[Bilateral choanal atresia in the newborn. Recommended management apropos of 1 case observed in Lomé, Togo].

The bilateral choanal atresia is a neonatal emergency. Its diagnosis is easily evoked when faced with a respiratory distress and cyanosis. It is quickly confirmed by a nasal optic endoscopy or when a nasopharyngeal aspiration catheter is held up by an obstacle. Putting a pharyngeal Mayo's cannula is an urgent gesture. The treatment uses transnasal perforation of the septum followed for two months with frequent aspirations.
