听觉系统的电声联合刺激（EAS）是一种新的治疗方法，用于治疗严重至极深的高频和中频听力损失但仍有低频听力的患者。在一项前瞻性研究中，13名低频听力优于1 kHz以下60 dB的患者植入了MED- EL COMBI 40+人工耳蜗。在安静和噪声环境下，分别测量了助听器、人工耳蜗单独和联合刺激模式（EAS）下的纯音听阈、单音节词得分和Hochmair-Schulz- Moser语句。13例患者中11例听力部分保留。所有患者单独使用人工耳蜗的评分均显著高于使用助听器。7名患者在EAS模式下的噪音句子评分高于单独使用人工耳蜗，4名保持不变，2名无法使用EAS。EAS的协同效应对于噪音中的听力最为突出，与单独植入人工耳蜗相比，提高了高达72%。版权所有（C）2005 S.

Combined electric and acoustic stimulation ( EAS) of the auditory system is a new therapy for patients with severe to profound high- and mid- frequency hearing loss but remaining low- frequency hearing. In a prospective study, 13 patients with low- frequency hearing of better than 60 dB below 1 kHz were implanted with a MED- EL COMBI 40+ cochlear implant. Pure tone thresholds as well as monosyllabic word scores and Hochmair- Schulz- Moser sentences in quiet and in noise were measured with hearing aids, cochlear implant alone and in the combined stimulation mode ( EAS) in the same ear. Hearing could be partially preserved in 11 out of the 13 patients. All patients scored significantly higher with cochlear implant alone than with hearing aids. Seven patients scored higher in the EAS mode than with cochlear implant alone for sentences in noise, 4 remained unchanged, and 2 could not use EAS. Synergistic effects of EAS were most prominent for hearing in noise with increases of up to 72% as compared to cochlear implant alone. Copyright (C) 2005 S. Karger AG, Basel.
