  2. 2. What is the Temporomandibular Joint?The temporomandibular joint (TMJ) is a typicalsliding "ball and socket" which has a discsandwiched between it. The TMJ is used manythousands of times a day in moving the jaw,biting and chewing, talking, yawning, etc. It isone of the most frequently used of all the jointsin the body.http://www.medicinenet.com/temporomandibular_joint__disorder/page1.htm#1whatis

  59. 59. Questions that Arise:• Since bilateral enhancement is so common, could it be a normal post-contrast finding?• Could condylar flattening by itself, or with enhancement, be a normal finding?• If the above is true: 50% of the kids currently found to have abnormal TMJs by MRI could be normal.• Therefore: Important to have controls, especially to help make treatment decisions.

  68. 68. What do we do for TMJ arthritisnot responsive to IA-steroids?• Many have already failed repeated (2 or more) IA-steroid injections.• The vast majority are already on high dose, aggressive systemic arthritis therapy (e.g. methotrexate and anti-TNF agents at high doses).

TMJ symptoms improved after the first bilateral intra-articular infliximab injections but even more so after the second injections. The considerable improvement remained for the 36 weeks studied. Bilateral computerized tomography showed no progression in radiographic changes during the treatment. No adverse reaction was observed from the intra-articular injections.

  71. 71. Do non-JIA children with otherrheumatic diseases develop TMJ arthritis?• Many other pediatric rheumatic disorders are associated with arthritis (SLE, myositis, sarcoidosis, Sjogren, MCTD, etc.).• Some children with the above disorders have PE findings or complaints suggestive of TMJ arthritis.

  77. 77. Things to Consider• 50-75% of children with JIA develop TMJ arthritis.• All subtypes of JIA develop TMJ arthritis.• TMJ arthritis is frequently asymptomatic.• Inflammation of the TMJ leads to growth plate arrest (micrognathia).• MRI is the most sensitive modality for detecting TMJ arthritis.• Intraarticular corticosteroid injection is effective treatment for TMJ arthritis in JIA.• TMJ arthritis can develop while being treated with methotrexate plus a TNF inhibitor.• TMJ arthritis may be active while other joints are in remission.• Intraarticular infliximab injection treats refractory TMJ arthritis.• Children with sarcoidosis, Sjogren, JDMS, and MCTD can develop destructive TMJ arthritis.
