Abstract

AbstractIntroductionChoanal atresia (CA) is a congenital narrowing or obliteration of the posterior nasal aperture. The condition is rare with an incidence of approximately 1 in 5000 to 9000 live births.ObjectiveThe aim of this work was to assess the results of treating this condition at the Otolaryngology Department in Oslo University Hospital‐Rikshospitalet.MethodsRetrospective review of patients treated at Oslo University Hospital‐Rikshospitalet between 2005 and 2015 were performed. The review consisted of surgical techniques and outcomes, types of atresia, uses of stent and mitomycin C, age at operation, laterality of atresia, and associated anomalies.ResultsThirty‐one patients with CA were referred to Oslo University Hospital‐Rikshospitalet during the mentioned observation period. Nine (29%) of the cases had bilateral CA and 22 (71%) had unilateral CA. Ten patients (32%) had bony atresia, 12 (39%) had membranous and eight (26%) had mixed type of atresia. Twenty‐one patients (68%) needed revision surgery because of complete or partial restenosis after primary surgery. Stents were applied in 16 cases (52%) of patients and Mitomycin C was only used in the primary surgery of three patients. In the bilateral group, eight of the nine patients were operated on within the first 9 days of life. Sixteen patients (45%) had associated anomalies.ConclusionsAccording to the observations in our sample, the restenosis problem is expected more and may need more revisions in bilateral CA than the unilateral type. The presence of other anomalies is associated with higher incidence of restenosis. Stenting is not essential in preventing restenosis.
