Congenital choanal atresia occurs once in 7,000 to 8,000 births. The atresia is bony in most cases, more common in females, and more often right-sided in patients with unilateral atresia. The incidence of associated congenital anomalies is relatively high. During the 25-year period 1951 to 1976, 36 patients with choanal atresia were treated at the Mayo Clinic; 19 were females and 17 were males. The ages at the time of surgical treatment ranged from 1 day to 58 years. Twenty-four patients had unilateral obstruction, and 12 had bilateral obstruction. Six patients (17%) had other associated congenital anomalies. Intranasal perforation and transpalatal correction were most commonly employed in children who were less than 8 years old, and transseptal correction was most often carried out in older patients. The nature of the stenting material and the age of the patient have important bearing on the outcome of the operation. Congenital choanal atresia is a bony or membranous closure of the posterior choana. It may be complete or incomplete and unilateral or bilateral. We wish to report on a series of children and adults who were treated for congenital choanal atresia at the Mayo Clinic during a 25-year period and to describe a transseptal method of correction that may be performed concurrently with septal reconstruction and external nasal surgery in older children and adults.
