Conservative treatment for nasal polyps is mainly applicable to cases with smaller range and less severe symptoms. Generally, it is advisable to begin with some nasal endoscopy to assess the extent of the condition. The primary treatment method considered is nasal sprays, particularly corticosteroid nasal sprays, and additionally, physiological saline can be used to cleanse the nasal cavity.

If accompanied by rhinitis and sinusitis, it may also be necessary to consider treatment with oral medication. Overall, most patients see some effectiveness with conservative treatment, but there may be recurrence or cases where conservative treatment is not effective, and surgery might be considered as an option.
