Application of arthrocentesis in temporomandibular joint disorders preferred and suggested therapeutic treatment option in recent years. This study was designed to investigate and compare the effect of intra-articular injection of botulinum toxin-A (Btx-A) on pain and mouth opening after arthrocentesis in nonreduction disc displacement.
This restrospective study was conducted on 30 patients with a visual analogue scale is higher than five and limited mouth opening. Patients were divided into 2 groups as conventional arthrocentesis group (group A) and intra-articular Btx-A injection following arthrocentesis group (group B). Maximum mouth openining and temporomandibular joint pain were measured in preoperative (t0) and at postoperative 1-week (t1), 1-month (t2) and 6-month (t3).
When VAS scores of group A and group B were examined, no statistical difference was observed at t0 and t1 time intervals; an increased in mouth opening values and decreased VAS score values were observed in both groups in the 1 month (t2) and 6t3) months, mostly in group A.
İntra-articular injection of Btx-A following arthrocentesis can induce mouth opening and reduce the pain and dysfunction in patients with anterior disc displacement.
近年来，关节穿刺术已成为治疗颞下颌关节紊乱的首选方法。本研究旨在探讨和比较关节内注射肉毒毒素 A（Btx-A）对不可复性盘前移位患者关节穿刺术后疼痛和张口度的影响。
本回顾性研究纳入了 30 名视觉模拟评分高于 5 分且张口受限的患者。患者分为常规关节穿刺术组（A 组）和关节穿刺术后关节内注射 Btx-A 组（B 组）。术前（t0）、术后 1 周（t1）、1 个月（t2）和 6 个月（t3）测量最大张口度和颞下颌关节疼痛。
在 t0 和 t1 时间点，A 组和 B 组的 VAS 评分无统计学差异；两组在 1 个月（t2）和 6 个月（t3）时，张口度增加，VAS 评分降低，A 组更为明显。
关节内注射 Btx-A 可增加张口度，减轻不可复性盘前移位患者的疼痛和功能障碍。
