CT-assisted surgery in choanal atresia.

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.
