Ask the Experts: An International Consensus on Managing Post-Infectious Olfactory Dysfunction Including COVID-19.

Purpose of Review: To summarise the current understanding of post-infectious olfactory dysfunction (PIOD) and provide a consensus on management of the condition through an evidence-based approach, critically reviewing the available management options.

Recent Findings: New studies investigating the pathophysiology of PIOD in COVID-19 patients have found that in those with persistent symptoms there is an association with lower tissue perfusion in the orbital and medial regions of the frontal lobe. Recent meta-analyses have listed olfactory training as the first line management for PIOD.

Summary: Olfactory training remains the most recommended management option for PIOD. The use of systemic corticosteroids to treat PIOD is not encouraged due to poor evidence.
