| Abstract |
Purpose
：Anterolateral thigh and radial forearm flap is the most important fasciocutaneous flap widely used for reconstruction of tongue. One important purpose of flap is replacing the volume of tongue but still there is no data about the surface area and volume to be reconstructed after glossectomy. In this paper, surface area and volume is estimated from the 3-dimensionally reconstructed MRI images to see which flap is more ideal and to give the reference value for reconstruction. Materials and Methods：With coronal MRI image, tongue including only the intrinsic muscle is delineated in every section and reconstructed 3-dimensionally and calculated the volume and surface area to be reconstructed according to the degree of glossectomy. This volume and surface area was compared with the volume of anterolateral thigh and radial forearm flap. Results：The volume and surface area to be reconstructed in hemiglossectomy was 39.0±4.0cm 3 and 31.8±2.7cm 2 respec-tively. The average thickness of anterolateral thigh flap is 9.4±2.8mm and that of radial forearm is 3.8±1.0mm. Comparing the curve of tongue surface area and volume with the volume of flap, the anterolateral thigh flap has more ideal volume to replace the defect. Conclusions：The surface area and volume requested for reconstruc-tion could be suggested and the anterolateral thigh flap has more ideal volume for reconstruction of glossectomy defect. |
