Results after resection of intraoral cancer and reconstruction with the free radial forearm flap.

Between 1989 and 1996, 47 patients with an intraoral squamous cell carcinoma underwent tumor resection and reconstruction with a free volar forearm flap. Tumor resection and neck dissection were performed by a head and neck surgeon and the free tissue transfer by a plastic surgeon. Preoperative radiation therapy was given to 44 of 47 patients and postoperative radiation therapy to 2. One other patient was not irradiated. There were 15 females and 32 males, with a mean age of 61 years. The primary site of the cancer was the tongue in 15 cases, the floor of the mouth in 15, the tonsil in 10, the bucca in 3 and the retromolar trigone in 4 cases. The flap was harvested from the left forearm in 34 and from the right in 13 patients. The mean operation time was 10 h (range 6-20) and the mean intraoperative bleeding was 486 ml (250-2,500). Forty-four of 46 flaps healed completely. Twelve revisions on 9 free flaps were performed between 6 h and 6 days postoperatively. Overall revisional surgery was done in 9 of 47 cases (19%). Two flaps could not be saved (4%). Infections/fistulas in the neck occurred in 11 of 46 cases (24%). Complete healing of the donor site occurred at a mean of 2.5 months (1-5). Nine patients developed complications at the donor site, 3 hematomas and 6 superficial infections (19%). Twenty-seven of 47 patients are still alive (57%). The mean survival time was 49 months (16-71).
