The fibrous dysplasia of bone is a benign, slow growing, perplexing tumor of bone that replace the normal bone by the fibrous tissue composed of collagen fibers, fibroblasts and containing variable amount of mineralization.
A fibrous dysplasia tends to occur more frequently in women than men and to be seen more in maxilla than mandible. This tumor may obliterate maxillary sinus and extend to the infraorbital area, zygoma but may not obliterate the nasal cavity. And
this
tumor may expand the cortical plate of the mandible, mandibular cannal and may involve to the condylar head so that facial asymmetry is provoked.
Ideal treatment of the fibrous dysplasia is the surgical intervention. Because it is a diffuse lesion the complete excision is difficult, so the conservative osseous contouring is recommended.
We treated two patients, one was a 18-year-old female with fibrous dysplasia in maxilla involving zygoma, infraorbital rim and maxillary sinus, the other was a 32-year-old female with fibrous dysplasia in mandibular posterior area. We operated
the
former by conservative surgery with osseous contouring and the latter by reconstructive surgery with titanium mesh and plate after mandibular resection under general anesthesia.
We obtained successful functional and esthetic results and no recurrence was seen in two years postoperative follow up.
