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.
A 35-year-old male patient was similarly referred to Secunderabad Dental Imaging Centre (Hyderabad, India) to undergo routine panoramic radiography. The panorama revealed a cystic cavity on the left side below the second molar and mandibular canal, anterior to the angle of the mandible. () Medical and dental history was not contributory. There was no tenderness on bidigital palpation at the site of the lesion. For further analysis, CBCT restricted to the area of lesion was performed. The results revealed a complete radiolucent lesion that was regular, oval in shape, and well corticated.() The lesion was situated below the mandibular canal and measured 4.7×12.7×16.6 mm (height ×breadth×length).() The long axis of the lesion was situated horizontally in the left side. Cross-sections revealed a mandibular canal within the lesion without any pressure effect.() The patient was asymptomatic and there was no parasthesia or anaesthesia. The buccal wall and the inferior border were intact and there was no expansion (); however, the lingual wall was involved and the inferior border showed some pressure atrophy.\nA radiographic diagnosis of SBC was considered and the patient was recommended for regular follow-up.
