Abstract

Abstract: Objective: To investigate the clinical application of medial sural artery perforator flap in repairing postoperative defects of oropharyngeal malignant tumors. Methods: The main blood supply vessels and perforating branches were dissected by simulated operation on the sural muscle region of 5 specific cadavers, and the anatomical images were analyzed by Image-Pro Plus6.0 software. From September 2020 to September 2022, 8 cases of oropharyngeal malignant tumors were repaired with medial gastrocnemius artery perforator flaps. Results: The mean vascular pedicle length of the medial sural artery perforator flap was (10.82±0.89) cm, and the mean vascular diameter of the starting end of the medial sural artery was (3.13±0.31) mm. A total of 8 patients with oropharyngeal malignant tumors were repaired with medial sural artery perforator flaps. All flaps survived completely, and there were no obvious postoperative complications at the donor site. Conclusion: The medial sural artery perforator flap is a good choice for repairing the defect after oropharyngeal malignant tumor surgery with long pedicle, suitable diameter, and no obvious complications in donor site.
