Abstract
This study describes the peroperative endoscopic findings about the size, shape and mucosal changes of the middle turbinate in patients with chronic sinusitis who underwent total spheno-ethmoidectomy. Results confirmed the middle turbinate to be a useful landmark in performing extensive sinus surgery. The most frequent change due to chronic inflammation seems to be polypous degeneration followed by hyperplastic mucosa. Anatomical variations, being paradoxically bent turbinate and concha bullosa, are not seen frequently.
