REINNERVATION OF FACIAL MUSCLES METHOD Russian patent published in 2020 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: present invention refers to medicine, namely to maxillofacial, reconstructive, plastic surgery, and can be used to form isolated movements of the middle and lower face zones in the patients with facial muscle paralysis. Disclosed is a method for reinnervation of facial muscles is performed by dissecting skin and subcutaneous fat on the injured and healthy sides with pre-bovine access, further along the hair growth line, delamination of the skin-fat flap to the front edge of the parotid gland with subsequent separation of the musculo-aponeurotic layer, separation and mobilization of the parotide posterior border from the cartilaginous part of the external tragola, the anti-tracheal and intercostal incision, then, on the involved side, the facial nerve is isolated and cut off within the exit of the ligamentous opening and the parenchyma of the parotid gland is excised. Trunk and branches of the facial nerve are isolated in the parotid gland and the facial nerve is divided into an upper part with temporal, bilge and cheek branches and a lower part with marginal and cervical branches. Hypoglossal nerve is separated in the region of the anterior portion of the two-abdominal muscle, and 30–40 % of its fascicles are incised with subsequent collection of the autograft autograft. It is conducted from the affected side to the healthy one under the previously isolated skin-fat flap through an oral cavity under the mucous membrane and sutured together with a buccal branch of the facial nerve with layer-by-layer suturing of the soft tissues.

EFFECT: invention provides higher functional and aesthetic results in patients with damage of mastication branch of trigeminal nerve.
