Oral maxillary exostosis

Abstract

Oral maxillary exostoses are proliferating bone lesions with an unknown etiology occurring on the cortical plates both in the maxilla and in the mandible of young individuals, showing a typical slow but continuous enlargement. No treatment is usually required unless they create esthetic or functional limitations during follow-up; the biopsy is needed only for doubtful lesions. Furthermore, it is mandatory to collect an accurate familiar history of patients affected by exostosis, especially when occurring with atypical clinical presentation, in order to exclude or prevent potentially associated systemic diseases.

Keywords: benign bone lesions; maxillary exostosis.
