CT of the sinuses without contrast is the preferred imaging study for the diagnosis of nasal polyps. Coronal CT with 3- to 4-mm cuts and appropriate soft tissue and bone windows should be specified. Scan results should be reviewed with attention to the anterior ethmoid artery, orbital and skull base anomalies, optic nerve and carotid in posterior ethmoidal (Onodi) cells, and sphenoid sinus.

Biopsy is not always required for the diagnosis of nasal polyps. However, nasal masses without the classic appearance of bilateral nasal polyps such as unilateral masses or those that do not respond to conservative treatment should be examined with careful biopsy for diagnosis.

Relevant laboratory studies may include nasal smears or cultures for fungus and bacteria or allergy or asthma studies if indicated.
