What this Trial Is About

This research aims to evaluate the effects of olfactory training on persistent smell problems following COVID-19 infection. The study focuses on comparing the outcomes of two different sets of odors used in olfactory training over a 12-week period. Researchers will assess changes in smell function and related symptoms such as parosmia and phantosmia using various smell tests and questionnaires. Participants are randomly assigned to one of two groups: one group will smell four scents (rose, orange, clove, eucalyptus) twice daily for five minutes each session, and the other group will use a different set of four scents (cheese, coffee, strawberries, lemon) with the same schedule. The training lasts for 12 weeks. Initial and final meetings include detailed smell evaluations and questionnaires, with participants receiving instructions and a training kit at the start. During the study, participants will undergo smell tests including the UPSIT and Sniffin' Sticks, and complete questionnaires on the impact of smell dysfunction on quality of life. Researchers will also assess nasal obstruction and record symptoms of parosmia and phantosmia. Measurements are taken before and after the 12-week training. The total involvement includes an initial session, 12 weeks of home training, and a final evaluation session.
