Olfactory training outcomes in post COVID 19 olfactory dysfunction

Objectives: The aim of study is to evaluate the olfaction recovery of patients who performed OT (olfactory training) in a post-COVID-19 PPVOD. Methods: Study included 50 patients with a sudden loss of smell and a confirmed COVID-19 diagnosis from January 2020 to January 2021 in Kirkuk General Hospital. These participants were submitted to The Sniffin’ Sticks test in order to identify those with persistent olfactory dysfunction who were treated either by olfactory training combined with a 10-day course of oral corticosteroids, or by olfactory training alone. Results: Cross sectional comparative study for 50 patients have history of COVID 19 infection, mean age of patients [47 ± 10] years. [56%] of patients at age group ≥ 45 years, [44%] of patients are females and [56%] are males. The mean of TDI score increase after OT than before OT with significant difference. Conclusion: Olfactory function appeared to improve only in peripheral aspects of post COVID-19 PPVOD after OT. patients < 45 years have high mean of TDI score than patients ≥ 45 years old.
