Buccal exostoses are benign, broad-based surface masses of the outer or facial aspect of the maxilla and less commonly, the mandible. They begin to develop in early adulthood and may very slowly enlarge over the years. They are painless and self-limiting, but occasionally may become several centimeters across and then contribute to periodontal disease of the adjacent teeth by forcing food during chewing in toward the teeth instead of away from them, as is normally the case. The following paper presents a very rare case of buccal-sided mandibular angle exoxtosis and its management with surgical exploration.
