Bilateral Stafne Bone Defect: An Incidental Radiographic Finding with Clinical Implications

Abstract

Introduction: Unilateral concavities in the posterior mandible are commonly known as stafne bone defects. Bilateral appearance is uncommon &, if misinterpreted, could result in needless diagnostic procedures by mimicking pathological lesions on radiographs. Here we present a rare case of bilateral Stafne bone defect (SBD), an asymptomatic mandibular radiolucency typically discovered incidentally, & to discuss its diagnostic relevance & clinical implications.

Case Report: A male patient, age 55, was referred for a standard dental examination. Bilateral, distinct, radiolucent lesions were seen on a panoramic radiograph below the inferior alveolar canal, close to the mandibular angle. The patient had no history of mandibular disease or trauma & was asymptomatic. The discovery of bilateral lingual cortical deficits with intact cortication & no indication of soft tissue pathology, consistent with SBD, was verified by cone-beam computed tomography (CBCT). There was no surgery done.

Conclusion: Bilateral Stafne bone abnormalities must be identified in order to prevent incorrect diagnoses & needless medical intervention. In order to confirm the diagnosis & rule out alternative mandibular diseases, CBCT is essential.
