METHOD OF TREATING CHRONIC NEUROGENIC STENOSIS OF LARYNX Russian patent published in 2021 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly to otorhinolaryngology. Endoscopic approach with an external approach is performed, a laryngeal lumen is enlarged. Vexed muscle is resected on both sides together with the auger's process of the arytenoid cartilage by means of a microdebroder. If enlarging a laryngeal lumen, first, one side is incised, on one side, on an upper surface of a mucous membrane of a vocal fold with size of 3.0 mm, at distance of 1.5 mm from its anterior end. Microdermander cutter is inserted into the incision and the larynx elements are removed submucosally. Microdermander cutout is placed along the vocal fold, a portion of the anterior portion of ary-feet cartilage is resected - an arched comb, a knoll, an apex, while maintaining a rear surface of a auroral chrysotile. Then, after performing similar actions on the other side, one nodal suture is applied on incisions of the mucous membrane of the right and left vocal folds. After larynx expansion into its lumen, a stent is installed. Stent is positioned so that its lower end is in the projection of the first tracheal ring, and the upper end is located in the vestibular segment of the larynx. Stent is then fixed in the laryngeal cavity, pressing the mucosa in the points of the removed vocal muscle and the arytenoid cartilage fragments. Stent is removed three days after the operation.

EFFECT: method enables higher effectiveness of the operation by reducing traumatization of the laryngeal mucosa and a risk of developing intraoperative and postoperative complications when forming a stable laryngeal lumen sufficient for recovering the respiratory function.
