title: [Classification of congenital defects of larynx].
abstract: A classification of congenital malformations of the larynx was developed on the basis of 61 observations. All the malformations were subdivided into organ (20 cases) and tissue (41 cases) defects. Organ congenital malformations of the larynx included: dysgenesis of the cartilage stroma, dystopia, and vascular lesions. Tissue congenital malformations of the larynx included: dysplasia, hypoplasia, and dyschronia. The most severe form of organ malformations was dysgenesis of the cricoid cartilage that required surgical intervention in all cases. The most frequent form of tissue malformations was dysplasia (24 cases) of connective, cystic (polypous), or mixed type. Every form of congenital malformations of the larynx are described, and their specific features and prognosis are discussed.
