[Transnasal endoscopic repair of choanal atresia]

We evaluated the results of endoscopic repair for choanal atresia.Ten patients (2 males, 8 females) underwent transnasal endoscopic repair for choanal atresia. Involvement was unilateral in five cases and bilateral in five cases. Unilateral patients were treated at a mean age of 22.6 years (range 1 to 44 years), while bilateral cases were treated within the first six days of life. Two patients with bilateral involvement had associated polydactyl and tracheoesophageal fistula, respectively. The mean follow-up period was 26 months (range 8 to 56 months).No postoperative complications such as significant hemorrhage, injury to the skull base, cerebrospinal fluid fistula, septal perforation, or granulation tissue formation were encountered. All the patients had choanal patency at the end of six months.Endoscopic repair of choanal atresia is effective in both unilateral and bilateral cases.
