BILATERAL bony atresia of the choana is encountered so infrequently that its diagnosis is often overlooked. The purpose of this paper is to suggest a simple surgical method of managing the choana patent postoperatively and preventing atresia. The subject of choanal obstruction has been so extensively discussed by Beinfield1 and Dolowitz and Holley2 in recent articles that I shall omit extensive bibliography and discussion of anatomy, embryology, and etiology. I shall concentrate on reporting the history of a patient who had a congenital bilateral osseous choanal obstruction, the simple operative procedure for its removal, and the attempt to restore patency and normal nasal respiratory physiology. Three modes of operative approach were considered for the surgical treatment of the obstruction of both posterior nasal orifices: (1) transpalatal; (2) transseptal, by performing a submucous resection of the septum, including the perpendicular plate of the ethmoid, and removing the posterior, or
