The aim of this longitudinal study was to explore whether a hearing aid or noise generator would be an effective audiological treatment for blast-induced chronic tinnitus. The amount of satisfaction from different hearing devices (hearing aid, noise generator, or both) during different time periods (1, 6, 12 and 24 months after fitting) was assessed. The 974 subjects enrolled in this study were Iran-Iraq war veterans, suffering from tinnitus for at least 2 years. About 84% of the subjects preferred just a hearing aid. Only 2.7% chose the noise generator, and the others preferred to use both devices. There were no significant differences between the hearing thresholds of the 3 groups. The satisfaction score for the hearing aid and combined devices increased by time but decreased for the noise generator. There was no correlation between the satisfaction score and parameters such as hearing thresholds, audiogram configuration and tinnitus pitch. We concluded that, compared with a noise generator, the most long-lasting treatment for blast-induced tinnitus is a hearing aid. The possible cause for such a performance is probably the recovery of the auditory function and neuroplasticity through the hearing aid.
这项纵向研究的目的是探讨助听器或噪声发生器是否会成为治疗爆炸所致慢性耳鸣的有效听力治疗方法。评估了在不同时间段（佩戴后1、6、12和24个月）使用不同听力设备（助听器、噪声发生器或两者皆用）的满意度。参与本研究的974名受试者为两伊战争退伍军人，患有耳鸣至少2年。约84%的受试者仅偏爱助听器。只有2.7%的人选择了噪声发生器，其他人则更喜欢同时使用这两种设备。三组的听力阈值之间无显著差异。助听器和组合设备的满意度评分随时间增加，但噪声发生器的满意度评分下降。满意度评分与听力阈值、听力图形态和耳鸣音调等参数之间无相关性。我们得出结论，与噪声发生器相比，治疗爆炸所致耳鸣最持久的方法是使用助听器。出现这种情况的可能原因可能是通过助听器实现了听觉功能和神经可塑性的恢复。
