Abstract:
Diseases diagnosis of the larynx in children and adults remains a difficult and urgent task of otorhinolaryngology. Modern diseases diagnostics of the larynx is based on endoscopic examination methods, which are the most informative and allow assessing the status of the larynx at a very advanced level. In 397 patients (329 adults and 68 children) with dysphonia, video rhinopharyngolaryngoscopy was performed using the PENTAX Medical VIVIDEO system. In addition, in 36 adults and 8 children, the status of the larynx was assessed by video laryngoscopy and video laryngostroboscopy using a rigid endoscope. Comparative analysis of video rhinopharyngolaryngoscopy and video endolaryngoscopy usage showed that the quality and size of the video image of the larynx in adults and children when using a video rhinopharyngolaryngoscope are comparable to the picture obtained using a rigid endoscope. The use of a video rhinopharyngolaryngoscope increases the efficiency of the examination, since the small diameter of the inserted working part allows carrying out the procedure as fast and comfortably as possible for the patient.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
