Nasal polyps (NP) are noncancerous growths within the nose or sinuses.[1] Symptoms include trouble breathing through the nose, loss of smell, decreased taste, post nasal drip, and a runny nose.[1] The growths are sac-like, movable, and nontender, though face pain may occasionally occur.[1] They typically occur in both nostrils in those who are affected.[1] Complications may include sinusitis and broadening of the nose.[2]
The exact cause is unclear.[1] They may be related to chronic inflammation of the lining of the sinuses.[1] They occur more commonly among people who have allergies, cystic fibrosis, aspirin sensitivity, or certain infections.[1] The polyp itself represents an overgrowth of the mucous membranes.[1] Diagnosis may be accomplished by looking up the nose.[1] A CT scan may be used to determine the number of polyps and help plan surgery.[1]
Treatment is typically with steroids, often in the form of a nasal spray.[1] If this is not effective, surgery may be considered.[1] The condition often recurs following surgery; thus, continued use of a steroid nasal spray is often recommended.[1] Antihistamines may help with symptoms but do not change the underlying disease.[1] Antibiotics are not required for treatment unless an infection occurs.[1]
About 4% of people currently have nasal polyps while up to 40% of people develop them at some point in their life.[1] They most often occur after the age of 20 and are more frequent in males than females.[1] Nasal polyps have been described since the time of the Ancient Egyptians.[4]
