“…In the present report, these imaging features are present and depression limits are defined by a thin sclerotic discontinuous border. The LMBD is continuous to mandible base, as also demonstrated in a previous report [19], which mandible base similarly presents discontinuity of its cortical bone. However, in literature, we also found reports with thick LMBD margins, continuous to the mandible base, without any cortical interruption [20,21].…”

Stafne bone defect or mandibular bone depression is defined as a bone developmental defect usually filled with soft or salivary gland tissue. Lingual posterior variant incidence is less than 0.5%. We reported a case of an 80 years old Asian female asymptomatic patient who underwent routine panoramic radiographic examination and a radiolucent area in mandible was noticed as an incidental finding, with an initial provisional diagnosis of traumatic bone cyst, aneurysmal bone cyst and lingual mandibular bone defect. The patient was then referred to multislice computed tomography and magnetic resonance imaging. Computed tomography showed a hypodense area with discontinuity in mandible base. Magnetic resonance imaging demonstrated a hyperintense image eroding mandibular body in contact with submandibular gland, which corresponded to fatty tissue and due to these imaging findings, the final diagnosis was lingual mandibular bone defect. Although the defect is a benign lesion and interventional treatment is not necessary, radiolucencies in mandible should be detailed investigated, due to their radiographic features that can resemble to other intrabony lesions. Imaging examinations can provide great defect details, especially magnetic resonance imaging, which can allow the identification of glandular tissue continuity to the mandibular defect.KeywordsBone cysts; Salivary glands; Magnetic resonance imaging; Computed tomography; Panoramic radiography.

“…10 The case presented by Mann and Shields 10 was an archeological sample from their study of 6700 excavated dry mandibles. Lee et al 11 reported a case in Australia, in which the patient had mild hemifacial macrosomia type I, a hypoplastic right mandible and TMJ. Incidentally, his parotid salivary gland was enlarged (hypertrophic) and observed to be occupying part of the right ascending ramus.…”

Developmental salivary gland depression in the ascending mandibular ramus: A cone-beam computed tomography study

et al. 2016

A static, unilateral, and focal bone depression located lingually within the ascending ramus, identical to the Stafne's bone cavity of the angle of the mandible, is being reported. During development of the mandible, submandibular gland inclusion may lead to the formation of a lingual concavity, which could contain fatty tissue, blood vessels, or soft tissue. However, similar occurrences in the ascending ramus at the level of the parotid gland are extremely rare. Similar cases were previously reported in dry, excavated mandibles, and 3 cases were reported in living patients. A 52-year-old African American male patient was seen for pain in the mandibular teeth. Panoramic radiography showed an unusual concavity within the left ascending ramus. Cone-beam computed tomography confirmed this incidental finding. The patient was cleared for the extraction of non-restorable teeth and scheduled for annual follow-up.

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

An anatomical variant of the Stafne bone cavity (SBC) located in the right subcondylar region of the mandible is presented. Such an occurrence of the SBC in this region near the parotid gland is considered rare and poses a diagnostic challenge for the dentist and radiologist. Knowledge of head and neck clinical anatomy and imaging studies such as plain film panoramic radiographs and cone beam CT scans can assist the clinician in arriving at a correct definitive diagnosis without surgical intervention.
