Masticator space abscesses have been reported more frequently in recent years. They are usually secondary to extractions of the first and second mandibular molar teeth. The use of antibiotics has changed the presentation and clinical course of these abscesses, masking the symptoms and resulting in secondary infection by resistant organisms. Therefore, selection of appropriate antibiotics is important, but surgical intervention remains the cornerstone of treatment. Suspension wires are being used widely in the treatment of midface fractures. These wires may extend from the zygomatic arch or frontal bone through the masticator space into the oral cavity to attach to arch bars. A case of masticator space abscess resulting from the removal of suspension wires is reported, and the relevant literature is reviewed. Suggestions are made for preventing and treating this complication.
