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.
13例经证实有16个颞下颌关节内紊乱的患者被安排接受关节切开术。在手术前记录患者的耳科症状感知情况，并在手术前后通过听力测定评估听力。耳科症状与同侧颞下颌关节疼痛性内紊乱之间无显著相关性。仅约一半的病例证实有感知性听力损失。此外，在有测量听力损失（感音神经性）的耳朵中，仅约一半与疼痛性内紊乱有关。关节切开术未改变任何听力图。
