Background and Aim. Irrecoverable anterior disc displacement (ADD) of temporomandibular joint (TMJ) seriously affects the quality of life of patients. This research was aimed to explore the recovery effect of small incision reduction and suture on patients. Methods. 90 patients with irreducible ADD of TMJ treated from August 2020 to August 2021 were acquired in our hospital. They were randomly divided into control group and trial group randomly. There were 45 patients in each group. The sufferers in the control group were treated with oral drug therapy and small incision reduction and suture, while those in the trial group were treated with small incision reduction and suture linked with functional appliance. The pain score, dysfunction, joint function recovery, facial improvement, and clinical impacts of the two groups were contrasted. Results. Compared with that in the control group at 1 week, 4 weeks, and 6 months after therapy, the pain score in the trial group was markedly higher. After therapy, in the two groups, maximum vertical opening (MVO), left lateral excursion (LLE), and right lateral excursion (RLE) levels were markedly higher than those in the control group. The MRI score of the trial group was markedly higher than that of the control group at 1 week, 4 weeks, and 6 months after therapy, and the total effective rate of the trial group was markedly higher than that of the control group. Conclusion. The use of small incision reduction and suture linked with functional appliance in the therapy of sufferers with irreducible ADD of TMJ is beneficial to relieve pain, promote the recovery of body function, and contribute to the recovery of joint function.

小切口复位缝合对不可恢复的颞下颌关节前盘移位患者功能矫治的影响


背景和目标。不可恢复的颞下颌关节（TMJ）椎间盘前移（ADD）严重影响患者的生活质量。本研究旨在探讨小切口复位缝合对患者的康复效果。方法。收集2020年8月至2021年8月我院收治的90例不可复性TMJADD患者。将他们随机分为对照组和试验组。每组各有45名患者。对照组采用口服药物治疗及小切口复位缝合治疗，试验组采用小切口复位缝合联合功能矫治器治疗。比较两组的疼痛评分、功能障碍、关节功能恢复、面部改善和临床影响。结果。治疗后1周、4周、6个月时，试验组疼痛评分明显高于对照组。治疗后，两组的最大垂直张开（MVO）、左侧偏移（LLE）和右侧偏移（RLE）水平均显着高于对照组。治疗后1周、4周、6个月试验组MRI评分显着高于对照组，试验组总有效率显着高于对照组。结论。采用小切口复位缝合联合功能矫治器治疗不可复性TMJADD患者，有利于缓解疼痛，促进机体功能恢复，有助于关节功能的恢复。
