Phantosmia May Predict Long-Term Measurable Olfactory Dysfunction After COVID-19.

ABSTRACT:

Objectives

Persistent olfactory dysfunction (OD) after 6 months caused by SARS-CoV-2 infection has been reported with a variable prevalence worldwide. This study aimed to determine the prevalence of long-term OD and identify predisposing factors.

Methods

A prospective cohort study was conducted on 100 adults with COVID-19. Olfactory function was assessed with the University of Pennsylvania Smell Identification Test and a symptom survey at the onset of disease and 30 days later. Patients with persistent quantitative OD at the second assessment were reevaluated after 1 year. Demographic variables, symptoms, and the degree of smell loss were analyzed.

Results

Participants included 100 patients. The mean age was 42.2 ± 15.6 years, 55 (55%) were female, and 56 (56%) were o
