目的:评价粘弹补充治疗TMJ不可复性关节盘前移位的临床效果。方法:用透明质酸纳对43例不可复性关节盘前移位患者行TMJ上腔粘弹补充治疗术,在治疗的同时配合被动张口训练。治疗后随访记录患者疼痛、张口度等相关情况。将TMJ上腔粘弹补充治疗术前、术后不同时期的疼痛指数、下颌侧向运动度、最大开口度进行统计分析。结果:治疗后不同时期的下颌运动度均较治疗前有显著增加(P<0.05),特别在治疗后1个月内增加明显,疼痛亦有显著缓解(P<0.05)。结论:TMJ上腔粘弹补充治疗术能改善不可复关节盘前移位患者的张口度,能有效地减缓疼痛,有效改善下颌健侧侧向运动度,粘弹补充治疗术疗效确切,副作用少,是一种安全、有效的治疗方法,具有较好的临床应用推广价值。
OBJECTIVE: To evaluate the clinical effect of viscoelastic replenishment in the treatment of TMJ irreversible joint anterior disc displacement. Methods: Forty - three patients with unrefoverable anterior disc displacement were treated with TMJ superior cavity viscoelastic replenishment with hyaluronic acid sodium. At the same time, they were treated with passive mouth opening. Follow-up after treatment recorded patients with pain, mouth and other related circumstances. The pain index, the degree of lateral movement of the mandible and the maximum degree of opening of TMJ superior cavity viscoelastic treatment were statistically analyzed before and after surgery. Results: The degrees of mandibular movement in different periods after treatment were significantly increased (P <0.05), especially in 1 month after treatment. The pain relief was significantly relieved (P <0.05). CONCLUSION: TMJ superior cavity viscoelastic supplementation can improve the mouth opening of patients with irrecoverable anterior disk dislocation, relieve the pain effectively and effectively improve the side-to-side lateral mandibular movement. The viscoelastic supplement is effective and has few side effects , Is a safe and effective treatment, with good clinical application of promotional value.
