舌头具有复杂的肌肉结构，其运动功能也很复杂。因此，使用舌的计算生理模型来检查其在正常和病理条件下的重要功能将是有益的。迄今为止，舌模型的研究主要集中在正常语音的对称运动上。为了临床目的，有必要开发一个生理模型来处理日常的重要活动，如咀嚼和吞咽。为此，我们构建了一个完整的三维生理模型的基础上，从一个正常的主题的MRI数据的舌，并验证了基于解剖和生理知识的模型的基本功能。在这项研究中，该模型被应用到临床问题：预测和验证的变化，舌肿瘤的运动之前和之后，分别。舌前突和舌侧屈运动被用于预测和验证。模拟结果与舌部肿瘤患者的观察结果一致。仿真结果与临床观察结果的比较表明，该模型可以预测舌切除术对舌运动的潜在影响。这表明，该模型是一个有用的工具，术前规划舌切除术。
The tongue possesses a complex muscular structure, and its motor functions are also intricate. Therefore, it would he beneficial to use a computational physiological model of the tongue to examine its vital funotions in normal and pathological conditions. Thus far, the studies of tongue models have focused on symmetric movements for normal speech. For clinical purposes, it is necessary to develop a physiological model to deal with daily vital activities such as mastication and swallowing. To do so, we constructed a full 3D physiological model of the tongue based on MRI data from a normal subject, and verified the basic functions of the model based on anatomic and physiological knowledge. In this study, the model was applied to clinical issues: prediction and verification of the changes in movements of the tongue with a tumor before and after partial glossectomy, respectively. Tongue protrusion and lateral bending motion were examined for the, prediction and verification. The simulation results were consistent with the observations for a patient with a tumor in the tongue. Comparisons of the simulation and observation in the clinical case showed that, the model could predict potential effects of the glossectomy on the tongue movements. It is suggested that the model is a useful tool for pre-operative planning of glossectomy.
