Summary
A comparative evaluation study of arthroscopic retrodiscal tissue injection versus ultrasound-guided injection in temporomandibular joint disorders aims to assess differences in pain relief, functional improvement, and clinical outcomes between an invasive and a minimally invasive delivery technique. Arthroscopic injection allows direct visualization of intra-articular structures, accurate targeting of the retrodiscal tissues, and simultaneous management of associated pathology such as synovitis or adhesions, which may enhance therapeutic outcomes in advanced internal derangement. In contrast, ultrasound-guided injection offers a less invasive, cost-effective, and outpatient-based approach with improved accuracy over blind techniques, making it suitable for early or moderate cases. While both methods are effective in reducing pain and improving mouth opening and jaw function, arthroscopic injection may provide superior results in patients requiring diagnostic confirmation and mechanical intervention, whereas ultrasound-guided injection offers comparable symptomatic improvement with lower procedural morbidity and resource utilization.
