Effect of monoclonal antibodies on olfactory dysfunction caused by chronic rhinosinusitis with nasal polyps: a systematic review and meta-analysis.

This is the first meta-analysis presenting clinical outcomes with regard to olfactory function in CRSwNP patients who had been treated with monoclonal antibodies. The positive effect of biologic treatment on the olfactory function of these patients requires further study so that the sustainability of results and duration of treatment can be determined.
