Abstract

Stafne bone cavity containing ectopic parotid gland

Highlights

In 1942, Stafne[1] described 35 asymptomatic cases of a cortical depression of the lingual side of mandible with unilateral radiolucent cavities located in the posterior region of the mandible, between the third molar and mandibular angle, below the inferior mandibular canal and above the mandibular base
As its controversial pathogenesis explanations, this lesion has been called of many names including static bone cavity or defect, latent or idiopathic bone cavity, ectopic submandibular or sublingual gland in the mandible, lingual cortical mandibular defect or depression, developmental bone defect of the mandible and Stafne cyst, defect or cavity
There are reports of patients operated for this entity, with descriptions of cavities containing submandibular gland tissue, muscles, fibrous connective tissue, blood vessels, fat or lymphoid tissue.[2]. In this particular paper we present a Stafne bone cavity containing ectopic parotid gland

Summary

Introduction

In 1942, Stafne[1] described 35 asymptomatic cases of a cortical depression of the lingual side of mandible with unilateral radiolucent cavities located in the posterior region of the mandible, between the third molar and mandibular angle, below the inferior mandibular canal and above the mandibular base. The lobulated mass showed diffuse contrast retention and intermediate density in T1A sections, hyperintensity in T2 images and did not suppressed in fat suppressed series This mass was filling the space situated anteriorly to the right mandibular angle, formed as a well-bordered cortical depression with an intact inferior mandibular line (Fig. 1). Thereafter we again looked at MRI images to verify if both parotid glands were present in their usual locations
