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.
