ABSTRACT

Treacher Collins também chamada de disostose mandibulofacial, é uma alteração genética dominante rara caracterizada pela má-formação dos ossos e tecidos da face. É uma síndrome crânio-facial que apresenta alterações bilaterais e simétricas de estruturas originadas do primeiro e segundo arcos branquiais. A maioria dos casos possui transmissão autossômica dominante e expressividade variável. O objetivo do presente estudo é realizar um relato de caso sobre o impacto do tratamento odontológico na qualidade de vida do paciente portador de Treacher Collins. Paciente, 39 anos, sexo feminino compareceu a uma clínica odontológica em Belo Horizonte, com a queixa principal de falhas dentárias e sensibilidade. Durante a anamnese a paciente relatou ter a STC, durante o exame clínico extraoral verificou a presença de hipoplasia malar e mandibular, malformação dos pavilhões auriculares com perda auditiva, obliquidade e coloboma palpebral inferior. Ao exame intraoral observou ser classe II de Angle, ausência dos dentes 11, 12, 13, 21 e 22 e extrusão do dente 41 e recessão gengival e periodontite estágio I grau A. Após exames de periodontograma e complementares foi realizado uma raspagem nas áreas com profundidade de sondagem maior que 3mm, frenectomia labial inferior, aplicação de laser para sensibilidade, enxerto gengival e colocação de prótese parcial removível. A paciente ao final do tratamento relatou ter se sentido realizada e contente com a sua conclusão, ela foi encaminhada ao Sistema único de Saúde para realizar as cirurgias para corrigir as alterações crânio-faciais. O tratamento odontológico deve ser adaptado a cada indivíduo de acordo com sua necessidade, tendo uma abordagem multidisciplinar, possibilitando uma melhora na qualidade de vida e estética do paciente(AU)


Treacher Collins syndrome is a rare dominant genetic disorder characterized by malformation of the bones and tissues of the face. It is a craniofacial syndrome that presents bilateral and symmetrical alterations of structures originating from the first and second branchial arches. The aim of the present study is to perform a case report on the impact of dental treatment on the quality of life of a patient with CTS. Patient, 39 years old, female, attended a dental clinic in Belo Horizonte, with the main complaint of dental flaws and sensitivity. During the anamnesis the patient reported having CTS, during the extraoral clinical examination she verified the presence of malar and mandibular hypoplasia, malformation of the pinnae with hearing loss, obliquity and lower eyelid coloboma. Intraoral examination revealed Angle class II, missing teeth 11, 12, 13, 21 and 22, extrusion of tooth 41, gingival recession and stage I periodontitis grade A. After periodontogram and complementary exams it was performed a scaling in areas with a probing depth greater than 3mm, lower lip frenectomy, laser application for sensitivity, gingival graft and placement of partial removable prosthesis. The patient at the end of treatment reported feeling fulfilled and happy with its completion, she was referred to the Unique Health System to undergo surgery to correct the craniofacial changes. The current treatment aims at functional and aesthetic correction and the need for psychosocial support, having the joint participation of a multidisciplinary team to achieve this goal(AU)

ABSTRACT

Treacher Collins syndrome (TCS) is the most common and well known mandibulofacial dysostosis with characteristic clinical features including downward slanting of palpebral fissures, coloboma of the lower eyelid, hypoplastic zygomatic arches, micrognathia, macrostomia, microtia, and other deformities of the ears. TCS is caused by mutations in at least 3 genes involved in pre-rRNA transcription: TCOF1, POLR1D and POLR1C. We experienced a 1-day-old female infant with characteristic clinical features of TCS. A novel, heterozygotic mutation within the TCOF1 gene (c.3874_3875insG, p.Ala1292Glyfs*30) was identified to cause a premature stop codon.
