The study of anatomometrical characteristics and macromicroscopical structure of larynx was carried out with the use of classical morphological methods. The materials for the study were larynges of 33 male (45,5%) and female (54,5%) cadavers of children and junior age without pathology of neck organs and respiratory apparatus. It was determined that during the first year of life the intensity of size increment of larynx had different dynamics for parameters which characterized vertical and frontal sizes. At junior age the anatomometric characteristics of larynx approximate to similar parameters for people of mature age, pronounced sex and individual differences appear. Age-related differences in the anatomic characteristics of cartilages consist of relief, form and size changes. Age-related differences in the sequence of formation of the spots where larynx muscles originate and attach were discovered. Age-related changes in the structure of joint were only related to their size augmentation at the expense of the growth of articular surfaces. Individual differences appear at junior age, they are connected with appearance of asymmetrical nidi of ossification at the inferior horns of thyroid cartilage.
