Treatment Options for Temporomandibular Joint (TMJ) Synovitis

The treatment of TMJ synovitis should follow a stepwise approach, starting with NSAIDs and potentially progressing to DMARDs and biologics for refractory cases, with careful consideration of the patient's skeletal maturity when considering intra-articular injections. 1

Initial Treatment Options

  • NSAIDs (Nonsteroidal Anti-inflammatory Drugs): Conditionally recommended as part of initial therapy for active TMJ synovitis. The trial should be brief due to potential adverse effects (gastritis, bruising) and limited efficacy. 1

  • Intra-articular Glucocorticoid Injections (IAGCs):

    • For skeletally mature patients: May be indicated for active TMJ arthritis with orofacial symptoms. 1
    • For skeletally immature patients: Not recommended as first-line management due to unique TMJ-specific adverse events including heterotopic ossification and impaired growth. Should be used cautiously only in patients with refractory TMJ arthritis and significant symptoms. 1
    • Repeated glucocorticoid injections are not recommended. 1

  • Oral Glucocorticoids: Conditionally recommended against as part of initial therapy for active TMJ arthritis. 1

Second-Line Treatments

  • Conventional Synthetic DMARDs (Disease-Modifying Antirheumatic Drugs): Strongly recommended for inadequate response to or intolerance of NSAIDs and/or IAGCs. 1

    • Methotrexate is conditionally recommended as the preferred agent. 1
    • Leflunomide is recommended as an alternative if methotrexate is not tolerated. 1

  • Biologic DMARDs: Conditionally recommended for inadequate response to or intolerance of NSAIDs and/or IAGCs and at least one conventional synthetic DMARD. 1

    • TNF inhibitors have been most commonly used, though no specific biologic agent is preferred. 1
    • IL-1 inhibitors are restricted to the treatment of systemic JIA. 1

Symptomatic Management

  • Occlusal Splints/Mouthguards: May be beneficial in patients with orofacial symptoms and/or TMJ dysfunction. These are reversible, safe, and relatively low-cost interventions. 1

  • Physical Therapy: May be beneficial for TMJ dysfunction, though evidence is limited and based primarily on extrapolation from related conditions. 1

  • Intra-articular Lavage (without steroids): May be beneficial for TMJ arthritis-related symptoms and dysfunction in both growing and skeletally mature patients. No additional benefit has been reported when steroids are added to the lavage procedure. 1

Management of Dentofacial Deformity

  • Dentofacial Orthopedics and Orthodontics: May improve facial development, occlusion, and function in skeletally immature patients with TMJ arthritis-related dentofacial deformities. 1

  • Skeletal Surgery: May be indicated in both skeletally immature and mature patients with dentofacial deformities and controlled TMJ arthritis. 1

Monitoring and Diagnosis

  • Contrast-enhanced MRI: Currently the best method to detect active TMJ arthritis. 1

  • Clinical Examination: Should be used to diagnose TMJ arthritis-related dysfunction; a standardized approach is recommended to monitor changes over time. 1

Important Considerations and Pitfalls

  • TMJ is considered a high-risk joint due to its major impact on activities of daily living, thus early and aggressive treatment is often warranted. 1

  • Treatment of TMJ arthritis is recommended regardless of the presence of clinical symptoms due to its potentially destructive nature and impact on oral health-related quality of life. 1

  • Intra-articular triamcinolone acetonide with hyaluronic acid injections have shown promise in relieving pain and clicking sounds in TMJ arthritis, though this approach should be used cautiously in skeletally immature patients. 2

  • Complete resolution of synovitis with intra-articular steroid injections occurs in only about 18% of cases, though most patients experience significant reduction in pain and improvement in maximal incisal opening. 3

  • Glucosamine sulfate has shown potential in reducing TMJ pain during function compared to ibuprofen in patients with TMJ osteoarthritis, with a significant carryover effect after discontinuation. 4
