A 66-year-old healthy man was referred from a private dental clinic for evaluation of a multilocular radiolucency at the left molar region of the mandible. Panoramic radiograph revealed a well-defined multilocular radiolucent area under the mandibular canal at the distal root of the second molar tooth (). The lesion showed three lobulated radiolucencies with radiopaque margins in the region of the submandibular gland fossa. On clinical examination, there was no sign of infection, fistula, or nerve damage. No history of expansion on the left mandibular angle area was recorded. The patient had no systemic disease and no specific medical history.\nCBCT scan was recommended for further study. Axial CBCT images showed a lingual bony defect located at the lingual side of the mandibular canal (). Coronal CBCT images showed a lobulated bony defect below the mandibular canal (). The maximum mesiodistal length of the defect was 14.16 mm, and the height was 7.38 mm. The maximum buccolingual length of the defect was 4.44 mm, not showing the expansion or thinning of the buccal cortical bone.\nParasagittal CBCT images showed three lobulated radiolucencies with radiopaque margins between the mandibular canal and the inferior border of the mandible (). Three-dimensional, reformatted CBCT images revealed a bony defect extending from the medial surface of the mandible ().\nThe lesion was diagnosed as a developmental salivary gland defect from the radiographic features. The patient was informed about the lesion and was scheduled for follow-up.
A 52-year-old female patient presented with facial injury suspicious for nasal bone fracture. During facial bone computed tomography (CT), a well-circumscribed cystic lesion was discovered incidentally on right side of the mandible (). The patient did not complain of any discomfort, pain, or numbness of the lower face. She also denied any trauma to the chin or significant surgical history.\nLateral radiographs showed a well-defined, radiolucent, ovoid lesion anterior to the right mandibular angle (). The coronal and sagittal CT images demonstrated a deficiency in the mandibular defect containing the soft tissue lesion in continuity with the submandibular gland (). Based on the radiological findings, the patient was diagnosed with a Stafne bone cavity, and regular observation was recommended.
