Osteomyelitis

  1. 1. By : kanwal fateema soomro
  2. 2. Introduction Explanation Classification Research article
  3. 3. Osteomyelitis = derived from Greek words; Osteon = bone Myelo = marrow It is = inflammation
  4. 4. It’s the inflammation of bone and its medullary part usually results as a complication of dental sepsis
  5. 5. Streptococcus Aureus Staphylococcus Albus Prophyromonas Prevotella. Anaerobes: bacteroids, prevotella, prophyromonas.
  6. 6. Local factors: trauma due to gunshots, wounds, radiations. Systemic conditions : malnutrition, sickle cell anemia, alcoholism(NB), leukemia, DM
  7. 7. Suppurative : 1. Acute 2. chronic Primary (non preceding phase) Secondary (follow an acute phase)
  8. 8. Non suppurative 1. Diffuse sclerosing OM 2. Focal sclerosing OM (condensing osteitis) 3. Proliferative periostitis (Garre’s sclerosing OM) 4. Osteoradionecrois
  9. 9.  Clinical features: 1. In both maxilla and mandible but remain localize in maxilla 2. Not so common in era of antibiotics. 3. all inflammatory signs .
  10. 10. 1. Paresthesia of lip. 2. Teeth involved are sore and dysphagia.
  11. 11.  Disease cant be diagnosed until 10 to 15 days.  Bone tuberculae become fuzzy and indistinct…  After that begin to appear radiolucent areas…
  12. 12.  As its acute so there are chiefly PMNLs.  Bone tuberculae undergo resorption.
  13. 13.  Rarely occur due to complication of irradiation.  All signs are same like in acute but little milder .  Acute exacerbations may occur any time.  Suppuration may perforate through bone forming a fistula.
  14. 14.  Also called condensing osteomyelitis.  Usually reaction of bone to any infection.  Through carious tooth  Tissue react as by proliferation rather destruction, as infection acts as stimulus rather than irritant.
  15. 15.  In young adults and children.  Mostly affected are mandibular 1st molar.  No such signs and symptoms just mild pain with infected pulp.
  16. 16.  Well circumscribed radiopaque mass of sclerotic bone.  Lamina dura intact  Periodontal space widened (NB feature).
  17. 17.  Dense mass of bony tuberculae with little marrow.  Osteocytes appear empty.  Lines gives pagetoid appearance.  Fibrotic soft tissue if present.
  18. 18.  This is from the diffuse periodontal disease.
  19. 19.  In older patients  Mostly in edentulous mandible areas  vague pain  Unpleasant taste with mild suppuration.  Usually pain is subside due to drainage of suppuration through the fistula formation in mucosa.
  20. 20.  Diffuse patchy,  cotton-wool appearance in sclerosis of bone.  Indistinct often  Usually mimic the diseases ; Paget's disease, cemento-osseous dysplasia.
  21. 21.  Active osteoclasts.  Mosaic pattern  Soft tissue fibrous in trabeculae of bone.  PMNLs and chronic inflammatory cells
  22. 22.  Also called Garre’s syndrome, periostitis ossificans.  Types of chronic OM in which focal gross thickening of periosteum.  Reactive bone formation resulting from mild irritation or infection.
  23. 23.  In young individuals often < 25 years.  In mandible.  Often results from cellulitis or any soft tissue infection.  Odontalgia, and pain in jaw.  Bony hard swelling on outer surface of jaw.
  24. 24.  Occlusal radiograph shows the focal overgrowth of the bone.  The mass is smooth and rather well calcified, which may show thin cortical layer of its own.
  25. 25.  Osteoblasts bordering the tuberculae in a retiform pattern.  C.T between is fibrous which may show diffuse patchy sprinkling of lymphocytes and plasma cells.  In periosteal reaction; carious tooth causes perforation of cortical plate.
  26. 26. DONE by parsad and kishore and co-workers. PURPOSE: To analyze the behavior to osteomyelitis in head and neck and its management. 84 cases in 10 years
  27. 27. RESULTS: 1.Mandible (most common) 2.Frontal bone 3.Cervicle spine. 4. Maxilla. 9%patients----- acute osteomyelitis. 75% patients----- chronic osteomyelitis.
  28. 28. CAUSES: 1. Chr. Sinusitis: 100% 2. T.B : 67% 3. Radiation induced ORN : 41% 4. Malignancy: 33% 5. Odontogenic infection: 30%
