[Simultaneous repairing defects of orbital floor and palate with the modified temporalis muscle flap after the maxillectomy].

To evaluate the outcome of one-stage reconstruction of maxillary and orbital defects with modified temporalis muscle flap (TMF) following the removal of malignant neoplasms. In this retrospective study, 15 patients underwent the reconstruction of defects of orbital floor and palate after maxillectomy for malignant tumor were included from June 2008 to June 2014. The modified temporalis muscle flap was used to repair the defects after surgery, and functional outcomes were analyzed. All the patients were followed up for 12-81 months. Three cases of them received preoperative radiotherapy and 12 cases underwent postoperative radiotherapy. All flaps were survived. Epithelization of the tissues in oral and nasal cavity was completed in 4-6 weeks. Good functional reconstruction on swallowing and speaking functional results were achieved with maxillary and orbital reconstruction and no secondary deformity of external nose was observed. The eye positions in all cases were normal. Diplopia, diminution and loss of vision were not found. The modified TMF can be used for simultaneous reconstruction for the defects of orbital floor and palate after maxillectomy in patients whom free tissue flap can not be applied to, showing better cosmetic and functional results.
