To compare clinical and imaging results of two needles arthrocentesis (TNA) versus double-needle cannula arthrocentesis (DNCA) in the treatment of temporomandibular joint disc displacement (DD).
Twenty patients with DD were randomly divided into two groups: TNA and DNCA. Clinical data (pain scores; maximal interincisal distance [MID], and protrusion and laterality movements) were evaluated before and 24 months after the arthrocentesis. Disc and condyle position and joint effusion (JE) were evaluated by magnetic resonance exams.
Both groups presented improvement in the MID, including pain reduction, modifications in disc and condyle positions, and reduction of the presence of JE, without difference between groups ( > 0.05). The DNCA was performed significantly faster ( = 0.0001).
Both TNA and DNCA are efficient in promoting improvement in the MID: reduction in pain, modifications in disc and condyle positions, and, in part, may account for less JE, without difference between techniques.
比较双针关节穿刺术（TNA）与双针套管关节穿刺术（DNCA）治疗颞下颌关节盘移位（DD）的临床和影像学结果。
20例DD患者随机分为两组：TNA组和DNCA组。在关节穿刺术前和术后24个月评估临床数据（疼痛评分、最大切牙间距离[MID]、前伸和侧方运动）。通过磁共振检查评估盘和髁突位置以及关节积液（JE）。
两组的MID均有改善，包括疼痛减轻、盘和髁突位置改变以及JE减少，两组间无差异（>0.05）。DNCA的操作明显更快（=0.0001）。
TNA和DNCA在促进MID改善方面均有效：疼痛减轻、盘和髁突位置改变，部分可能是JE减少，两种技术之间无差异。
