[Clinical application of mandibular osteomuscular flap pedicled with temporalis to repair maxillary bone defect].

Objective: To evaluate the clinical effect of mandibular osteomuscular flap pedicled with temporalis to repair maxillary defect.
Methods: From March 2008 to May 2010, ten cases of maxillary defects resulted from malignant tumor resection were treated with mandibular osteomuscular flap pedicled with temporalis. Ten cases of malignant tumor included six cases of Squamous cell carcinoma,one case of duct carcinoma, osteosarcoma, chondrosarcoma and malignant melanoma. One case was repaired by mandibular osteomuscular flap only, nine cases were repaired by mandibular osteomuscular flaps combined with other soft tissue flaps.
Results: All the 10 mandibular osteomuscular flaps survived completely with no complication. The patients were followed up for 12 to 36 months, with an average of 18 months. Satisfactory appearance and complete functional restoration were achieved except for one case of chondrosarcoma recurrence.
Conclusions: The mandibular osteomuscular flap pedicled with temporalis is safe and easily performed with less complication. It is an ideal method for repairing the maxillary defect.
