Abstract
Background
Tinnitus is a frequent symptom in cochlear implant (CI) patients. Many studies have shown that a CI leads to a significant change in the perception of tinnitus.
Aims
The aim of the present study was to evaluate the effect of CI on tinnitus in patients with Unilateral Cochlear Implant (UCI), Bilateral Cochlear Implant (BCI), and Bimodal Stimulation (BMS).
Material and Methods
A survey was administered online to CI patients. The Tinnitus Handicap Inventory (THI) score was calculated. Emotional, functional, and catastrophic subscales scores were calculated. The intensity and annoyance of tinnitus were graded using a scale from 1 to 10.
Results
130 participants represented the study group; the Average THI score was 38.3 (SD: 26.3) in UCI, 32.4 (SD 25.8) in BCI users, and 42.5 (SD 28.2) in BMS: no significant difference was found among the three groups. CI users for less than 1 year showed significantly higher THI scores compared to CI users for more than 5 years (p = .0275). The intensity and annoyance of tinnitus significantly decreased with the CI on compared to the CI off condition.
Conclusions and Significance
Taken together, our findings support CI’s efficacy in reducing the perception of tinnitus. No significant differences were evident between unilateral and bilateral electrical stimulation in terms of tinnitus improvement.
Chinese Abstract
背景：耳鸣是人工耳蜗植入 (CI) 患者的常见症状。 许多研究已经显示 CI 导致耳鸣感知的显著变化。
目的：本研究的目的是评估 CI 对植入单侧人工耳蜗 (UCI)、双侧人工耳蜗 (BCI) 和双峰刺激 (BMS) 的耳鸣患者的影响。
材料和方法：对 CI 患者进行了在线调查。 计算了耳鸣障碍清单 (THI) 评分。 还计算了情绪、功能和灾难性分量表得分。 对耳鸣的强度和烦人度进行1到10级的分级。
结果：130 名参与者代表研究组； 对于 UCI 植入者, 平均 THI 评分为 38.3（标准差：26.3）, BCI 植入者, 平均 THI为 32.4 (SD 25.8), BMS 植入者, 平均 THI为 42.5 (SD 28.2)：三组之中未发现显著差异。与使用 CI 超过 5 年的患者相比, 使用不到 1 年的患者表现出显著更高的 THI 评分 (p=.0275)。与 CI 关闭状态相比, CI 开启时耳鸣的强度和烦人度显著降低。
结论和意义：综上所述, 我们的研究结果支持 CI 有效地减少耳鸣的感知。在耳鸣改善方面, 单侧和双侧电刺激之间无明显差异。
