Several techniques have been used to treat chronic dislocation of the mandible. Most of these techniques represent attempts at reducing the mobility of the TMJ. The eminectomy procedure is an attempt at restoring normal joint function without reducing mobility of the joint. We have presented two cases of chronic dislocation of the mandible that were treated successfully by removal of the articular tubercle and the lateral portion of the temporal bone. Although surgery of the TMJ area may be hazardous if approached without caution, we feel that the complications associated with this procedure are minimized if adequate care is taken in flap design and tissue dissection. On the basis of the excellent results of the eminectomy procedures reported in the literature and of our own experience with this procedure, we feel that this is the preferred treatment for chronic dislocation of the mandible.
已经采用了多种技术来治疗下颌骨慢性脱位。这些技术大多旨在减少颞下颌关节的活动度。关节结节切除术是一种在不降低关节活动度的情况下恢复正常关节功能的尝试。我们报告了两例下颌骨慢性脱位病例，通过切除关节结节和颞骨外侧部分成功治愈。尽管颞下颌关节区域的手术如果操作不慎可能有风险，但我们认为，如果在皮瓣设计和组织解剖时给予充分注意，与该手术相关的并发症可降至最低。基于文献中报道的关节结节切除术的良好效果以及我们自己的经验，我们认为这是治疗下颌骨慢性脱位的首选方法。
