Nasal Polyp

Nose disease

A nasal polyp (NP) is a soft, fleshy swelling that grows inside the nose. It may be yellowish, gray or pink in color. Nasal polyps are found in varying degrees. Sometimes it is only one, but they can also be like a ‘small bunch of grapes’ growing on a stem. They are common. A nasal polyp is almost always benign, but nasty.


Cause

In most cases, the cause is not known. It is thought that a sustained (chronic) inflammation in the nose causes the excess growth of the lining of the nostrils. This can sometimes lead to the development of small polyps. These slowly grow bigger then. Polyps usually affect both nostrils. The cause of the inflammation is often unclear. Certain circumstances stimulate nose inflammation and polyps, including asthma, allergy to aspirin, cystic fibrosis and some rare nose conditions.


Symptoms

The size of nasal polyps can vary greatly. Normally they are the size of small water droplets, but in rare cases they can also grow to the size of small grapes. Nasal polyps can have the following signs and symptoms:


Diagnosis

To make the diagnosis, a doctor will check, with the aid of a special instrument, whether there are indeed polyps in the nose. If necessary, the patient will be referred to the ear, nose and throat (ENT) specialist, who can better examine the patient by means of nasal endoscopy under local anesthesia. Depending on the symptoms and severity, treatment can be started then.


Treatment

As a treatment for nasal polyps, nasal drops, nasal spray or possibly short-term tablets including corticosteroids are usually prescribed. These shrink the nasal polyps, reducing the symptoms.

If this doesn’t help, an ENT specialist can remove nasal polyps by surgery. During polyp extraction, the visible part of the nasal polyp is removed under local anesthesia. The part that resides in the cavity cannot be removed by this operation. This may be done by endoscopic sinus surgery. The removed tissue can then be examined, to exclude the possibility that it’s a malignant nasal polyp.


Prognosis

After polyp extraction, there is a high probability that the nasal polyp returns. Removing the complete lining of the affected sinus as well, in addition to the polyp, can help to prevent recurrence. Usually, long-term corticosteroid-containing nasal spray is given after the surgery, possibly allowing nasal polyps to be back less quickly.
