Stafne Bone Cyst of Mandible - A Rare Pseudocyst

Abstract

Background: Stafne bone cyst (SBC) is a bone depression found on the lingual side of the mandible. It is usually asymptomatic and is usually diagnosed on the routine radiographs as an incidental nding. So it has an unknown prevalence. The lesion resembles many odontogenic pathologies and the entity remains a diagnostic challenge. The aim of this case report is to describe the clinical and radiological characteristics of a case of stafne bone cyst and the importance of cone beam computed tomography in conrming the diagnosis. Method: Analysis of orthopantomogram (OPG) and cone beam computed tomography (CBCT) was done on the basis of diagnostic criteria described by Stafne. Result : According to the clinical and radiographic ndings and based on the dental literature, it was concluded that the observed bony cavity was a Stafne bone defect, located in the angle of mandible below inferior alveolar canal. Conclusion: Differential diagnosis of SBC's from other possible pathologies that may require treatment and imaging technique selection according to case is signicant. The use of CBCT is highlighted because of the ne detail of imaging , low radiation dose and limited area exposure which is benecial for the diagnosis of SBC.
