一种刺激耳朵和舌头的装置可在长达1年的时间内显著降低326名患者耳鸣症状的严重程度,并同时获得了患者的高满意度和依从性。这项研究是迄今为止最大规模的治疗耳鸣的临床试验之一;它表明,双模式方法有可能提供首个行之有效且在临床上可行的耳鸣治疗装置;有多达15%的人口罹患耳鸣。这种恼人的听觉障碍表现在当患者在没有任何外部输入的情况下会有幻听(例如铃声)的感觉。尽管它具有很高的患病率并会令人失能,但仍无得到批准的医疗装置或药物治疗可以减轻病人的痛苦。但是,近来的动物研究显示,通过声音和电来刺激听觉神经系统可以改善症状。基于这些令人看好的结果,Brendan Conlon和同事使用了一种无创性刺激装置;它能通过耳机将声音传入耳朵,并用少量的电来刺激舌头。在对326名罹患不同类型耳鸣病人所做的随机试验中,作者指示患者每天使用该装置60分钟,持续12周。该装置减轻了耳鸣症状,而且这些改善在整个12个月的随访期内持续存在。没有一个患者出现任何严重的副作用;据作者报告,患者有很高的满意度,因为在给予反馈的患者中有77.8%的人会说,他们愿意向认识的耳鸣患者推荐这种治疗方法。该研究小组指出,他们目前正在进行另一项大型临床试验,旨在研究随时间推移而改变刺激方案的功效。
