Patients with osteomyelitis of the jaw generally favor conservative treatment as well as adjunctive therapies: i. Antibiotics are used during the onset of the disease to prevent systemic infections, and care is taken to keep the mouth clean and eliminate all possibility of infection in the mouth. ii. After the necrotic jawbone is separated from the new jawbone, surgical resection is performed. Therefore, the disease is longer and more serious. Secondly, the necrotic jawbone can also be removed by removing the nearby tissues together, but this method of treatment is more risky. Third, the current treatment method also includes hyperbaric oxygen combined with surgical treatment, which can promote the separation of necrotic jawbone and enhance the repair function of new bone. In addition, it also has the effect of sterilizing and preventing infection. In addition, due to the long treatment period of osteomyelitis of the jaw, the disease is mainly focused on preventing morbidity. When radiotherapy is given for malignant tumors of the facial region, care should be taken to isolate areas that do not require radiotherapy.
