Unilateral polyps occasionally occur in association with or represent benign or malignant tumors of the nose or paranasal sinuses.

Symptoms include obstruction and postnasal drainage, congestion, sneezing, rhinorrhea, anosmia, hyposmia, facial pain, and ocular itching.
Diagnosis generally is based on physical examination. A developing polyp is teardrop-shaped; when mature, it resembles a peeled seedless grape.
Treatment of Nasal Polyps
Topical corticosteroid spray
Sometimes surgical removal
Corticosteroids (eg, mometasone [30 mcg/spray], beclomethasone [42 mcg/spray], flunisolide [25 mcg/spray] aerosols), given as 1 or 2 sprays 2 times a day in each nasal cavity, may shrink or eliminate polyps, as may a 1-week tapered course of oral corticosteroids. In patients with severe chronic rhinosinusitis with nasal polyps, biologics (eg, dupilumab) have been effective by shrinking the polyps and improving symptoms (1 Treatment reference Nasal polyps are fleshy outgrowths of the nasal mucosa that form at the site of dependent edema in the lamina propria of the mucous membrane, usually around the ostia of the maxillary sinuses... read more ).
Surgical removal of nasal polyps is required in many cases. Polyps that obstruct the airway or promote sinusitis are removed, as are unilateral polyps that may be obscuring benign or malignant tumors.
Polyps tend to recur unless the underlying allergy or infection is controlled. After removal of nasal polyps, topical beclomethasone or flunisolide therapy tends to retard recurrence. In severe recurrent cases, maxillary sinusotomy or ethmoidectomy may be indicated. These procedures are usually done endoscopically.
