Objective To evaluate the modified temporalis muscle flap (TMF) for correcting depressed deformity of donor site after surgery. Methods In this retrospective study, 15 patients with malignant maxillary tumor were involved. The modified temporalis muscle flap was used to repair the defect after tumor resection. Results All the patients were followed up for 12-54 months. All flaps were survived, except one case suffered from operative incision split and healed itself 3 months after radiotherapy. Epithelization of the fascia in oral cavity was completed in 4-6 weeks. Good functional reconstruction was achieved and no temporal deformity was observed. The cosmetic results were better compared with traditional temporalis muscle flap. Conclusion The modified TMF, the same as traditional temporalis muscle flap, can be served as the first-line reconstructive option for maxillary defects. And it can get better temporal cosmetic results with more satisfaction.
