The purpose of this study was to evaluate the clinical outcome and magnetic resonance imaging (MRI) changes of patients with temporomandibular joint (TMJ) internal derangement before and after performance of arthrocentesis and stabilization splint therapy.
Thirty-three patients with unilateral TMJ internal derangement that was successfully treated were included in this study. The clinical outcome and changes in the disc position, disc mobility, disc morphology, joint effusion, bone marrow edema pattern in the mandibular condyle, and the degenerative change before and after arthrocentesis and stabilization splint therapy were compared using MRI.
The average maximum mouth opening (MMO) was increased and the average pain during MMO was decreased significantly after treatment. The disc position, disc mobility, and joint effusion were significantly improved after treatment.
The results in this study indicate that arthrocentesis and stabilization splint therapy provide significant improvement in the clinical outcome, disc position, disc mobility and joint effusion.
本研究的目的是评估颞下颌关节（TMJ）内紊乱患者在进行关节穿刺和稳定型咬合板治疗前后的临床结果和磁共振成像（MRI）变化。
本研究纳入了33例成功治疗的单侧TMJ内紊乱患者。使用MRI比较关节穿刺和稳定型咬合板治疗前后的临床结果以及盘位置、盘活动度、盘形态、关节积液、下颌髁突骨髓水肿模式和退变变化。
治疗后平均最大开口度（MMO）增加，MMO期间的平均疼痛显著减轻。治疗后盘位置、盘活动度和关节积液均有显著改善。
本研究结果表明，关节穿刺和稳定型咬合板治疗在临床结果、盘位置、盘活动度和关节积液方面有显著改善。
