METHOD FOR RECONSTRUCTION OF ANTEROLATERAL LARYNX AND CERVICAL TRACHEA IN PATIENTS WITH EXTENDED LARYNGOTRACHEAL OBLITERATION OF THE LUMEN Russian patent published in 2023 - IPC A61B17/24 

FIELD: medicine; surgery; otorhinolaryngology.

SUBSTANCE: before the operation, the required number of allografts from demineralized bone tissue is kept in saline for 10 minutes. Then they are given a rectangular shape with rounded edges. In this case, the size of allografts is selected individually depending on the extent of the defect. Finished allografts are perforated with through holes. Then, during the operation, after excision of the scar tissue, a new lumen of the larynx and trachea is formed. In the area of stenosis, form the inner lining of the anterior wall of the trachea. Muscular-fascial pockets are formed paratracheally, where the required number of allografts is placed and set in a vertical position. They are fixed to the surrounding tissues with vicryl 3.0, covered in layers with muscles, fascia, subcutaneous fat and skin. Then carry out prosthetics on a T-shaped tracheostomy tube from 3 to 6 months. The control period is carried out without a tracheostomy tube with a hermetically sealed laryngotracheostomy opening. With a favorable course of the control period: maintaining the supporting function of the walls of the laryngotracheal complex with allografts, in case of absence of a rejection reaction and material migration, absence of prolapse of allografts into the lumen of the respiratory tract, the laryngotracheostomy defect is sutured and the laryngotracheostomy is closed.

EFFECT: increasing the efficiency of treatment, reduction of the stages of reconstructive operations in the treatment of patients with extended laryngeal-tracheal obliteration, reduction of the probability of postoperative complications, preventing restenosis of the laryngeal-tracheal complex, elimination of the need for repeated surgical interventions, reduction of the duration of inpatient treatment and terms of rehabilitation of patients.
