A35: Differential Benefit of Temporomandibular Joint Steroid Injections by Juvenile Idiopathic Arthritis Subtype

20–70% of juvenile idiopathic arthritis (JIA) patients have radiographic involvement of temporomandibular joints (TMJs), often reflective of cartilage loss and erosive bony changes. Intra‐articular steroid (IAS) injections have been shown by magnetic resonance (MR) imaging to reduce TMJ inflammation; however, it is less clear that this therapy provides longer term benefit in terms of preventing or retarding structural changes. Herein, we review the outcomes of our JIA patients treated with IAS for TMJ synovitis.
