Abstract

ObjectivesTo evaluate the effects of cochlear implantation on speech recognition in noise, sound localization, QoL, and tinnitus in adults with SSD.

Material and methods: This retrospective cohort study with prospective follow-up included 12 adults with SSD who underwent cochlear implantation between 2015 and 2024 at a tertiary referral center. Assessments included the Danish Sentence Test (DAST), sound localization testing, and patient-reported outcome measures. Speech reception thresholds (SRTs), localization accuracy (RMSE), QoL (NCIQ), and tinnitus burden (THI) were evaluated.

Results: Cochlear implantation significantly improved speech recognition in the head shadow condition, whereas no significant improvements were observed for binaural squelch or summation. Sound localization accuracy improved significantly. Total NCIQ and THI scores also improved significantly.

Conclusions and significance: Cochlear implantation improved speech recognition in noise, sound localization, quality of life, and tinnitus burden in adults with SSD, supporting its use as an effective treatment option for selected patients.

单侧耳聋患者人工耳蜗植入与双耳听力的北欧队列研究。

目的探讨人工耳蜗植入术对成人SSD患者噪声语音识别、声音定位、生活质量及耳鸣的影响。材料和方法：这项前瞻性随访的回顾性队列研究纳入了2015年至2024年间在三级转诊中心接受人工耳蜗植入的12名成年SSD患者。评估包括丹麦语句子测试（DAST）、声音定位测试和患者报告的结果测量。评估语音接收阈值（SRTs）、定位精度（RMSE）、生活质量（NCIQ）和耳鸣负担（THI）。结果：人工耳蜗植入术显著改善了头影条件下的语音识别，而双耳噪声和双耳叠加无显著改善。声音定位精度显著提高。NCIQ和THI总分也显著提高。结论及意义：人工耳蜗植入可改善成人SSD患者的语音识别、声音定位、生活质量和耳鸣负担，支持其作为特定患者的有效治疗选择。
