'''Nasal polyps''' are [[polyp (medicine)|polypoidal]] masses arising mainly from the [[mucous membrane]]s of the [[nose]] and [[paranasal sinus]]es. They are overgrowths of the mucosa that frequently accompany [[allergic rhinitis]]. They are freely moveable and non-tender. Nasal polyps are usually classified into antrochoanal polyps and ethmoidal polyps. Antrochoanal polyps arise from the [[maxillary sinus]]es and are much less common, ethmoidal polyps arise from the [[ethmoidal sinus]]es. Antrochoanal polyps are usually single and unilateral whereas ethmoidal polyps are multiple and [[bilateral]]. Symptoms of polyps include nasal block, [[sinusitis]], [[anosmia]] (that is, loss of smell), and secondary [[infection]] leading to [[headache]].<ref>[http://www.emedicine.com/ped/topic1550.htm eMedicine - Nasal Polyps : Article by John E McClay, MD<!-- Bot generated title -->]</ref>
The pathogenesis of nasal polyps is unknown. Nasal polyps are most commonly thought to be caused by allergy and rarely by [[cystic fibrosis]] although a significant number are associated with non-allergic adult [[asthma]] or no respiratory or allergic trigger that can be demonstrated.
These polyps have no relationship with colonic or uterine polyps. Irregular unilateral polyps particularly associated with pain or bleeding will require urgent investigation as they may represent an intranasal tumour.
Nasal polyps are most often treated with steroids, topical or oral, but can also be treated with surgical methods.
Pre-post surgery, [[sinus rinses]] with a warm water (240 ml / 8 oz) mixed with a small amount (teaspoon) of [[salts]] ([[sodium chloride]] & [[sodium bicarbonate]]) can be very helpful to clear the [[Paranasal sinus|sinuses]]. This method can be also used as a preventative measure to discourage the polyps from growing back and should be used in combination with a nasal steroid.
[[Mometasone furoate]], commonly available as a nasal spray for treating common allergy symptoms, has been indicated in the [[United States]] by the [[Food and Drug Administration|FDA]] for the treatment of nasal polyps since December 2004.
