211 cases of temporomandibular joint pain/dysfunction syndrome treated by condylotomy were traced. 172 operations were investigated by questionnaire and 119 patients examined clinically and radiographically. Operated patients constituted less than 3% of all patients with the syndrome. 91% were cured or improved by surgery. The anatomical structure involved in the technique and operative complications, are discussed. Principal effects of surgery were to produce an increase in radiographic joint space and shortening of the ramus with minimal long term change in the position of the condylar head from its postoperative position. The clinical findings as regards remodelling were confirmed and investigated histologically in a primate model. The mechanisms of pain production in the temporomandibular joint pain/dysfunction syndrome are discussed.
对211例采用髁突切除术治疗的颞下颌关节疼痛/功能障碍综合征患者进行了随访。通过问卷调查对172例手术进行了调查，并对119例患者进行了临床和影像学检查。接受手术的患者占该综合征所有患者的比例不到3%。91%的患者通过手术治愈或改善。文中讨论了该技术所涉及的解剖结构和手术并发症。手术的主要效果是使影像学上的关节间隙增加，下颌支缩短，髁突头部位置从术后位置起的长期变化最小。在灵长类动物模型中对有关重塑的临床发现进行了组织学确认和研究。文中还讨论了颞下颌关节疼痛/功能障碍综合征中疼痛产生的机制。
