Resection of Giant Cemento-Ossifying Fibroma of Jaws by Intraoral Approach—A Case Report and Review

Abstract

Introduction: The World Health Organization in 1971 first classified fibro-osseous lesions (FOLs) as cementum forming tumors of jaws as ossifying fibroma (OF), cement-osseous dysplasia, and fibrous dysplasia. Various theories have been put forward regarding the origin of cemento-ossifying fibroma (COF) but current interests are oriented toward traumatic and developmental etiologies. The COFs are a slow-growing osteoexpansile tumor which grows to a considerable size. The tumor usually arises from tooth bearing and periodontal ligament region basically of odontogenic origin. Background: An inordinate, bony hard swelling, present united in both the jaws showing radiopaque-radiolucent mass, corticated margins, with expansion of buccal as well as lingual cortex gives a delusional image for the provisional diagnosis for surgeon, particularly to decide the surgical approach. These traits showing similarity with FOLs, more particularly cemento-OF, owing to its odontogenic or periodontal origin. Case Report: In this case, a 42-year-old female presented with abovementioned features was first taken for biopsy and then planned for simultaneous surgical resection of pathology for both jaws, from an intraoral approach giving a scar-free result. Preclusion of immediate complications was dealt with reconstruction of mandible with 2.5-mm titanium reconstruction plate. Conclusion: The diagnosis of cement-OF is based on clinical-radiographic-histopathologic evaluation. If remain untreated, these tumor can grow up to an average size of 80 mm, therefore, demanding an early surgical intervention. In our case, intraoral approach leads to almost no residual fibrosed tissue. The patient is further being planned for rehabilitation with either free fibula graft or 3-dimensional mandibular prosthesis.
