METHOD FOR LARYNX AND TRACHEA PLASTY Russian patent published in 2014 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: skin surrounding a laryngostoma is mobilised under an endotracheal anaesthesia with nasal intubation. The skin is vertically incised in a projection of a sternum. Anterolateral presternums are mobilised A periosteal-spongy pedicle flap of sternal portions of nodding muscles from both sides with using an electric pen and a flat chisel. The flap is modelled, rotated upwards, laid with the periosteum down into a lumen of a prospective larynx. That is followed by skin incision in a projection of the thoracoacromial artery on the right. A greater pectoral muscle is mobilised and used to cut out an axial pedicle flap containing the thoracoacromial artery with a musculofascial plate fitting the size of the wound defect on the neck. The flap is rotated on the neck in the subcutaneous tunnel and anchored to the ends of soft tissue and skin defects. The flap surface on the neck from outside is covered by a split skin graft from an anterior surface of the hip.

EFFECT: method provides the one-stage restoration of larynx lumen and soft tissue defect of the anterior neck by using the periosteum and a spongy layer of the presternum and mesosternum, and the pedicle flap of the greater pectoral muscle.
