Outcomes of modified arthrocentesis using concentric needle and cannula technique with sequential viscosupplementation and orthobiologics in both TMJ compartments.

Minimally invasive therapeutic procedures have been applied for the management of degenerative joint disease in the temporomandibular joint (TMJ). This study describes a modified technique of arthrocentesis with concentric needle and cannula in the TMJ associated with viscosupplementation and/or orthobiologics. Its effects were evaluated based on clinical outcomes related to pain, mouth opening, and joint sound, along with longitudinal tomographic evaluation based on the Wilkes classification.
