背景：一些青少年存在听力障碍，其特征是低频段和中频段（低于 1500 Hz）阈值正常或略有升高，而高频范围几乎完全失聪。这些患者往往仍超出有效助听器治疗的范围。 病例报告：本研究介绍了一名 16 岁青少年的病例，该青少年在 125-1500 Hz 范围内听力良好，但在其他频率范围内耳聋。植入物用于恢复高频听力，同时保留植入耳中的低频和中频听觉。这被描述为内耳自然电刺激 (ENS)。结论：结果表明，使用圆窗手术技术可以保留低频和中频听力（高达 1500 Hz）。当一侧的电刺激与两侧的声刺激相结合时，还观察到言语辨别力的显着改善。可以扩大人工耳蜗植入的资格标准，将适合 ENS 的青少年纳入其中。 (C) 2015 Elsevier Ireland Ltd. 保留所有权利。
Background: Some adolescents have hearing impairments characterized by normal or slightly elevated thresholds in the low and mid-frequency bands (below 1500 Hz) and nearly total deafness in the high frequency range. These patients often remain beyond the scope of effective hearing aid treatment.Case report: This study presents the case of a 16-year-old adolescent with good hearing in the range 125-1500 Hz and deafness at other frequencies. An implant was used to restore hearing at high frequencies, while preserving low and mid frequency acoustic hearing in the implanted ear. This is described as electro-natural stimulation (ENS) of the inner ear.Conclusions: The results demonstrate that low and mid frequency hearing (up to 1500 Hz) can be preserved using the round window surgical technique. A substantial improvement in speech discrimination was also observed when electrical stimulation on one side was combined with acoustic stimulation on both sides. There is scope to extend qualifying criteria for cochlear implantation to include adolescents who are suited to ENS. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
