Eminectomy with or without a subsequent discoplasty was performed on 30 patients (36 joints) with internal derangement of the temporomandibular joint (TMJ) confirmed either arthrographically or with magnetic resonance imaging. The importance of the inclination of the TMJ eminence and the therapeutic value of eminectomy are discussed. The TMJs were clinically evaluated before and at least 1 year after surgery in respect to opening function and symptoms. The results were promising (86.8% of the patients felt better). In five patients with a preoperative diagnosis of anterior disc displacement with reduction, only an eminectomy was performed. In these five cases eminectomy alone was sufficient to restore normal TMJ function.
对30例（36个关节）经关节造影或磁共振成像确诊为颞下颌关节（TMJ）内紊乱的患者进行了乙状窦前壁切除术，部分患者随后还进行了椎间盘成形术。讨论了TMJ髁突倾斜度的重要性以及乙状窦前壁切除术的治疗价值。术前及术后至少1年对TMJ的开口功能和症状进行临床评估。结果令人满意（86.8%的患者感觉好转）。术前诊断为可复性盘前移位的5例患者仅接受了乙状窦前壁切除术。在这5例病例中，仅乙状窦前壁切除术就足以恢复TMJ的正常功能。
