Osteomyelitis of jaws - infectious inflammatory process at which elements of a gnathic bone are amazed all. Distinguish an osteomyelitis hematogenic, traumatic and dontogenous (the most widespread version). An etiology of a dontogenous osteomyelitis - a microflora of root channels of a teeth and dental gingival pockets (streptococcuses, staphilococcuses).

The pathogenesis is bound to diffusion of inflammatory process on an osteal tissue. Contagiums get from a periodontium on lymphatic vessels and osteal canaliculuses. The role of a previous microbial sensibilization of an organism is important.

Signs, current. At an acute osteomyelitis: a spontaneous throbbing pain in a jaw, a headache, a cold fit, temperature up to 40 degrees. The amazed tooth with a pulp (probably with a seal) is found out; it and a teeth adjoining them are sharply morbid, mobile. The hydropic azygomorphous face. The transitive cord reddened also is smoothed. Lymph nodes are enlarged, morbid. The osteomyelitis quite often becomes complicated an abscess, a phlegmon. In a blood a leukocytosis, an ESR it is enlarged.

The forecast depends on well-timed active treatment and a condition refractory ™ an organism. Quite often process accepts chronic current. Signs of a chronic osteomyelitis - fistulas with purulent separated and granulations on a mucosa of an alveolar process and a skin of the face and a neck, a teeth are mobile and morbid, asymmetry of the face. Current long - months, years; frequent exacerbations. The osteomyelitis of the top jaw can become complicated a genyantritis, a thrombophlebitis of facial veins. Pathological fracture of a mandible is possible.
