摘要
人工耳蜗植入(CI)后电极阵列产生电刺激时,耳蜗内电流电压分布情况可通过电极记录并体现为阻抗或跨阻(impedance/transimpedance).跨阻矩阵(transimpedance matrix,TIM)测量是利用人工耳蜗遥测功能的一种客观测量工具,具有操作简便、数据处理快捷、结果准确的特点,近年来在人工耳蜗植入术中应用已有报道,并在术中电极位置的评估、术后心理物理响度及神经兴奋扩散的测量等方面展示出相应的应用潜力.本文将介绍跨阻矩阵测量的原理与方法,并回顾跨阻矩阵测量在人工耳蜗植入领域应用的主要研究进展.
Abstract
When electrical stimulation is generated by the electrode arrays of cochlear implant(CI),the cur-rent-voltage distribution in the cochlea can be recorded by the electrodes and reflected as impedance or transimped-ance.Transimpedance matrix(TIM)measurement is an objective measurement tool that utilizes the telemetry func-tion of the cochlear implant,which has shown clinical applicability in recent years for cochlear implantation.TIM of-fers convenient operation,speedy data processing,and accurate results,and has demonstrated potential application in the evaluation of electrode position intraoperatively,measurement of postoperative psychophysical loudness and assessment of neural excitation diffusion.We will introduce the principles and methods of TIM measurement and re-view the main research progress in the application of TIM measurement in cochlear implantation.
