The purpose of this study was to investigate the severity of presenting symptomatology in patients with unilateral choanal atresia and to assess the surgical results of patients undergoing transnasal endoscopic repair. A retrospective review of all patients with choanal atresia presenting to the author between 1990 and 1997 was performed, identifying 13 patients with unilateral choanal atresia. These patients were analyzed with respect to presenting symptomatology, preoperative computed tomography scans, appearance, type of surgical repair, and surgical results for patients undergoing endoscopic transnasal repair. Eleven patients underwent successful endoscopic transnasal repair, one patient underwent conversion to transpalatal repair after an unsuccessful attempt at transnasal endoscopic repair and one patient underwent a planned transpalatal repair. Eleven patients who underwent repair by transnasal endoscopic technique have all done well with follow-up ranging from 3 months to 7 years. Although the symptomatology of unilateral choanal atresia is not as dramatic as bilateral choanal atresia, significant airway symptomatology may be present, especially in children presenting at a very young age. It appears that transnasal repair of unilateral choanal atresia is an excellent treatment modality with excellent postoperative surgical results.
本研究的目的是调查单侧后鼻孔闭锁患者出现症状的严重程度，并评估接受经鼻内镜修复手术患者的手术效果。对1990年至1997年间向作者就诊的所有后鼻孔闭锁患者进行了回顾性研究，确定了13例单侧后鼻孔闭锁患者。对这些患者的症状表现、术前计算机断层扫描、外观、手术修复类型以及接受内镜经鼻修复患者的手术效果进行了分析。11例患者成功接受了内镜经鼻修复，1例患者在经鼻内镜修复尝试失败后改行经腭修复，1例患者接受了计划性经腭修复。11例接受经鼻内镜技术修复的患者在3个月至7年的随访中情况良好。尽管单侧后鼻孔闭锁的症状不像双侧后鼻孔闭锁那样明显，但可能存在明显的气道症状，尤其是在年龄很小就出现症状 的儿童中。看来，单侧后鼻孔闭锁的经鼻修复是一种极好的治疗方式，术后手术效果极佳。
