Do Eosinophilic Polyps Act as a Reliable Predictor of Olfactory Dysfunction and Postoperative Recovery in Chronic Rhinosinusitis?

다국어 초록 (Multilingual Abstract)

Background and Objectives The purpose of this study was 1) to assess differences in categoriesof olfactory dysfunction according to the pathological classification of chronic rhinosinusitiswith nasal polyp (CRSwNP) patients; 2) to identify the degree of olfaction recoveryafter endoscopic sinus surgery (ESS); and 3) to identify the factors that predict the changes inolfactory status.
Subjects and Method The sample of the study consisted of patients with CRSwNP whounderwent ESS with biopsy from January 2012 to September 2014. Seventy five patients wereclassified into eosinophilic CRS (ECRS) and non-ECRS groups. During an approximately fivemonthfollow-up, the Korean Version of Sniffin’ Sticks test II (KVSS II) was conducted oneach patient to examine the difference between the preoperative and postoperative states of olfactoryfunction.
Results The ECRS group showed a statistical significant increase in the postoperativeKVSS II scores when compared to the preoperative scores, while the non-ECRS group did notshow any statistically significant change. For the anosmia category by KVSS II, the ECRSgroup showed significantly improved olfactory function test scores for the threshold, discrimination,and identification tests.
Conclusion ECRS and preoperative olfactory function status (anosmia) could be predictablefactors of postoperative olfactory function.
