Diagnosis of a Lingual Mandibular Bone Defect (Stafne’s Bone Defect) by CT Scan

The lingual mandibular bone defect, which is also known as Stafne’s bone defect, is a rare entity commonly affecting the posterior lingual part of the mandible. Although this lesion usually contains normal connective tissue compartments, it may be misinterpreted as tumor like lesions. In this manuscript, based on the density analysis of the CT images and through use of a simplified quantification system, a novel approach has been introduced which attempts to differentiate the benign nature of the defect.
