Stafne bone defect in the anterior mandible

Abstract

Lingual mandibular bone defect, also known as Stafne bone cavity, is mostly seen in the posterior portion of the mandible. Cavities in the anterior region are very unusual, with around 50 cases reported in the English literature. They are often asymptomatic and found during routine radiographic examinations. This article describes a case of anterior Stafne bone cavity in a 56-year-old male patient.

Cone‐beam computed tomography analysis of lingual mandibular bone depression in the premolar region: A case report

“…In this case report, the mean (± standard deviation) gray scale value of the MBD was approximately 108 (±31), considering the fact that sublingual secretions are predominantly mucinous. This defect can be classified under the category of soft tissues, in concordance with previous reports that examined MBDs with surgery and MRI and found inflamed connective tissue, fatty tissue, striated muscle, and salivary gland tissues in its histopathological analysis . However, studies with larger sample size are required to achieve more appropriate conclusions.…”

“…In the premolar area of the mandible, MBDs are often located in the periapical region, sometimes superimposed over the roots and sometimes between or below the roots . Therefore, they may be misdiagnosed as other radiolucencies or more frequently as cysts (ie, radicular, residual or lateral periodontal cyst, traumatic bone cyst or odontogenic keratocystic), various benign tumors (ameloblastoma), or even bone metastases . Most defects are asymptomatic and nonprogressive.…”

In this case report, this defect was unilocular, in concordance with other studies; however, in the literature, multilocular defects have also been reported, which complicate the diagnosis of MBDs.…”

Lingual mandibular bone defect: imaging features in panoramic radiograph, multislice computed tomography and magnetic resonance imaging

“…Lingual mandibular bone defect: imaging features in panoramic radiograph, multislice computed tomography and magnetic resonance imaging INTRoDuCTIoN S tafne bone cavity or mandibular bone depression (MBD) is defined as a bone developmental defect which is filled with soft tissue, usually salivary gland [1,2] or fat tissue. MBD may present four different variants: lingual posterior [3], lingual anterior, lingual ramus and buccal ramus [4,5].…”
