An Unilateral Basal Bone Defect of the Mandible Occupied by Fatty Tissue: Stafne's Cavity

A: Large ovally-shaped defect of the right mandibular base below the mandibular canal. B: This intraoperative image was taken after detachment of the buccal periosteum from the mandible and separation of the soft tissue occupying the mandibular defect. Yellowish fatty tissue can be seen to ooze out the cavity after incision of the periosteum (right arrow). Note the facial artery (left arrow) attached to the buccal soft tissue in close proximity to the defect (9).
