<!-- Definition and symptoms -->
'''Nasal polyps''' are [[benign tumor|noncancerous growths]] within the [[nose]] or [[paranasal sinus|sinuses]].<ref name=New2008/> Symptoms include trouble breathing through the nose, [[loss of smell]], decreased taste, [[post nasal drip]], and a [[runny nose]].<ref name=New2008/> The growths are [[Polyp (medicine)|sac-like]], movable, and nontender, though face pain may occasionally occur.<ref name=New2008/> They typically occur in both nostrils in those who are affected.<ref name=New2008/> Complications may include [[sinusitis]] and broadening of the nose.<ref name="Zit2018">{{Cite book |last=Yellon |first=Robert |title=Zitelli and Davis' Atlas of Pediatric Physical Diagnosis |publisher=Elsevier Health Sciences |year=2018 |isbn=978-0323079327 |pages=868–915}}</ref>

<!-- Cause and diagnosis -->
The exact cause is unclear.<ref name=New2008/> They may be related to chronic [[inflammation]] of the lining of the sinuses.<ref name=New2008/> They occur more commonly among people who have [[allergies]], [[cystic fibrosis]], [[aspirin sensitivity]], or certain infections.<ref name=New2008/> The polyp itself represents an overgrowth of the mucous membranes.<ref name=New2008/> Diagnosis may be accomplished by looking up the nose.<ref name=New2008/> A [[CT scan]] may be used to determine the number of polyps and help plan surgery.<ref name=New2008/>

<!-- Treatment and prognosis -->
Treatment is typically with [[corticosteroids|steroids]], often in the form of a [[nasal spray]].<ref name=New2008/> If this is not effective, [[surgery]] may be considered.<ref name=New2008/> The condition often recurs following surgery; thus, continued use of a steroid nasal spray is often recommended.<ref name=New2008/> [[Antihistamine]]s may help with symptoms but do not change the underlying disease.<ref name=New2008/> [[Antibiotics]] are not required for treatment unless an infection occurs.<ref name=New2008/>

<!-- Epidemiology -->
About 4% of people currently have nasal polyps while up to 40% of people develop them at some point in their life.<ref name=New2008/> They most often occur after the age of 20 and are more frequent in males than females.<ref name="New2008">{{Cite journal |last=Newton |first=JR |last2=Ah-See |first2=KW |date=April 2008 |title=A review of nasal polyposis. |journal=Therapeutics and Clinical Risk Management |volume=4 |issue=2 |pages=507–12 |doi=10.2147/tcrm.s2379 |pmc=2504067 |pmid=18728843 |doi-access=free}}</ref> Nasal polyps have been described since the time of the [[Ancient Egyptians]].<ref>{{Cite book |last=Önerci |first=T.
