Cemento-ossifying fibroma of the maxilla and maxillary sinus: A case report and literature review

Abstract

Introduction: A large group of benign bone tumors of the jaw are fibroosseous tumors. The basis of the pathophysiological processes of this type of tumor is the replacement of normal bone tissue by fibrous tissue. The cemento-ossifying fibroma (COF) belongs to this group of tumors. Case report: A rare case of COF in the maxilla end maxillary sinus in a 40-year old patient is presented. In the initial stage, COF developed asymptomatically, as most benign tumors. In later stage other symptoms appeared, first of all facial deformities of the jaw and head, ophthalmic disorders, paresthesia due to compression of the nerves, and the like. We performed subtotal maxillectomy using the Weber-Fergusson approach. Conclusion: In this case report we presented a patient with rare localisation of COF. To set a definitive diagnosis of COF, a detailed clinical examination with MSCT and angiography are required. Surgical therapy is only method of treatment. Postoperative monitoring of the patient is necessary, including control MSCT radiography.
