Forty-eight cases of congenital bony posterior choanal atresia are reviewed revealing a 64% incidence of unilateral atresia with no correlation existing between sex and side of involvement. Bilateral atresia presents soon after birth with respiratory problems whereas feeding difficulties and nasal discharge are the predominant features of unilateral atresia. Other congenital anomalies existed in 48% with 82.5% being major or multiple. The implications of this are discussed. Early surgical repair is advocated. Transpalatal and endonasal approaches yield initial success rates of 57% and 59% respectively with similar frequency of subsequent dilatations being necessary in the initial failure groups to obtain long-term success. Regular prophylactic bougienage by the parents does not appear to alter the outcome significantly.
回顾了48例先天性骨性后鼻孔闭锁病例，发现单侧闭锁发生率为64%，性别与受累侧别之间无相关性。双侧闭锁在出生后不久即出现呼吸问题，而喂养困难和鼻分泌物是单侧闭锁的主要特征。48%的病例存在其他先天性异常，其中82.5%为严重或多发异常。文中讨论了其影响。提倡早期手术修复。经腭和鼻内入路的初始成功率分别为57%和59%，初始失败组为获得长期成功所需的后续扩张频率相似。家长定期进行预防性探条扩张似乎不会显著改变结果。
