透明质酸钠关节下腔注射治疗颞下颌关节盘前移位的疗效分析

目的：探讨透明质酸钠治疗颞下颌关节盘前移位的临床疗效。方法：50例患者临床表现与核磁共振成像检查确诊为颞下颌关节盘前移位（可复性或不可复性）,进行关节下腔灌洗及透明质酸钠注射治疗.观察分析治疗前、治疗1、2、3次和治疗后3个月临床疗效和Helkimo指数分析。结果：治疗1、2、3次、治疗后3个月与治疗前相比较,临床疗效及Helkimo指数差异有统计学意义（P〈0.05）,治疗3次与治疗后3个月差异无统计学意义。结论：应用透明质酸钠关节腔注射治疗颞下颌关节盘前移位具有良好的效果,治疗效果稳定。

Inferior Articular Cavity Injection of Sodium Hyaluronate in the Treatment of Anterior Temporomandibular Joint Disc Displacement

Objective： To investigate the clinical efficacy of the sodlum iayanuronare injection in the terior temporomandibular joint （TMJ） disc displacement. Methods： Fifty cases with anterior TMJ disc displacement （with reduction or without reduction） were diagnosed by the magnetic resonance imaging （MRI） before manage- ment. All cases were treated with inferior articular cavity lavage of 2~ lidocaine and injection of sodium hyalur- onate. The treatment was performed for three times in every two weeks. Clinical features were evaluated before the treatment, after every injection and in the followed--up three months. HeIkimo analysis was also applied to evaluate the function of TMJ before and after the treatment. Results： The clinical symptoms and Helkimo index of all the ca- ses had been improved significantly after treatment （P~0.05）. The Helkimo index improved significantly with the prolongation of treatment. But there was no statistical difference of Helkimo index among the cases between the third injection and the post--treatment 3m. Conclusion： It suggested that the inferior articular cavity injection of so- dium hyaluronate might be an effective therapy for anterior TMJ disc displacement with or without reduction.
