A case of a so-called static bone defect of the ascending ramus

Abstract

So-called static bone defects are usually situated in the molar or angular regions of the mandible. A rare case of a so-called static bone defect which existed in the ascending ramus of the mandible of a 25 year-old female is reported. X-ray findings showed a cyst-like radiolucent lesion in the ascending ramus but computed tomography and magentic resonance imaging proved that the lesion was a defect on the lingual ramus with anomaly of the mandible. Histopathological examination revealed the lesion to contain fatty tissue.
