title: Tinnitus in individuals without hearing loss and its relationship with temporomandibular dysfunction.
abstract: Research has shown that dysfunction of the temporomandibular joint is often associated with tinnitus.
  
  
  OBJECTIVE
  To characterize tinnitus in individuals with normal hearing and search for a possible relationship with Temporomandibular Disorders (TMD).
  
  
  METHODS
  prospective and cross-sectional.
  
  
  METHODS
  The participants included 20 adults of both genders with tinnitus and normal hearing thresholds on audiometry. We studied tinnitus psychoacoustic characteristics and employed the checklist of TMD signs and symptoms from the Tinnitus Handicap Inventory (THI).
  
  
  RESULTS
  The high pitch, continuous and bilateral tinnitus was the most frequent. Upon acuphenometry, the average tinnitus pitch reported by the subjects was 8.6 kHz and the average loudness was 14.1 dBSL. The degree of discomfort caused by tinnitus was mild. We observed that the higher the pitch, the lower was the loudness and the higher was the THI score. We found that 90% of the patients had at least one TMD sign or symptom.
  
  
  CONCLUSIONS
  The most common was the high pitch, continuous and bilateral tinnitus; 90% of patients had at least one sign or symptom of TMD and there was no correlation between the tinnitus and acuphenometry, THI and the TMD checklist.
