 Clinically, buccal exostoses appear as single, broad-based masses, usually situated bilaterally in the premolar and molar region on the facial surface of the maxillary alveolar bone.The mass is generally smooth although in some cases a sharp, bony prominence may be present resulting in tenderness beneath the mucosa.Initial presentation usually occurs in early adolescence and the lesions may slowly enlarge up to 3-4cm in diameter with time, however there is no malignant potential.
