Choanal atresia: How useful is computed tomography.

Computed tomography (CT) has recently been hailed as the most useful tool in the diagnosis and management of congenital posterior choanal atreasia. Our study of 11 patients with posterior choanal atresia by CT does not seem to confirm this claim. CT, which demonstrates very clearly all the anatomical details of the region, does not appear to play any major role in the diagnosis of the condition; nor in the planning of the management of patients in whom posterior choanal atreasia is the only major craniofacial abnormality.
