Septic Arthritis of the Temporomandibular Joint: A Systematic Review

The purpose of this study was to describe the characteristics of the patient history, clinical findings, laboratory tests, treatment, and long-term function of septic arthritis of the temporomandibular joint (SATMJ).

All articles in the English literature related to SATMJ were queried using PubMed, Embase, and the Cochrane Library (1950 to July 1, 2020). The reference lists were reviewed for additional articles.

A preliminary search of the literature returned 241 results, of which 37 met inclusion criteria, with an additional article from reference review. There were 93 total cases, with a mean age of 35.7 years (0.1 to 85). Symptoms mostly consisted of pain in the temporomandibular joint/preauricular region (n = 84, 90.3%), trismus (n = 73, 78.5%), and facial/preauricular swelling (n = 68, 73.1%). Most patients had no systemic symptoms (n = 80, 86.1%). The mean degree of mouth opening was 13.1 mm (5 to 35). Diagnosis was made with the following imaging modalities: radiograph (n = 48, 51.6%), CT scan (n = 35, 37.6%), MRI (n = 25, 26.9%), and ultrasound (n = 3, 3.2%). Staphylococcus aureus (n = 19, 20.4%) was most commonly isolated. About 92 patients (98.9%) received antibiotics and 85 patients underwent surgery (eg, arthrocentesis, arthroscopy, etc.), of which 15 patients (17.6%) required repeat surgery. Most long-term outcomes were favorable. Sequelae occurred in 26 of 85 patients (30.6%) with documented follow-up.

SATMJ should be suspected in the presence of trismus, jaw pain, and preauricular swelling. Management includes prompt evaluation and treatment with broad-spectrum antibiotics. Surgery is not always indicated but can be life-saving in severe cases.
