摘要

目的：三相脉冲模式（TPP）是控制人工耳蜗植入后面神经刺激（FNS）的成功策略之一。本研究评估从双相脉冲模式（BPP）转移到TPP患者的电极阻抗（EI）变化。材料和方法本回顾性研究是对经历过FNS的ci后患者进行的，并采用TPP策略进行管理。将TPP与BPP的拟合参数进行比较，包括电极阻抗、最大舒适水平（MCL）、阈值水平（THR）和相持续时间。结果本研究纳入25只植入耳。与BPP相比，在头两个尖触点切换到TPP时，电极触点的阻抗显著降低（第一次触点为7.0±2.7 vs. 7.8±3.4 kΩ，第二次触点为6.5±2.4 vs. 7.1±2.9 kΩ）。与BPP相比，在前10个电极接触时，TPP的MCL在统计学上有显著增加。结论TPP刺激是治疗FNS的有效策略。在FNS患者中，使用TPP时，大多数根尖阻抗值降低，MCL升高。这些发现表明，TPP可能被认为是FNS患者的常规和成功的模式。未来的研究应该调查不同刺激模式对CI结果的影响。证据水平

Cochlear Implantation: Electrode Impedance in Users With Triphasic Pulse Pattern

Objectives

The triphasic pulse pattern (TPP) is one of the successful strategies for managing facial nerve stimulation (FNS) after cochlear implantation (CI). This study evaluates the electrode impedance (EI) changes for patients who were shifted from the biphasic pulse pattern (BPP) to TPP.

Materials and Methods

This retrospective study was conducted on the patients who experienced FNS post-CI and were managed with a TPP strategy. The fitting parameters with TPP were compared to those with BPP, including electrode impedance, maximum comfortable levels (MCL), threshold levels (THR), and phase duration. .

Results

This study included 25 implanted ears. The impedances of the electrode contacts significantly decreased when shifted to TPP at the first two apical contacts compared to the BPP (7.0 ± 2.7 vs. 7.8 ± 3.4 kΩ at the first contact and 6.5 ± 2.4 vs. 7.1 ± 2.9 kΩ at the second contact, respectively). The MCL showed a statistically significant increase with TPP compared to the BPP at the first 10 electrode contacts.

Conclusion

The TPP of stimulation appears to be a successful strategy for managing FNS. Among the patients with FNS, there is a decrease in the most apical impedance values and an increase in MCL when using TPP. These findings suggest that TPP might be considered a routine and successful pattern for FNS patients. Future studies should investigate the impact of different stimulation patterns on CI outcomes.
