Most investigators believe that fibrous cortical defects and nonossifying fibromas are simply different radiographic manifestations of the same disease process. Fibrous cortical defects are small, asymptomatic, and intracortical lesions, while a nonossifying fibroma is a large, tumorous lesion involving spongy bone and the medullary cavity of bone, and leads to clinical symptoms.
A fibrous cortical defect does not require either biopsy or curettage. Asymptomatic nonossifying fibromas require no treatment, but rare symptomatic forms of the disease, and those which are great enough in size to constitute a danger of fracture, should be submitted for curettage and bone grafting.
