The Effect of Ultrasound guided versus conventional arthrocentesis in treatment of temporomandibular joint internal derangement: A comparative study.

Abstract

Objectives: The objective of this research was to evaluate the impact of Ultrasound-guided arthrocentesis compared to conventional arthrocentesis in managing internal derangement of the temporomandibular joint.Materials and Methods: Our study involved 16 female individuals diagnosed with internal derangement of the temporomandibular joint, specifically anterior disk displacement with or without reduction. These participants were divided into two cohorts: a control group treated with conventional arthrocentesis and a test group administered ultrasound-guided arthrocentesis. Both groups received hyaluronic acid injection via a single needle double barrel cannula and underwent postoperative low-level laser therapy as supplementary therapy. The primary outcome assessed was the maximum mouth opening. Follow-up assessments were conducted at intervals of 2, 4-, 6-, 8-, and 12-weeks post-surgery.Results: There were no notable variances observed between the two groups concerning the specified outcome. Nonetheless, both methods proved effective in enhancing mouth opening compared to measurements taken prior to the operation.Conclusion: This research reinforces the efficacy of both ultrasound-guided and conventional arthrocentesis in addressing TMJ internal derangement. Nonetheless, additional investigation is necessary to elucidate the contribution of ultrasound to enhancing treatment results for TMJ disorders.
