Abstract

OBJECTIVE: To limit restenosis after surgical repair of choanal atresia. MATERIAL AND METHODS: 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. RESULTS: An average of 1.7 procedures per child were required. CT combined with peroperative endoscopy revealed postoperative neo-osteogenesis and insufficient bone resection. CONCLUSIONS: CT-assisted intranasal repair led to extended bone resection of the atretic plate, the predominant cause of which was restenosis resulting from neo-osteogenesis.
