Summary

SARS COV-19 has resulted in prolonged olfactory dysfunction in many patients. The investigators aim to compare the effect of topical platelet-rich plasma (test) vs saline (placebo) in patients with covid-related post-viral olfactory dysfunction.

Detailed description

The investigators hypothesize that the use of topical PRP will improve smell identification, threshold, and smell-related quality of life in comparison to a placebo. This study will provide critical information for a promising new treatment of olfactory dysfunction with the highest level of evidence, in a randomized, placebo-controlled trial. Preliminary results from an ongoing pilot study investigating topical PRP is the basis for the hypothesis. By investigating the efficacy of topical PRP in smell restoration, the investigators will provide a less-invasive way to deliver this autologous product. A randomized trial will set a precedent for the use of this treatment to serve a growing population of patients affected with post-COVID olfactory dysfunction. Over a period of one year, participants with post-viral olfactory dysfunction will be randomly assigned to a test or control group and will visit the clinic monthly for three months to receive PRP or saline based on their randomized group. This will be followed by 9 months of at-home electronic visits. At each visit both the test and control groups will undergo smell testing and will fill quality of life questionnaire.
