Abstract: PURPOSE: To evaluate the value of deep inferior epigastric perforator flap in repairing postoperative defects after total tongue resection due to cancer. METHODS: From January 2018 to July 2018, deep inferior epigastric perforator flap was used to repair 13 total tongue defect after tongue carcinoma resection. All the deep inferior epigastric arteries were anastomosed with superior thyroid anteries or facial arteries, while the venae eomitans were anastomosed with the external jugular venae or the branches of internal jugular venae. RESULTS: Thirteen DIEP flaps survived uneventfully, the shape of the flaps in reconstruction of total tongue was satisfactory, the function was also satisfying. The donor area was closed directly. Of 13 patients, only one had abdominal wound infection, which was cured by dressing change. All abdominal wounds were healed leaving linear scar, the function of rectus abdominis was not affected obviously, and no complications such as abdominal wall hernia and abdominal wall protuberance were found. CONCLUSIONS: DIEP flap is rich in tissue, reliable in blood supply, good in shape and function. The complications of donor area are minimized. It is a new and reliable technique for reconstruction of total tongue defect.
