The surgical management of monostotic fibrous dysplasia of the inferior turbinate

Abstract

Fibrous dysplasia is a non-neoplastic, sporadic, slowly progressing disease of the bone in which normal bone is replaced by abnormally overgrowing lesions. There are three different types of fibrous dysplasia: monostotic (affecting a single bone), poliostotic (affecting multiple bones) and syndromic, when it is associated with other diseases (such as McCune Albright syndrome). Fibrous dysplasia affects cranio-facial bones in 10% of the cases. However, its occurrence in the inferior turbinate is extremely rare. To the best of our knowledge, only four cases of monostotic form have been reported so far. Hereafter we describe a case of monostotic FD of the inferior turbinate surgically treated with a trans-nasal endoscopic partial maxillectomy type II.
