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.
