Osteomyelitis of the Jaws

Dr. Ramank Mathur

The word “osteomyelitis” originates from the

ancient Greek words osteon (bone) and

muelinos (marrow) and means infection of

medullary portion of the bone.

The infection- pus and edema in the

medullary cavity and beneath the periosteum

compromises or obstructs the local blood

supply.

Following ischemia, the infected bone

becomes necrotic and leads to sequester

formation, which is considered a classical

sign of osteomyelitis (Topazian 1994, 2002).

True infection of the bone induced by

pyogenic microorganisms (Marx1991).

In the preantibiotic era:

an acute onset secondary chronic

process (Wassmund 1935; Axhausen 1934).

After the introduction of antibiotics:

Subacute or chronic forms of osteomyelitis

(Becker 1973; Bünger 1984).

Suppurative osteomyelitis(acute & chronic)

Chronic sclerosing non-suppurative

osteomyelitis or Garre’s osteomyelitis

Osteomyelitis accompanying systemic disease

such as tuberculosis,actinomycosis & syphillis

2. Sinusitis

3. Vascular insufficiency

C. Hematogenous(metastatic)

1. Developing skeleton (children)

II. Chronic forms of osteomyelitis

Classification based on clinical

picture and

radiology.

The two major groups (acute and

chronic osteomyelitis) are

differentiated

by the clinical course of the

disease after onset, relative to

surgical

and antimicrobial therapy. The

arbitrary time limit of 1 month is

used

to differentiate acute from chronic

osteomyelitis (Marx 1991;

Mercuri1991;

Koorbusch1992).

C. Suppurative or nonsuppurative

1. Inadequately treated forms

2. Systemically compromised

forms

3. Refractory forms (chronic

recurrent

multifocal osteomyelitis

CROM)

D. Diffuse sclerosing

1. Fastidious microorganisms

2. Compromised host/pathogen

interface

socket and clear running of the inferior

alveolar arteries.

showing remarkable absorption of the

Mandible or maxilla

Presence of unerupted tooth

Conservative treatment (antibiotics)

Condyle or TMJ –Severe deformities (Rowe &

Heslop 1957)

A proliferative rather than a lytic bony response is usually seen due to attenuation of the causative organisms and the improved immunological status of children in Britain.

The importance of penicillin-resistant organisms and anaerobes, early diagnosis by scintigraphy and the use of hyperbaric oxygen therapy are highlighted.

Subperiosteal bone deposition

Bone biopsies from the mandibles of 5 patients with PCO were sampled with an extraoral sterile approach. Cultivation and polymerase chain reaction (PCR) were performed.

RESULTS:

Two of the biopsies yielded growth of Propionebacterium acnes. One biopsy also demonstrated Staphylococcus capitis. The biopsies with bacterial growth were also positive for the same bacteria by PCR analysis.

Bone –granite hard ,mandible

Six patients- particulate cancellous bone and marrow grafting after saucerization

The partial resection of the mandible is associated with disadvantages- including loss of mandibular support, dysfunction, and problems related to mandibular reconstruction.

Therefore, it would be reasonable to choose saucerization combined with particulate cancellousbone and marrow grafting, which is a relatively conservative surgical treatment for chronic diffuse sclerosing osteomyelitis of the mandible.
