METHOD FOR ELIMINATING RESTRICTION OF MOUTH OPENING IN CANCER PATIENTS AFTER COMBINED TREATMENT Russian patent published in 2023 - IPC A61B17/24 A61B6/03 A61B5/55 

FIELD: medicine.

SUBSTANCE: namely maxillofacial surgery, dentistry, reconstructive, plastic surgery and oncology. At the first stage, contrast-enhanced MRI and CT images taken before surgery to remove a tumor of the maxillofacial area are analyzed. The volume and configuration of the removed area and the size of the resulting defect are determined. At the second stage, a contrast-enhanced CT scan of the upper limb is performed to determine the diameter of the main great vessels of the arm and detect the anatomical features of the vessels. Then, MSCT of the maxillofacial area with contrast is performed to determine the vascular flow of the external carotid artery and suitable vessels for future microsurgical anastomosis are selected. At the third stage, surgical intervention is performed, during which all scar tissue formed in the oral cavity after combination therapy is removed. The radial flap is formed in such a way that its size and configuration corresponds to the size and configuration of the removed area, determined at the first stage according to preoperative CT images. A vascular pedicle is formed. After this, the formed flap is placed in the area of the formed defect, covering its entire surface. A tunnel is formed in the soft tissues from the origin of the vascular pedicle to the point of contact of the flap vessels with the donor vessels of the external carotid artery, into which the vessels of the vascular pedicle of the flap are then placed. The indicated vessels are sutured end-to-end. After this, the graft is fixed. Wounds on the neck and forearm are closed in layers with interrupted sutures. 7-10 days after the operation, the patient begins mechanotherapy, which lasts at least 10 weeks.

EFFECT: eliminating restrictions on mouth opening, restoring chewing function and improving the results of mechanotherapy and physiotherapy.
