Tinnitus is an apparent sound, perceived in the ear with no stimulus. It has been described as a sound originating from the brain. It affects 17% of the general population. Etiological factors for tinnitus include temporomandibular joint disorders (TMJ, TMD) and Costen's syndrome. The aim of treatment is to eliminate the tinnitus or at least decrease its apparent volume.
In total, 46 patients referred to our department with bilateral subjective tinnitus with TMDs were selected for this study. Low-level laser therapy (LLLT) with an neodymium-doped yttrium aluminum garnet (Nd:YAG) (1064 nm) laser, LLLT with a diode laser (810 nm), and placebo treatment were applied to the patients. There were 15 patients each in the Nd:YAG and placebo groups and 16 patients in the 810 nm diode laser group. LLLT was applied for 10 days, once per day. A visual analog scale (VAS) was used, with values between 0 and 10. VAS scores were recorded before treatment, on the last day of treatment, and 1 month after treatment. The VAS scores were the same on the last day of treatment and 1 month after treatment. The VAS scores before treatment and at 1 month after treatment were compared in a statistical analysis.
There were statistically significant differences in the Nd:YAG laser (p = 0.001) and 810 nm diode laser groups (p = 0.005), but no difference in the placebo group (p = 0.065).
Both the Nd:YAG and 810 nm diode lasers were effective for the treatment of subjective tinnitus related to TMDs.
耳鸣是在无刺激情况下耳部感觉到的一种明显声音。它被描述为源自大脑的声音。耳鸣影响着17%的普通人群。耳鸣的病因包括颞下颌关节紊乱症（TMJ，TMD）和科斯坦综合征。治疗的目的是消除耳鸣或至少降低其明显音量。
本研究共选取了46例因双侧主观性耳鸣伴TMDs而转诊至我科的患者。对患者分别采用掺钕钇铝石榴石（Nd:YAG）（1064nm）激光的低强度激光疗法（LLLT）、二极管激光（810nm）的LLLT以及安慰剂治疗。Nd:YAG组和安慰剂组各有15例患者，810nm二极管激光组有16例患者。LLLT治疗10天，每天1次。使用视觉模拟量表（VAS），取值范围为0至10。在治疗前、治疗最后一天以及治疗后1个月记录VAS评分。治疗最后一天和治疗后1个月的VAS评分相同。在统计分析中比较了治疗前和治疗后1个月的VAS评分。
Nd:YAG激光组（p = 0.001）和810nm二极管激光组（p = 0.005）存在统计学显著差异，但安慰剂组无差异（p = 0.065）。
Nd:YAG激光和810nm二极管激光对治疗与TMDs相关的主观性耳鸣均有效。
