Olfactory cleft and sinus opacification differentially impact olfaction in chronic rhinosinusitis.

ABSTRACT:

Objectives

Prior studies have indicated that olfactory cleft (OC) opacification correlates with olfaction in patients with chronic rhinosinusitis (CRS). However, the results have been unclear in patients without polyps. The purpose of this study was to further explore the relationship between OC opacification, sinus opacification, and olfactory function in patients with CRS.

Methods

One hundred and forty-eight patients with CRS were prospectively enrolled across five institutions. Olfactory function was evaluated using the Sniffin' Sticks tests (Burghardt, Wedel, Germany) and the 17-item Questionnaire of Olfactory Disorders (QOD-NS). Computed tomography (CT) scans for each patient were acquired and Lund-Mackay scores recorded. Opacification of the OC was determined using Osi
