目的探讨关节腔注射透明质酸钠治疗间接性颞下颌关节(TMJ)损伤后并发关节功能紊乱患者的临床疗效。方法选择2009年5月至2011年5月甘肃省嘉峪关市第一人民医院口腔科收治的因间接性TMJ损伤并发关节功能紊乱且经保守治疗无效的患者40例,将其随机分为两组:治疗组20例,关节腔冲洗后注射透明质酸钠;对照组20例,单纯行关节腔冲洗。观察两组患者治疗前后关节疼痛、开口度和侧向活动度的变化。结果经过1个疗程(每周1次,3周为1个疗程)治疗后,两组患者的关节疼痛、开口度和侧向活动度均较治疗前改善;组间比较结果显示,治疗组关节疼痛、开口度和侧向活动度的改善程度均较对照组明显,差异有统计学意义(P<0.01)。结论关节腔注射透明质酸钠治疗间接性TMJ损伤后并发关节功能紊乱病的疗效优于单纯进行关节腔冲洗;透明质酸钠可以明显改善间接性TMJ损伤并发关节功能紊乱患者的疼痛症状、开口度和侧向活动度。
Objective To investigate the clinical effect of intra-articular injection of sodium hyaluronate in the treatment of patients with congenital joint dysfunction after indirect temporomandibular joint (TMJ) injury. Methods From May 2009 to May 2011, 40 cases of indirect TMJ injury complicated with joint dysfunction treated by Department of Stomatology, First People’s Hospital of Jiayuguan City, Gansu Province were randomly divided into two groups: In the treatment group, 20 cases were treated with intra-articular injection of sodium hyaluronate. In the control group, 20 cases were treated with simple intra-articular irrigation. The changes of joint pain, opening degree and lateral activity before and after treatment were observed in two groups of patients. Results After a course of treatment (once a week, once a week for 3 weeks), the pain, opening degree and lateral motion of the two groups were improved compared with those before treatment. Comparisons between groups showed that the joint of the treatment group The degree of improvement of pain, opening degree and lateral activity were significantly higher than that of the control group (P <0.01). Conclusion Intra-articular injection of sodium hyaluronate for the treatment of indirect TMJ injury is more effective than concurrent joint flushing in the treatment of joint dysfunction. Sodium hyaluronate can significantly improve the pain symptoms in patients with indirect TMJ injury and joint dysfunction. Degree and lateral activity.
