Nasal polyps can be treated with antihistamines and decongestants, if the condition is mild, or a nasal corticosteroid spray, according to WebMD. A tapered course treatment of oral corticosteroids may be necessary to reduce the irritation and swelling caused by nasal polyps.
When nasal polyps are obstructive or too large for steroid treatments to provide relief, an endoscopic surgical treatment may be necessary to remove the nasal polyps while preserving normal tissue, explains WebMD. Surgery to remove nasal polyps is typically performed on an outpatient basis.
During endoscopic surgery, a small tube with a lens or camera is inserted into the nostrils and guided into the sinus cavities, according to Mayo Clinic. Surgeons use small instruments to remove obstructions and nasal polyps that contribute to a blocked flow of fluid from the sinuses. In some cases, surgeons may widen the openings that lead from the sinuses to the nasal passages.
Nasal polyps are teardrop-shaped growths that can form in the sinuses or nose, typically where the sinuses open into the nasal cavity, according to WebMD. The growths are noncancerous and do not cause symptoms. Small nasal polyps may not require treatment, but larger nasal drops, especially when blocking drainage from the sinuses, require treatment to avoid infections in the sinuses or nose due to mucus accumulation.
