Abstract: Objective:  To evaluate the clinical outcome of pectoralis major myocutaneous flap.in oral and maxillofacial reconstruction after ablative surgery of malignant tumor. Methods: The clinical date of 91 cases underwent  pectoralis major myocutaneous flap procedures for the immediate reconstruction of defects after resection of oral or maxillofacial malignant tumors from 2010 to 2016 were analyzed retrospectively. Results:  The pectoralis major myocutaneous flap in  81 cases survived completely, 6 cases survived mostly(≥70%), and the clinical effect were satisfactory（95.60%）. Conclusion: The pectoralis major myocutaneous flap is relatively idea for reconstruction of defects after ablative surgery in oral and maxillofacial malignancies.
