Vascular iliac myofascial flap to repair compound defect of the jaw.

The vascular iliac myofascial flap is a compound flap with the deep circumflex iliac artery (DCIA) as the vascular pedicle, carrying the iliac bone and parts of the internal oblique, external oblique and muscle-fascial tissue that cover the surface of the iliac crest and inside the iliac bone. The aim of this study was to advocate a feasible surgical strategy for maxillofacial surgeons through our review of clinical applications and to improve the quality of life of patients after the operation. In recent years, Stomatology Hospital of Wuhan University has performed dozens of vascularized iliac myofascial flaps, not only to repair jaw defects but also to complete the repair of intraoral soft tissue defects. 20 patients were followed up. These patients with jaw tumors who received a vascular iliac myofascial flap to repair compound defects of the jaw from 2018 to 2020. The Quality of Life Questionnaire-Head and Neck Cancer-37 (QLQ-H&N37) was used to evaluate their speech function (Z=-0.061, P>0.05) and postoperative aesthetics (Z=-2.824, P<0.05). All patients obtained good surgical results and satisfaction in terms of aesthetics and function. The successful reconstruction of these cases prove that the vascularized iliac composite flap with myofascial tissue is a reliable flap for the reconstruction of maxillofacial defects.
