An Advanced Case of TMJ Osteoarthritis

Advanced temporomandibular joint (TMJ) osteoarthritis can present with several complications, including synovial cyst formation. Through this work , we present a case of a 69-year-old patient with bilateral painful swelling in the parotid regions, he previously operated for goiter in 2003 without any complications. Magnetic resonance imaging (MRI) revealed bilateral temporomandibular joint effusion with a cystic formation on the left, extending from the posterior border of the masseter muscle to the anterior margin of the superficial lobe of the parotid gland, communicating with the joint space. Additionally, there were findings of TMJ irregularities, condylar degeneration, and contrast-enhancing synovial thickening indicative of osteoarthritis. Computed tomography (CT) complement highlighted bilateral condylar flattening with joint space narrowing and osteoarthritic changes
