Stafne bone defect (SBD) or as sometimes called "cavity", is a rare, unilateral, mostly unilocular, asymptomatic bone depression found at the posterior part of the mandible, below the mandibular canal at the level of the molars. It is usually being depicted at plain radiographs as a round-shaped or oval-shaped radiolucency. It is diagnosed in adults between the fifth and seventh decade of life, with a male to female ratio of 6:1 and with a prevalence of 0.10%-0.48%. The differential diagnoses include a plethora of benign or malignant conditions. Thus, multilevel radiological methods such as computed tomography (CT), cone beam CT (CBCT) or magnetic resonance imaging (MRI) may help establish its diagnosis. Soft tissues are usually contained inside an SBD, including salivary gland tissue, fat, blood vessels, fibrous tissue and nerve bundles. The main purpose of the present article is to introduce SBD not as a pathology but as an anatomical variant, to present a case of an SBD found on a dry mandible during skeletal examinations, reviewing meanwhile the available international literature.
