A Case of Monostotic-Type Fibrous Dysplasia in the Sphenoid Sinus / 대한이비인후과학회지

ABSTRACT

Fibrous dysplasia is a rare fibro-osseous lesion characterized by replacing the skeletal structure. Its main feature is the involvement of one or several bones of the skeletal and extra-skeletal systems. Fibrous dysplasia arising in the paranasal sinus is rare, especially in the ethmoid and sphenoid sinuses. Only one case of fibrous dysplasia originating in the sphenoid sinus have been reported in the regional and international literature. Recently we experienced a case of monostotic fibrous dysplasia which derived from the sphenoid sinus in a 33-year-old female. So the case will be discussed with literature review.
