A Rare Case of Mandibular Exostoses and its Review

摘要

Mandibular exostosis is a type of bony prominence caused due to hyperostosis in the mandibular bone. They are benign, broad-based surface masses on the outer or facial aspect of the jaw bones; slowly enlarge over the years to form the bulky masses. During the period between the 10th to 13th week of intrauterine life, changes in the structure of the Meckel’s cartilage and the protrusion of the medial lamina of the mandible onto the cartilage can result in the formation of such exostosis. We discuss here a very rare case of a 49-year-old male, in which the buccal exostoses formed underwent changes in size and shape due to certain factors, resulting in a bony bar formation in the mandibular anterior region.
