Ultrasonography evaluation of bone lesions of the jaw.
The ultrasonographic aspects of 72 intraosseous lesions of the jaws were evaluated to identify the usefulness of this type of examination. The principal aim of ultrasonography was to recognize the lesion's content before surgical treatment. Four groups of lesions were classified after the definitive histopathologic examination: lesions with solid, liquid, dense liquid, and mixed contents. The initial ultrasonography examination was in agreement with the histopathologic findings in 24 (92.3%) cases with solid content, 17 (73.9%) cases with liquid content, 7 (7.7%) cases with dense liquid content, and 13 (92.8%) cases with mixed content. On the basis of the results of this study, we propose the use of ultrasonography as a complementary examination for intraosseous lesions of the jaws. If a liquid component is identified in ultrasonography, a surgical procedure should be performed immediately. Otherwise, if a lesion with solid component is identified, it should be biopsied for histopathologic examination and final diagnosis before definitive surgery.
