title: Prevalence of tinnitus in patients with different temporomandibular disorders symptoms.
abstract: OBJECTIVE
  To compare the prevalence of tinnitus in temporomandibular disorder (TMD) patients affected by either jaw muscle pain, temporomandibular joint (TMJ) internal derangements, or TMJ arthrosis.
  
  
  METHODS
  The presence of self-reported tinnitus was assessed in 250 consecutive TMD patients and correlation analysis was performed with clinical TMD signs and symptoms.
  
  
  RESULTS
  Tinnitus prevalence in the TMD population was 30.4%. Any significant patterns of correlation were shown for the overall study group, despite a higher tinnitus prevalence in patients with (32.8%) than without masseter pain (24.8%; p = 0.176) as well as in those with (33.7%) than without TMJ arthrosis (26.1%; p = 0.082). Age-stratified analysis showed correlations with masseter pain in older patients (48.3% vs 16; p < 0.05), and with arthrosis in younger patients (57.1% vs 22.2%; p < 0.05).
  
  
  CONCLUSIONS
  Any correlation patterns were shown between tinnitus and TMD. Age-stratified analysis suggested possible hypotheses for a symptom-specific clinical correlation that should be assessed with future research.
