Abstract

Posterior choanal atresia is thought to result from a failure of rupture, between the 35th and 38th day of foetal life, of the partition which separates the bucco-nasal and bucco-pharyngeal membranes (Williams 1971). The choanal atresia which results may be unilateral or bilateral, bony or membranous, complete or incomplete. The bony atresia is commonly located 1–2 mm anterior to the posterior margin of the hard palate; the membranous form usually occurs more posteriorly. In approximately one third of patients the atresia is bilateral, and some patients have associated deformities including a high arched palate and increased thickness of the vomer and nasal septum. A familial incidence has been described by some authors (Wilkerson and Coyce 1948).
