Reconstrução nasal com uso de costela em paciente com síndrome de Binder: Um relato de caso e revisão de literatura / Nasal reconstruction using ribs in a patient with Binder syndrome: A case report and literature review

Introdução: A síndrome de Binder também pode ser conhecida como displasia maxilonasal e é uma malformação congênita caracterizada por hipoplasia nasomaxilar devido a um subdesenvolvimento do esqueleto facial médio. A atual incidência ou prevalência ainda é desconhecida, mas afeta aproximadamente um recém-nascido vivo em cada 10.000 nascimentos. O diagnóstico pode ser clínico ou associado a ultrassonografia pré-natal, caracterizada por nariz achatado e convexidade anormal da maxila. O tratamento é cirúrgico para correção das anormalidades estéticas e funcionais. Relato de Caso: Paciente que recebeu diagnóstico de síndrome de Binder aos 14 anos, sem outras malformações associadas, com queixa estética e funcional nasal. A correção cirúrgica foi iniciada pela extração de um bloco da sexta cartilagem costal à esquerda, com abertura nasal na margem columelar, no padrão de uma rinoplastia aberta, e dissecados os tecidos no plano subSMAS. Após preparo da área receptora nasal, foram esculpidos bloco de cartilagem para reconstrução do dorso nasal, enxertos alares e enxerto de cartilagem septal. Houve melhora de projeção da ponta nasal e alongamento nasal. Conclusão: A rinoplastia pode ser uma cirurgia desafiadora nesses pacientes, sendo a reconstrução autóloga com o uso de cartilagem costal indicada pela literatura como a melhor opção. É necessário individualizar cada caso para programação de enxertos e reestruturação nasal, sendo fundamental também a melhora funcional desses casos.

Introduction: Binder's syndrome can also be known as maxillonasal dysplasia and it is a congenital malformation characterized by nasomaxillary hypoplasia resulting from an underdevelopment of the middle facial skeleton. The current incidence or prevalence is still unknown, but it affects approximately one child in every 10,000 births. The diagnosis can be clinical or associated with prenatal ultrasonography, characterized by a flattened nose and abnormal maxillary convexity. The treatment is surgical to correct aesthetic and functional abnormalities. Case Report: Patient diagnosed with Binder's syndrome at the age of 14, without other associated malformations, with aesthetic and functional nasal complaints. Surgical correction began with the extraction of a block of the sixth costal cartilage on the left, with a nasal opening on the columellar margin, in the pattern of an open rhinoplasty, and tissue dissection in the sub-SMAS plane. After preparing the nasal receptor area, a block of cartilage was sculpted for reconstruction of the nasal dorsum, alar grafts and septal cartilage grafts. There was an improvement in the projection of the nasal tip and nasal dorsum. Conclusion: Rhinoplasty can be a challenging surgery in these patients, and the literature indicates that the best option is autologous reconstruction with costal cartilage. It is necessary to individualize each case to schedule nasal grafts and restructuring, and functional improvement in these cases is also essential

Fibrous dysplasia: rare manifestation in the temporal bone / Displasia fibrosa: manifestação rara no osso temporal

Abstract Introduction: Fibrous dysplasia is a benign disorder, in which normal bone is replaced by fibrosis and immature bone trabeculae, showing a similar distribution between the genders, and being more prevalent in the earlier decades of life. Fibrous dysplasia of the temporal bone is a rare condition, and there is no consensus as to whether it is more common in monostotic or polyostotic forms. External auditory meatus stenosis and conductive dysacusis are the most common manifestations, with cholesteatoma being a common complication, whereas the involvement of the otic capsule is an unusual one. Surgical treatment is indicated to control pain or dysacusis, otorrhea, cholesteatoma, and deformity. Objectives: To describe the clinical experience of a tertiary referral hospital with cases of fibrous dysplasia of the temporal bone. Methods: Sampling of patients diagnosed with fibrous dysplasia of the temporal bone, confirmed by tomography, treated at the pediatric otology and otorhinolaryngology outpatient clinics, between 2015 and 2018. The assessed variables were age, gender, laterality, external auditory meatus stenosis, deformity, hearing loss, presence of secondary cholesteatoma of the external auditory meatus, lesion extension and management. Results: Five patients were included, four females and one male, with age ranging from 13 to 34 years. Three had the polyostotic form and two the monostotic form of fibrous dysplasia of the temporal bone. Four patients had local deformity and external auditory meatus stenosis, two of which progressed to cholesteatoma. All patients showed some degree of hearing impairment. All had preserved otic capsule at the tomography. Two patients are currently undergoing clinical observation; two were submitted to tympanomastoidectomy due to secondary cholesteatoma; one was submitted to lesion resection, aiming to control the dysacusis progression. Conclusion: Five cases of fibrous dysplasia of the temporal bone were described, a rare disorder of which the otologist should be aware.

Resumo Introdução: Displasia fibrosa é uma desordem benigna, na qual o osso é substituído por fibrose e trabeculado ósseo imaturo, com distribuição semelhante entre sexos, mais comum nas primeiras décadas de vida. O acometimento do osso temporal pela displasia fibrosa é raro, não há consenso se é mais comum nas formas monostóticas ou poliostóticas. Estenose do meato acústico externo e disacusia condutiva são as manifestações mais comuns. Colesteatoma é também uma complicação comum e o acometimento da cápsula ótica incomum. O tratamento cirúrgico está indicado para controle de dor ou disacusia, otorreia, colesteatoma, deformidade. Objetivos: Descrever a experiência clínica de hospital terciário de referência com casos de displasia fibrosa do osso temporal. Método: Amostragem dos pacientes com diagnóstico de displasia fibrosa do osso temporal, confirmado pela tomografia, atendidos nos ambulatórios de otologia e otorrinolaringologia pediátrica, entre 2015 e 2018. As variáveis avaliadas foram idade, gênero, lateralidade, estenose do meato acústico externo, deformidade, perda auditiva, presença de colesteatoma secundário de meato acústico externo, extensão da lesão e conduta adotada. Resultados: Foram incluídos cinco pacientes, quatro do sexo feminino e um masculino, de 13-34 anos. Três apresentaram a forma poliostótica da displasia fibrosa do osso temporal e dois a forma monostótica. Quatro apresentaram deformidade local e estenose do meato acústico externo, dois desses evoluíram com colesteatoma. Todos manifestaram algum grau de comprometimento auditivo. Todos apresentaram cápsula ótica preservada na tomografia. Duas pacientes estão em observação clínica; duas foram submetidas a timpanomastoidectomia devido a colesteatoma secundário; um foi submetido a ressecção da lesão para controle de progressão da disacusia. Conclusão: Foram descritos cinco casos de displasia fibrosa do osso temporal, desordem rara para a qual o otologista deve estar atento.

Treacher Collins Syndrome: A Rare and Special Case Report of a 9-Year-Old Boy from Saudi Arabia

Treacher Collins syndrome (TCS) is characterized by downslanting palpebral fissures on both sides, malar hypoplasia, micrognathia, and external ear abnormalities. Hypoplasia of the zygomatic bones and jaw may make it difficult to eat and breathe. TCS, also known as Franceschetti syndrome or mandibulofacial dysostosis, is an autosomal dominant craniofacial condition with a wide range of symptoms. Edward Treacher Collins (1862?1932), an English ophthalmologist, first defined the syndrome’s fundamental characteristics in 1900. This syndrome is approximately affecting 1 in 50,000 live births with equal gender affection. In Saudi Arabia, it follows a similar pattern of prevalence. Antimongoloid slanting palpebral fissures, colobomas of the lower eyelid, hypoplasia of the zygoma and mandible, auditory microtia, conductive hearing loss, obstructive sleep apnea, and a range of orofacial abnormalities are the most prevalent clinical symptoms of TCS. In this case report, the author describes a deep-rooted analysis of the clinical features of TCS in a 9-year-old boy as well as his follow-up case. The study was conducted for a period of 9 years from birth to 9 year-old age, which makes this case report as a special rare 9-year follow-up case report from Saudi Arabia.

Clinical and Radiological Characterisation of Patients with Mucopolysaccharidosis in a Genetic Clinic

Abstract The mucopolysaccharidoses (MPS) are a relatively uncommon group of inherited metabolic disorders. MPSs should be suspected in a child with coarse facies, organomegaly, recurrent respiratory tract infections, developmental delay, and hernias. Early diagnosis and treatment can greatly improve the quality of life in these children. In this study we studied 46 MPS patients diagnosed on enzyme and/or DNA testing and we found that the MPS II was the most common type followed by MPS I and MPS IVA. While the mean age of onset of symptoms was 12 months, the mean age at diagnosis was 4.5 years, a significant delay. One of major presenting features was recurrent respiratory problems, more prevalent in MPS II cases. Many patients also had short stature and contractures. Increasing awareness among physicians is of paramount importance for the early diagnosis and optimal treatment and prevention by prenatal testing and counselling.

Manifestações bucais em uma paciente com disostose cleidocraniana: relato de caso / Oral manifestations in a patient with cleidocranial dysostosis: case report

A Disostose Cleidocraniana (DC), também conhecida como Displasia Cleidocraniana (DCC), é uma doença autossômica de caráter dominante, relatada pela primeira vez no século XVIII, sendo descrita em 1897 por Pierre Marie e Paul Sainton, relacionando-a a fatores genéticos. Suas manifestações clínicas apresentam-se através do desenvolvimento tardio de estruturas e defeitos ósseos, anormalidades estomatognáticas e craniofaciais. O diagnóstico baseia-se nas características clínicas e imaginológicas e o tratamento odontológico geralmente é cirúrgico, envolvendo a exodontia de unidades supranumerárias e decíduas, em associação com a abordagem ortodôntica. Este trabalho possui como objetivo, relatar o caso clínico sobre as principais manifestações bucais evidenciadas em uma paciente jovem diagnosticado com Displasia Cleidocraniana, bem como demonstrar a importância do diagnóstico preciso para auxílio no sucesso do tratamento e qualidade de vida do paciente(AU)

Cleidocranial Dysostosis (CD), also known as Cleidocranial Dysplasia (DCC), is an autosomal dominant disease, first reported in the 18th century, being described in 1897 by Pierre Marie and Paul Sainton, relating it to genetic factors. Its clinical manifestations appear through the late development of bone structures and defects, stomatognathic and craniofacial abnormalities. The diagnosis is based on clinical and imaging characteristics and dental treatment is usually surgical, involving the extraction of supernumerary and deciduous units, in association with the orthodontic approach. This work aims to report the clinical case about the main oral manifestations evidenced in a young patient diagnosed with Cleidocranial Dysplasia, as well as to demonstrate the importance of accurate diagnosis to aid in the success of the treatment and quality of life of the patient(AU)

Síndrome de Scheuthauer Marie Sainton / Scheuthauer-Marie-Sainton syndrome

RESUMEN El síndrome de Scheuthauer Marie Sainton es una enfermedad poco frecuente, que sigue un patrón de herencia autosómico dominante con expresividad variable. Se presenta paciente masculino de 74 años de edad, nacido por parto distócico (cesárea) producto a una desproporción cefalopélvica materna. Acudió a la consulta de Medicina General Integral, del Policlínico Docente "Efraín Mayor Amaro", municipio Cotorro, La Habana, con tos y secreción nasal. Se interpretó como un catarro común para lo cual se le indicó abundantes líquidos, analgésicos, antihistamínicos y vitamina C. En el examen físico se constató que el paciente padecía del síndrome de Scheuthauer Marie Sainton, pues tenía ausencia de ambas clavículas, deformidades óseas y anomalías dentales; además, se detectó tórax acampanado, el cual es evidente en el período de recién nacido. Para el tratamiento de esta enfermedad, el paciente fue remitido a la consulta de estomatología. Desde el punto de vista óseo, no se realizó ninguna cirugía correctora a voluntad del paciente(AU)

ABSTRACT Scheuthauer Marie Sainton syndrome is a rare disease that follows an autosomal dominant pattern of inheritance with variable expressivity. We report a case of a 74-year-old male patient, who was born by dystocic delivery (cesarean section) due to maternal cephalopelvic disproportion. He went to the Comprehensive General Medicine consultation at Efraín Mayor Amaro Teaching Community Clinic, Cotorro municipality, Havana, with a cough and runny nose. It was interpreted as a common cold and he was prescribed abundant fluids, analgesics, antihistamines and vitamin C. On physical examination it was found that the patient suffered from Scheuthauer Marie Sainton syndrome, as he had absence of both clavicles, bone deformities and dental abnormalities. In addition, he was noticed to have flared chest, which is evident in the newborn period. The patient was referred to the stomatology consultation for the treatment of this disease. No corrective bone surgery was performed at the patient's discretion(AU)

RÉSUMÉ Le syndrome de Scheuthauer-Marie-Sainton est une maladie peu fréquente, qui suit un modèle de transmission autosomique dominante à expression variable. Un patient âgé de 74 ans, né par accouchement dystocique (césarienne) dû à une disproportion céphalo-pelvienne maternelle, est présenté. Du fait de la toux et des sécrétions nasales, il est allé à la consultation de médecine générale intégrale, de la polyclinique universitaire Efrain Mayor Amaro, dans la municipalité de Cotorro, à La Havane. Un rhume a été considéré, c'est pourquoi on lui a indiqué de prendre des boissons en abondance, et prescrit des analgésiques, des antihistaminiques et de la vitamine C. Dans l'examen physique, on a pu constater que le patient était atteint de syndrome de Scheuthauer-Marie-Sainton, caractérisé par l'absence complète des clavicules, des difformités osseuses et des anomalies de la denture ; on a aussi trouvé un thorax évasé, très évident chez le nouveau-né. Pour le traitement de cette maladie, le patient a été dirigé à la consultation de stomatologie. Du point de vue osseux, aucune chirurgie de correction n'a été effectuée en respectant la volonté du patient(AU)

A rare case of Sprengel deformity associated with spondylocostal dysostosis in a four-year child

Sprengel deformity is a complex congenital anomaly affecting one or both scapulae with mispositioning and dysplasia of scapula. It occurs due to failure of descent of scapula during intrauterine development and is the commonest congenital skeletal deformity of the scapula, often associated with other skeletal deformities. spondylocostal dysostosis is a rare genetic disorder which is characterized by malformation of the bones of the spine and ribs. It occurs in approximately 1 in 2,00,000 people worldwide. In spondylocostal dysostosis, affected children have wedge shaped vertebrae along with ribs that are fused, forked or sometimes missing. Based on the severity of the defect's children may present with short stature, scoliosis or hypoplasia of lungs causing difficulty in breathing and recurrent respiratory tract infections. Management of both these skeletal deformities depends on their severity and the presence of associated deformities. Surgical intervention might be required for cosmetic and functional recovery of the shoulder. Authors had a rare and interesting case of a 4-year-old boy who had features of Sprengel deformity affecting left scapula which was associated with features of spondylocostal dysostosis.

A linguagem na Síndrome de Treacher Collins: uma análise dialógica / Language in Treacher Collins Syndrome: a dialogical analysis

RESUMO A Síndrome de Treacher Collins ou Disostose Mandibulofacial é decorrente de mutações genéticas e caracterizada por malformações craniofaciais. Crianças com essa síndrome podem apresentar dificuldades cognitivas, linguísticas e psicomotoras. São raras as publicações que discorrem sobre a complexidade de seus aspectos terapêuticos, especialmente, voltados à evolução clínica vinculada à linguagem. O presente estudo objetiva analisar o processo terapêutico voltado à oralidade de um menino com essa síndrome, considerando a natureza dialógica da linguagem. Trata-se de um estudo de caso longitudinal e prospectivo, realizado em uma clínica-escola de uma Universidade, situada no sul do Brasil, durante quatro anos, desde 2012 até 2016. Os dados foram coletados a partir de gravações semanais do paciente em interação com os seus terapeutas, sendo, também, considerados os registros arquivados em seu prontuário. Os resultados indicam que a criança apresentou evolução no que se refere à apropriação da linguagem oral. Apesar das dificuldades na produção vocal e na articulação de fonemas, decorrentes de alterações craniofaciais próprias da síndrome em questão, as atividades dialógicas estabelecidas entre o menino, seus terapeutas e sua família, propiciaram mudanças gradativas no seu posicionamento em relação ao outro e à linguagem. Inicialmente, ele fazia uso de gestos, mímicas faciais, apontamentos, os quais eram compreendidos apenas pelas pessoas que faziam parte do seu cotidiano. Atualmente, além dos recursos gestuais, ele passou a usar a oralidade para participar de práticas interativas, indicando mais autonomia para interagir com seus interlocutores.

ABSTRACT The Treacher Collins Syndrome or Mandibulofacial dysostosis is due to genetic mutations and characterized by craniofacial malformations. Children with this syndrome may present cognitive, linguistic and psychomotor difficulties. There are few publications that discuss the complexity of its therapeutic aspects, especially those focused on language clinical evolution. The present study aims to analyze a speech - language clinical work on oral language of a boy who has this syndrome, considering the dialogical nature of language. This is a longitudinal and prospective case study, carried out in a university clinic located in the south of Brazil, during four years, from 2012 to 2016. Data were collected from weekly recordings of the patient interacting with his therapists, and also from his record files. The results indicate that this child presented oral language appropriation evolution. Despite his vocal production and phonemes articulation´s difficulties, due to his craniofacial alterations that characterize this syndrome, the dialogical activities established between the child, his therapists and his family, caused gradual changes in his language use. Initially, he used gestures, facial mimics, pointing, which were understood only by people who were part of his daily life. Nowadays, he still uses gestures, but he also began to use oral language to participate in interactive practices, which indicates his autonomy to interact with other people.

ABSTRACT Objective: To characterize patients with syndromic craniosynostosis with respect to their neuropsycholinguistic abilities and to present these findings together with the brain abnormalities. Methods: Eighteen patients with a diagnosis of syndromic craniosynostosis were studied. Eight patients had Apert syndrome and 10 had Crouzon syndrome. They were submitted to phonological evaluation, neuropsychological evaluation and magnetic resonance imaging of the brain. The phonological evaluation was done by behavioral observation of the language, the Peabody test, Token test and a school achievement test. The neuropsychological evaluation included the WISC III and WAIS tests. Results: Abnormalities in language abilities were observed and the school achievement test showed abnormalities in 66.67% of the patients. A normal intelligence quotient was observed in 39.3% of the patients, and congenital abnormalities of the central nervous system were observed in 46.4% of the patients. Conclusion: Abnormalities of language abilities were observed in the majority of patients with syndromic craniosynostosis, and low cognitive performance was also observed.

Conclusão: Constatou-se alterações nas habilidades de linguagem na maioria dos sujeitos com craniossinostoses sindrômicas, bem como o baixo desempenho cognitivo.

Implicaciones anestésicas del Síndrome de Parry-Romberg; reporte de un caso / Anesthetic implications of Parry Romberg Syndrome: A case report

Introduction: Parry-Romberg Syndrome is a rare degenerative disease characterized by unilateral atrophy affecting the skin, connective tissue, muscle and bone. The end result is facial asymmetry associated with other skin, dental, visual, cardiovascular, and neurological disorders. Clinical findings, diagnostic evaluation and interventions: The case of a patient with Parry-Romberg Syndrome programmed for frontonasal flap remodeling is discussed. The patient's history includes trigeminal neuralgia, epilepsy, and two previous surgical interventions. Uneventful endotracheal intubation with the Glideoscope® video laryngoscope was performed, upon adequate pre-oxygenation followed by anesthetic induction. Conclusion: The phenotypical characteristics of Parry Romberg Syndrome are severe facial hemiatrophy and craniofacial anomalies that require careful preoperative evaluation and management of a potentially difficult airway. Consequently, the use of video laryngoscopes is a first-line approach. Due to the syndrome's associated disorders, it is essential to maintain hemodynamic stability and prevent any potential seizures.

Introducción: El Síndrome de Parry-Romberg es una enfermedad degenerativa poco común, caracterizada por una atrofia unilateral que afecta la piel, el tejido conjuntivo, el músculo y el hueso. El resultado final es una asimetría facial cursando con otras alteraciones cutáneas, dentales, oculares, cardiovasculares y neurológicas. Hallazgos clínicos, evaluación diagnóstica e intervenciones: Presentamos un caso de un paciente con Síndrome de Parry-Romberg programado para remodelación de colgajo frontonasal. Entre sus antecedentes destacan neuralgia del trigémino, epilepsia y dos intervenciones quirúrgicas previas. Tras una adecuada preoxigenación y posterior inducción anestésica, se realiza una intubación endotraqueal sin incidencias mediante el videolaringoscopio Glideoscope®. Conclusión: El Síndrome de Parry Romberg presenta como características fenotípicas hemiatrofia facial grave y anomalías craneofaciales, que requieren una cuidadosa evaluación preoperatoria y el manejo de una vía aérea potencialmente difícil. Es por esto que los videolaringoscopios resultan una alternativa de primera línea. Debido a sus trastornos asociados, es esencial mantener la estabilidad hemodinámica y la prevención de posibles crisis convulsivas.

Abordagem cirúrgica em paciente portador da disostose cleidocraniana / Surgical approach in patient with dysostosis cleidocranial

A disostose cleidocraniana (DCC) foi descrita e conceituada, pela primeira vez, em 1897, por Marie e Sainton. O padrão de herança é autossômico dominante, porém, em alguns casos, interferências externas no período fetal poderiam causar mutações genéticas, impedindo a transformação de células-tronco mesenquimais em osteoblastos. Essa patologia é caracterizada por malformações cranianas, anormalidades nas clavículas, dentes supranumerários e retenções dentárias. Estudos radiológicos e genéticos são extremamente importantes para o seu diagnóstico preciso. O presente trabalho objetiva apresentar um tratamento cirúrgico dentário em paciente portador dessa patologia.

The Cleidocranial dysostosis (CCD) was described and conceptualized for the first time in 1897 by Marie and Sainton. The pattern of in heritance is autosomal dominant but, in some cases, externalinterference in the fetal period could cause genetic mutation preventing the transformation of mesenchymal stem cells into osteoblasts. This pathologyis characterized by cranial malformations, abnormalities of the clavicles, supernumerary teeth and dental retentions. Radiologicalstudies are extremelyimportanttoa precise diagnosis. Thisstudy aims to present a dental surgicaltreatment in patientswiththispathology.

Disostosis espondilocostal y colangitis aguda en urgencias pediátricas / Spondylocostal dysostosis and acute cholangitis in pediatrics emergency room

Resumen: Introducción: Las malformaciones congénitas vertebrales y costales concomitantes comprenden un grupo heterogéneo de enfermedades denominadas disostosis espondilocostal. Tienen en común la alteración del desarrollo o morfología de las estructuras vertebrales y de la caja torácica con una expresividad variable: desde la deformidad leve sin consecuencias funcionales hasta lesiones que amenazan la vida. Se presenta el caso de una niña con disostosis espondilocostal y colangitis aguda. Caso clínico: Paciente de sexo femenino de 13 meses de edad con desnutrición severa y antecedente de hidrocefalia y mielomeningocele quien ingresa al servicio de Urgencias por presentar dificultad respiratoria progresiva y fiebre. En la evaluación se encontraron malformaciones costovertebrales y colangitis aguda. Conclusiones: Las anormalidades costales complejas consisten en malformaciones de la pared torácica sin un patrón determinado y son extremadamente raras. Cuando se presentan al mismo tiempo que las malformaciones vertebrales, puede considerarse como síndrome de disostosis espondilocostal ligado a herencia autosómica recesiva. El diagnóstico es clínico-radiográfico. La identificación de la disostosis espondilocostal y las complicaciones relacionadas con sus causas genético-moleculares implican un reto para el pediatra y el equipo multidisciplinario que los trata a lo largo de su vida.

Abstract: Background: Congenital malformations of the chest wall comprise a heterogeneous group of diseases denominated spondylocostal dysostosis. They have in common developmental abnormalities in the morphology of the structures of the chest and vertebrae with a broad characterization: from mild deformity without functional consequences to life-threatening injuries. We present the case of a girl with spondylocostal dysostosis and acute cholangitis. Clinical case: A 13-month-old girl with severe malnutrition, history of hydrocephalus and myelomeningocele at birth was admitted in the emergency pediatric room with fever and progressive respiratory distress. Clinical assessment revealed ribs and vertebral malformations and acute cholangitis. Conclusions: Complex rib abnormalities consist in deformities of the chest wall, which do not have a specific pattern and are extremely rare. When they are associated with myelomeningocele and hydrocephalus they may be considered as autosomal recessive inheritance spondylocostal dysostosis. The diagnosis is established by clinical assessment and X-rays. Spondylocostal dysostosis identification and complications related to their genetic and molecular causes are still a challenge for clinical pediatricians and the multidisciplinary medical team who treats these patients throughout lifetime.

Management of obstructive sleep apnea in a Treacher Collins syndrome patient using distraction osteogenesis of the mandible

In this study, we present the surgical treatment of obstructive sleep apnea in a child with Treacher Collins syndrome. A 10-year-old girl with a past history of Treacher Collins syndrome presented to our clinic with her parents for respiratory distress and insomnia. The patient was referred to a sleep laboratory where she was diagnosed with obstructive sleep apnea, which was a consequence of her Treacher Collins syndrome. The patient underwent mandibular distraction osteogenesis under general anesthesia. The mandible was expanded by 15 mm using internal bilateral distractors. After distraction osteogenesis, the patient’s respiratory problems resolved, and she was able to sleep comfortably. Distraction osteogenesis was an effective method of advancing the mandible, increasing the upper airway space and ultimately preventing obstructive sleep apnea syndrome in patients with Treacher Collins syndrome.
