To limit restenosis after surgical repair of choanal atresia.
A total of 20 children (age range 3 days to 11 years) with choanal atresia underwent surgical repair using a microdebrider via an intranasal approach. Surgery was guided by CT. Mitomycin was administered at the end of the procedure.
An average of 1.7 procedures per child were required. CT combined with peroperative endoscopy revealed postoperative neo-osteogenesis and insufficient bone resection.
CT-assisted intranasal repair led to extended bone resection of the atretic plate, the predominant cause of which was restenosis resulting from neo-osteogenesis.
限制后鼻孔闭锁手术修复后的再狭窄。
共有20例后鼻孔闭锁患儿（年龄范围3天至11岁）通过鼻内入路使用微型清创器进行手术修复。手术由CT引导。术中结束时给予丝裂霉素。
每名患儿平均需要1.7次手术。CT结合术中内镜检查显示术后新骨形成和骨切除不足。
CT辅助鼻内修复导致闭锁板的骨切除范围扩大，其主要原因是新骨形成导致的再狭窄。
