摘要
目的:评估经验丰富的单侧耳聋(SSD CI)人工耳蜗用户的客观和主观听力结果,这些用户使用的是通过基于解剖的适配(ABF)和基于临床的适配(CBF)创建的适配图:12 名患有舌后听力损失的 SSD CI 用户:使用术后高分辨率平板容积计算机断层扫描确定耳蜗内电极接触位置。根据这些位置,得出每个通道的相应中心频率和带宽。这些都被应用到临床拟合软件 MAESTRO 中,以生成针对每个用户的个性化 ABF 地图:对 ABF 和 CBF 地图进行比较。主要结果测量:比较 ABF 图和 CBF 图,评估安静和噪声中的客观语音感知、双耳效应和自我感觉音质:与 CBF 地图相比,ABF 地图的噪声语音感知得分明显更高(平均 SRT50:S0NCI 配置为-6.49 vs. -4.8 dB SNR,S0N0 配置为-3.85 vs. -2.75 dB SNR)。使用 ABF 地图后,求和效应和静噪效应明显增加(求和信噪比为 0.86 对 0.21 分贝,静噪信噪比为 0.85 对 -0.09 分贝)。使用 ABF 地图后,安静环境中的语音感知和空间掩蔽释放均未得到改善。据报告,每种地图的自我感觉音质水平相似。研究结束时,所有用户都选择保留 ABF 地图。这种偏好与电极阵列的角度插入深度无关:结论:有经验的 SSD CI 用户更喜欢使用 ABF 地图,它能显著改善他们的双耳听力和某些方面的言语感知。
Anatomy-based fitting improves speech perception in noise for cochlear implant recipients with single-sided deafness.
Objective: To evaluate objective and subjective hearing outcomes in experienced cochlear implant users with single sided deafness (SSD CI) who used fitting maps created via anatomy-based fitting (ABF) and clinically-based fitting (CBF).
Participants: Twelve SSD CI users with postlingual hearing loss.
Intervention: OTOPLAN (Version 3. (MED-EL) was used to determine intracochlear electrode contact positions using post-operative high-resolution flat panel volume computed tomography. From these positions, the corresponding center frequencies and bandwidths were derived for each channel. These were implemented in the clinical fitting software MAESTRO to yield an ABF map individualized to each user.
Main outcome measures: ABF and CBF maps were compared. Objective speech perception in quiet and in noise, binaural effects, and self-perceived sound quality were evaluated.
Results: Significantly higher speech perception in noise scores were observed with the ABF map compared to the CBF map (mean SRT50: -6.49 vs. -4.8 dB SNR for the S0NCI configuration and - 3.85 vs. -2.75 dB SNR for the S0N0 configuration). Summation and squelch effects were significantly increased with the ABF map (0.86 vs. 0.21 dB SNR for summation and 0.85 vs. -0.09 dB SNR for squelch). No improvement in speech perception in quiet or spatial release from masking were observed with the ABF map. A similar level of self-perceived sound quality was reported for each map. Upon the end of the study, all users opted to keep the ABF map. This preference was independent of the angular insertion depth of the electrode array.
Conclusions: Experienced SSD CI users preferred using the ABF map, which gave them significant improvements in binaural hearing and some aspects of speech perception.
