A buccal exostosis (also termed alveolar exostosis),[1] is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible. Some consider them a variation of normal anatomy rather than a disease.
Signs and symptoms
Formation on the lower jaw occurs much less commonly than on the upper jaw.[2] They are painless[3] and have no risk of turning into cancer,[4] although they may slowly expand over years,[5] or sometimes more rapidly.[6]
Causes
Why buccal exostoses form is unclear,[2] but it may involve bruxism (tooth clenching and grinding),[2] and genetic factors.[6] Typically they first appear in early adulthood.[5]
Diagnosis
Buccal exostoses are considered different entities to osteomas (e.g. seen in Gardner syndrome),[6] even though the two lesions are histopathologically identical.[7]
Management
Generally buccal exostoses require no treatment. However, they may be easily traumatized causing ulceration,[6] or may contribute to periodontal disease if they become too large,[4] or can interfere with wearing a denture (false teeth).[2] If they are creating problems, they are generally removed with a simple surgical procedure under local anesthetic.[8]
Epidemiology
They are more common in males than females, occurring in a ratio of about 5:1.[6] They are strongly associated with the presence of torus mandibularis and torus palatinus.[6]
