Key Points

The study aims to evaluate the effectiveness of ultrasound guidance in arthrocentesis with platelet-rich plasma (PRP) for treating TMJ internal derangements.
Conducted as a randomized controlled trial
Participants underwent arthrocentesis with or without ultrasound guidance
PRP was used in both procedures to assess its impact
Clinical and radiological outcomes were measured at 3 months post-procedure
Patients receiving ultrasound guidance experienced faster early recovery
Both ultrasound and non-ultrasound methods had similar clinical outcomes at 3 months
Radiological outcomes did not significantly differ between the two methods

Answers are grounded in this paper and cite their sources.

US guidance enabled faster early recovery, but both methods showed comparable clinical and radiological outcomes at 3 months.
