| 成果简介 | NOVELTY - Invention refers to medicine, namely to maxillofacial surgery, reconstructive and plastic surgery, oncology. At the first stage, MRI and CT images of patients with tongue cancer with contrast enhancement are analysed, the volume and configuration of the removed portion and the size of the formed defect are determined. At the second stage, MSCT of the upper limb with contrast enhancement is performed to determine the diameter of the main great vessels of the arm and to detect the anatomical features of the vessels. That is followed by contrast-enhanced maxillofacial MSCT to determine vascular current of the external carotid artery and select suitable vessels for the future microsurgical anastomosis. At the third stage, a tongue resection template is formed and transformed into a surface. At the fourth stage, the area of said surface is increased by 15 %. Based on the size and shape of this surface, a template is made for resection of a donor radial flap with a neurovascular bundle from the forearm, which is applied on the forearm taking into account the location of the vessels according to the MSCT data. At the fifth stage, a surgical intervention is performed, during which a tongue with a tumour is resected according to pre-designed templates. Further, a radial flap with a neurovascular bundle is formed. After that, the formed flap is placed in the area of the formed defect, covering its entire surface. Tunnel is formed in 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 this tunnel the vessels of the vascular pedicle are laid. Above vessels are sutured end-to-end, a lateral forearm cutaneous nerve end-to-end with a lingual nerve. Then the transplant is fixed. Wounds on neck and forearm are closed layer-by-layer with interrupted sutures. USE - Medicine. ADVANTAGE - Method enables eliminating the tongue defect immediately after the hemiglossectomy in the patients with malignant new growths of the tongue, taking into account the further change in the volume of the tongue after chemoradiation therapy, restore the swallowing function and improve the results of speech, reduce the number of complications, reduce the length of the anaesthetic aid. 1 cl, 17 dwg, 1 ex |
