Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Oral exostoses are benign boney growths on the mandible or hard palate, including tori and buccal exostosis. Tori are benign nodular overgrowths of cortical bone, occurring in the midline of the palate where the maxilla fuses (palatinus) or on the mandible, typically on the lingual aspect of the molar teeth (mandibularis). Although their physical appearance may be alarming, there is generally no need for concern. Tori are covered by a thin epithelium, which is easily traumatized and ulcerated. These ulcerations tend to heal very slowly because of the poor vascularization of the tori. Torus palatinus, in particular, is slow growing and may occur at any age; however, it is most commonly noted prior to age 30 in adults and affects women twice as frequently as men. Buccal exostoses are typically found on the buccal surface of the maxillary or mandibular alveolar ridge adjacent to premolar teeth. There are a variety of oral conditions that may be confused with exostoses. Gingival fibromatosis, fibroma formation secondary to irritation, granulomas, abscesses, and oral neurofibromatosis located on the palate may resemble torus palatinus. Nodular bony enlargement in the oral cavity may also result from fibrous dysplasia, osteomas, and Paget disease. Oral malignancies may manifest themselves on the palate as primary lesions, although these are rare. Oral radiographs, CT scans, and biopsy may aid in differentiating these conditions.
