METHOD FOR RECOVERING RESPIRATORY FUNCTION OF LARYNX AND TRACHEA FOLLOWING FORMATION OF LARYNGOTRACHEOSTOMA AND TRACHEOSTOMA Russian patent published in 2015 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: fasciocutaneous flaps are cut out around a laryngostoma or a tracheostoma having a lateral width of 1.0cm, and a top and bottom width of 0.5cm. The flaps are partially mobilised to form side walls and to enlarge a lumen of the larynx and trachea. They are anchored to neck muscles. An anterior wall of the larynx and trachea is created and closed by cutting out a tongue-shaped skin graft. The flap is separated, mobilised upwards with arterial vessels preserved. The formed flap is turned around approximately 60°. The flap is fixed by interrupted sutures along the perimeter with the formed walls of the laryngo- and tracheostoma. The skin sutures are applied along the perimeter of the wound defect.

EFFECT: recovering the respiratory and vocal function, preventing the stenosis progression by forming a stable lumen of the larynx and trachea, as well as performing the one-staged operation, providing the good functional and aesthetic effect by using two fasciocutaneous flaps of the patients as a plastic material.
