To compare functional hearing preservation (HP) with a slim perimodiolar array (SPA) and a slim lateral wall array (SLW) in cochlear implantation (CI).
Retrospective chart review.
Tertiary referral center.
All adult, post-lingual CI recipients with serviceable preoperative hearing serially implanted with SPA or SLW electrodes from July 2015 through July 2018.
Cochlear implantation.
Hearing preservation (HP). Patients with a low frequency pure-tone average (LFPTA) (125, 250, 500 Hz) threshold less than 80 dB were considered HP candidates based on preoperative audiograms. Postoperative audiograms were obtained before activation. Successful HP was defined as retention of LFPTA less than 80 dB. The change in LFPTA (ΔLFPTA) was also calculated.
One hundred twenty one patients were implanted with either the SPA or SLW electrodes, 82 (42,40) of whom were HP candidates with postoperative audiograms. Average (standard deviation, SD) preoperative LFPTA was 54.86 [19.38] and 54.38 [13.58] dB for SLW and SPA respectively, with a mean ΔLFPTA of 24.6 [15.94] and 24.92 [16.66] dB. Successful HP was achieved in 21 (50%) and 22 (55%). Preoperative LFTPA, ΔLFPTA, and postoperative LFPTA were not significantly different (p = 0.89, 0.75, 0.93) between electrodes.
The SPA is as effective at immediate functional HP after CI as a SLW.
比较 Slim 经圆窗骨锚定式助听系统（SPA）和 Slim 侧骨壁式助听系统（SLW）在人工耳蜗植入（CI）中的功能听力保护（HP）效果。
回顾性图表分析。
三级转诊中心。
所有成人、后天性、植入 Slim 经圆窗骨锚定式助听系统或 Slim 侧骨壁式助听系统电极的、术前有可利用听力的、连续接受 CI 的患者。
人工耳蜗植入。
听力保护（HP）。基于术前听力图，将低频纯音平均阈值（125、250、500 Hz）（LFPTA）<80 dB 的患者视为 HP 候选者。在激活前获得术后听力图。成功的 HP 定义为 LFPTA 保留值<80 dB。还计算了 LFPTA 的变化（ΔLFPTA）。
121 名患者植入了 Slim 经圆窗骨锚定式助听系统或 Slim 侧骨壁式助听系统电极，其中 82 名（42、40）患者有术后听力图，符合 HP 候选者标准。SLW 和 SPA 的平均（标准差，SD）术前 LFPTA 分别为 54.86 [19.38] 和 54.38 [13.58] dB，平均 ΔLFPTA 分别为 24.6 [15.94] 和 24.92 [16.66] dB。成功的 HP 分别为 21 名（50%）和 22 名（55%）。电极之间术前 LFTPA、ΔLFPTA 和术后 LFPTA 无显著差异（p = 0.89、0.75、0.93）。
Slim 经圆窗骨锚定式助听系统在人工耳蜗植入后的即时功能 HP 方面与 Slim 侧骨壁式助听系统同样有效。
