Clinical application of free flap for head and neck reconstruction in 244 patients

Objective To analysis the results of different free flaps for reconstruction of head and neck defects.Methods From January,2010 to December,2013,243 free flaps were performed in 244 patients in this retrospective study.Evaluated parameters were defect localization,histology of tumor,free flap type,recipient vessels and complications.Results Total 243 free flaps were transplanted successfully except 6 flaps failured.The overall flap survival rate was approximately 97.6％.Thirty-three cases were encountered vascular complication,which rate was 5.2％.There were arterial crisis in 2 cases and venous crisis in 11 cases.Seven cases survived by explorative operation.The flap salvage rate was 54％.Seventy-three cases suffered local or systemic complications,and overall complication rate was 29.9％.The anterolateral thigh flap was most commonly used,followed by free fibula flap and free radial forearm flap.Conclusion Free flap is a reliable method for reconstruction of head and neck defect.
