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 31-year-old asymptomatic male patient was referred to Secunderabad Dental Imaging Centre (Hyderabad, India) to undergo routine panoramic radiography. The panorama revealed a cystic lesion in the left posterior mandible just anterior to the mandibular angle and below the third molar and mandibular canal.() There was no significant medical or dental history. 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 located below the mandibular canal and measured 11.8×8.4×14.1 mm (height×breadth×length).() The long axis of the lesion was placed horizontally on the left side. The cross-sections revealed a close relationship with the mandibular nerve without any pressure effect.() The patient was asymptomatic and there was no parasthesia or anaesthesia. The buccal wall was intact and there was no expansion (); however, the lingual wall was involved. The inferior border was also intact with little pressure atrophy.\nA radiographic diagnosis of SBC was considered and the patient was advised to undergo regular follow-up examinations.
