DROGUETT TIDY, Christian et al. Mandibular giant ossifying fibroma: report of a case with mandibular reconstruction using a free microvascular fibula flap and osteointegrated grafts. Rev Esp Cirug Oral y Maxilofac [online]. 2012, vol.34, n.3, pp.122-127. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2011.09.005.

Ossifying fibroma (OF) is an uncommon fibro-osseous lesion that generally affects middle-aged women and is usually located in the posterior jaw. Clinically, the patient may present a slow-growing, asymptomatic mass with tooth displacement as an early manifestation. Radiographically, OF is characterized as a radiolucent lesion in its early stages that progresses to a mixed lesion with variable radiopaque areas and finally evolves into an extremely radiopaque lesion. Treatment depends on the size of the tumor and ranges from conservative surgery to block resection followed by reconstruction with bone grafts. The specific clinical and histological characteristics of the case of a 22-year-old patient with a large OF are described. The case is reported here due to the tumor extension and therapeutic approach consisting of block resection of the affected jaw segment followed by reconstruction with a free microvascular fibula flap.
