The study aims to evaluate the efficacy of arthrocentesis in the treatment of internal derangement of the temporomandibular joint (TMJ).
Thirty patients with TMJ internal derangement underwent arthrocentesis using saline. Pain using visual analog scale, maximum mouth opening, joint noises and mandible deviation were documented pre-operatively and post-operatively. Patients were followed for 1 year. Statistical analysis of pain was done by Wilcoxon signed Rank's test and dysfunction by students paired t test.
The mean pre-operative pain was 4.8 ± 2.65 and post-operatively at 1 year was 0.27 ± 0.45 with an average decrease of 4.72 (P = 0.000). The mean maximal mouth opening pre-operatively was 29.8 ± 2.35 mm and post-operatively 41.9 ± 2.48 mm at 1 year. The mean increase in the mouth opening was 12.1 ± 3.0 mm (P = 0.000).
Arthrocentesis is simple, minimally invasive procedure with less risk of complications and significant benefits in patients with TMJ internal derangement.
本研究旨在评估关节穿刺术治疗颞下颌关节内紊乱(TMJ)的疗效。
30例颞下颌关节内紊乱患者接受了生理盐水关节穿刺术。术前和术后记录使用视觉模拟量表的疼痛程度、最大开口度、关节弹响和下颌偏斜情况。对患者进行了1年的随访。采用Wilcoxon符号秩检验对疼痛进行统计学分析,采用学生配对t检验对功能障碍进行分析。
术前平均疼痛评分为4.8±2.65,术后1年为0.27±0.45,平均下降4.72(P = 0.000)。术前平均最大开口度为29.8±2.35mm,术后1年为41.9±2.48mm。开口度平均增加12.1±3.0mm(P = 0.000)。
关节穿刺术是一种简单、微创的手术,并发症风险较低,对颞下颌关节内紊乱患者有显著益处。
