• Complaints of diminished hearing or reduced speech discrimination frequently accompany temporomandibular dysfunction. There is no consensus as to the mechanism of their occurrence or the alteration of these symptoms with the treatment. We studied 12 subjects with internal derangement of the temporomandibular joint (treated surgically) and nine subjects with myofascial pain disorder (treated medically), and we found no difference between the groups in pretreatment audiometric findings or in their degree of otologic symptoms. Similarly, there were no differences in posttreatment audiometric measures and there were no significant treatment effects. Furthermore, there was no correlation between subjects' complaints of reduced hearing sensitivity or discrimination and audiometric results. The apparently significant reduction in symptoms experienced by some subjects in the absence of audiometric change suggests the operation of unmeasured factors in their response to treatment.
