Audiometric assessment of patients with painful TMJ internal derangements: failure of audiometry to change following arthrotomy.
Thirteen patients with proven internal derangements of 16 temporomandibular joints were scheduled for arthrotomy. The patients' perception of otologic symptoms were recorded before surgery, and hearing was evaluated audiometrically both before and after surgery. There was no significant correlation between otologic symptoms and ipsilateral painful internal derangement of the temporomandibular joint. Perceived hearing loss was substantiated in only about half of the instances. Further, only about half of the ears with measured hearing loss (sensorineural) were associated with a painful internal derangement. Arthrotomy did not change any of the audiograms.
