[Genetic aspects of congenital pathology of the larynx and trachea].

Medical-genetic examination covered 24 families of patients with congenital defects of the larynx and trachea. These developmental defects can be attributed to multiple unestablished defects (66.7%) or can be part of some congenital-hereditary syndromes (25%) such as chromosomal, genetic, teratogenic, of unknown etiology. The percentage of isolated developmental laryngeal and tracheal defects is relatively small--8.3%.
