This umbrella review (UR) explored the possible associations between temporomandibular disorders (TMDs) and otologic signs/symptoms (OSs) and established the potential impact of TMD interventions on OSs. A systematic review of systematic reviews (SRs)/meta-analyses (MAs) was conducted according to the PRISMA guidelines and Joanna Briggs Institute UR protocol. Electronic search of the PubMed, Scopus, Web of Science, and Open Grey databases was conducted and the quality of the identified studies was assessed using the AMSTAR2 criteria. Out of 923 and 157 articles screened for the first and second focus questions respectively, a total of 8 SRs/MAs fulfilled the eligibility criteria. The prevalence of OSs in TMD patients and contrariwise varied substantially up to 85.0-95.0%. Available evidence indicates that TMDs are associated with OSs, and TMD treatment reduced OSs. Findings suggest that a comorbid relationship between TMDs and OSs exists, and therapeutic TMD interventions improve OSs.
