| Objective: To explore the clinical efficacy of ultrasound-guided manual reduction and traditional manual reduction in treating temporomandibular disorders (TMD). Methods: A total of 80 TMD patients admitted to our hospital were selected and randomly divided into control group and observation group, with 40 patients in each group. The patients in the control group were treated with traditional manipulative repositioning, and the observation group was treated with ultrasound-guided manipulative repositioning. The maximal opening degree, pain degree, imaging indexes, improvement of joint popping and clinical efficacy were compared between the 2 groups. Results: After treatment, the maximum mouth opening degree of patients in both groups increased as compared with that before treatment (P<0.01), and the maximum mouth opening degree, total improvement rate, and clinical efficacy rate in the observation group were higher than those in the control group (P<0.05，0.01). The visual analogue score (VAS) of pain, the disc-surface pinch angle of the open-mouth and closed-mouth positions of the patients in the two groups were lower than before treatment (P<0.01), and the VAS score, the open-mouth position, and the closed-mouth position disc-surface pinch angle in the observation group were lower than those in the control group (P<0.05，0.01). Conclusion: Ultrasound-guided manual reduction can effectively improve the maximum opening degree of TMD patients, reduce pain, improve joint elasticity and imaging indicators, and enhance clinical efficacy compared to traditional manual reduction. |
