Abstract
A transnasal approach was employed in 28 neonates (26 blacks and 2 whites) with bilateral choanal atresia. In each patient the atresia was perforated microsurgically with the drill, followed by insertion of a Portex endotracheal tube for a period of three months. By this method a satisfactory nasal respiration was established immediately. Removal of the posterior part of the vomer is crucial to the successful result. During the follow-up, one death was recorded in a microcephalic neonate, unrelated to the operation and another four patients required repositioning of the tube under general anesthesia. We feel that the above technique is simple and definitive with negligible complications.
