Nasal polyps refer to benign space-occupying lesions in our nasal cavities. Clinically, nasal polyps are mainly associated with allergies or increased vascular and tissue permeability. Other factors, such as abnormalities in the structure of the middle nasal meatus, are also related to their formation. Therefore, in terms of treatment, clinically, we mainly use some steroids, mainly spraying corticosteroid hormones, such as mometasone furoate, budesonide nasal spray, fluticasone propionate nasal spray, etc. Additionally, if there is a significant amount of pus in the nasal discharge, we can also use saline nasal spray to clean the nasal cavity.
