ABSTRACT
Introduction: Congenital choanal atresia is an imperfection on the development of communication between the posterior nasal cavity and the nasopharynx. The incidence is 1:5,000 to 1:8,000 live births. It is usually unilateral and in females. Objective: To describe the epidemiology, the clinical symptoms and the main surgical accesses for correction of choanal atresia from the case report. Case Report: 35-year-old female patient, presenting bone bilateral choanal atresia. The diagnosis was performed through CT and nasal endoscopic. Patient was treated by transnasal endoscopic surgical technique associated with transeptal access. It was performed a mucoperiosteal flap rotation covering the sidewall of the new choana. Topic use of mytomicin was performed, but there was no use of stents. Conclusion: In our experience, the transnasal access endoscopic is the choice for surgical correction of the congenital choanal atresia. In the cases where there is important thickness of the posterior portion of the vomer, the transeptal access can be associated with the transnasal. There is no need of stents use after surgery, if a mucous flap re-covering the new choana is made.
