Since the first description of tinnitus retraining therapy (TRT), clinicians have modified and customised the method of TRT in order to suit their practice and their patients. A simplified form of TRT is used at Ealing Primary Care Trust Audiology Department. Simplified TRT is different from TRT in the type and (shorter) duration of the counseling but is similar to TRT in the application of sound therapy except for patients exhibiting tinnitus with no hearing loss and no decreased sound tolerance (wearable sound generators were not mandatory or recommended here, whereas they are for TRT). The main goal of this retrospective study was to assess the efficacy of simplified TRT.
Data were collected from a series of 42 consecutive patients who underwent simplified TRT for a period of 3 to 23 months. Perceived tinnitus handicap was measured by the Tinnitus Handicap Inventory (THI) and perceived tinnitus loudness, annoyance and the effect of tinnitus on life were assessed through the Visual Analog Scale (VAS).
The mean THI and VAS scores were significantly decreased after 3 to 23 months of treatment. The mean decline of the THI score was 45 (SD = 22) and the difference between pre- and post-treatment scores was statistically significant. The mean decline of the VAS scores was 1.6 (SD = 2.1) for tinnitus loudness, 3.6 (SD = 2.6) for annoyance, and 3.9 (SD = 2.3) for effect on life. The differences between pre- and post-treatment VAS scores were statistically significant for tinnitus loudness, annoyance, and effect on life. The decline of THI scores was not significantly correlated with age and duration of tinnitus.
The results suggest that benefit may be obtained from a substantially simplified form of TRT.
自从首次描述耳鸣再训练疗法（TRT）以来，临床医生对TRT方法进行了修改和定制，以适应他们的临床实践和患者需求。伊灵初级保健信托听力科采用了一种简化形式的TRT。简化TRT在咨询类型和（较短的）持续时间上与TRT不同，但在声音疗法的应用方面与TRT相似，不过对于没有听力损失且声音耐受性没有降低的耳鸣患者除外（此处不强制或推荐使用可穿戴声音发生器，而TRT则需要）。这项回顾性研究的主要目的是评估简化TRT的疗效。
收集了连续42例接受简化TRT治疗3至23个月患者的资料。通过耳鸣障碍量表（THI）测量耳鸣所致的主观障碍，通过视觉模拟量表（VAS）评估耳鸣的主观响度、烦恼程度以及耳鸣对生活的影响。
治疗3至23个月后，THI和VAS的平均得分显著降低。THI得分的平均下降值为45（标准差 = 22），治疗前后得分差异具有统计学意义。VAS得分的平均下降值在耳鸣响度方面为1.6（标准差 = 2.1），烦恼程度方面为3.6（标准差 = 2.6），对生活的影响方面为3.9（标准差 = 2.3）。治疗前后VAS得分在耳鸣响度、烦恼程度以及对生活的影响方面的差异具有统计学意义。THI得分的下降与年龄和耳鸣持续时间无显著相关性。
结果表明，一种大幅简化形式的TRT可能会带来益处。
