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