[Endoscopic treatment for choanal atresia].

Choanal atresia is an infrequent congenital malformation. Classically, 4 surgical approaches have been described for its treatment: transnasal, transpalatal, trans-septal, and transantral. Of these, transpalatal was preferred. In recent years, the progress in nasal endoscopy has led to reconsideration of the transnasal route as being less invasive and providing excellent results. The use of stents to prevent re-stenosis is a controversial issue. However, the application of substances such as mitomycin may offer decreased need for stenting by reducing the development of cicatrix tissue. We report the case of a patient with bilateral choanal atresia and its surgical treatment using nasal endoscopy with topical mitomycin.
