Persistent and distressing tinnitus and TMDs may significantly impair the quality of patients' lives. Problems are particularly severe for those who experience both. Although the exact causes of this association are not fully understood, several hypotheses connect TMD conditions with otological symptoms. The systematic review presented involved records published between 1 January 2004 and 27 November 2024, in the databases PubMed, Scopus, and Web of Science, according to the PRISMA guidelines. The search queries included "temporomandibular disorder" and "tinnitus". Inclusion and exclusion criteria were predefined according to PECOS. A risk of bias assessment and meta-analyses were performed. The study's protocol was registered in PROSPERO (CRD42024533293). Eleven studies included in this review fulfilled all the predefined criteria. In a sample of 114,071 tinnitus patients, 50.99% (95% CI: 33.31-68.54) also had coexisting TMDs. Furthermore, tinnitus patients had more than 2.2 times higher odds of having TMDs compared to the control group ( = 0.002 for random effects). The absence of data regarding randomisation, blinding, and sample size justification was the most frequent risk of bias. Tinnitus frequently co-occurs in patients who suffer from TMDs. It is essential to expand the diagnostic evaluation of patients to confirm its presence and assess its impact on their quality of life. Additionally, dental consultation should be considered to evaluate patients about TMD signs and symptoms when suffering from tinnitus.
持续性且令人苦恼的耳鸣和颞下颌关节紊乱症可能会严重损害患者的生活质量。对于同时患有这两种疾病的患者来说，问题尤为严重。尽管这种关联的确切原因尚未完全明确，但有几种假说将颞下颌关节紊乱症与耳科症状联系起来。根据PRISMA指南，本系统评价纳入了2004年1月1日至2024年11月27日期间在PubMed、Scopus和Web of Science数据库中发表的记录。检索词包括“颞下颌关节紊乱症”和“耳鸣”。根据PECOS预先定义了纳入和排除标准。进行了偏倚风险评估和荟萃分析。该研究方案已在PROSPERO（CRD42024533293）中注册。本评价纳入的11项研究均符合所有预先定义的标准。在114,071名耳鸣患者样本中，50.99%（95%CI：33.31 - 68.54）同时患有颞下颌关节紊乱症。此外，与对照组相比，耳鸣患者患颞下颌关节紊乱症的几率高出2.2倍以上（随机效应 = 0.002）。缺乏关于随机化、盲法和样本量合理性的数据是最常见的偏倚风险。耳鸣在患有颞下颌关节紊乱症的患者中经常同时出现。扩大对患者的诊断评估以确认其存在并评估其对生活质量的影响至关重要。此外，当患者患有耳鸣时，应考虑进行牙科咨询以评估其颞下颌关节紊乱症的体征和症状。
