目的:评价手术治疗颞下颌关节盘移位的方法和近期疗效。方法:2009年10月—2010年9月间手术治疗颞下颌关节盘移位患者9例(11侧),其中男1例、1侧,女8例、10侧,平均年龄28.4岁,术前平均开口度21.3mm。术前均行磁共振检查,明确诊断和分期,4例(5侧)行关节镜手术,5例(6侧)行关节盘锚固定术。术后进行至少3个月的临床随访和磁共振检查。结果:所有患者手术切口均一期愈合,未发生永久性面瘫等严重并发症,随访期末,平均开口度为32.8mm,磁共振复查显示关节盘髁关系保持稳定。结论:通过完善术前检查,严格掌握手术适应证,2种手术方法治疗颞下颌关节盘移位均有良好疗效。
Objective: To evaluate the surgical treatment of temporomandibular joint disc displacement method and short-term efficacy. Methods: Nine patients (11 sides) with temporomandibular joint disc displacement underwent surgical treatment from October 2009 to September 2010, including 1 males and 1 females, 8 females and 10 sides with an average age of 28.4 years. The average opening of 21.3mm. MRI was performed preoperatively to confirm the diagnosis and staging. Arthroscopic surgery was performed in 4 cases (5 sides) and arthrodesis in 5 cases (6 sides). Postoperative at least 3 months of clinical follow-up and magnetic resonance imaging. Results: All patients underwent primary incision healed without serious complications such as permanent facial paralysis. At the end of the follow-up period, the average opening degree was 32.8mm. Magnetic resonance examination showed that the relationship of the condyle remained stable. Conclusion: By improving the preoperative examination and strictly controlling the operation indications, the two kinds of surgical methods have a good effect in the treatment of temporomandibular joint disc displacement.
