Fibrous dysplasia is a benign condition characterized by an increase in fibrous tissue and bone tissue. In the field of otolaryngology, its development is often encountered in the maxillary bone and lower jaw.
Here we report a case of 56-year-old male with fibrous dysplasia in the ethmoid sinus. Computed tomography (CT) revealed a space-occupying lesion of high absorption from the ethmoid sinus to the orbital area.
The dysplasia was totally extirpated with an external nose incision, and was diagnosed histopathologically as fibrous dysplasia of the bone. One year postoperatively, no palindromia has been observed.
The development of fibrous dysplasia in the ethmoid sinus is rare.
Key words : fibrous dysplasia, ethmoid sinus
