The aim of this study is to show the long-term effects of cochlear implant as a treatment in both children and adults with acquired single-sided deafness.
Observational, descriptive, cross-sectional.
Tertiary referral center.
21 children and 20 adults with SSD.
Unilateral CI.
Speech detection thresholds and disyllabic words test (65 dB SPL) were performed in the modalities azimuth (S0), signal CI side (SCI), and signal on the normal hearing (SNH). The normal ear was masked with both white noise of +10 dB of the hearing threshold and plugging the same ear, whereas the speech testing was performed using the cochlear implant wireless system.
All results were obtained up to 48 months after the activation of the sound processor. All study subjects showed improvements in speech test results in all conditions tested. Word recognition in noise in children improved from 42.76% at 6 months after activation of the sound processor to 76.38% at 48 months in the S0 condition, from 50 to 78.10% in the SCI condition, and from 38.48 to 66.48% in the SNH modality. Regarding adults, word recognition in noise went from 45.40% at 6 months of activation of the sound processor to 73.40% at 48 months in the S0 condition, from 52.60 to 76.20% in the SCI condition, and from 43.60 to 64.80% in the SCI condition ( p < 0.001). The average duration of use of the speech processor daily was 11 hours in children and 9.4 hours in adults.
When comparing children's performance with adults', progressive improvement in speech discrimination compared with adults was observed.
本研究旨在展示人工耳蜗植入术对获得性单侧耳聋的儿童和成人患者的长期治疗效果。
观察性、描述性横断面研究。
三级转诊中心。
21名患有单侧耳聋的儿童和20名成人。
单侧人工耳蜗植入。
在方位角（S0）、信号来自人工耳蜗侧（SCI）和信号来自正常听力侧（SNH）这几种模式下进行言语检测阈值和双音节词测试（65 dB声压级）。正常耳用高于听力阈值10 dB的白噪声掩蔽并堵塞该耳，而言语测试使用人工耳蜗无线系统进行。
所有结果均在声音处理器激活后48个月内获得。所有研究对象在所有测试条件下言语测试结果均有改善。在S0条件下，儿童在噪声中的单词识别率从声音处理器激活后6个月的42.76%提高到48个月时的76.38%，在SCI条件下从50%提高到78.10%，在SNH模式下从38.48%提高到66.48%。对于成人，在S0条件下，声音处理器激活后6个月时噪声中的单词识别率为45.40%，48个月时为73.40%；在SCI条件下从52.60%提高到76.20%；在SCI条件下从43.60%提高到64.80%（p < 0.001）。儿童每天使用言语处理器的平均时长为11小时，成人则为9.4小时。
与成人相比，儿童在言语辨别方面有渐进性改善。
