ObjectiveThe purposes of this study were to report our experience with endoscopic treatment of choanal atresia (CA), to illustrate our surgical technique and analyse the different factors that may affect outcomes.Material and methodsA retrospective review was performed of patients affected by congenital CA and treated between June 1996 and November 2013 at three referral centres which follow a uniform policy.ResultsEighty-four patients with CA (55 unilateral and 29 bilateral), aged between one day and 76 years (mean, 13 years) were included. Associated malformations were present in 28 patients. The overall success rate was 93%, with 96.3% and 86.2% success rates for unilateral and bilateral CA respectively. Six patients (7%) required revision surgery for early symptomatic restenosis. Statistical analysis revealed that outcomes were not influenced by sex, previous surgeries, unilateral versus bilateral atresia or associated anomalies. However, age seemed to be a prognostic risk factor for patients under one year-old.ConclusionThe endoscopic endonasal approach is safe and effective, with a very high success rate and low morbidity. The removal of the vomer and the use of mucoperiosteal flaps are the main keys to avoiding postoperative stenosis. The use of stents or Mitomycin C is therefore not mandatory.
