Cochlear implants allow measures of neural function, through Neural response telemetry (NRT) and Auditory nerve recovery function (REC). These help in programming the speech processor and understanding the auditory system. However, not many studies have evaluated and compared these in different regions of the cochlea.
Comparing NRT and REC in different regions of the cochlea.
Cross-sectional, descriptive and prospective. NRT and REC (through the function of T0 - absolute refractory period, A - amplitude and TAU - time constant of the relative refractory period parameters) were evaluated, in three groups according to the stimulated electrode of the cochlea: apical, medial and basal.
26 adult patients were evaluated, 2 bilateral, totalling 28 ears. Data analysis showed no statistically significant difference between NRT between medial and basal but showed between apical and medial and apical and basal. For T0, there was a significant difference between medial and basal; for A, there was a significant difference between apical and basal and also medial and basal; and for TAU, there was no significant difference.
There was a statistically significant difference in NRT and REC when compared between different regions of the cochlea.
人工耳蜗允许通过神经反应遥测（NRT）和听神经恢复功能（REC）来测量神经功能。这些功能有助于对言语处理器进行编程和了解听觉系统。然而，并没有很多研究评估和比较耳蜗不同区域的这些功能。
比较耳蜗不同区域的 NRT 和 REC。
这是一项横断面、描述性和前瞻性研究。根据耳蜗刺激电极，将 NRT 和 REC（通过 T0-绝对不应期、A-振幅和 TAU-相对不应期参数的时间常数参数）评估为三组：顶端、中间和基底。
共评估了 26 例成年患者，其中 2 例为双侧，共计 28 只耳朵。数据分析显示，中间和基底的 NRT 之间没有统计学上的显著差异，但顶端和中间以及顶端和基底之间有显著差异。对于 T0，中间和基底之间有显著差异；对于 A，顶端和基底以及中间和基底之间有显著差异；对于 TAU，没有显著差异。
当比较耳蜗不同区域时，NRT 和 REC 存在统计学上的显著差异。
