[Septic arthritis of the temporomandibular joint: report of one case]

Area of Science:

• Otorhinolaryngology
• Infectious Diseases
• Rheumatology

Background:

• Septic arthritis of the temporomandibular joint (TMJ) is uncommon.
• It can arise from hematogenous bacterial spread or contiguous infections in the head and neck.
• Otitis and mastoiditis are potential sources of contiguous spread.

Observation:

• A 41-year-old female presented with right TMJ involvement.
• Imaging revealed mandibular condyle bone destruction and spread to the temporal space.
• The infection followed necrotizing medial and external otitis with mastoiditis.

Findings:

• Diagnosis of septic arthritis of the TMJ by continuity was established.
• Treatment included antimicrobials, TMJ arthrocentesis, and occlusal stabilization.
• The patient showed positive initial response to treatment.

Implications:

• Septic TMJ arthritis can lead to secondary temporomandibular joint osteoarthritis.
• Prompt diagnosis and treatment are crucial to prevent long-term joint damage.
• This case underscores the importance of considering TMJ involvement in severe head and neck infections.
