“…Two studies that included bruxism reported a prevalence of tinnitus of over 50% which could indicate that TMD in combination with bruxism have a higher degree of comorbidity with tinnitus compared with TMD alone. The highest prevalence of tinnitus, 70%, was reported in a study with predominately female population . The higher prevalence of tinnitus in the included female‐only studies is in agreement with studies reporting higher prevalence of tinnitus for women with TMD, although the prevalence of tinnitus in the general population is higher in men.…”

“…To compare results, it is important that studies have used standardised diagnostic systems. Fourteen of the 26 included studies used the RDC/TMD while the other 12 used non‐validated questionnaires, which creates uncertainty about the TMD diagnoses . In all included studies, tinnitus is self‐reported; tinnitus can, however, also be classified using the THI .…”

The aim of this systematic review was to evaluate the prevalence of tinnitus in patients with temporomandibular disorders (TMD) and the possible effects of TMD treatment on tinnitus symptoms. A search of the PubMed, Web of Science and Cochrane databases from inception of each database up to January 2017 found 222 articles. After independent screening of abstracts by two of the authors, we assessed 46 articles in full text. The inclusion and exclusion criteria reduced these to 25 articles of which 22 studies reported prevalence based on 13 358 patients and 33 876 controls, and eight studies reported effect of TMD treatment on tinnitus based on 536 patients and 18 controls. The prevalence of tinnitus in patients with TMD varied from 3.7% to 70% (median 42.3%) whereas the prevalence in control groups without TMD varied between 1.7% and 26% (median 12%). The eight treatment studies indicated that treatment of TMD symptoms may have a beneficial effect on severity of tinnitus. However, only one treatment study included a control group, meaning that the overall level of evidence is low. The finding that tinnitus is more common in patients with TMD means that it can be regarded as a comorbidity to TMD. However, in view of the lack of evidence currently available, further well-designed and randomised studies with control groups are needed to investigate whether possible mechanisms common to tinnitus and TMD do exist and whether TMD treatment can be justified to try to alleviate tinnitus in patients with TMD and comorbidity of tinnitus.

“…However, other studies 7,37,38 showed audiometric thresholds within normal limits. In this sense, the hearing findings in patients with TMD are unclear and need to be better examined.…”

“…The retrospective study (27) comprised 30 patients with diagnosed dentofacial deformities and TMD, males and females, between 18 and 49 years of age, undergoing clinical assessment (muscle palpation, temporomandibular joint auscultation during the mandibular motions and measurement of mandibular motion), audiological testing (audiometric tonal threshold and imitanciometry) and two questionnaires, being one on otological and vestibular symptoms and other related to the TMD. Results evidenced absence of disorders in the audiological and imitanciometric testing to all the assessed subjects.…”

RESUMO Objetivo Analisar os achados audiológicos em indivíduos com desordem temporomadibular e comparar esses achados com indivíduos sem desordem temporomanbibular. Métodos A amostra foi composta por 39 participantes adultos, de ambos os gêneros, com diagnóstico prévio de desordem temporomandibular (grupo de estudo) e 39 participantes adultos, sem desordem temporomandibular (grupo controle). Todos os participantes foram submetidos à audiometria tonal limiar em altas frequências, imitanciometria e pesquisa das emissões otoacústicas evocadas por produto de distorção. Resultados Observou-se prevalência de desordem temporomandibular no gênero feminino e a média de idade ficou acima da quarta década de vida. Na audiometria tonal limiar, foi observada ocorrência de perda auditiva do tipo neurossensorial e condutiva, no grupo de estudo, além de piores limiares auditivos em altas frequências. Em ambos os grupos, houve maior ocorrência de curva timpanométrica do tipo A, bem como diferenças entre os grupos na pesquisa do reflexo acústico ipsilateral e contralateral e no registro das emissões otoacústicas evocadas por produto de distorção. Conclusão Indivíduos com desordem temporomandibular apresentam piores resultados nos limiares auditivos, na timpanometria, nos reflexos acústicos ipsilaterais e contralaterais e nas emissões otoacústicas evocadas, quando comparados com o grupo controle.
