posible el diagnóstico de la etiología y diseñar un plan de tratamiento individual, caso necesiten. Como la metodología fue hecho una selección con los miembros de la familia en la clínica odontologica de la Faculdade Sete Lagoas - FACSETE, quitando de los estudios las personas de la familia que no presentaron el Torus. Los individuos que presentaron indicación de extirpación quirúrgica fueron enviados a la clínica de cirugía de la escuela. Concluimos con este estudio que los factores genéticos y ambientales colaboraron como los factores etiológicos más predominantes para la aparición del Torus en la familia analizada... (AU)

Estabilização zigomática e retalho de avanço facial lateral em canino filhote / Zygomatic stabilization and lateral facial advancement flap in a puppy dog

O trauma é frequentemente relatado na rotina clínica de pequenos animais, podendo gerar fraturas de componentes ósseos e lesões de tecidos moles adjacentes. No presente trabalho, objetivou-se relatar o caso de um canino, macho, sem raça definida, de sete meses de idade, vítima de trauma craniomaxilofacial decorrente de mordedura, diagnosticado com fratura e deslocamento de osso zigomático, além de importante laceração de pele. O tratamento estabelecido baseou-se no debridamento da ferida, estabilização cirúrgica de arco zigomático com fios de Nylon e na sutura dos ferimentos de pele causados. Em um segundo tempo cirúrgico, foi realizada enucleação e recobrimento do defeito na órbita com malha cirúrgica de polipropileno, além de remoção de tecido exuberante e confecção de retalho subdérmico de avanço facial lateral para recobrimento do defeito cutâneo. A complicação evidenciada na primeira intervenção cirúrgica foi a deiscência das suturas de pele, enquanto no segundo tempo cirúrgico, não houve sinais de complicações. No pós-operatório, o paciente apresentou evolução clínica satisfatória, recebendo alta médica 21 dias após o segundo procedimento cirúrgico realizado. Tendo em vista a adequada evolução clínica, bem como os reduzidos efeitos colaterais, sugere-se que a conduta clínica e técnicas cirúrgicas adotadas para tratamento do paciente em questão foram efetivas.

Trauma is frequently reported in the small animal clinics, and can lead to fractures of cranial bone components and injuries to the adjacent soft tissues. In the present study, the objective was to report the case of a seven-month-old male mongrel dog, that had a craniomaxillofacial trauma resulting from a bite, characterized by zygomatic bone fracture and displacement, in addition to a major skin laceration. The stablished treatment was based on wound debridement, surgical stabilization of the zygomatic arch with nylon threads and in the suturing of skin wounds. In a second surgical procedure, enucleation was performed and a surgical polypropylene mesh was applied to cover the orbital defect, exuberant tissue was removed and a subdermal advancement flap was used to cover the skin defect. The complication observed in the first surgical intervention was dehiscence of the skin sutures, while in the second surgical procedure, there were no signs of complications. Postoperatively, the patient had a satisfactory clinical recovery, being discharged 21 days after the second surgical procedure. Considering the adequate clinical evolution and the reduced complications, it issuggestedthat the clinical conduct and surgical techniques adopted for the treatment of the patient in question were effective.

Correlation between vertical dimension of occlusion and different facial measurements among a sample of sudanese adults / Correlación entre la dimensión vertical de la oclusión y diferentes medidas faciales en una muestra de adultos sudaneses

Aim: This study aimed to evaluate the correlation between vertical dimension of occlusion (VDO) and various facial measurements in a sample of Sudanese adults. Material and Methods: A total of 113 dental students (33 males and 80 females) with a mean age of 21.7±1.26 years were enrolled in this study. Different facial measurements including (Eye-Mouth, Eye-Eye, Eye-Ear, and Ear Height) were compared with two different measurements of VDO: N-Gn (from the tip of the nose to the tip of the chin), and Sn-Me (from the base of the nose to the bottom of the chin). Pearson's correlation coefficient test was utilized for the correlation between the measured parameters. A p-value of less than 0.05 was considered significant for all analyses. Results: A significant positive correlation was shown between all measured facial distances and both measured VDO distances. Though, the strongest correlation was seen for the eye-mouth distance (r= 0.725, p<0.001), while the weakest was for ear height (r= 0.254, p= 0.007). A paired t-test revealed a significant longer N-Gn distance than Sn-Me distance. Also, it has been shown that there were no significant differences between right and left sides of the face. Conclusion: The distance measured from the outer canthus of the eye to the angle of the mouth can be used to predict Subnasale-Menton (Sn-Me) distance.

Objetivo: Este estudio tuvo como objetivo evaluar la correlación entre dimensión vertical oclusal (DVO) y varias medidas faciales en una muestra de adultos sudaneses. Material y Métodos: Un total de 113 estudiantes de odontología (33 hombres y 80 mujeres) con una edad media de 21,7 ± 1,26 años se inscribieron en este estudio. Se compararon diferentes medidas faciales que incluyen (ojo- boca, ojo-ojo, ojo-oído y altura de la oreja) con dos medidas diferentes de DVO: N-Gn (desde la punta de la nariz hasta la punta del mentón) y Sn -Yo (desde la base de la nariz hasta la parte inferior del mentón). Se utilizó la prueba del coeficiente de correlación de Pearson para la correlación entre los parámetros medidos. Un valor de p inferior a 0,05 se consideró significativo para todos los análisis. Resultados: Se mostró una correlación positiva significativa entre todas las distancias faciales medidas y ambas distancias DVO medidas. Sin embargo, la correlación más fuerte se observó para la distancia ojo-boca (r=0,725, p<0,001), mientras que la más débil fue para la altura de las orejas (r=0,254, p=0,007). Una prueba de t pareada reveló una distancia N-Gn significativamente más larga que la distancia subnasal-mentón. Además, se ha demostrado que no hubo diferencias significativas entre los lados derecho e izquierdo de la cara. Conclusión: La distancia medida desde el canto externo del ojo hasta el ángulo de la boca puede utilizarse para predecir la distancia subnasal-mentón.

Individual Identification in Facial Appearance Biometrics Based on Macroscopical Comparison / 法医学杂志

Individual identification is one of the research hotspots in the practice of forensic science, and the judgment is usually built on the comparison of the unique biological characteristics of the individual, such as fingerprints, iris and DNA. With the dramatic increase in the number of cases related to video image investigations, there is an increasing need for the technology to identify individuals based on the macroscopic comparison of facial appearance biometrics. At present, with the introduction of computer three-dimensional (3D) modeling and 3D superimposition comparison technology, considerable progress has been made in individual identification methods based on macroscopic comparison of facial appearance biometrics. This paper reviews individual facial appearance biometric methods based on macroscopical comparison, comprehensively analyzes the advantages and limitations of different methods, and puts forward recommendations and prospects for subsequent research.

Application of Artificial Intelligence in Recognition and Evaluation of Facial Paralysis / 中国医疗器械杂志

This paper reviews some recent studies on the recognition and evaluation of facial paralysis based on artificial intelligence. The research methods can be divided into two categories: facial paralysis evaluation based on artificial selection of patients' facial image eigenvalues and facial paralysis evaluation based on neural network and patients' facial images. The analysis shows that the method of manual selection of eigenvalues is suitable for small sample size, but the classification effect of adjacent ratings of facial paralysis needs to be further optimized. The neural network method can distinguish the neighboring grades of facial paralysis relatively well, but it has a higher requirement for sample size. Both of the two methods have good prospects. The features that are more closely related to the evaluation scale are selected manually, and the common development direction may be to extract the time-domain features, so as to achieve the purpose of improving the evaluation accuracy of facial paralysis.
