Abstract

Objective: This study aimed to evaluate the clinical efficacy of using ultrasound guidance during intra-articular injection of hyaluronic acid (HA) in the management of patients with TMJ internal derangement. Material/subjects and Methods: Forty patients complaining of anterior disc displacement with reduction (DDwR) not responsive to conservative treatment were enrolled in this study. The diagnosis was based on the current update of diagnostic criteria for temporomandibular disorders (TMDs). Intra-articular injection of Hyaluronic Acid guided by Ultrasound in the first group and Intra-articular Injection (IAI) of HA conventional way in the second group were performed. Articular pain was evaluated using the visual analog scale (VAS). The measured parameters were assessed preoperatively, one week, three month, and six months postoperatively. Data were statistically analyzed (α=0.05). Results: Ultrasound-guided HA injections for the TMJ provide faster pain relief compared to the conventional technique. This method may represent a clinically advantageous approach for optimizing patient outcomes and improving joint function Conclusions: The results of this trial substantiate the integration of ultrasound guidance as a useful adjunct / promising technique for intra-articular TMJ injections. It elevates the procedure from landmark-dependent technique to a targeted and evidence-based intervention. The demonstrated benefits of accelerated pain relief outcomes can significantly enhance patient satisfaction, reduce overall morbidity.
