title: Prevalence of otologic signs and symptoms in adult patients with temporomandibular disorders: a systematic review and meta-analysis.
abstract: OBJECTIVE
  This study aims to estimate the prevalence of otologic signs and symptoms in adult patients with temporomandibular disorders (TMD).
  
  
  METHODS
  Search strategies were developed for each of the following databases: PubMed, LILACS, Scopus, Web of Science, Proquest, LIVIVO, and Google Scholar and OpenGrey was used to assess the grey literature. It was included in this review only observational studies using either research diagnostic criteria (RDC)/TMD or DC/TMD indexes were selected. The Critical Appraisal Checklist for Studies Reporting Prevalence Data from the Joanna Briggs Institute was used to assess the risk of bias of the included studies. A proportion random effects meta-analysis was conducted within the eight included studies.
  
  
  RESULTS
  Eight studies met the eligibility criteria and were selected. All of the included studies used the RDC/TMD and report associated otologic signs and symptoms. The studies were clustered into groups based on prevalence for each individual sign or symptom. The most prevalent otologic symptom associated with TMD was ear fullness (74.8 % standard deviation (SD), 43.02 to 96.25 %; n = 50), followed by otalgia (55.1 % SD, 31.78 to 77.30; n = 386), tinnitus (52.1 % SD, 38.43 to 65.74; n = 1293), vertigo (40.8 % SD, 11.29 to 74.72; n = 374), and hearing loss (38.9 % SD, 2.83 to 85.46; n = 744).
  
  
  CONCLUSIONS
  The prevalence of otologic signs and symptoms in adult patients with TMD is high. The most prevalent otologic symptom in patient adults with TMD is ear fullness.
  
  
  CONCLUSIONS
  This study intends to provide understanding over the prevalence of otologic signs and symptoms in TMD cases in adults.
