METHOD OF PLASTICS OF SURGICAL DEFECT AFTER SUBTOTAL BLOCK RESECTION OF THE TEMPORARY BONE PYRAMID Russian patent published in 2019 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, neurosurgery, can be used in the surgical treatment of patients with tumors of the skull base, mainly its lateral section with an invasive growth pattern and significant intracranial spread. After the periosteal-occipital flap is collected and translocated on a pedicle, a skin incision is made in the ear region, approaching the neck to its middle third and the scalp to the coronary suture. Aponeurosis is cut vertically in the projection of the posterior margin of the temporal line and, by separating from the skin and aponeurosis in the occipital region, a musculoskeletal flap is formed on the basis of the temporal muscle, with attachment to the skull bone in the temporal region. Trepanning of the skull is carried out in the temporal region with preservation of the site of attachment of the temporal muscle, musculoskeletal flap on the temporal muscle is removed anteriorly. Subtotal block resection of the temporal bone pyramid is carried out. After the main stage of tumor removal is completed, a rotated periosteal-occipital flap is placed in the bed, over which the musculoskeletal flap is rotated and fixed with its system for attaching the bone.

EFFECT: method provides adequate closure of the surgical wound, reducing the risk of postoperative local complications, acceptable cosmetic result, reducing the duration of the operation and the amount of intraoperative blood loss.
