Cochlear implants improve the hearing abilities of individuals with unilateral hearing loss and no tinnitus. The benefit is no different from that seen in patients with unilateral hearing loss and incapacitating tinnitus.
To evaluate hearing outcomes after cochlear implantation in individuals with unilateral hearing loss and no tinnitus and compare them to those obtained in a similar group who had incapacitating tinnitus.
Six cases who did not experience tinnitus before operation and 15 subjects with pre-operative tinnitus were evaluated with a structured interview, a monosyllabic word test under difficult listening situations, a sound localization test, and an APHAB (abbreviated profile of hearing aid benefit) questionnaire.
All subjects used their cochlear implant more than 8 hours a day, 7 days a week. In 'no tinnitus' patients, mean benefit of cochlear implantation was 19% for quiet speech, 15% for speech in noise (with the same signal-to-noise ratio in the implanted and non-implanted ear), and 16% for a more favourable signal-to-noise ratio at the implanted ear. Sound localization error improved by an average of 19°. The global score of APHAB improved by 16%. The benefits across all evaluations did not differ significantly between the 'no tinnitus' and 'tinnitus' groups.
人工耳蜗可改善单侧听力损失且无耳鸣患者的听力。其益处与单侧听力损失且伴有致残性耳鸣的患者所见益处无异。
评估单侧听力损失且无耳鸣患者人工耳蜗植入后的听力结果,并将其与类似的伴有致残性耳鸣的患者群体所获得的结果进行比较。
对6例术前未出现耳鸣的患者和15例术前有耳鸣的受试者进行了结构化访谈、在困难听力情况下的单音节词测试、声音定位测试以及APHAB(助听器益处简表)问卷评估。
所有受试者每周7天、每天使用人工耳蜗超过8小时。在“无耳鸣”患者中,人工耳蜗植入在安静环境下言语的平均益处为19%,噪声环境下言语的平均益处为15%(植入耳和未植入耳的信噪比相同),植入耳更有利信噪比时的平均益处为16%。声音定位误差平均改善了19°。APHAB的总体得分提高了16%。“无耳鸣”组和“耳鸣”组在所有评估中的益处无显著差异。
