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. 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.
