Congenital choanal atresia (CA) is relatively rare, with an incidence of 1 in 7,000 births with a majority being the mixed bony-membranous type. There are 5 described methods of CA repair: transpalatal, transnasal, sublabialtransnasal, transantral, and transseptal approaches. Transpalatal and transnasal have been the most popular in the last several decades with transnasal becoming the preferred technique with the advent of endoscopic instruments and techniques. In this chapter, the authors seek to describe their techniques for endoscopic transnasal repair of CA including surgical pearls for success.
