Endoscopic management in fibrous dysplasia of ethmoid sinus: One case report and literatures review

Abstract

Fibrous dysplasia (FD) is a sporadic skeletal disorder in which normal bone structures and marrow are replaced by fibro-osseous tissue[1]. It is classifi ed into three types: monostotic FD, polyostotic FD, and McCune-Albright syndrome[2]. The monostotic is the most common form of FD. The disease primarily affects the long bones of the patients, and may also develop in the craniofacial region. However, FD in the paranasal sinuses is uncommon. The case in this report was diagnosed as FD in the ethmoid sinus which is a rarely seen case.
