摘要
在安装人工耳蜗(CI)时,通过测量电诱发的镫骨反射,可以可靠地估计最大舒适度,从而使人工耳蜗的编程具有较高的听力舒适度和良好的言语理解能力。在手术过程中,通过手术显微镜观察术中镫骨反射,并确定每个植入通道所需的刺激水平。术中镫骨反射检测既是听神经对直至脑干的电刺激做出反应的指标,也是对术后镫骨反射测量能力的测试。术后镫骨反射阈值可用于估计 CI 装配过程中的上限刺激水平。特别是对于无法提供响度感知反馈的儿童或患者,这种方法可以避免 CI 刺激不足,从而导致听力表现不佳。此外,还可以避免过度刺激,因为过度刺激甚至会导致患者拒绝使用设备。
Electrically Evoked Stapedius Reflex Measurements in Cochlear Implantation and its Application in the Postoperative Fitting Process.
Measuring the electrically evoked stapedius reflex during the fitting of cochlear implants (CIs) provides a reliable estimation of maximum comfort levels, resulting in the programming of the CI with high hearing comfort and good speech understanding. Detection of the stapedius reflex and the required stimulation level on each implant channel is already being performed during surgery, whereby intraoperative stapedius reflexes are observed through the surgical microscope. Intraoperative stapedius reflex detection is both an indicator that the auditory nerve is responding to electrical stimulation up to the brainstem and a test for the ability to perform postoperative stapedius reflex measurements. Postoperative stapedius reflex thresholds can be used to estimate upper stimulation levels in the CI fitting process. In particular, in children or patients unable to provide feedback on loudness perception, this method avoids inadequate stimulation with the CI, which can result in poor hearing performance. In addition, overstimulation can be avoided, which could even lead to refusal to use the device.
期刊介绍:
JoVE, the Journal of Visualized Experiments, is the world''s first peer reviewed scientific video journal. Established in 2006, JoVE is devoted to publishing scientific research in a visual format to help researchers overcome two of the biggest challenges facing the scientific research community today; poor reproducibility and the time and labor intensive nature of learning new experimental techniques.
