透明质酸钠关节腔注射联合牙合垫治疗不可复性关节盘前移位的疗效评价

目的:评价关节腔注射透明质酸钠联合稳定性牙合垫治疗颞下颌关节不可复性盘前移位的临床疗效。方法:将在郑州市口腔医院就诊的40例不可复性盘前移位的患者随机分为实验组和对照组,实验组采用关节上腔注射透明质酸钠联合稳定性牙合垫治疗,对照组采用单纯的关节上腔注射透明质酸钠治疗,对比分析两组患者在治疗前、治疗后、治疗后3个月、6个月时的Friction颞下颌关节紊乱指数、疼痛视觉模拟评分(VAS)和最大开口度。结果:两组患者治疗后开口度、疼痛程度及颞下颌关节紊乱症状及体征与术前比较均明显改善,差异均有统计学意义(P<0.05)。实验组与对照组患者治疗后同时点比较,张口度差异不明显(P>0.05)。实验组患者治疗后及治疗后3、6个月时VAS、颞下颌关节紊乱指数(craniomandibular index ,CMI)和颞下颌关节功能障碍指数(dysfunction index , DI)低于对照组,差异均有统计学意义(P<0.05)。结论:关节上腔注射透明质酸钠联合牙合垫治疗颞下颌关节不可复性盘前移位疗效优于单纯的关节上腔注射治疗透明质酸钠。

Effect of Sodium Hyaluronateacid (Sh) Injection Combined with Occlusal Splint on Temporomandibular Joint Anterior Disc Displacement without Reduction

Objective: To evaluate the efficacy of sodium hyaluronateacid(SH) injection combined with stabilizationsplint for the treatment of anterior disc displacement without reduction. Methods: Forty patients with temporomandibular joint anterior disc displacement without reduction were randomly divided into the experimental group and the control group. The experimental group wasinjected withSH in the articular cavity combined with stabilizationsplint, and the control group was only injected with SH in the articular cavity. Comparative analysis was performed before, 3 months, and 6 months after treatment in patients withFricton dysfunction index, pain index(VAS) and maximal mouth opening. Results: After treatment, temporomandibular dysfunction,arthralgia and mouth openingof patients in the two groups weresignificantly improved(P<0.05). No significant difference ofthe mouth opening was found between two groups (P>0.05). The VAS,CMI and DI of the experimental group decreased significantly than those of the control group (P<0.05). Conclusion: Intraarticular injection of SH combined with stabilizationsplint for the treatment of anterior disc displacement without reduction is betterthan the simple articular cavity injection of SH.
