[Use of lower trapezius musculocutaneous pedicle flap in repairing of maxillofacial region penetrating defect].

OBJECTIVE: To investigate an safe and effective new technology (treatment) to repair maxillofacial region penetrating defect. METHODS: The lower trapezius musculocutaneous flap is parallel just like as two leaves which is connected to each other, and was folded to provide the liner of oral cavity and external cover. RESULTS: Totally twelve folding lower trapezius musculocutaneous pedicle flap survived. Postoperative follow-up for 1 approximately 3 years, the patients restored the function as well as the shape of maxillofacial region. CONCLUSIONS: The lower trapezius musculocutaneous pedicle flap is a suitable material for maxillofacial region reconstruction, further more, the successful rate is perfect.
