[The value of ultrasonography and computerized tomography in mandibular diseases: apropos of 2 cases of chronic fistulizing mandibular osteitis].

Though US and CT are infrequently used for the detection of mandibular disease, both techniques definitely contributed to the detection and extension work-up of fistulizing chronic mandible osteitis in our 2 patients. US clearly visualizes the mandible margin and enables detection of abnormal foramina. CT is highly valuable for the visualization of the complex (flat and curved) structure of the mandibular body and the adjacent soft tissues. While routine intraoral radiography remains necessary and sufficient in easy pathological conditions, it appears from our experience that CT and US are of unique value in detecting complex or complicated mandibular disease, in particular when involving the surrounding soft tissues.
