Abstract

  Choanal atresia remains a challenge for the otolaryngologist. Restenosis may still occur post surgery and represents unsuccessful treatment. Current surgical endoscopic techniques still have a failure rate of around 15 percent. A more effective technique presenting lower rates of restenosis is necessary. This paper describes a new technique that may be more effective by using a reversal flap in the posterior septum. The authors provide a step-by-step description of this new procedure. The reversal flap covers the exposed bone surface with mucosa, which can prevent stenosis and contribute to a better healing process. The authors believe that by avoiding the raw area in the posterior septum, stenosis recurrence may be reduced and therefore recommend considering this technique for more effective treatment of choanal atresia.
