Transseptal repair of unilateral choanal atresia

Unilateral choanal atresia is a congenital problem initially observed by the otolaryngologist as unilateral nasal obstruction. Elective surgical correction can be done using the transnasal, transpalatal, transantral, or transseptal techniques. Two patients underwent this procedure with the transseptal technique. We believe this is a safe, uncomplicated, and reliable technique for the correction of unilateral choanal atresia.
