title: [Bilateral bony choanal atresia in an adult].
abstract: A case of 17-year old male, complaining of long term nasal obstruction is presented. Endoscopic nasal exploration showed a bilateral bony choanal atresia, confirmed by TC scan. Bilateral choanal atresia in newborns is a life-threatening malformation. The urgency management includes, first of all, the establishment of a sure orotracheal airway and a delayed surgical correction. A few instances do not produce an acute respiratory distress in newborns and failed to be diagnosed until nasal obstruction develops other symptoms in adult life.
