Is corticosteroid treatment before surgery for chronic rhinosinusitis with nasal polyps recommended during the pandemic? And if so, intranasal or oral?
The use of intranasal corticosteroids does not seem to have a negative impact on symptoms and/or development of COVID-19.116Therefore, intranasal corticosteroid treatment should be continued perioperatively if possible. The use of corticosteroids either during an exacerbation or perioperatively should be carefully considered on a ‘per-patient’ basis. Recent guidance from the WHO has advised against the use of systemic corticosteroids if COVID-19 is suspected due to concerns that these agents may impair innate antiviral immune responses.125
