Septic Arthritis in the Temporomandibular Joint.

Area of Science:

• Infectious Diseases
• Orthopedic Surgery
• Radiology

Background:

• Septic arthritis of the temporomandibular joint (TMJ) is an uncommon condition with limited reported cases globally.
• This report details a unique instance of TMJ septic arthritis in a previously healthy young adult male.

Observation:

• The patient presented with periauricular swelling, erythema, fever, myalgia, and generalized joint pain.
• Initial computed tomography (CT) was inconclusive for joint effusion, but subsequent magnetic resonance imaging (MRI) confirmed TMJ effusion.
• Cultures of the drained synovial fluid identified methicillin-sensitive Staphylococcus Aureus.

Findings:

• The case underscores the specific clinical presentation of septic arthritis affecting the temporomandibular joint.
• Diagnostic imaging revealed the utility of MRI in detecting TMJ effusions, especially when CT scans yield negative results.

Implications:

• Early and accurate diagnosis of TMJ septic arthritis is critical for effective management and patient outcomes.
• MRI should be considered a valuable tool in the diagnostic workup for suspected TMJ effusions, complementing CT findings.
