EVALUATION OF EFFECTIVENESS OF THE LASER ENDOSCOPIC LARYNGOPLASTY IN PATIENTS WITH CHRONIC PARALYTIC STENOSIS OF THE LARYNX

Chronic stenosis of the larynx (CSL) is a group of diseases which is the main symptom of is persistent narrowing of the larynx lumen, disrupting the flow of air into the respiratory tract, leading to the development of obstructive respiratory failure, as well as pronounced impairment of the voice function. One of the types of stenosis is paralytic stenosis of the larynx (PSL), in which the narrowing of the larynx lumen is associated with a disorder of motor function in the form of a decrease in the strength/amplitude of voluntary movements (paresis) or their complete absence (paralysis) due to a violation of the innervation of the corresponding muscles of the larynx.
