Cemento-Ossifying Fibroma in Maxillofacial Region: A Series of 16 Cases.

Abstract

Cemento-ossifying fibroma is considered as a benign osseous tumour, closely related to other lesions such as fibrous dysplasia and cementifying periapical dysplasia. These lesions occur in the second to the fourth decade of life. It is a bony tumour of maxilla and mandible of possibly odontogenic origin with aggressive behaviour and high tendency for recurrence. Radiologically, the lesion appearances varied ranging from radiolucent cyst-like appearance to mixed and/or radiopaque areas. The article attempts to highlight the importance of clinical, imaging aspects and histopathology in diagnosis of cemento-ossifying fibroma along with management and long-term follow-up. This retrospective study was done on histologically diagnosed 16 fibro-osseous lesions. These patients were treated under general anaesthesia at our institute. The demographic data, radiographic features, and histopathologic findings were analysed and compared. The treatment and follow-up data were also recorded. Cemento-ossifying fibroma showed higher predilection for female than for male patients and with an equal number of cases reported in maxilla and mandible with no signs of recurrence in long-term follow-up of 15years. Complete surgical excision of cemento-ossifying fibroma comes out to be only effective treatment that gave satisfactory results and can be considered as a definitive treatment modality.
