The growing number of COVID-19 patients with long-lasting olfactory disorders makes it necessary to identify ef- fective treatments that enhance the spontaneous recovery of olfactory function.

Multicentre randomised case-control study that involved 18 patients with COVID-19 related anosmia or severe hyposmia for more than 30 days.

Nine patients were prescribed systemic prednisone and nasal irrigation with betamethasone, ambroxol and rinazine for 15 days.

The other 9, untreated, patients were used as controls. The olfactory function was evaluated with CCCRC test at 20 and 40 days from the first evaluation.
