The lateral tongue flap which was first described in 1956 by Klopp and Schurter is a pedicle flap from the lateral border of the tongue to the defect after resection of malignant tumors. The excellent blood supply to the tongue means that few complications occur, therefore this flap is probably indicated in irradiated cases. In this paper, three cases using the lateral tongue flap following resection of malignant tumor which have been preoperatively irradiated are reported. Case 1: Squamous cell carcinoma of the left buccal mucosa. 45 Gy radiation was given preoperatively and 25.2 Gy postoperatively. Case 2: Squamous cell carcinoma of the right buccal mucosa and gingiva. 73.8 Gy radiation was given preoperatively. Case 3: Squamous cell carcinoma of the left retromolar trigone. 67.8 Gy radiation was given preoperatively. In every case, partial separation of the suture and necrosis of the distal part of the flap were observed in 5-10 days after the operation. Case 1, the separation and necrosis healed in 4 months after the operation. Case 2, these healed in 2.5 months after the operation. Case 3, although the partial separation of the suture partly remained, the necrotic tissue was replaced with granulation tissue and epithelized. The remnant tongues in our cases had no complications in swallowing and articuration.
