A Case of Chronic Infectious Arthritis of the Temporomandibular Joint Associated with Osteomyelitis without Malocclusion

Severe septic arthritis of the temporomandibular joint with pyogenic orofacial infections: A case report and review of the literature

Septic arthritis of the temporomandibular joint (SATMJ) is a rare entity that has only been reported a few dozen times worldwide. However, SATMJ is an acute infectious disease and associated with a high risk for misdiagnosis, which results in severe complications for patients. The present study reported a case of an 83-year-old female patient with severe pyogenic orofacial infections caused by right-side SATMJ, which was not cured by abscess incision drainage and anti-microbial treatment. Finally, the clinical signs were resolved by condylectomy and debridement of the erosive septic TMJ, after which the function of the TMJ was completely restored. In conclusion, a timely and correct diagnosis with early treatment is critical to preventing acute complications and late sequelae of SATMJ. In addition, literature associated with this topic was reviewed and discussed.

Bilateral septic arthritis of the temporo mandibular joint: case report

Septic arthritis of the temporo-mandibular joint (TMJ) is a rare disease that has been reported infrequently. To the best of the authors' knowledge, only one case of bilateral TMJ septic arthritis has been reported. The contamination may result from direct extension of adjacent infection (dental or ENT), from hematogenous spread of blood-borne organisms or from direct inoculation. The most common presenting are trismus and pain, although swelling, tenderness and erythema have also been described. In addition, patients may develop fever, regional lymphadenopathy and malocclusion. Through a successively bilateral case of TMJ arthritis, without obvious portal of entry of the bacteria, we will analyze characteristics and treatment of this disease.

Septic Arthritis of the Temporomandibular Joint--Unusual Presentations

This report describes 2 patients whose septic arthritis of the temporomandibular joint (SATMJ) presented atypically, resulting in treatment delay and complications. A 49-year-old man developed left-side facial allodynia, which was first treated unsuccessfully as trigeminal neuralgia. On day 21, the patient sustained facial trauma from a fall and presented to the emergency department (ED). Maxillofacial contrast-enhanced computed tomographic (CT) scan was suggestive of parotiditis, SATMJ, or hemarthrosis. His condition did not improve with empiric antibiotic treatment. On day 30, contrast-enhanced magnetic resonance imaging (MRI) confirmed SATMJ. Incision and drainage yielded 6 mL of pus and produced clinical improvement. Cultures grew methicillin-resistant Staphylococcus aureus, which was treated with amoxicillin plus clavulanate and sulfamethoxazole plus trimethoprim for 30 days. On day 59, the patient still had slight preauricular pain and CT-proved TMJ osteoarthritic changes. A 56-year-old woman developed right-side facial pain after a crown procedure on her right mandibular second molar. Oral prednisone (and clindamycin) produced partial relief. Her primary physician suspected temporal arteritis, but its biopsy result on day 11 was normal. Gradually, the patient developed trismus and malocclusion refractory to various medicines. On day 49, she presented to the ED. A contrast-enhanced maxillofacial CT scan suggested SATMJ. Incision and drainage yielded 30 mL of pus and produced clinical improvement. During days 50 to 57, the patient received intravenous ampicillin plus sulbactam and metronidazole. However, preauricular tenderness and drainage from the surgical incision persisted. On day 55, CT scan showed a residual abscess. Secondary debridement yielded 5 mL of pus. Culture grew coagulase-negative S aureus. On day 141, the patient still had slight preauricular pain and TMJ osteoarthritic changes on MRI. In these cases, the SATMJ diagnosis was delayed owing to the mildness of local and systemic manifestations, the possibility of confounding conditions, and the rarity of SATMJ. Contrast-enhanced CT and MRI facilitated the diagnosis. Abscess drainage alleviated the symptoms. Postinfectious osteoarthritis developed possibly from treatment delay. SATMJ should be considered in all patients with enigmatic preauricular pain, trismus, or malocclusion.
