Summary

Congenital choanal atresia is an abnormality of the posterior nasal passages resulting in complete or partial obstruction of the nasal airways. It has an incidence of 1: 5000 to 8000 live births, with a female predominance. 41% - 72% occur in conjunction with non-syndromic facial abnormalities such as arched palate, cleft lip, and auricular deformities. About 4% present as a component of chromosomally-based syndromes such as (coloboma, heart defect, atresia choanae, retarded growth, genital abnormality, and ear abnormality" and Treacher Collins syndromes.

Previous reports have described the ratio of bony to membranous choanal atresia as 9:1. However, a detailed review of computed tomography study combined with histopathological studies has shown mixed bony-membranous atresia in about 70% of cases and purely bony atresia in 30% of cases.
