Osteomyelitis of the mandible

Area of Science:

• Oral and Maxillofacial Surgery
• Infectious Diseases
• Oncology

Background:

• Mandibular bone infections, including posttraumatic osteomyelitis, odontogenic osteomyelitis, and osteoradionecrosis, present complex clinical challenges.
• These infections are frequently polymicrobial, with a significant role for anaerobic bacteria.
• Understanding the distinct characteristics and treatment responses is crucial for effective management.

Purpose of the Study:

• To describe the presenting characteristics and clinical courses of patients with mandibular bone infections.
• To evaluate the impact of surgical procedures and hyperbaric oxygen therapy.
• To propose and validate a clinical staging system for guiding treatment decisions.

Main Methods:

• Retrospective analysis of 60 patients with mandibular bone infections.
• Categorization of infections into posttraumatic osteomyelitis, odontogenic osteomyelitis, and osteoradionecrosis.
• Evaluation of treatment outcomes based on a proposed clinical staging system.

Main Results:

• Most infections (93%) were polymicrobial, with anaerobes being significant pathogens.
• Minimal differences observed in presentation or treatment response across infection types.
• Treatment outcomes showed a positive correlation with the proposed clinical staging system.

Conclusions:

• A novel clinical staging system for mandibular bone infections can guide treatment planning.
• Initial treatment planning based on disease stage is safe and effective.
• Further research into tailored therapeutic strategies for different stages is warranted.
