Thirty patients complaining about tinnitus were treated by transcutaneous tragal electrical stimulation. The effect of this treatment has been evaluated by BASR recordings before and after treatment. Taking into account the subjective results three groups are described. The first one (10 patients) is relieved of tinnitus. In second and third group the symptoms still exist, whatever the electrode's position (anode or cathode in tragal position). When BASR are studied before the electrical stimulation no inter-subjects difference can be found. After stimulation, the left delta I-V latency is significatively lengthened, and the wave I latency is shortened in the first group. The study of the two other groups do not reveal any difference between the pre- and the post- stimulation evaluation. So the BASR appears to be a good predictive tool for tinnitus suppression by electrical stimulation.
30名主诉耳鸣的患者接受了经皮耳屏电刺激治疗。通过治疗前后的脑干听觉诱发电位（BASR）记录对该治疗效果进行了评估。考虑主观结果，分为三组。第一组（10名患者）耳鸣得到缓解。第二组和第三组症状仍存在，无论电极位置如何（耳屏位置的阳极或阴极）。在电刺激前研究BASR时，未发现个体间差异。刺激后，第一组左三角波I-V潜伏期显著延长，波I潜伏期缩短。对另外两组的研究未发现刺激前和刺激后评估之间存在任何差异。因此，BASR似乎是电刺激抑制耳鸣的良好预测工具。
