摘要

目的

探讨人工耳蜗植入术中蜗内耳蜗电图（electrocochleography， ECochG）实时监测技术的标准化操作流程。

方法

在常规人工耳蜗植入手术中，建立术中蜗内ECochG实时监测标准化流程，包括设备连接与校准、声刺激参数设置等，通过主刀医生与听力师协同操作，实时反馈术中动态监测结果，指导调整电极植入角度与速度，电极植入后行多通道ECochG评估。

结果

术中ECochG监测可实时反映基底膜毛细胞功能状态，是保护残余听力、提高人工耳蜗植入精准性的关键手段。

结论

术中蜗内ECochG监测技术建立标准化操作流程可减少误差风险，为临床广泛推广提供参考。

Abstract

Objective

To establish a standardized protocol for real-time intracochlear ECochG monitoring during cochlear implantation surgery.

Methods

During routine MED-EL cochlear implantation surgeries

a standardized real-time intracochlear ECochG monitoring protocol was established

including equipment connection and calibration

acoustic stimulation parameter settings

etc. Through collaborative operation between the surgeon and audiologist

real-time ECochG feedback guided intraoperative adjustments of electrode insertion trajectory and insertion rate. Post-electrode insertion and multi-channel ECochG evaluation were performed.

Results

Intraoperative ECochG monitoring can reflect the functional status of the basilar membrane hair cells in real time

serving as a critical measure for preserving residual hearing and improving the precision of cochlear implantation.

Conclusion

Establishing a standardized operational procedure for intracochlear ECochG monitoring can reduce the risk of errors and provide a reference for broader clinical adoption.
