Radio-pathological study of osteomyelitis of the jaw bones

A clinicoradiological study of maxillary osteomyelitis.

“…Comparison of radiological signs between the present cases of maxillary osteomyelitis (Table 3) and those of mandibular osteomyelitis described by YAMAMOTO et al [12] (Table 4) showed that osteolytic change in both jaws occurred with almost equal incidence, although the spotty type was predominant in the maxilla. If inflammation of the mandibular bone occurs, it could spread widely and diffusely along the mandibular canal including some of the bone marrow.…”

“…The ratio of mandibular to maxillary osteomyelitis cases was about 3. 7 : 1.0 (41 : 11 cases) in the present study (Tables 3 and 4), as mentioned below [12]. The reason why this condition is relatively rare in the upper jaw is not clear, but may be due chiefly to the anatomical and histological differences between the two jaws.…”

“…Osteomyelitis is a common disease, and most reports are of mandibular cases [7][8][9][10][11][12]. Reports of osteomyelitis in the upper jaw are relatively rare [2,4].…”

“…In both maxillary and mandibular osteomyelitis, clinical features such as patient age and sex distributions are almost the same (Table 1). As for the locations (Table 2), the bone marrow in the maxilla is chiefly located in the molar area including the tuberosity, so that maxillary osteomyelitis generally occurs in the molar area [12].…”
