METHOD FOR SURGICAL TREATMENT OF CHRONIC LARYNX STENOSIS OF PARALYTIC ETIOLOGY Russian patent published in 2018 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly to otorhinolaryngology. At first, an incision is made in the skin and subcutaneous tissue on both sides of the larynx parallel to the anterior edge of the sternocleidomastoid muscle at a distance of 0.5–1.5 cm from it. Endoscopic visualization of the larynx is performed. On each side of the larynx, the sternocleidomastoid muscle is moved backward, the front muscles of the larynx are advanced, the posterior third of the lateral plate of the thyroid cartilage is exposed and laryngeal punctures are performed on it from the outside to the inside of the larynx. Then, the first needle is inserted into the point at the intersection of two lines, the horizontal one – at a distance of 0.5–1.0 cm from the lower edge of the thyroid cartilage and the vertical one – at a distance of 0.5–1.0 cm from the lateral edge of the thyroid cartilage. And the second needle is inserted at a point at a distance of 1.0–1.5 cm proximal to the point of insertion of the first needle. Further, the needles and then the threads are advanced into the cavity of the larynx and taken out of the wound on the opposite side of the neck. Then, the filaments are cut in the laryngeal cavity and are tied up in pairs, immersing the vocal cords in the submucosal layer. Lateralization of the vocal cords is performed bilaterally, and the filaments are fixed on the lateral plate of the thyroid cartilage on both sides.

EFFECT: method allows to increase the efficiency of the operation, reduce the trauma, the risk of intra- and postoperative complications, reduce the time of rehabilitation by creating a stable lumen of the larynx, sufficient to restore respiratory function without impairing the protective function.
