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. Methods used are based on (1) anatomical preparation, (2) anatomical description and (3) measurements performed with the use of a digital camera and a computer-aided system MULTISCAN. Statistics, the Student's test and Pearson's linear correlation coefficient were calculated. Results show that proportions of the larynx depend on the age of the individual. The younger the individual is the more slender the larynx would be. However, proportion is not gender-related and hence is about the same in both males and females of any given age-group. Nevertheless, basic parameters were larger in males.

It is rare to encounter exceptional individuals such as Ludwik Maurycy Hirschfeld. He was born into poverty and early on discovered his passion for medicine, particularly anatomy. His life is a testament to what pure human determination can achieve. He overcame societal and financial obstacles, ultimately becoming a physician, anatomist, and scientist. In 1834, Hirshfeld left Poland for France. His first exposure to medical anatomy came while under the direction of the great anatomist Professor Bourgery at Ecole Pratique de Médicine. In 1848, he earned his degree in medicine and published his work "Des injections capillaires." He coupled his love of anatomy with teaching and research. Hirschfeld's skills, as a dissector, enabled him to prepare specimens for illustration, which produced some of the anatomy atlases of modern times. "The Descriptive Anatomy of the Human Body" is one of his most influential works. Dr. Hirschfeld pioneered the initial illustrations of the meninges of brain. There are many anatomical structures named after him, including Hirschfeld's nerves and anastomoses. Hirshfeld remained as a professor until 1875. His death in 1876 was a great loss to the scientific community. His scientific accomplishments were astounding but he should also be remembered as a great humanitarian, an individual who offered medical treatment to the poor, and who strived to instill in his students a passion for anatomy.
