Abstract
Background: Paranasal sinuses are lined by the respiratory mucosa which is psuedostratified ciliated columnar epithelium. Cholesteatoma of maxillary sinus is characterized by alteration in the normal respiratory epithelium which gets replaced by the hyperkeratotic squamous epithelium leading to the formation of  sheets of keratin and this is known as nasal cholesteatoma which has the property to erode the adjacent bony structures and should  be considered as differential diagnosis of other nasal conditions of gradual expanding masses of the maxillary sinus. We are reporting one such case of 44yrs old female patient who presented with unilateral nasal obstruction diagnosed as maxillary sinus cholesteatoma with aid of CT scan nose & PNS and successfully corrected surgically.
