Several studies in the literature investigated the association between temporomandibular disorders (TMD) and otogenous symptoms, like vertigo, tinnitus, otalgia and muffling, although the question of the existence of a cause-effect relationship is still controversial. Epidemiological findings showed that the prevalence of ear symptomatology in the general population is variable from 10% to 31%, and increases up to 85% in TMD patients. Based on these data, many attempts have been performed to describe the physiopathological interactions between aural symptoms and TMD, as a strict anatomical link exists between the structures of the ear and those of the stomatognathic system. Unfortunately, methodological weaknesses of most studies are evident so that the comparison of results is often difficult. Considering these premises, the present study critically reviewed the literature on this debated issue, discussing the main etiopathogenetic hypotheses, the features of ear symptomatology in TMD patients and its relationship with TMD treatment in order to present current suggestions about the relationship between aural and TMD symptoms. Suggestions for future researches have been also presented, since a full understanding of this plausible interaction will be an important factor in diagnosis making and treatment planning for both pathologies.
文献中的多项研究调查了颞下颌关节紊乱病（TMD）与耳源性症状之间的关联，如眩晕、耳鸣、耳痛和听力减退，尽管因果关系是否存在这一问题仍存在争议。流行病学研究结果表明，普通人群中耳部症状的患病率在10%至31%之间变化，而在TMD患者中这一比例则高达85%。基于这些数据，人们进行了许多尝试来描述耳部症状与TMD之间的生理病理相互作用，因为耳部结构与口颌系统结构之间存在紧密的解剖学联系。不幸的是，大多数研究的方法学缺陷很明显，因此结果比较往往很困难。考虑到这些前提，本研究对关于这一有争议问题的文献进行了批判性综述，讨论了主要的病因发病学假说、TMD患者耳部症状的特点及其与TMD治疗的关系，以便就耳部症状与TMD症状之间的关系提出当前的建议。还提出了对未来研究的建议，因为充分理解这种可能的相互作用将是这两种疾病诊断和治疗计划中的一个重要因素。
