用于人工耳蜗编程的术中电诱发镫骨肌反射阈值（eSRT）：一项术后验证研究。

文献信息

中文摘要

目的： 确定术中电诱发镫骨肌反射阈值（eSRT）是否与术后eSRT相关，并能否预测人工耳蜗患者的编程水平。
设计： 在三级医院进行的前瞻性队列研究。纳入77例接受人工耳蜗植入手术的患者。在电极E1、E6、E12、E17和E22处进行术中和术后eSRT测试，术后测试在中位4周时进行。
结果： 77例患者中的84个人工耳蜗符合纳入标准，其中72耳尝试了术中eSRT，50耳进行了术后测试。术中反应率总体显著高于术后反应率（83.1% vs. 70.9%，p = 0.0005），在中部和顶部电极处反应率最高。术中阈值中位数显著高于术后阈值（21.2 vs. 15.6，p < 0.0001），但两个时间点之间未观察到显著相关性。
结论： 术中eSRT可行，并产生了高反应率，尤其是在顶部和中部电极处。然而，术中阈值与早期术后值不相关，目前不能预测早期术后eSRT。这些发现支持术中eSRT作为定性术中工具的实用性，但需要进一步改进以提高其对术后人工耳蜗编程的预测价值。

英文摘要

OBJECTIVE: To determine if intraoperative electrically evoked stapedial reflex thresholds (eSRT) correlate with postoperative eSRT and can predict programming levels in cochlear implant patients.
DESIGN: Prospective cohort study conducted at a tertiary hospital. Seventy-seven patients who underwent cochlear implant surgery were included. Intraoperative and postoperative eSRT testing was performed at electrodes E1, E6, E12, E17, and E22, with postoperative testing conducted at a median of 4 weeks.
RESULTS: Eighty-four cochlear implants in 77 patients met inclusion criteria, with intraoperative eSRT attempted in 72 ears and postoperative testing in 50. Intraoperative response rates were significantly higher than postoperative rates overall (83.1% vs. 70.9%, p = 0.0005), with the highest rates at middle and apical electrodes. Median intraoperative thresholds were significantly higher than postoperative thresholds (21.2 vs. 15.6, p < 0.0001), but no significant correlations were observed between the two time points.
CONCLUSION: Intraoperative eSRT was feasible and yielded high response rates, particularly at apical and middle electrodes. However, intraoperative thresholds did not correlate with early postoperative values and cannot currently predict early postoperative eSRTs. These findings support the utility of intraoperative eSRT as a qualitative intraoperative tool, but further refinement is needed to improve its predictive value for postoperative cochlear implant programming.
