Aim of the study was to investigate the outcome of olfactory function in patients with olfactory loss following infections of the upper respiratory tract (post-URTI). In this retrospective patient based study, a total of 262 patients (187 female, 75male; mean age 58 years) were included. Olfactory function was assessed using the “Sniffin’ Sticks” test battery. The mean interval between first and last visit was 14 months.
Comparing overall scores between last and first visit olfactory function improved in 32% of the patients. In 63% of the patients no change in olfactory function was observed. In addition, a negative correlation was found between age and recovery of olfactory function. In general, sex had no significant effect on recovery of smell function.
Over 30% of patients with post-URTI olfactory loss experience improvement during an observation period of approximately 1 year. Further, age, but not sex, plays a significant role in the recovery of olfactory function.
