Hystoanatomical structure of laryngeal ventricles

The laryngeal ventricles are paired fusiform fossae located between the vestibular and true vocal cords. In another way they are called laryngeal sinuses or Morgagni's sinuses. The few available literature data contain only elements of the histological structure and functions of the laryngeal sinuses. Thus, it is known that the laryngeal ventricles act as a resonator in voicing, and the largest amount of laryngeal secretion is produced here, which, apparently, performs a protective function. The authors of this article present the results of their own study of the histological structure of the laryngeal ventricles, conducted at the Bureau of Forensic Medical Examination in Bishkek on preparations obtained from 56 corpses of both sexes aged 18 to 70 years who did not have laryngeal pathology during their lifetime. It has been established that the accumulation of glands, lymphoid tissue, collagen and elastic fibers and nerve endings is concentrated in the laryngeal ventricles. A tendency towards age-related involution of the glandular apparatus was also revealed.
