[Congenital malformations of nose and paranasal sinuses].

410 patients with malformations of the external ear or nasal cavity were examined. Basing on this evidence, clinical and diagnostic aspects of agenesias, hypogenesias, hypergenesia, dysgenesia, persistence and dystopias of the nose and intranasal structures are analyzed. Both severe and "minor" anomalies are considered. Endoscopic diagnosis of the malformations is described.
