What Are the Mandibular Muscles?
The jaw, pronounced hé g, refers to the bones of the jaw, divided into the maxilla and the mandible.
Jawbone
- maxillary bone
- The bones of the maxilla in the center of the human skull. Pairs, left and right
Jaw Overview
- Jaw osteomyelitis
- A disease caused by infection of the jawbone, which often includes periosteum, bone cortex and bone marrow tissue, clinically common suppurative jaw osteomyelitis, infant osteomyelitis and radiation osteomyelitis.
Jaw alias
- The source of the tooth is pain, swelling of the corresponding part of the face, pus, numbness of the lower lip, obvious redness and swelling in the lower orbit, nasal puncture and pus, fibrous tissue hyperplasia, fibrous tissue swelling, hard fibrous tissue, fistula, pus, and gingival space

Jaw Symptoms
- Jaw osteomyelitis: (a) acute jaw osteomyelitis
- The onset was sharp and systemic symptoms were obvious. Locally predisposed source tooth pain, which quickly spreads to adjacent teeth, causing pain throughout the affected side and spreading to the temporal area. The corresponding part of the face is swollen, the gums and vestibular sulcus are red and swollen, and many teeth in the affected area are loose. Pus often overflows from the periodontal area. Mandibular osteomyelitis, due to masticatory muscle invasion, often has varying degrees of mouth opening limitation. When the inferior alveolar nerve is involved, there may be numbness of the affected lower lip. Maxillary osteomyelitis is more common in newborns and infants, and the source of infection is often blood-borne. Its local manifestations are marked redness and swelling in the lower orbit, which often extends to the periphery of the eyes and can't open the eyes. In the later period, the pus can be punctured through the internal condyles, nasal cavity and oral cavity.
- (Two) chronic jaw osteomyelitis
- Acute jaw osteomyelitis can become chronic if it is not completely treated. A common cause is purely conservative treatment with drugs, pus pierce itself, and poor drainage. During chronic jaw osteomyelitis, most of the acute symptoms subsided, systemic symptoms were not obvious, and pain was significantly reduced. Local fibrous tissue hyperplasia, swelling and stiffness. Fistula, often overflowing pus, even discharge small pieces of dead bone. Multiple teeth were loosened in the lesion area, and the gingival space was purulent. When the body's resistance is reduced or drainage is not smooth, it can be acute. Delays can cause weight loss, anemia, and physical weakness.
Jaw Pathology
- There are three main sources of infection of jaw osteomyelitis, namely dental, trauma and blood.
- Hematogenous jaw osteomyelitis is rare and occurs mainly in children. Dentogenic jaw osteomyelitis is the most common, accounting for about 90% of all jaw osteomyelitis. Due to the improvement of medical conditions in China, the incidence has dropped significantly. Dentogenic jaw osteomyelitis is more common, which is related to factors such as dense mandible cortical bone, hypertrophy muscles and dense fascia attachment, and accumulation of pus in the medullary cavity.
Jaw Treatment
- The timely treatment of odontogenic infections such as pericyta and periapical inflammation has positive significance for preventing the occurrence of jaw osteomyelitis. If osteomyelitis has developed, it should be thoroughly treated during the acute phase to avoid becoming chronic.
- The systemic treatment of acute jaw osteomyelitis is the same as that of perianal cellulitis, mainly to enhance the body's resistance and drugs to control the infection (metronidazole, spiramycin). Local treatment focuses on timely incision and drainage to remove the source tooth.
- In chronic jaw osteomyelitis, efforts should be made to improve the condition of the patient's body, maintain smooth drainage, timely extraction of diseased teeth, thorough removal of lesions, curettage or removal of dead bone.
