Osteogenic and odontogenic tumors in the maxillofacial area sometimes involve the orbit or skull base and are clinically malignant, even if the histology is benign.We report four cases of such extensive tumors: fibrous dysplasia, cementifying pibroma, osteoma and chondroma.Our patients are described and the past literature is reviewed. Ophthalmological and multiple craniall nerve symptoms are frequently noted, so these tumors are considered to be clinically malignant.These tumors cannot readily be diagnosed by conventional X-ray examinations. Bone target CT scans revealed characteristic patterns in each of our patients. Therefore, we recommend bone target CT scans for the differential diagnosis of osteogenic and odontogenic tumors.Treatment is also discussed. Conservative operations for cosmetic and functional restoration are appropriate for these histologically benign tumors.
