Fibro-osseous Lesions in the Maxillofacial Region

Abstract

Fibro-osseous lesions have posed a diagnostic dilemma since the beginning when the first case was reported in the late nineteenth century. Since then, various lesions are included in this group, yet the understanding of the lesions remains obscure for the clinician/surgeon. The main reason for this is their histological resemblance with one another, where they all show varying degrees of healthy bone replaced by fibrous tissue and some amount of bone/cementum-like tissue intermingled in between. This chapter is written with the aim of simplifying these groups of bony lesions for its readers and highlighting the key idea of interdisciplinary approach in the management of these lesions where the oral pathologist along with radiologist and clinician plays a pivotal role in differentially diagnosing these lesions, for the maxillofacial surgeon to choose and perform her/his duty of managing them, rightfully, for their patients. The spectrum of these lesions has seen several changes during the course of history yet there is still ample scope for ambiguity in identification and classification of the lesions, hence the authors have chosen few most commonly encountered lesions in the Indian subcontinent, for the description and discussion.

Juvenile psammomatoid ossifying fibroma with fluid–fluid levels: an unusual presentation

“…Another common differential is cemento osseous dysplasia. It is commonly seen in tooth-bearing areas especially in the alveolar process of the maxilla and mandible, which confirms the odontogenic origin of the lesion [10]. It does not cause bony expansion [7].…”

Implant Placement on a Cementoosseous Dysplastic Mandible with a Long-term Follow-up: A Case Report

“…Furthermore, as the affected teeth maintain their vitality, the diagnosis of this condition is often. 2 Radiographically, COD presents with well-defined margins, central radiopacity, and an amorphous shape. The visibility of radiopacity may vary depending on the stage of maturation.…”

“…local factors can potentially trigger osteomyelitis in the underlying bone. 2 In addition to periodontitis, extractions, or ill-fitting dentures, the relatively recent advancement in dental technology, such as dental implants, could potentially contribute to the progressive infection of COD.…”

Cherubism Unmasked: A Case Report of Clinical and Histopathological Presentation

“…OF necessitates complete removal from the surrounding bone due to its increased risk of recurrence. Conversely, FD is managed conservatively because it tends to resolve on its own [ 4 ].…”
