Abstract:

Objective: To observe the clinical efficacy of closure therapy for myalgia temporomandibular disorder (TMD) in different sites and subtypes. Methods: A retrospective study of 53 patients with myalgia TMD treated with lidocaine and vitamin B₁₂ combined with compound betamethasone topical muscle closed therapy was conducted. The clinical efficacy assessment, maximum mouth opening, jaw movement distance, muscle pressure pain index (PI), and visual analogue scale (VAS) scores before treatment, first and third month after treatment were compared and analyzed. Results: After a course of treatment, the patients' maximum mouth opening and jaw movement distance increased compared with those before treatment (P<0.01), and the PI and VAS scores decreased compared with those before treatment (P<0.01), resulting in a better clinical efficacy. Conclusion: For different sites and subtypes of myalgia TMD, closure therapy can effectively relieve pain and reduce the degree of dysfunction, and this treatment method has certain clinical value.

摘要：

目的: 观察封闭治疗对不同部位、不同亚类肌痛型颞下颌关节紊乱病（temporomandibular disorder，TMD）的临床疗效。方法: 回顾性研究肌痛型TMD患者53例，给予利多卡因、维生素B₁₂联合复方倍他米松局部肌肉封闭治疗，对比分析治疗前、治疗后第1、3个月的临床疗效评价，最大开口度，下颌运动距离，肌肉压痛指数（palpation index，PI），视觉模拟评分法（visual analogue scale，VAS）评分。结果: 经过1个疗程的治疗，患者最大开口度、下颌运动距离较治疗前增加（P<0.01），PI及VAS评分较治疗前降低（P<0.01），临床疗效较好。结论: 对于不同部位、不同亚类的肌痛型TMD，封闭治疗能有效缓解疼痛、减轻功能障碍程度，该诊疗方法具有一定的临床价值。
