    Abstract:
    OBJECTIVE: To analyze prognostic factors in the management of patients with choanal atresia. STUDY DESIGN: This is a review of 114 patients operated on for choanal atresia in a tertiary care center between November 1986 and November 2016, including clinical characteristics, surgical management, and postoperative course with final nasal patency. The data were collected in a database that was updated over time. RESULTS: Among the 114 patients, 78 were female, 77 presented with unilateral choanal atresia, and 37 presented with bilateral unilateral choanal atresia, corresponding to 151 nasal fossae. Forty-seven patients had associated abnormalities (41.2%), including CHARGE, diagnosed in 20 children (17.5%). At the end of follow-up, 91 patients (79.8%) had normal choanal patency. The identified risk factors of surgical failure were age <6 months (P = .004), weight <5 kg (P = .007), and bilateral choanal atresia (P < .001). The type of atresia, presence of associated abnormalities, surgical approach, stenting, and use of mitomycin were not significantly linked with the surgical results. CONCLUSIONS: This series highlights the importance of the timing of surgery, which is guided by the clinical ability of the infant to tolerate the procedure. Endoscopic approaches are widely performed, but a transpalatal approach, necessary in some cases of bilateral choanal atresia, does not alter the results. Unilateral choanal atresia surgery should be delayed after age 6 months and/or weight >5 kg when possible.
