Measurements of pre- and postpubertal human larynx: a cadaver study.

This study investigates the differences in proportion and structure of the larynx in both children and adults, as well as changes which the larynx undergoes during puberty and adolescence. Furthermore, we have tried to answer the question on the existence of laryngeal sexual dismorphism in pre-pubertal (or pubertal) children. Larynges of 20 adults (10 men and 10 women) and 34 larynges of children not more than 12 years of age were acquired from the Forensic Medicine Department of the Medical University of Warsaw, Poland.
