Abstract

Abstract: Stafne's Bone Cavity (SBC) is a well described but uncommon asymptomatic pseudocyst of the mandible. Most commonly occurring in the posterior mandible, presentations anterior to the mental foramen are extremely rare and warrant thorough investigation. This case describes the presentation of a 55-year-old male with an anteriorly-positioned SBC that resembled asymptomatic dental pathology. Clinicians should be aware of SBCs as a differential diagnosis for radiolucent lesions of the mandible.

CPD/Clinical Relevance: To raise awareness of radiolucent lesions to dental professionals in both general and specialist settings.

Article

A 55-year-old male was referred to the Oral and Maxillofacial Surgery (OMFS) Department at St George's Hospital by his general dental practitioner for further investigations of an incidental finding of a radiolucency of the anterior mandible. The patient's medical history was unremarkable; he was a non-smoker and revealed no history of previous facial trauma or surgery. Initial examination revealed a moderately restored adult dentition with average oral hygiene. There was neither pain nor swelling of the buccal and lingual sulci of the mandible, and no cervical lymphadenopathy. All teeth were vital, non-mobile, not tender to percussion and no caries was identified.

An orthopantomogram (OPG) showed a well-defined, unilocular radiolucency below the apices of an unrestored and non-carious lower left first premolar (LL4). It was decided that a cone beam computed tomogram (CBCT) would be beneficial in diagnosing this lesion and in treatment planning; three-dimensional views allow an accurate assessment of size, location, and proximity to vital structures. Although not a routine imaging modality for SBC, we decided that, as we did not have a definitive diagnosis of SBC from the OPG, it would be necessary should any surgical intervention be required (Figures 1 and 2).
