RESUMO

BACKGROUND: Craniofacial microsomia (CM) is characterized by changes in the first and second branchial arches. It is a clinical condition whose etiology is still uncertain, but studies have shown that genetic, nutritional, and environmental factors can result in disorders of blastogenesis of the branchial arches. This study evaluates gestational aspects, focusing on possible risk factors associated with CM. METHODS: This is a case-control study conducted with patients monitored at a medical genetics service and compared to a control group of patients without evidence of malformations, born in a mother and child hospital, both located in Porto Alegre, Southern Brazil. Mothers' data were obtained using questionnaires and by reviewing medical records. The sample consisted of 43 patients with CM (cases) and 129 patients without evidence of malformations (controls), paired by sex, totaling three controls for each case. Data analysis was performed using the two-tailed Fisher's exact test, Pearson's chi-square test, and the t-test. RESULTS: We identified several factors associated with the development of CM, including the use of abortion methods by the mothers of these babies (p = .001), maternal diabetes (p = .009), advanced maternal age (p = .035), and a history of vaginal bleeding (p < .001). Furthermore, these patients exhibited a tendency to be born prematurely (p = .027), with low birth weight (p = .007), and lower Apgar scores (p = .003) when compared to healthy infants. Using a multivariate model, the use of abortion methods (p = .003) and vaginal bleeding (p = .032) remained independently associated with craniofacial microsomia. CONCLUSIONS: We have identified several risk factors for the development of CM, including a propensity for premature birth, low birth weight, and respiratory difficulties. Additionally, women of advanced maternal age and/or those who used abortion methods and/or have diabetes have a higher risk of giving birth to a baby with CM. This information can be valuable in clinical practice, especially for the prevention of future cases.

RESUMO

OBJECTIVE: To report associated congenital anomalies with unexplained craniofacial microsomia (CFM) and the phenotypic overlap with other recurrent constellations of embryonic malformations (RCEM), and to assess prenatal and perinatal risk factors. STUDY DESIGN: This is a retrospective cross-sectional study. Cases with CFM, delivered between January 1, 1997, and December 31, 2019, were abstracted from the population-based Alberta Congenital Anomalies Surveillance System. Livebirths, stillbirths, and early fetal losses were reviewed to include all types of pregnancy outcomes along the spectrum of this condition. Prenatal and perinatal risk factors were compared with the Alberta birth population to assess differences between the 2 groups. RESULTS: There were 63 cases with CFM, yielding a frequency of 1 per 16 949. There was a high rate of cases (65%) with anomalies outside the craniofacial and vertebral regions. Congenital heart defects were the most common (33.3%). A single umbilical artery was found in 12.7% of cases. The twin/triplet rate of 12.7% was significantly higher than the Alberta rate of 3.3% (P < .0001). There was an overlap with a second RCEM condition in 9.5% of cases. CONCLUSIONS: Although CFM is primarily a craniofacial condition, the majority of cases have congenital anomalies affecting other systems requiring additional assessments, including an echocardiogram, renal ultrasound examination, and a complete vertebral radiograph. The high rate of an associated single umbilical artery raises the possibility of a related etiological mechanism. Our findings support the proposed concept of RCEM conditions.

RESUMO

ABSTRACT Objective: To describe an infant with craniofacial microsomia and recurrent respiratory distress associated with aberrant right subclavian artery in order to review its most frequent congenital anomalies and alert the pediatrician to its rarer and more severe complications. Case description: This case report involves an 18-month-old male infant, only son of non-consanguineous parents. At birth, the child presented craniofacial dysmorphisms (facial asymmetry, maxillary and mandibular hypoplasia, macrostomia, grade 3 microtia, and accessory preauricular tag) restricted to the right side of the face. Additional tests showed asymmetric hypoplasia of facial structures and thoracic hemivertebrae. No cytogenetic or cytogenomic abnormalities were identified. The patient progressed to several episodes of respiratory distress, stridor, and nausea, even after undergoing gastrostomy and tracheostomy in the neonatal period. Investigation guided by respiratory symptoms identified compression of the esophagus and trachea by an aberrant right subclavian artery. After surgical correction of this anomaly, the infant has not presented respiratory symptoms and remains under multidisciplinary follow-up, seeking rehabilitation. Comments: Craniofacial microsomia presents a wide phenotypic variability compared to both craniofacial and extracraniofacial malformations. The latter, similarly to the aberrant right subclavian artery, is rarer and associated with morbidity and mortality. The main contribution of this case report was the identification of a rare anomaly, integrating a set of malformations of a relatively common condition, responsible for a very frequent complaint in pediatric care.

RESUMO Objetivo: Descrever lactente com microssomia craniofacial e desconforto respiratório recorrente associado à artéria subclávia direita aberrante, com o intuito de revisar as anomalias congênitas mais frequentes e alertar o pediatra sobre suas complicações mais raras e de maior gravidade. Descrição do caso: Lactente do sexo masculino, 18 meses de idade e filho único de casal não consanguíneo. Ao nascimento, foram observadas dismorfias craniofaciais (assimetria facial, hipoplasia maxilar e mandibular, macrostomia, microtia grau 3 e apêndice na linha trago-oral) restritas ao lado direito da face. Os exames complementares evidenciaram hipoplasia assimétrica da face e hemivértebras torácicas. Não foram identificadas anormalidades citogenéticas ou citogenômicas. O paciente evoluiu com diversos episódios de desconforto respiratório, estridor e náuseas, mesmo tendo realizado gastrostomia e traqueostomia no período neonatal. A investigação direcionada para os sintomas respiratórios identificou a compressão de esôfago e traqueia por uma artéria subclávia direita aberrante. Após a correção cirúrgica dessa anomalia, o lactente não tem apresentado sintomas respiratórios e mantém seguimento multidisciplinar buscando reabilitação. Comentários: A microssomia craniofacial apresenta grande heterogeneidade fenotípica em relação às malformações tanto craniofaciais como extracraniofaciais. Estas últimas, como a artéria subclávia direita aberrante, são mais raras e associadas à morbimortalidade. A principal contribuição deste relato de caso foi o reconhecimento de uma anomalia rara, integrando um conjunto de malformações de uma condição relativamente comum e sendo responsável por uma queixa muito frequente no atendimento pediátrico.

RESUMO

INTRODUCCIÓN: El síndrome de Goldenhar es un trastorno heterogéneo, esporádico en su mayoría o por patrón de herencia autosómico dominante o recesivo, de la morfogénesis craneofacial asociada al primero y segundo arcos faríngeos, y forma parte del espectro oculoauriculovertebral. La incidencia es de 1 por cada 3500-45,000 recién nacidos vivos, con una razón de sexo masculino/femenino de 3:2. CASO CLÍNICO: Se presenta el caso de un recién nacido con fenotipo de síndrome oculoauriculovertebral. Se abordó con radiografía de tórax, ecografía abdominal y tamizaje metabólico y auditivo, que reportaron hemivértebra torácica, fusión costal, quiste renal e hipoacusia bilateral profunda, respectivamente. Fue alimentado con lactancia mixta desde el nacimiento, sin lograr una succión adecuada y con pérdida de peso. A los 3 meses de edad recibió terapia de rehabilitación oral con electroestimulación en conjunto de 10 sesiones con 10 mA de intensidad, al igual que a los 23, 24, 25, 27, 30 y 32 meses de edad. A los 4 meses, espesamiento de fórmula con cereal; a los 7 meses, sonda de gastrostomía; a los 20 meses, cirugía de paladar y macrostomía. Mostró mejoría en intensidad de babeo en las primeras 10 sesiones y mejoría en la deglución a las 30 sesiones. A los 3 años de edad consume el 100% de los alimentos por vía oral. CONCLUSIONES: Con la escasa evidencia científica que este caso aislado aporta, el tratamiento con la terapia de rehabilitación en conjunto con la terapia convencional y la corrección anatómica dio resultados positivos para el trastorno de la deglución. BACKGROUND: Goldenhar syndrome is a heterogeneous disorder, mostly sporadic or due to a dominant autosomal or recessive pattern of inheritance, that exhibits craniofacial morphogenesis associated with the first and second pharyngeal arches and is part of the oculoauriculovertebral spectrum. Its incidence is of 1 in 3,500-45,000 live newborns, with a male to female ratio of 3:2. CASE REPORT: We describe the case of a male newborn with oculoauriculovertebral syndrome phenotype. It was approached with chest X-ray, abdominal ultrasound, metabolic and hearing screening, which reported thoracic hemivertebra, costal fusion, renal cyst, and profound bilateral hypoacusis, respectively. Although the newborn was fed with mixed lactation from birth, adequate suction and with weight loss were not achieved. At 3 months of age, as well as at 23, 24, 25, 27, 30 and 32 months of age, the infant received oral rehabilitation therapy with electrostimulation in a set of 10 sessions with 10 mA intensity. At 4 months, thickening of formula with cereal; at 7 months, gastrostomy tube; at 20 months, palate surgery and macrostomy. Improvement in drooling intensity was observed during the first 10 sessions, and improvement in swallowing after 30 sessions. At 3 years of age, the patient consumes 100% of food orally. CONCLUSIONS: According to limited scientific evidence that this isolated case provides, rehabilitation therapy together with conventional therapy coupled with anatomical correction gave positive results for swallowing disorder.

RESUMO

OBJECTIVES: The objectives of this study were to characterize the craniofacial and airway morphology of oculo-auriculo-vertebral spectrum (OAVS) individuals using computed tomography (CT) examination. SETTING AND SAMPLE POPULATION: This sample included individuals in the age range from 5 to 14 years, consisted of a group of 18 OAVS individuals (12 females and 6 males), Pruzansky-Kaban1 IIB and III and by a paired control group matched by age and sex for comparison of morphometric and airway variables. MATERIALS AND METHODS: Through the CT examination, airway analysis was performed using Dolphin Imaging® Software, and seven morphometric measurements were performed to evaluate craniofacial morphology by Materialize Mimics® Software. To compare airway and morphometric variables, the control group was used. Student's t test and Mann-Whitney U test were performed to compare differences between the groups. RESULTS: Statistically significant differences were showed between the control and OAVS groups for the variables: total airway (TA) area, volume and MAA, RP area, RP volume, RP MAA, RG volume, RG MAA, total posterior height diff, Md incl and y-axis asymmetry. Pearson and Spearman's correlation showed mostly moderate correlations between Mand Occlusal canting AS with TA area and RP volume, Ax-Gn with TA area and Hy-C3 with TA volume. CONCLUSIONS: The OAVS's airway was altered and worse than the control group. Our results suggest that the contralateral side of OAVS individuals is unaffected; however, longitudinal assessments are needed to confirm it. Hyoid bone and postural measures play an important role in interpreting airway features of individuals with and without OAVS.

RESUMO

The article describes a case of Goldenhar syndrome that had been diagnosed by an ophthalmologist in a medical consultation by school bullying due to a choristoma. A 15-year-old male patient, who had a nodular lesion with hair in the inferior temporal corneal-limbo-conjunctival of the left eye, was reported. He also had a facial asymmetry, with mild mandibular hypoplasia and malformation of the left external ear, where only an auricular appendage was formed. He denied similar family history and the history of genetic diseases, but revealed that his mother had used ibuprofen during the first 3 months of pregnancy and had gestational diabetes mellitus. Excisional biopsy of the eye lesion was performed and revealed a dermoid cyst. After the exegesis and with adequate multidisciplinary monitoring, the patient reported being very satisfied with the aesthetic result, returning with more confidence to his daily activities. That was a typical case of Goldenhar syndrome that has remained undiagnosed and untreated for more than a decade due to a lack of diagnosis despite its classic presentation. The delay in the approach resulted in social stigma and profound psychosocial damage. The importance of disseminating the correct knowledge of this pathology and of having an early multidisciplinary approach in these patients is emphasized, since the impact on the quality of life is significantly high.

RESUMO

The aim of this study was to perform 22q11.2 deletion screening and chromosomal microarray analysis (CMA) in individuals clinically diagnosed with craniofacial microsomia (CFM) and review previously published cases of CFM with genomic imbalances. It included 54 individuals who were evaluated by a clinical geneticist. Copy number variants (CNVs) in the 22q11.2 region were investigated by multiplex ligation-dependent probe amplification (MLPA) for all individuals. The CMA was performed only for individuals with additional major features. MLPA revealed pathogenic CNVs at the 22q11 region in 3/54 (5.6%) individuals. CMA revealed pathogenic CNVs in 4/17 (23.5%) individuals, including the three CNVs at the 22q11 region also detected by MLPA, and CNVs classified as variants of unknown significance (VOUS) in 4/17 (23.5%) individuals. Pathogenic alterations were found at the 2p12, 5p15, 13q13, and 22q11 regions. VOUS were found at 3q29, 5q22.2, 5q22.1, and 9p22 regions. All individuals with pathogenic alterations presented additional major features, including congenital heart disease (CHD). The literature review revealed pathogenic CNVs in 17/193 (8.8%) individuals and most of them also presented additional major features, such as CHD, renal anomalies, or developmental delay. In conclusion, CNVs should be investigated in patients with CFM and additional major features.

RESUMO

Oculoauriculovertebral spectrum (OAVS) is a rare class of heterogenous congenital craniofacial malformation conditions of unknown etiology. Although classic OAVS has been described as hemifacial microsomia with facial asymmetry and microtia, there is no consensus regarding clinical criteria for diagnosis or genetic cause. This systematic review aims to assess the applicability of high-resolution (HR) karyotype, fluorescence in situ hybridization, multiplex ligation-dependent probe amplification (MLPA), and microarray-based comparative genomic hybridization (array-CGH) for differential diagnosis of OAVS. A search was performed in PubMed and Web of Science using all entry terms to the following descriptors: Goldenhar's syndrome, cytogenetic analysis, hybridization in situ, fluorescent, comparative genomic hybridization, multiplex polymerase chain reaction, whole genome sequencing, and karyotype analysis methods. After screening, 25 articles met eligibility. Of the included studies, 59 individuals had a genetic alteration identified. Array-CGH, MLPA, and HR karyotype appear to be viable approaches for molecular diagnosis in OAVS. Heterogeneity is a hallmark of OAVS. Establishing an enhanced framework for diagnosis would inform clinical decision making, and better resource utilization could improve health care facility efficiency and economy.

RESUMO

OBJECTIVE: To present our experience treating 42 patients with Goldenhar syndrome. METHOD: A descriptive, observational, retrospective study was carried out using the medical and photographic record of all patients diagnosed with Goldenhar syndrome treated by the craniofacial surgery unit of the plastic and reconstructive surgery department of the Dr. Manuel Gea González hospital between 2010 and 2018. RESULTS: A total of 42 patients were obtained,54% male of which all underwent at least one procedure. The majority of patients were of the first decade of age (57%). Surgical procedures could be divided mainly into 14 auricular (20%), 17 mandibular (24%), 2 Lefort (4%), 10 volume (14%), 9 macrostoma (13%) and 16 other (21%). A total of 71 procedures were performed. CONCLUSION: Goldenhar syndrome is a rare entity that affects various structures, which is why an early diagnosis and multidisciplinary management headed by a team of plastic surgeons is necessary.

RESUMO

The oculoauriculovertebral spectrum (OAVS) is characterized by anomalies involving the development of the first and second pharyngeal arches during the embryonic period. The phenotype is highly heterogeneous, involving ears, eyes, face, neck, and other systems and organs. There is no agreement in the literature for the minimum phenotypic inclusion criteria, but the primary phenotype involves hemifacial microsomia with facial asymmetry and microtia. Most cases are sporadic and the etiology of this syndrome is not well known. Environmental factors, family cases that demonstrate Mendelian inheritance, such as preauricular appendages, microtia, mandibular hypoplasia, and facial asymmetry; chromosomal abnormalities and some candidate genes suggest a multifactorial inheritance model. We evaluated clinical, cytogenomic and molecularly 72 patients with OAVS, and compared our findings with patients from the literature. We found 15 CNVs (copy number variations) considered pathogenic or possibly pathogenic in 13 out of 72 patients. Our results did not indicated a single candidate genomic region, but recurrent chromosomal imbalances were observed in chromosome 4 and 22, in regions containing genes relevant to the OAVS phenotype or related to known OMIM diseases suggesting different pathogenic mechanisms involved in this genetically and phenotypic heterogeneous spectrum.

RESUMO

Craniofacial Microsomia (CFM) also known as Oculo-auriculo-vertebral Spectrum (OAVS) or Goldenhar Syndrome, presents wide phenotypic and etiological heterogeneity. It affects mainly the structures originated from the first and second pharyngeal arches. In addition, other major anomalies may also be found, including congenital heart diseases. In this study, we report a patient with distal deletion in the 22q11.2 region and a phenotype which resembles CFM. The proband is a girl, who presented bilateral preauricular tags, left auditory canal stenosis, malar hypoplasia, cleft lip and palate, mild asymmetry of soft tissue in face, congenital heart disease, intestinal atresia, annular pancreas and hydronephrosis. The genomic imbalances investigation by Multiplex Ligation-dependent Probe Amplification (MLPA) and Chromosomal Microarray Analysis (CMA) revealed a distal deletion of 1,048 kb at 22q11.2 encompassing the region from Low Copy Repeats (LCRs) D to E. We did review of the literature and genotype-phenotype correlation. This is the sixth case of distal 22q11.2 deletion resembling CFM and the second encompassing the region between LCRs D to E. All cases share some phenotypic signs, such as preauricular tags, facial asymmetry, cleft lip and palate, and congenital heart diseases. Candidate genes in this region have been studied by having an important role in pharyngeal arches developmental and in congenital heart diseases, such as HIC2, YPEL1and MAPK1/ERK2. This case corroborates the phenotypic similarity between 22q11.2 distal deletion and CFM/OAVS. It also contributes to genotype-phenotype correlation and reinforces that candidate genes for CFM, in the 22q11.2 region, might be located between LCRs D and E.

RESUMO

Oculoauriculovertebral spectrum (OAVS), also known as Goldenhar syndrome, is considered a condition associated to failing of embryogenesis involving the first and second branchial arches, leading to structural abnormalities arising from it. The aim of this study is to verify the hearing features presented by patients with OAVS and provide additional information that may contribute to improvement of speech therapy. The sample consisted of 10 individuals diagnosed with OAVS and cared for by the Clinical Genetics Service. All patients underwent objective assessment of auditory function through tonal and vocal audiometry. This evaluation was completed using TOAE and BERA. The patient's age ranged from 1 year and 9 months to 27 years and 4 months. At physical examination it was found that 10 had microtia, 7 preauricular tags, 6 low-set ears, 6 ear canal atresia, and 2 preauricular pits. Among the patients, five presented with abnormal hearing. Three patients had conductive hearing loss ranging from mild to moderate, and two patients had sensorineural hearing loss from mild to profound. Three patients had hearing loss in both ears. Speech-language disorders are common in children with OAVS. Thus, the referral to the audiologist and speech pathologist is indicated as soon as possible. Early recognition and detailed understanding of aspects related to the etiology, clinical features, and outcome of patients with OAVS are essential for their proper management. © 2016 Wiley Periodicals, Inc.

RESUMO

El manejo de la vía aérea representa un reto constante en la práctica de la anestesiología pediátrica, más aun en los pacientes que presentan vía aérea difícil anticipada como son los pacientes pediátricos con malformaciones craneofaciales. En paciente con vía aérea difícil como lo son los pacientes con malformaciones craneofaciales se considera el uso de fibroscopia flexible como el gold standard en la intubación, sin embargo la traqueostomía es una opción que debe considerarse en todos los casos de vía aérea difícil. A continuación se presenta una revisión bibliográfica en la que se expone el manejo de la vía aérea dificil comprendiendo las variaciones anatómicas y fisiológicas como las que se presentan en los pacientes con síndrome de Goldenhar y síndrome Nager.

Airway management represents a constant challenge in the practice of pediatric anesthesiology, even more so in patients who present difficult airways as are pediatric patients with craniofacial malformations. In patients with difficult airways such as patients with craniofacial malformations, the use of flexible fibroscopy as the gold standard in intubation is considered, but tracheostomy is an option that should be considered in all cases of difficult airway. The following is a bibliographic review in which the management of the airway is difficult, including anatomical and physiological variations such as those present in patients with Goldenhar syndrome and Nager syndrome.

RESUMO

ABSTRACT Goldenhar Syndrome is a rare, generally sporadic condition, whose physical manifestations include asymmetric incomplete facial development, epibulbar dermoids, auricular malformations e auricular appendices, vertebral anomalies, central nervous system disturbances, ocular irregularities and visceral abnormalities. Its etiology is not fully understood, with its incidence ranging from 1:3500 to 1:5600 live births, and a gender ratio of 3:2 (male: female), presenting more frequently in children with congenital deafness. The purpose of this case report was to describe clinical presentation of Goldenhar syndrome in a five-year old male with no significant family history, where almost all of the classic signs of the condition were present. Considering its involvement in craniofacial structures, its rarity, and its wide spectrum of symptoms and associated systemic abnormalities, knowledge of this condition is paramount for the dental surgeon.

RESUMO A Síndrome de Goldenhar é rara e suas principais manifestações físicas incluem assimetria e desenvolvimento facial incompleto, tumores dermoides epibulbares, malformações na orelha e apêndices auriculares, anomalias vertebrais, distúrbios no sistema nervoso central, irregularidades oculares e anomalias viscerais. A etiologia desta condição não é claramente esclarecida e apresenta-se geneticamente variável. A incidência da Síndrome de Goldenhar pode variar de 1:3500 até 1:5600 nascidos vivos e relação por sexo de 3:2 (masculino: feminino), apresentando mais frequentemente em crianças com surdez congênita. O objetivo deste trabalho é apresentar um caso clínico de Síndrome de Goldenhar em paciente infantil de 5 anos de idade do sexo masculino, sem história familiar relevante relacionada à síndrome e que apresenta características claras desta condição. Considerando o envolvimento das estruturas craniofaciais da Síndrome de Goldenhar, sua raridade e o amplo espectro de sintomas e anormalidades sistêmicas associadas, o conhecimento desta condição é primordial para o cirurgião-dentista.

RESUMO

Resumen: El síndrome de Goldenhar en honor al Dr. M. Goldenhar suele reservarse para los casos que presentan microsomía hemifacial. Este síndrome suele afectar principalmente maxilar, mandíbula, pabellón auricular, globo ocular y tejidos adyacentes de una hemicara. El objetivo de esta rehabilitación es devolver en medida de lo posible, la función masticatoria y estética al paciente. A continuación se presenta la rehabilitación intraoral de una paciente con síndrome de Goldenhar que acudió a la clínica de PMF presentando edentulismo total hipoplasia maxilar y mandibular (esta última compensada con una cadena de titanio). Se realizó rehabilitación protésica bimaxilar, teniendo en cuenta la asimetría facial, la limitación de movimiento mandibular y la disminución de los procesos alveolares. El tratamiento fue enfocado principalmente en mejorar la función masticatoria, fonética y estética, que en conjunto son determinantes en la cotidianidad del paciente y su calidad de vida.

Abstract: Goldenhar's syndrome, named after Dr M Goldenhar, is normally reserved for cases presenting hemi-facial microsomy. This syndrome normally affects upper and lower jaws, pinna, and adjacent tissues in a hemi-face. The target of this rehabilitation is to restore to its maximum possible extent patient's esthetics and masticatory function. We present intra-oral rehabilitation of a Goldenhar Syndrome patient who attended the maxillofacial prosthesis clinic. The patient exhibited complete edentulism, maxillary and mandibular hypoplasia (this latter compensated with a titanium chain). Prosthetic bi-maxillary rehabilitation was undertaken, bearing in mind circumstances of facial asymmetry, mandibular movement limitations and decreased alveolar ridges. Treatment was mainly focused on improvement of esthetic, phonetic and masticatory functions, which, as a whole are crucial in patient's day-to-day life and quality of life.

RESUMO

SUMMARY Objective: To describe the most prominent clinical features of a cohort of patients with oculo-auriculo-vertebral (OAV) dysplasia in Brazil. Method: A review of medical records of patients with diagnosis of OAV from 1990 to 2010 was performed in a medical genetics center. Results: 41 patients were included in the study. Their average age at diagnosis was 2y 10mo (34,4±48,8 months) and the female proportion was 53.7%. Mean maternal age at patient’s birth was 28.5y (min: 17, max: 46y) for mothers and 31.4y (min: 21, max: 51y) for fathers. Most patients (97.5%) had auricular involvement, with facial manifestation in 90.2%, spinal in 65.9%, ocular in 53.7%, 36.6% with cardiovascular involvement, 29.3% urogenital, and 17% of the cases with central nervous system (CNS) involvement. The classic OAV triad was present in only 34%. All patients except one had concomitant problems in other organs or systems. Conclusion: Since the diagnosis of OAV dysplasia relies only on a comprehensive medical evaluation, it is imperative that clinicians be aware of the most common presentation of the syndrome. Once suspected, every patient should undergo a complete medical evaluation of multiple systems including complementary exams. Treatment of these patients is based on surgical correction of malformations and rehabilitation.

RESUMO Objetivo: descrever os principais achados clínicos de uma coorte de pacientes com a displasia óculo-aurículo-vertebral (OAV). Método: revisão de prontuários médicos dos pacientes com diagnóstico de OAV no período de 1990 a 2010, acompanhados em um centro de genética médica. Resultados: foram incluídos no estudo 41 pacientes. A média de idade ao diagnóstico foi de 2 anos e 10 meses (34,4±48,8 meses) e a proporção de pacientes do sexo feminino foi de 53,7%. A média de idade dos pais ao nascimento do paciente foi de 28,5±6,9 anos para as mães e 31,4±7,4 anos para os pais. A maioria dos indivíduos (97,5%) possuía acometimento auricular, 90,2% tinham manifestações faciais, 65,9%, vertebrais, 53,7%, oculares, 36,6%, cardiovasculares, 29,3%, urogenitais e 17%, no sistema nervoso central. Além disso, 34% dos pacientes apresentavam a tríade clássica óculo-aurículo-vertebral, e todos os pacientes exceto um apresentavam concomitantemente problemas em outros órgãos ou sistemas. Conclusão: já que o diagnóstico desta entidade é eminentemente clínico, é imprescindível que os médicos das mais diversas especialidades conheçam os achados mais frequentes na OAV. Diante de um paciente com suspeita diagnóstica, deve ser realizada avaliação detalhada de outros órgãos, tanto clínica como por meio de exames complementares. O tratamento é baseado na correção cirúrgica das malformações e na reabilitação.
