Ultrasound-guided Versus Arthroscopic Guided PRF Injection for TMJ Disc Displacement.
Sponsor: Cairo University
Summary
To compare the clinical effectiveness of ultrasound-guided versus arthroscopic guided platelet rich fibrin injection in the management of anterior disc displacement with reduction of the temporomandibular joint, in terms of pain reduction, improvement of mandibular function, and patient-reported outcomes.

Conditions
Interventions
ultrasound guided platelet rich fibrin injection
1. A high-frequency linear ultrasound probe will be used to identify the TMJ space. 2. A sterile syringe containing 1 mL of PRF will be inserted into the superior joint space under real-time ultrasound guidance. 3. PRF will be injected slowly with continuous confirmation of needle position.
Arthroscopic guided platelet rich Fibrin injection
1. TMJ arthroscopy will be performed under local or general anesthesia following standard aseptic preparation. 2. The superior joint space will be visualized using a 1.9 mm arthroscope. 3. A sterile syringe containing 1 mL of PRF will be introduced through a lateral portal under direct arthroscopic visualization. 4. PRF will be injected slowly into the superior joint space.
