“…In this study, most of the SBCs are located in the posterior lingual region of the mandible, but SBCs that are located in the buccal region, anterior region, ramus mandible are displayed as rare entities. Some variations of SBC such as bilateral lesions (3,15), lesions above the inferior alveolar canal (5, 16), bilobate as two cases (case 13 and 14) in the present study (5,17), trilobate (3), and lesions without sclerotic margins (5, 18) have also been described.…”

Background: Stafne bone cavities (SBCs) are typically seen on panoramic radiographs as unilocular, rounded or ovoid shaped, welldefined corticated radiolucencies that are located between the mandibular first molar and the angle of the mandible below the inferior alveolar canal, but they may rarely have different radiographic appearances and locations. Objectives: The purpose of this study was to evaluate the imaging features of SBC presenting various typical and atypical features and to show the contribution of different imaging techniques to diagnosis. Patients and Methods: Seventeen patients who had a panoramic radiograph that revealed an image compatible with SBC were investigated in this study. In addition to panoramic radiography, lateral oblique mandible projection for three patients, cone beam computed tomography (CBCT) for nine patients, magnetic resonance imaging (MRI) for two patients were performed to determine the exact location of the cavity and to confirm the diagnosis. Results: Seventeen patients were diagnosed with SBC. Two patients had bilobed SBC, one patient had a SBC on the buccal surface of the posterior mandible, one patient had a SBC located in the ramus mandible, one patient had a SBC located in the canine-premolar region namely anterior lingual variant as rare conditions. Conclusion: Imaging techniques such as CBCT and MRI have provided detailed information about definitive diagnosis of SBC in addition to panoramic radiographs. These techniques show the size, location and content of the SBC. If the SBC is atypical, complementary imaging techniques gain more importance.

Stafne bone defects are asymptomatic lingual bone depressions of the lower jaw. In 1942, Stafne described for the first time 35 asymptomatic, radiolucent cavities, unilaterally located in the posterior region of the mandible, between the mandibular angle and the third molar, below the inferior dental canal and slightly above the basis mandibulae. In this study, the clinical and radiological characteristics of 2 cases of Stafne bone defects were described. Orthopantomograph and CBCT were used for diagnosing the defects. The bone defects of two patients in this study were asymptomatic and any other bone lesions, such as cysts and tumors, were excluded because no signs of inflammatory or tumoral changes were evident Therefore, surgery was not considered and the patients were followed for 1 year. Stafne bone defect was an incidental finding, presenting no evolutionary changes, and as such conservatory therapy based on periodic controls was indicated. Currently, complementary techniques such as CT are sufficient to establish a certain diagnosis.

“…On rare occasions, the depression may occur bilaterally 1,49 or as two adjacent, ipsilateral depressions. 38,62,69 In an attempt to clearly delineate a LP-variant radiographically, Drinnan 7 ®lled the concavity with a radiographic contrast medium. Oikarinen and coworkers, 42,46 using stereosialography, demonstrated contrast medium in a lobe of the submandibular salivary gland, part of which was situated inside a posterior mandibular bone depression.…”

The present concept favours that all variants have a common origin: a hyperplastic/hypertrophic lobe (or aberrant lobe) of the sublingual, submandibular or parotid salivary gland, exerting pressure upon the cortex of the mandible by the respective gland, leading to focal atrophy or resorption of the bone. The bone depressions take years to develop, appearing radiographically not until the 5th to 6th decades.
