Septic arthritis of the temporomandibular joint in adults: Systematic review.

BACKGROUND

Septic arthritis of the temporomandibular joint (SATMJ) is acute or chronic bacterial or fungal infection involving temporomandibular joint (TMJ) space. It is a disease with high mortality in whole body joints, and about three-fourths of survivors have residual malfunctioning of the affected joint.

OBJECTIVE

The aim of this review was to search systematically, evaluate and then summarize scientific literature about etiology, signs and symptoms, diagnosis, treatment and prognosis of the SATMJ in adults.

METHODS

After registration at PROSPERO this systematic review was conducted and reported according to the PRISMA checklist. The following databases were systematically searched: MEDLINE, EBSCO, The Cochrane Central Register of Controlled Trials (Central), SCIndex, Scopus, Google Scholar and Registry of clinical studies with human participants.

RESULTS

In total 37 studies with 91 patients were included in the review. Dominant signs and symptoms of SATMJ were pain and trismus, while fever was infrequent. The most frequent isolates from the TMJ were Staphylococcus aureus and Streptococci; however, less than 20% of patients had data about susceptibility of the isolates to antibiotics. Combination of third generation cephalosporin and metronidazole was the most frequently prescribed empirically, and antibiotics especially active against S. aureus (glycopeptides and anti-staphylococcal beta-lactams) were under-prescribed. Administration of antibiotics was prolonged (median over 30 days), although two weeks are sufficient treatment for SATMJ if right choice of antibiotics was made. There was high rate of repeated surgical interventions (53.5%), which were linked to higher risk of long-term functional defects.

CONCLUSIONS

The SATMJ is serious infection that requires early empiric administration of antibiotics with good coverage of Gram-positive bacteria, and subsequent correction of antibiotic therapy according to susceptibility of isolates. Appropriate antibiotic therapy decreases risk of long-term functional disorders.
