| Popis: | Introduction Acute upper respiratory infection (AURI) is the most common cause of postinfectious olfactory dysfunction (PIOD). Objective We investigated the prevalence of PIOD in a large group of patients reporting persistent smell impairment perception after the AURI resolution. Methods Olfactometry was performed within 1 month after the common cold resolution and after 1 year in 467 (299 males, mean age 41.7 years) outpatients. The Sniffin' Sticks olfactory test (Burghart instruments, Wedel, Germany) was used. Results Anosmia was documented in 28 (6%) patients, hyposmia in 33 (7%), and cacosmia in 55 (11.7%). After 1 year, PIOD improved in 82 (79.6%) patients re-tested. Conclusion The current study demonstrated that persistent olfactory dysfunction is a relevant symptom in patients with AURI, even though many patients had normal olfactometry. Thus, smell impairment deserves careful attention and requires objective documentation. |
