Bilateral Choanal Atresia in 34 Year-old Patients

Summary

Introduction: Choanal atresia (CA) can be defined as a failure to develop the communication between the nasal cavity and nasopharynx. May occur as a plate osteo-membranous, bony or membranous. Diagnosis depends on high clinical suspicion and laboratory tests, treatment is surgical.

Objective: To report a case of an adult patient diagnosed with bilateral choanal atresia and underwent surgery.

Case Report: MLSM, 34 years old female with a history of bilateral nasal obstruction, rhinorrhea hyaline since childhood. On nasal endoscopy and CT scan of the sinuses showed bilateral membranous atresia osteo. Patient underwent endoscopic transnasal route, with production of mucosal flap covering the wound, without stent placement. Tomography was performed which showed control choanae open and broad. The patient progressed well and has normal nasal breathing.

Conclusion: AC bilateral, although rare, can occur in adult patients.

Resumo

Introdução: A atresia de coanas (AC) pode ser definida como a falha no desenvolvimento da comunicação entre a cavidade nasal e a nasofaringe. Pode ocorrer como uma placa ósteo-membranosa, óssea ou membranosa. O diagnóstico depende de alto grau de suspeição clínica e exames complementares, o tratamento é cirúrgico.

Objetivo: Relatar um caso de uma paciente adulta com diagnóstico de atresia coanal bilateral e que foi submetida a tratamento cirúrgico.

Relato do Caso: MLSM, 34 anos,sexo feminino, com história de obstrução nasal bilateral, rinorreia hialina desde a infância. Na endoscopia nasal e Tomografia Computadorizada de seios da face evidenciou atresia ósteo-membranosa bilateral. Paciente foi submetida a tratamento cirúrgico endoscópico via transnasal, com confecção de retalho mucoso cobrindo a área cruenta, sem colocação de stent. Foi feito Tomografia de controle que evidenciou coanas abertas e amplas. Paciente evoluiu bem e apresenta respiração nasal normal.

Comentários Finais: A AC bilateral, embora rara, pode ocorrer em pacientes adultos.
