Abstract
Objective:To evaluate the subjective olfactory function in chronic sinusitis（CRS）patients with asthma after nasal endoscopic surgery and associated factors that may affect olfactory function. Methods：The study included 90 CRS patients with asthma from January 2008 to December 2020，and all of them underwent endoscopic sinus surgery（ESS）. VAS score of olfactory function before and after surgery were collected，and the data at baseline，3 months，6 months，1 year，3 years，5 years，8 years and 10 years after surgery were compared. Factors affecting olfactory function were analyzed in a generalized mixed linear model，which including age，surgical procedure，allergic rhinitis and so on.Results： The olfactory VAS scores were significantly lower at 3 months，6 months，1 year，3 years，and 5 years postoperatively compared with baseline，and the difference was statistically significant（P<0.05）.Olfactory VAS scores at 8 and 10 years postoperatively were not statistically different from baseline（P>0.05）.Age（≥60 years），aspirin intolerance syndrome，Lund-Kennedy score，modified sinus CT olfactory cleft score，and follow-up time were risk factors, and radical sinus surgery is a protective factor.Conclusion：Subjective olfactory scores in CRS patients with asthma after ESS remain relatively stable for 5 years postoperatively.Prior history of surgery did not affect postoperative subjective olfactory scores. Age，aspirin intolerance syndrome, Lund-Kennedy score，modified sinus CT olfactory cleft score, follow-up time，and surgical approach were strongly associated with subjective olfactory scores in CRS patients with asthma，and radical surgery had a protective effect on olfaction.
