Study Notes
- Osteomyelitis is an infectious inflammatory disease of bone caused by bacterial colonization of the bone marrow.
- It is more common in the mandible due to poor blood supply and dense cortical bone.
- Etiology includes malnutrition, alcoholism, diabetes, leukemia, anemia, irradiated bone, drugs, and other bone diseases.
- Odontogenic infections are the most common cause, but facial trauma and radiotherapy can also lead to osteomyelitis.
- Acute forms present with pain, inflammation, exposed bone, cheek swelling, discharge/drainage, and paresthesia of the alveolar nerve.
- Chronic forms can appear as primary or secondary to an acute form, with spontaneous pain and a long discharge of pus.
- Management includes antibiotic treatment, surgical drainage of pus, and surgical debridement (sequestrectomy) for chronic phases.
- Local vascularization must be improved for good healing.
- Medication-related osteonecrosis of the jaws (MROJ) can also lead to osteomyelitis.
- Other bone diseases like Paget's disease and florid osseous dysplasia can increase susceptibility to osteomyelitis.
