Congenital Choanal Atresia is a relatively uncommon anomaly. Among various surgical approaches for treating this ailment
that have been proposed to date, transpalatal and transnasal endoscopic approaches are the preferred methods for surgical
treatments. Because restenosis is the most important post-surgical concern, some authors used topical application of mitomycin
C in the choanal atresia and found it to be effective in the prevention and treatment of scar formation. We have experienced a
case of right membranous choanal atresia and left membranous choanal stenosis which were treated with a transnasal endoscopic
approach using powered instrumentations and topical application of mitomycin C without an application of prolonged
stent. Eight months after the treatment, patent neochoanae remains without evidence of restenosis.
