The following findings have been obtained as a result of investigating the patients with TM disorder before and after correction of the mandibular repositioning as it was considered that, if the sound transmitting middle ear hearing system which undergoes change along with the morbidity in progress shows reversible changing aspect in response to the ebb and flow of the morbidity, it would serve as quantitative diagnostic criteria regarding the repositioning by means of bite-plane therapy. Changes were observed between before and after repositioning in 3 item measurement. The values of static compliance, impedance and pressure of middle ear were reduced to the level of those in healthy subjects. Consequently, the following conclusions were reached: Impedance audiometry serves as quantitative judging criteria regarding the repositioning of the mandible by means of bite-plane therapy.
对颞下颌关节紊乱症患者在进行下颌重新定位矫正前后进行了调查，得到以下结果。由于随着病情进展而发生变化的传音性中耳听觉系统，若能对病情的消长呈现可逆的变化态势，那么这将可作为通过咬合平面疗法进行重新定位的定量诊断标准。在重新定位前后的3项测量中观察到了变化。中耳的静态顺应性、声阻抗和压力值降低到了健康受试者的水平。因此，得出以下结论：声阻抗测听法可作为通过咬合平面疗法进行下颌重新定位的定量判断标准。
