내시경과 Nd-YAG Laser를 사용한 선천성 후비공폐쇄의 치료

Choanal atresia is a congenital anomaly usually diagnosed at birth. The transnasal endoscopic route offers excellent visualization of the posterior choana, so the ability to open the defect widely with a high surgical success rate. Recently we have treated a case of unilateral membranous type using Nd：YAG laser. The advantage of the Nd：YAG laser is its fiber-optic delivery, allowing the laser to be hand-held, giving greater precision. Laser ablation of the obstructing tissues was attempted through a videoendoscope. The procedure was found to be safe, quick, with minimal morbidity and a shorter in-patient stay. Good nasal airway was achieved. We present the result of the transnasal endoscopic approach using Nd：YAG laser with review of literature. (J Clinical Otolaryngol 1999;10:87-89)
