Abstract:
Objective To evaluate the effect of double-leaf perforator free flap pedicled with posterolateral calf peroneal artery on repairing facial through-and-through defect after oral cancer oblation.Methods Nine patients with facial through-and-through defects after oblation of oral and maxillofacial malignancies,including 4 cases of buccal mucosa carcinoma,2 cases of maxilla osteosarcoma,1 case of carcinoma of the maxillary sinus and 2 cases of parotid duct carcinoma,were recruited from May,2016 to May,2018.The flap was used to repair the facial defect of recruited patients.The area of the bigger leaf of bilobed perforator flap was 7.0 cm×8.0 cm-6.0 cm×7.0 cm and the small leaf was 4.5 cm×4.5 cm-4.0 cm×4.0 cm,respectively.The intraoral and facial defects needed to be reconstructed contained the oral mucosal of the upper palate,the skin,subcutaneous tissue and mucosa of the cheek.The radiotherapy was performed 1.0-1.5 months after the operation.The prognosis including appearance,mouth opening,and the functions of deglutition,and language were assessed.Results Through 3-18 months outpatient followed-up,all 9 cases of transplanted flaps survived well and the incisions of the donor and recipient areas healed by first intention.The patients were satisfied with the facial appearance,mouth opening,and the functions of deglutition and language at the 6 months follow-up.The radiotherapy had no damage on the survival of the bilobed perforator flap.There was no recurrence or metastasis in follow-up.Conclusion The double-leaf perforator free flap pedicled with posterolateral calf peroneal artery is an ideal free tissue for repairing the facial perforating defect after oral cancer oblation because of its constant blood vessel,abundant tissues,flexible design and operating methods.
