Unilateral Choanal Atresia - Presentation in Varied Age Group S

Abstract

ABSTRACT:Choanal atresia is an uncommon and poorly recognized cause of unilateral nasal obstruction in adults. We discuss here two cases of unilateral choanal atresia, one adult and a child. Both of them had nasal obstruction as their chief complaint. Both patients underwent a Trans nasal endoscopic excision of choanal atresia with assistance of powered instrument and repair of the choana with stent. Both the patients were followed up regularly for a period of one year and were found to be symptom free with a well healed and patent choana. These case reports highlight the possibility of considering choanal atresia as a differential diagnosis in all patients presenting with unilateral nasal obstruction. CT scan and Nasal endoscopy are the investigations of choice. Trans nasal endoscopic approach with stenting provides an excellent method of management.
