TRANSNASAL ENDOSCOPIC TREATMENT OF CHOANAL ATRESIA

Abstract: To evaluate the outcome of the repair of congenital choanal atresia (CCA) using the transnasal endoscopic approach with and without power instruments.This study was done on Eight patients with either unilateral or bilateral congenital choanal atresia were treated using the transnasal endoscopic approach. We describe our experience and follow-up of 8 patients (6 with unilateral atresia and 2 with bilateral atresia 1) that were treated with the use of the transnasal endoscopic technique during a 5-year period. In 5 patients, the transnasal endoscopic technique was performed using conventional biting instruments, and in 3 patients, the transnasal endoscopic technique with power instruments was used. No stent were used. Results: Of 8 patient procedures, 6 remained patent. One patient required minor debridement of granulation tissue 1 week and 1 patient had restenosis and revision done in 1 month.
