The present study was performed on 32 patients in order to investigate the effect of low-power laser on their tinnitus. The patients were divided into two groups. One group received laser therapy and the other was given a placebo procedure. The effect was evaluated by the use of visual analogue scales. Within the patient group transiently evoked otoacoustic emissions (TEOAE) were measured before, during and after therapy. No significant difference between laser and placebo was found in annoyance or loudness of the tinnitus and in changes of TEOAE amplitude. These results indicate that there is no relationship between the effect of low-power laser and changes in cochlear micromechanics.
本研究对32例患者进行，以调查低功率激光对其耳鸣的影响。患者被分为两组。一组接受激光治疗，另一组接受安慰剂治疗。通过视觉模拟量表评估效果。在患者组中，在治疗前、治疗期间和治疗后测量瞬态诱发耳声发射（TEOAE）。在耳鸣的烦恼程度或响度以及TEOAE振幅变化方面，激光组和安慰剂组之间未发现显著差异。这些结果表明，低功率激光的效果与耳蜗微力学变化之间没有关系。
