Caracterización clínico epidemiológica de los pacientes con alteraciones bucomaxilofaciales en la provincia Camagüey

Introducción: Las personas con una deformación facial comúnmente están expuestas a las críticas o presión, colocando al individuo en situaciones embarazosas. El uso de prótesis es una solución eficiente a las deformidades faciales ya que evita complicaciones quirúrgicas y produce un buen resultado estético cuando no es posible la reconstrucción quirúrgica o se prefiere por el paciente. Objetivo: Caracterizar clínica y epidemiológicamente los pacientes con alteraciones bucomaxilofaciales en la provincia Camagüey. Métodos: Se realizó un estudio descriptivo de serie de casos en el periodo comprendido entre marzo y diciembre de 2022. Se tomó la información existente en las bases de datos y en los trabajos de terminación de la especialidad de Prótesis Estomatológica, realizados entre los años 2001 al 2019. Se utilizó para el análisis de la información, estadística descriptiva para distribución de frecuencias y los resultados finales se incluyeron en tablas. Resultados: La mayoría de los casos fueron pacientes masculinos, de edades entre 46 y 60; los defectos más frecuentes encontrados fueron los oculares. En cuanto al sexo fue evidente una mayor necesidad de prótesis bucomaxilofacial en los hombres y dentro de estas las prótesis oculares. Entre las principales causas de pérdida de estructuras se encontraron los traumatismos y las lesiones oncológicas. Conclusiones: Los defectos bucomaxilofaciales repercuten de forma negativa en la calidad de vida de quienes los padecen; las causas que generan los mismos, las regiones donde más se presentan, el sexo y la edad en que aparecen son elementos a tener en cuenta para un correcta prevención de dichas lesiones pero también permiten establecer pautas de trabajo encaminadas a brindar una atención multidisciplinaria para su rehabilitación protésica e integral.

Introduction: People with a facial deformity are commonly exposed to criticism or pressure, placing the individual in embarrassing situations. The use of prostheses is an efficient solution to facial deformities since it avoids surgical complications and produces a good aesthetic result when surgical reconstruction is not possible or is preferred by the patient. Objective: To characterize clinically and epidemiologically patients with oral and maxillofacial alterations in Camagüey province. Methods: A case report type study was carried out taking the results of the databases, completion works of the Dentistry Prosthesis specialty between the years 2001 and 2019. The study was carried out in the period between March and December 2022. The results were reflected in tables using descriptive statistics for them. Results: Most of the cases were male patients, aged between 46 and 60; the most frequent defects found were the ocular ones. Regarding gender, a greater need for oral and maxillofacial prostheses was evident in men, and within these, ocular prostheses. Among the main causes of loss of structures were traumatisms and oncological lesions. Conclusions: Oral and maxillofacial defects have a negative impact on the quality of life of those who suffer from them; the causes that generate them, the regions where they occur most, the sex and the age in which they appear are elements to take into account for a correct prevention of said injuries but also allow the establishment of work guidelines aimed at providing multidisciplinary care for their prosthetic and integral rehabilitation.

Relationship between Oral Parafunctions and Signs and Symptoms of Craniomandibular Dysfunction in Children with Cleft Lip and Palate / Relação Entre Parafunções Orais e Sinais e Sintomas de Disfunção Craniomandibular em Crianças com Fissura Labiopalatina

The aim of this study was to evaluate the association of oral parafunctions with the presence of signs and symptoms of craniomandibular disorder in children with cleft lip and palate (CLP). A cross-sectional study was performed in which one hundred and eighty-eight children with CLP and absence of associated syndromes or malformations were investigated. During clinical examination, the presence of wear facets and dental occlusion were observed and palpation was performed in the temporomandibular joint region (TMJ) and orofacial musculature . The children and their guardians were interviewed regarding the presence of oral parafunctional habits (bruxism, the act of biting the lips and/or cheeks, nail biting, sucking of fingers and pacifiers) and signs and symptoms of craniomandibular dysfunction (headache, ear and/or neckache, tiredness or crack in the TMJ during mouth opening and chewing movements). The data were analyzed by means of absolute and relative frequency measurements, and bivariate analysis using Pearson's chi-square test and likelihood ratio test were performed, considering the significance level of 5%. A higher prevalence of cleft lip and palate type (76.0%) and the presence of malocclusion (61.7%) was observed, highlighting the anterior crossbite (58.7%) and midline deviation (48.9%). There was a higher occurrence of teeth grinding (40.4%), onychophagy (28.7%) and biting lips and/or cheeks (28.7%). Onychophagia was associated with headache (p <0.05) and with pain or cracking during mouth opening (p <0.05). It was concluded that parafunctional oral habits may be associated with signs and symptoms of craniomandibular disorder in children with cleft lip and palate.

O objetivo do estudo foi avaliar a associação de parafunções orais com sinais e sintomas da disfunção craniomandibular em crianças com fissuras labiopalatinas (FLP). Um estudo transversal foi realizado, no qual cento e oitenta e oito crianças com FLP e ausência de síndromes ou malformações associadas, foram investigadas. Durante exame clínico, a presença de facetas de desgaste e a oclusão dentária foram observadas e foi realizada a palpação na região da articulação temporomandibular (ATM) e musculatura orofacial. As crianças e seus responsáveis foram entrevistados com relação à presença de hábitos orais parafuncionais (bruxismo, ato de morder os lábios e/ou bochechas, onicofagia, sucção de dedos e de chupeta) e sinais e sintomas de disfunção craniomandibular (cefaléia, ouvido, dor, cansaço ou estalo na ATM durante movimentos de abertura bucal e de mastigação). Os dados foram analisados por meio de medidas de frequência absoluta e relativa e a análise bivariada foi realizada por meio dos testes do Qui-quadrado de Pearson (χ2) e a Razão de verossimilhança, considerando o nível de significância de 5%. Uma maior prevalência das fissuras envolvendo lábio e palato (76,0%) e presença de maloclusão (61,7%) foi observada, com destaque para mordida cruzada anterior (58,7%) e desvio de linha média (48,9%). Houve uma maior ocorrência do ato de ranger os dentes (40,4%), da onicofagia (28,7%) e do hábito de morder lábios e/ou bochechas (28,7%). A onicofagia foi associada à cefaléia (p<0,05) e à dor ou estalo durante abertura bucal (p<0,05). Conclui-se que hábitos orais parafuncionais podem estar associados a presença de sinais e sintomas da disfunção craniomandibular em crianças com FLP.

Remoção de pré-maxila em paciente com fissura labiopalatina: relato de caso / Removal of the premaxilla in patient with cleft lip and palate: case report

Diversas anomalias craniofaciais acometem os seres humanos, dentre estas podem ser citadas as fissuras labiopalatinas. Ocorrem devido à mal formações congênitas e comprometem o desenvolvimento orofacial e maxilo-mandibular, gerando complicações estéticas e funcionais. O momento para abordagem cirúrgica em pacientes com deformidade deste tipo é crucial para atingir o melhor resultado. Entretanto, muitos deles não procuram atendimento ou não tem acesso aos centros especializados. A pré-maxila em portadores de fissura labiopalatina transforame bilateral, não submetidos a tratamento cirúrgico na infância, é comumente protruída, impedindo o desenvolvimento e função adequada da musculatura perioral/ Ainda, pode causar dificuldades alimentares,de fonação e, principalmente, estético. O objetivo do presente trabalho é relatar o caso de uma paciente acompanhada no serviço de cirurgia bucomaxilofacial OSID/UFBA, portadora de fissura labiopalatina, submetida à remoção de pré-maxila em idade adulta. O fechamento da fenda palatina não foi possível devido a idade da paciente e o grau de desenvolvimento do palato, tendo indicado tratamento com uso de prótese obturadora. Considera-se que quanto mais precoce e associado a uma boa técnica cirúrgica forem realizadas as intervenções primárias, menores serão as sequelas. Consequentemente, os resultados estéticos e funcionais serão mais prováveis, sendo desnecessária a remoção cirúrgica da pre-maxila(AU)

Several craniofacial anomalies affect humans and, among these, it can be cited the cleft lip and palate. These occur due to congenital malformations and compromise the orofacial and maxillo-mandibular development, causing aesthetic and functional complications. The moment of the surgical approach in patients with this type of deformities is crucial to achieve the best outcome, however, many of them do not seek care or have no access to specialized centers. The premaxilla in carries of bilateral cleft lip and palate when they are not submitted to a surgical treatment in childhood, is commonly protruding, impeding the development and function of the perioral musculature, besides difficult feeding, phonation and mainly aesthetic. The aim of this article is to report the case of a patient accompained with the Bucomaxillofacial Surgery Service from OSID / UFBA, with cleft lip and palate, submitted to pre-maxilla removal, in adulthood. The cleft palate closure was not possible due to the age of the patient and degree of development of the palate, indicating treatment with obturator prosthesis. It is considered that, the sooner and associated with a good surgical technique, primary interventions are performed, the fewer the sequelae and consequently the aesthetic and functional results, where, in most cases, surgical removal of the premaxilla will be unnecessary(AU)

Introduction: dentofacial deformities are seen as extreme cases of facial typology variation, characterized by major changes in occlusion associated with functional modifications. It requires an ortho-surgical treatment, in which the bone bases are reconstructed through orthognathic surgery. Treatment and monitoring are required after surgery with a Speech-language Pathologist (SLP) in order to assist patients in the recognition of their new faces and in the adjustments of orofacial functional patterns, avoiding negative interferences. Purpose: to report an orthognathic surgery clinical case in a 10-year longitudinal follow-up through the analysis of the SLP assessments. Case report: a prognathous 26-year-old woman with Class III craniofacial deformity, presenting aesthetic and chewing complaints with indication for orthognathic surgery. Five SLP ́s assessments were conducted, as follows: the first one, in the preoperative stage; the second, 19 days after the surgery; the third, after three months of SLP rehabilitation; the fourth, after four months of follow-up as maintenance of the results obtained; and the fifth, ten years after the surgical intervention. In the preoperative assessment, changes were recorded in the myofunctional pattern related to chewing, swallowing, speech and breathing functions. Improvements in the lip, cheek and masseter muscles were reported after SLP therapy, as well as in tongue posture and mandibular range of motion. After 10 years, favorable changes were observed in breathing pattern and tongue posture at rest, organization and stability of speech, articulation, and swallowing patterns, as well as in the patient's self-esteem. Final considerations: the SLP approach associated with orthognathic surgery and orthodontics procedure achieved evolutions and proved to be effective, leading this patient to satisfactory new adjustments of the myofunctional pattern.

Common characteristics of temporomandibular joint surgery and orthognathic surgery / 中华口腔医学杂志

Orthognathic surgery and temporomandibular joint (TMJ) surgery are two relatively independent disciplines in oral and maxillofacial surgery. Dentofacial deformities and TMJ diseases commonly coexist. The diagnosis and treatment of the diseases with coexisting dentofacial deformities and TMJ disorders is complex. Thus it is very important to comprehensively understand the common characteristics of orthognathic and TMJ surgery, which places a greater demand on oral and maxillofacial surgeons. The present work focuses on our thinking on common characteristics of TMJ and orthognathic surgery based on the managements of these diseases.

Interference of dentofacial deformities in the acoustic characteristics of speech sounds / Interferência das deformidades dentofaciais nas características acústicas dos sons da fala

ABSTRACT Purpose: to verify speech characteristics regarding the production of fricative sounds in people with dentofacial deformities (DFD), through acoustic analysis, evaluating possible interferences of the variation of the osseous bases in the articulation of speech. Methods: fifteen adults of both genders, aged between 17 and 42, participated in the study. They were distributed in three groups: GII (n = 5) Skeletal Class II, GIII (n = 5) Skeletal Class III, and CG (n = 5) without DFD. All of them had their voices recorded, with key words containing the fricative sounds of Brazilian Portuguese (BP), and acoustically analyzed; the parameters: duration, intensity, and formants F1, F2. The Mann-Whitney test was used to compare the groups. Results: there were differences (p <0.05) when comparing GII and GIII with CG. For the variable duration GIII obtained higher value in the fricative sound /z/ (r = 0.016, p <0.05). The variable intensity was higher for GII in /z/ (r = 0.028, p <0.05), and higher for GIII in /f/ (r = 0.028, p <0.05), /v/ (r = 0.028, p<0.05) and /ʃ/ (r = 0.036, p <0.05). For the variable F1, GII obtained a higher value for the syllable /za/ (r = 0.047, p <0.05). In the variable F2, GII obtained the lowest value in the syllable /ʒa/ (r = 0.047, p <0.05). Conclusion: the disharmony of the maxillomandibular osseous bases results in interference in speech acoustic characteristics regarding fricative sounds.

RESUMO Objetivo: verificar as características da fala quanto a produção dos sons fricativos em indivíduos com deformidades dentofaciais (DDF), por meio da análise acústica, analisando possíveis interferências da variação das bases ósseas na articulação da fala. Métodos: participaram 15 indivíduos adultos, ambos os sexos, com idade entre 17 a 42 anos. Distribuídos em 3 grupos: GII (n=5) Classe II esquelética, GIII (n=5) Classe III esquelética e GC (n=5) sem (DDF). Todos tiveram suas vozes gravadas, com "palavras-chave" contendo os sons fricativos do português brasileiro (PB), e analisadas acusticamente, os parâmetros: duração, intensidade, e formantes F1, F2. Para a comparação entre os grupos foi utilizado o Teste de Mann-Whitney. Resultados: houve diferenças (p<0,05) ao comparar GII e GIII com GC. Para a variável duração GIII obteve valor maior no som fricativo /z/ (r=0,016; p<0,05). A variável intensidade foi maior para o GII em /z/ (r=0,028; p<0,05), e maior para o GIII em /f/ (r=0,028; p<0,05), /v/ (r=0,028; p<0,05) e /ʃ/ (r=0,036; p<0,05). Para a variável F1, GII obteve valor maior para a sílaba /za/ (r=0,047; p<0,05). Na variável F2 o GII obteve valor mais baixo na sílaba /ʒa/ (r=0,047; p<0,05). Conclusão: a desarmonia das bases ósseas maxilomandibulares resulta em interferência nas características acústicas da fala quanto aos sons fricativos.

Objetivo: Avaliar a qualidade de vida relacionada à saúde e a capacidade para o trabalho de pessoas com deformidades faciais. Método: Estudo misto de abordagem qualitativa e quantitativa. Entrevistas semiestruturadas sobre qualidade de vida em saúde e implicações no trabalho foram realizadas com 16 pessoas com deformidades faciais, oito congênitas e oito adquiridas, procedentes de serviços de atenção especializada de Salvador, Bahia. Aplicaram-se os questionários Índice de Capacidade para o Trabalho (ICT) e 36-Item Short-Form Health Survey. Resultados: A análise temática permitiu identificar duas categorias associadas às deformidades faciais: relações interpessoais e capacidade para o trabalho; e qualidade de vida e acesso a tratamento. Indivíduos com deformidades faciais adquiridas apresentaram menor escolaridade, renda e índices mais baixos nos indicadores de qualidade de vida e ICT, quando comparados aos do grupo com deformidades congênitas. Todos com deformidades congênitas receberam algum tipo de reabilitação e apresentaram menor comprometimento das relações sociais. Conclusões: Pessoas com deformidades faciais adquiridas apresentam maior comprometimento da sua capacidade para o trabalho e qualidade de vida do que aquelas com deformidades faciais congênitas. A reabilitação precoce das anormalidades congênitas parece exercer papel importante na melhora dos índices de ICT e de qualidade de vida em saúde

Background: The face plays a central role in interpersonal relationships. Individuals with congenital or acquired facial deformities might experience difficulties with interpersonal relationships. Treatment should seek to improve their quality of life and work ability. Objective: To analyze the health-related quality of life and work ability of individuals with facial deformities. Method: Study with mixed, quantitative and qualitative methods. We conducted semi-structured interviews on health-related quality of life and its implications for work with 16 individuals with facial deformities, eight cases of congenital and eight of acquired deformities, cared at specialized services in Salvador, Bahia, Brazil. The Work Ability Index (WAI) and 36-Item Short-Form Health Survey were administered. Results: Thematic analysis led us to detect two categories of themes associated with facial deformities: interpersonal relationships and work ability; and quality of life and access to treatment. The participants with acquired facial deformities exhibited lower educational level and income, and lower quality of life and WAI scores compared to the ones with congenital deformities. All the participants with congenital deformities had received some form of rehabilitation and their social relationships were less impaired. Conclusions: Individuals with acquired facial deformities exhibited poorer work ability and quality of life compared to the ones with congenital deformities. Early rehabilitation of congenital deformities seems to considerably improve work ability and health-related quality of life

Resumen Introducción: las hendiduras orofaciales son las malformaciones congénitas de cabeza y cuello más frecuentes en el mundo, con gran importancia epidemiológica por su alto impacto sobre la calidad de vida de la población. Este impacto está dado en gran parte por la presencia de complicaciones postquirúrgicas, por lo que es importante conocerlas, con el fin de aplicar estrategias de prevención o de corrección temprana. Objetivo: identificar las principales complicaciones posquirúrgicas de la cirugía correctiva de labio hendido, paladar hendido o ambos, en un hospital de tercer nivel en Bucaramanga, Santander, Colombia. Materiales y métodos: estudio observacional descriptivo de corte transversal. Se obtuvo la información de los registros de historias clínicas médicas, de pacientes cuya intervención quirúrgica fue realizada durante el período de enero de 2013 a diciembre de 2016. Resultados: se obtuvieron registros de 55 pacientes. La presentación conjunta de labio y paladar hendido fue la anomalía craneoencefálica más frecuente (70,9%). La complicación más frecuente fue la fístula oronasal (23,9% de pacientes con compromiso del paladar), seguida por la dehiscencia de la herida quirúrgica (3,6%). Se encontró un mayor porcentaje de complicaciones postquirúrgicas en el sexo masculino. Conclusión: la complicación postquirúrgica de corrección de labio y/o paladar hendido más frecuente encontrada en la muestra fue la fístula oronasal. MÉD.UIS. 2018;31(2):25-32.

Abstract Introduction: the orofacial clefts are the most frequent congenital malformations of the head and neck in the world, with great epidemiological importance for their impact on the quality of life of the population. This impact is largely due to the presence of postsurgical complications, which is why it is important to know them, in order to apply prevention strategies or early correction. Objective: to identify the main complications following surgical treatment of cleft lip, cleft palate or both, in a third level hospital in Bucaramanga, Santander, Colombia. Materials and methods: descriptive cross-sectional study. The information was obtained from the medical records of patients whose surgical intervention was performed during the period from january 2013 to december 2016. Results: records of 55 patients were obtained. The joint presentation of cleft lip and palate was the most frequent craniofacial anomaly (70.9%). The most frequent complication was oronasal fistula (23.9% of patients with compromised palate), followed by dehiscence of the surgical wound (3.6%). A higher percentage of postoperative complications was found in the male sex. Conclusion: the postoperative complication of lip and/or cleft palate correction most frequently found in the sample was the oronasal fistula. MÉD.UIS. 2018;31(2):25-32.

Staged Nasal Reconstruction Using a Forehead Flap and Rib Bone and Cartilage Graft in a Binder Syndrome Patient: A Case Report

Binder syndrome is a rare maxillofacial abnormality. Yet, once presented, it often needs to be addressed surgically. To suit this purpose, various surgical techniques have been developed. This paper is a case report of a staged nasal reconstruction in a Binder syndrome patient using rib bone and cartilage graft and forehead flap. At the same time, preoperative and postoperative anthropomorphometric measurements were compared to assess the efficiency of the proposed surgical technique.

Clinical characteristics and genetic analysis of neonatal asymmetric crying facies / 中国新生儿科杂志

Objective To study the clinical and genetic characteristics of neonatal asymmetric crying facies (ACF).Method From January 2007 to December 2016,clinical data were retrospectivelyreviewed in patients with ACF admitted to Neonatal Unit of Xinhua Hospital.The data included maternalpregnancy and delivery history,clinical manifestation,results of chromosome florescent in situ hybridization(FISH) and gene chip test.Result Among 32 patients with classic ACF,8 were female and 24 weremale.5 cases were one of the twins or muhiplets.16 patients were born from mothers with history ofspontaneous abortion or induced abortion.16 patients presented with ACF on the left side and 16 patients onthe right side.7 patients had single ACF malformation,7 with malformation of another organ,and18 patients with malformation of more than two other organs.Combined malformation included earmalformation in 11 cases,facial malformation in 6 cases,cardiovascular malformation in 19 cases,urinarytract malformation in 3 cases,digestive system malformation in 3 cases,abnormal nervous system image in7 cases,and immune/endocrine system abnormality in 3 cases.10 patients received genetic analysis withFISH and/or gene chip tests and 4 patients had positive results.Among the patients who completed geneticanalysis,8 patients received FISH test and 2 patients had 22q11.2 distal deletion.1 patient hadheterozygous deletion in 22q21 region using gene chip test after he got a negative result with FISH.Amongthe 32 cases,6 patients died until now,among them,5 patients had multi-organ malformation.ConclusionACF is a tiny facial deformity,however it is often associated with other congenital malformations.Earlygenetic detection and systematic multiple malformations screening are particularly important for diagnosis andprediction of prognosis.

Clinical effects of en-bloc U-shaped osteotomy of the mandible in prominent mandibular angle patients with long chin / 中华医学美学美容杂志

Objective To discuss a surgical treatment to correct prominent mandibular angle with long chin.Methods From July 2015 to October 2017,21 patients with malocclusion who suffered from prominent mandibular angle with long chin underwent en-bloc mandibular U-shaped osteotomy through oralincision in order to shorten mandibular angle,the body of mandible and the chin and to improve the facial contour.We assessed the surgical effect through comparison of radiologic images,satisfaction of patients and surgical complications between pre-operation and post-operation.Results In this group,all oral incisions had healing by first intention,without hematoma,infection and osteonecrosis.Low lip numbness occurred in 16 patients.After following up for 6-12 months,the lower lip numbness was recovered in 14 patients and relieved in 2 patients.All patients satisfied with the appearance after the operation.Conclusions En-bloc mandibular U-shaped osteotomy is an improvement for mandible surgery treatment.Its osteotomy line involves the whole mandible,which makes the length and width of mandible smaller apparently.This procedure can effectively correct prominent mandibular angle with long chin.

Defeito ósseo de Stafne: relato de dois casos e considerações sobre o diagnóstico / Stafne bone defect: a report of two cases and diagnostic considerations

Defeitos ósseos de Stafne são cavidades ósseas assintomáticas localizadas em mandíbula, frequentemente causadas pela inclusão de tecidos moles. A variante comum desta entidade acomete a região de terceiros molares, abaixo do canal mandibular, sendo geralmente diagnosticada de forma incidental durante exames radiográficos de rotina. A variante em região anterior é incomum e localiza-se nas proximidades dos pré-molares mandibulares. Acredita-se que as glândulas salivares sublinguais estejam implicadas no desenvolvimento desta variante. O objetivo deste relato foi descrever um caso de defeito ósseo de Stafne na região anterior de mandíbula e um caso em mandíbula posterior, com ênfase nos achados clínicos e radiográficos. Cirurgiões dentistas deveriam ter conhecimento desta entidade para evitar biópsias desnecessárias. Na maioria dos casos, acompanhamento clínico-radiográfico constitui a conduta recomendada (AU)

Stafne bone defects are asymptomatic lingual bone depressions of the lower jaw, frequently caused by soft tissue inclusion. The common variant of this entity affects the third molar region, below mandibular canal, and is mostly diagnosed incidentally during routine radiographic examination. The uncommon anterior variant is relatively rare and located in the premolar region of the mandible. Sublingual salivary glands are thought to be responsible for the development of this variant. The aim of this report was to describe a case of Stafne bone defect in the anterior region of mandible and a case in posterior mandible, with emphasis on clinical and radiographic findings. Dental clinicians should be aware of this entity, aiming to avoid unnecessary biopsies. In most cases, clinical and radiographic follow-up is the recommended conduct (AU)

Avaliação estética da face em indivíduos com deformidades dentofaciais / Aesthetic face evaluation in individuals with Dentofacial Deformities

RESUMO Objetivo: analisar as características estéticas da face em indivíduos com deformidades dentofaciais (DDF) e os possíveis aspectos que se relacionam com aspectos da pele quanto às rugas e sulcos. Métodos: avaliou-se 36 adultos jovens (média de 27,22 anos), em três grupos, DDF padrão II, III e grupo controle (GC). Realizou-se análise facial utilizando o Protocolo de Avaliação Miofuncional Orofacial MBGR. Elaborou-se um protocolo de avaliação estético facial a partir das análises validadas para a classificação de rugas, linhas de marionete e sulcos na região orbicular dos olhos. Aplicaram-se testes estatísticos pertinentes. Resultados: indivíduos com DDF e 50% do GC apresentaram alteração quanto à assimetria facial e ângulo nasolabial, com diferença estatisticamente significante entre DDF-II, DDF-III e GC. Indivíduos com DDF mostraram maior frequência de alteração para os sulcos verticais na região dos lábios e linhas de marionete, sem diferenças entre os grupos. Houve correlação positiva entre sulco na região do prócero e os sulcos verticais nos lábios, sulco na região do orbicular dos olhos com o sulco nasogeniano e com as linhas de marionete. O ângulo nasolabial correlacionou-se com sulco na região da testa. A idade correlacionou-se com sulco nasogeniano, sulco na região do prócero, linhas de marionete e sulcos na região do orbicular dos lábios. Conclusão: indivíduos com DDF apresentaram alteração de simetria facial, ângulo nasolabial e da pele quanto às rugas. Aspectos estéticos da face correlacionaram-se entre si, bem como ângulo nasolabial com sulcos na testa. A idade também demonstrou relação com a estética facial.

ABSTRACT Purpose: to analyze the face aesthetic features of individuals with dentofacial deformities (DDF) and the possible aspects related to skin features such as wrinkles and grooves. Methods: we evaluated 36 young adults (average 27.22 years), in three groups, DDF standard II, III and control group (CG). Facial analysis was performed using the Orofacial Myofunctional Evaluation - MBGR Protocol. We developed a facial aesthetic evaluation protocol from validated analyzes for wrinkle classification, marionette lines and grooves in the orbicularis eye area. The relevant statistical tests were performed. Results: individuals with DDF and 50% of the control group showed changes regarding facial asymmetry and nasolabial angle, with a statistically significant difference between DDF-II, III and DDF-GC. Individuals with DDF presented a greater frequency of changes to the vertical grooves in the lips area as well as marionette lines, with no differences between groups. There was a positive correlation between procerus grooves and vertical lip grooves, grooves in the orbicularis eye region with nasolabial folds and marionette lines. The nasolabial angle was correlated with forehead grooves. Age correlated with nasolabial folds, grooves in the procerus area, marionette lines and lip grooves in the orbicular area. Conclusion: individuals with DDF presented alterations in their facial symmetry, nasolabial angle and skin regarding wrinkles. Facial aesthetic aspects correlated with each other as well as the nasolabial angle with forehead grooves. Age also showed a correlation with facial aesthetics.

Efeito da cirurgia ortognática na sensibilidade orofacial em indivíduos com fissura labiopalatina / Orthognathic surgery effect of orofacial sensitivity in individuals with cleft lip and palate

RESUMO: Objetivo: verificar a ocorrência de alterações na sensibilidade orofacial e o tempo de recuperação desta após a realização da cirurgia ortognática, em indivíduos com fissura labiopalatina. Métodos: após aprovação do Comitê de Ética em Pesquisa, iniciou-se o estudo o qual analisou os relatórios de exames miofuncionais orofaciais, realizados antes e após a cirurgia ortognática no período de 2012 a 2014. Foram selecionados 53 prontuários de pacientes que realizaram a prova de sensibilidade, com idade entre 18 e 40 anos, de ambos os gêneros (57% masculino e 43% feminino). A prova de sensibilidade foi aplicada nos lábios, na língua, na papila incisiva e mento, a partir do estesiômetro (Semmes-Weintein), antes da cirurgia (2 a 3 dias) e após a cirurgia (3 a 6 meses/9 a 12 meses). Os resultados foram analisados por meio de estatística descritiva para verificar a frequência de alteração da sensibilidade, e as comparações foram realizadas pelos testes de Wilcoxon e Qui-Quadrado (p<0,05). Resultados: antes da cirurgia todos os casos apresentaram sensibilidade adequada da língua, enquanto nas demais estruturas testadas poucos apresentaram alteração, antes e após a cirurgia ortognática. Após a cirurgia houve aumento da frequência de alteração da sensibilidade da papila palatina (p=0,004). Não houve associação entre os períodos de avaliação após a cirurgia. Conclusão: apesar da prevalência de adequação da sensibilidade, após a cirurgia foi observado para a papila incisiva aumento da frequência de alteração e não foi constatada diferença entre os casos avaliados antes e após 6 meses.

ABSTRACT: Purpose: to investigate the occurrence of changes in the orofacial sensitivity and the recovery time after the orthognathic surgery performance in individuals with cleft lip and palate. Methods: after the approval of the Research Ethics Committee, we started the study which analyzed the myofunctional orofacial reports, performed before and after orthognathic surgery from 2012 to 2014. We selected 53 medical records of patients who underwent sensitivity testing, aged between 18 and 40 years old, from both genders (57% male and 43% female). The sensitivity test was applied on the lips, tongue, incisive papilla and mental region, using the esthesiometer (Semmes-Weinstein), prior to surgery (2 to 3 days) and after surgery (3 to 6 months/9 to 12 months). The results were analyzed using descriptive statistics to verify the frequency of sensitivity change and comparisons were performed by Wilcoxon and Chi-square tests (p<0.05). Results: before surgery all cases showed adequate sensitivity of the tongue, while in the remaining few tested structures have changed before and after orthognathic surgery. After surgery there was an increase of frequency of sensitivity change in the incisive papilla (p=0.004). There was no association between the evaluation periods after surgery. Conclusion: although there was prevalence of sensitivity adequacy after surgery, it was observed, for the incisive papilla, an increased frequency of change and we found no difference between the cases evaluated before and after 6 months.
