Introduction: Choanal atresia (CA) is a rare congenital blockage of the posterior nasal orifices. The aim of this work is to perform a retrospective study of patients guided in HP-CHC (Pediatric Hospital of Coimbra Hospital Center), to characterize the group of children treated, evaluate the results by comparing them with the literature, as well as analyze possible predictors failure.
Methods: Retrospective study of nine children treated between August 2005 and August 2010.
Results: In epidemiological terms, five patients were female and four male. We found five bilateral cases and four unilateral, all right. Regarding the type of obstruction, seven cases were mixed type and two were bone type. We found an association to Charge Syndrome and another to Treacher- Collins Syndrome. The age at the time of surgery ranged from 6 to 28 days in bilateral cases and from 4 to 8 years in unilateral cases. The surgical technique performed was transnasal, using silastic stent and mitomycin C aplication. Follow-up was conducted in a fortnightly, with progressive spacing. We found three recurrences, requiring surgical intervention.
Conclusions: This is a rare condition, and our epidemiological and interventional results have similarities with other literature. Our study suggests to the early age at the time of intervention as a predictor of restenosis.
