Objective:
This study compared the clinical outcomes of ultrasound-guided temporomandibular joint lavage and intra-articular injection with traditional methods for treating temporomandibular disorders (TMD), aiming to offer valuable insights for clinical.
Materials And Methods:
Forty TMD patients (20 per group) were randomly assigned to receive either traditional temporomandibular joint lavage and intra-articular injection or an ultrasound-guided approach. Immediate postoperative MRI assessed the joint cavity.
Results:
Ultrasound guidance significantly reduced the number of needle attempts compared to the traditional approach (p < 0.01). Immediate post-procedure MRI showed no significant difference in superior joint cavity injection success between groups. However, the ultrasound-guided group had a significantly better success rate for the inferior joint cavity (p < 0.05). Three days post-procedure, the ultrasound-guided group demonstrated significantly better pain relief and maximum mouth opening (p < 0.05). At seven days post-procedure, there were no significant differences in pain levels or maximum mouth opening between the two groups (p > 0.05). The occurrence of postoperative complications was similar in both groups (p > 0.05).
Conclusion:
Ultrasound-guided treatment is a precise and minimally invasive method for treating TMD, offering better outcomes in terms of pain relief and joint function.
