The facial bones. Commonly injured facial bones include the nasal bone (the nose), the maxilla (the bone that forms the upper jaw), and the mandible (the lower jaw). The mandible may be fractured at its symphysis, body, angle, ramus, and condyle. [4] The zygoma (cheekbone) and the frontal bone (forehead) are other sites for fractures. [13]
The first stage is an oedema of the bone marrow initiated by a bone infarct, which is itself modulated by numerous causes, leading to myelofibrosis as a result of hypoxia and gradual loss of bone density characteristic of ischaemic osteoporosis. Further deterioration can be triggered by additional bone infarcts leading to anoxia and localized ...
Those are the bones with the highest prevalence of cysts in the human body, due to the abundant amount of epithelial remnants that can be left in the bones of the jaws. The enamel of teeth is formed from ectoderm (the precursor germ layer to skin and mucosa), and so remnants of epithelium can be left in the bone during odontogenesis (tooth ...
Fractures where large cysts or tumours are in the area (and weaken the jaw), where there is an area of osteomyelitis or where osteonecrosis exist cause special challenges to fixation and healing. Cysts and tumours can limit effective bone to bone contact and osteomyelitis or osteonecrosis compromise blood supply to the bone.
For external use, the clay may be added to the bath, or prepared in wet packs or poultices for application to specific parts of the body. Often, warm packs are prepared; the heat opens up the pores of the skin, and helps the interaction of the clay with the body. [notes 4]
The presence of buccal exostosis can be diagnosed by both clinical examination and radiological interpretation of the oral cavity. Clinically, buccal exostoses appear as single, broad-based masses, usually situated bilaterally in the premolar and molar region on the facial surface of the maxillary alveolar bone. [11]
Finally, the face is "fleshed," meaning clay is added until the tissue thickness markers are covered, and any specific characterization is added (for example, hair, wrinkles in the skin, noted racial traits, glasses, etc.). The skull of Mozart was the basis of his facial reconstruction from anthropological data.
The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [1] The remainder of the skull is the neurocranium. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.
