Recurrent ossifying fibroma of the sphenoid bone 26 years after primary surgical excision; a case report and review of the literature.

摘要

We recently treated a patient through our craniofacial unit who presented with a recurrent intracranial ossifying fibroma (OF) 26 years after her original surgery, which appears to be the longest interval reported in the literature. OFs are benign bony lesions that present predominantly in females with a painless, slow-growing, expansile mass of the mandible (70 %) or maxilla (24 %). They exhibit progressive proliferation and expansion with well-defined radiological margins and are thought to arise from the periodontal membrane surrounding the roots of teeth.
