Abstract: Introduction: Fibrous dysplasia (FD) is a slow-growing, benign fibro-osseous tumor with a recurrent character distinguished by replacement with fibrous connective tissue instead of normal bone. The medullary bone is substituted by fibrous connective tissue, leading to immature, poorly mineralized bone. FD is responsible for approximately 2.5% of all bone tumors and 7% of all benign bone tumours. Patients may show involvement of one bone (monostotic FD; MFD) or multiple bones (polyostotic FD; PFD). The present case report describes FD's clinical, imaging and therapeutic aspects in the maxillary and mandibular region. Case: = 4) patients underwent surgical procedures: 2 patients in the mandibular region, one in the maxillary region, and one in the maxillary and mandibular region. No complications occurred at the six-month follow-up. Case management: The diagnosis of FD is established based on clinical, radiographic, and histopathological features. Imaging analysis showed an expansive, non-destructive mass, with a well-circumscribed cortical and appearance of ground glass, involving either the maxilla or mandible. After diagnosis of FD, 3 patients undergo a conservative bone reshaping surgical procedure, and 1 patient undergoes a surgical resection and bone reshaping with primary wound closure. Conclusion: The diagnosis of FD remains challenging because of its clinical, imaging, and histological similarities with other fibro-osseous tumors. A conservative approach of bone reshaping could be adopted as the first line of treatment for patients suffering from FD. A complete surgical removal by resective surgery and immediate reconstructive procedures also produces satisfactory clinical results after adequate follow-up.
