To determine the two-dimensional (2D) characteristics of flaps necessary to create three-dimensional (3D) tongue anatomy.
Dissection of 11 fresh, nonpreserved human cadavers was performed. Six defects in each were created: total tongue, total oral tongue, hemiglossectomy, oral hemiglossectomy, total base of tongue, and hemi-base of tongue. The resections were debulked to create flat, 2D mucosal flaps. The dimensions and shapes of these flaps were determined.
Each specimen showed consistent dimensions and geometry between cadavers. The total tongue was pear-shaped, the total oral tongue was egg-shaped, the oral hemi-tongue was bullet-shaped, the hemi-tongue resembled a dagger, the total base of tongue was rectangular, and the hemi-base of tongue was hour-glass shaped.
Typical dimensions and shapes of common tongue defects were determined. It is conceivable that customizing reconstructive flaps based on these data will increase the accuracy of neo-tongue reconstruction, and thus, improve functional outcomes.
确定创建三维（3D）舌解剖结构所需的二维（2D）皮瓣特征。
对 11 具未经保存的新鲜人体尸体进行解剖。每个尸体创建 6 个缺陷：全舌、全口腔舌、半舌切除术、口腔半舌切除术、全舌根和半舌根。切除物被去块以形成平坦的 2D 黏膜皮瓣。确定这些皮瓣的尺寸和形状。
每个标本在尸体之间显示出一致的尺寸和几何形状。全舌呈梨形，全口腔舌呈卵形，口腔半舌呈子弹形，半舌呈匕首形，全舌根呈矩形，半舌根呈沙漏形。
确定了常见舌缺损的典型尺寸和形状。可以想象，根据这些数据定制重建皮瓣将提高新舌重建的准确性，从而改善功能结果。
