Abstract

A Rare Variant of the Stafne Bone Cavity Localized to the Subcondylar Region of the Mandible: A Case Report with Review of the Literature

Highlights

  • Stafne bone cavity (SBC) is classically described as an asymptomatic depression or concavity localized on the medial surface of the posterior mandible between the inferior alveolar canal and inferior border.[1]

  • The most common location is the medial surface of the posterior mandible in the region of the submandibular gland fossa,[1, 3, 4]

  • The most common location is the medial surface of the posterior mandible from the first molar to the angle

Summary

Introduction

Stafne bone cavity (SBC) is classically described as an asymptomatic depression or concavity localized on the medial surface of the posterior mandible between the inferior alveolar canal and inferior border.[1]. The incidence of the SBC has been reported to range from 0.1 to 6.06%.7 The goal of this case report is to present a variant of the Stafne bone cavity localized to the medial surface of the right subcondylar neck of the mandible in our patient discovered during completion of a routine panoramic radiograph. Panoramic radiograph revealed a unilocular, well-circumscribed radiolucency in the right subcondyalar region of the mandible that was close to the posterior border of the condylar neck (Figure 2). Cone beam CT scan (i-CAT FLX, Imaging Sciences, Hatfield, PA) imaging revealed a well-defined unilocular, elliptical shaped radiolucent lesion on the medial surface of the right subcondylar neck of the mandible (Figure 3, 4, 5).
