Whenever your nose runs, a cold snatches the next one, and or your child snores in recent years, polyps may be behind it. But not only in childhood, the mucosal tumors cause annoying symptoms. Polyps are mucosal prominences, which usually sit on a stalk. They can occur in a variety of places in the body, which are covered with mucous membrane, for example in the gastrointestinal tract, bladder, teeth or sinuses.
Polyps in the nose
The polyp usually means the benign growth of the nasal mucosa, which lines the nose and paranasal sinuses from the inside, or - especially in children - the enlargement of the tonsils. Polyps are benign tumors, consist of connective tissue and contain fluid. Most nasal polyps are stalk-shaped or drop-shaped, more rarely they sit flat on the mucous membrane. They can be a few millimeters in size, but sometimes they expand so much that they close the entire nasal cavity.
Often they grow near the entrances to the maxillary sinuses, in the paranasal sinuses or in the connecting canals between sinuses and nasal cavity. As a rule, they develop on both sides. A one-sided occurrence can be an indication of a tumor disease - whether the polyp is benign or malignant, must then be clarified. Nasal polyps are very common and can occur at any age.
Causes of polyps
The most important cause of nasal polyps is chronic inflammation of the nasal mucosa. These can be caused for example by viruses, bacteria or fungi. Even with allergies and asthma or bronchitis, the nasal mucosa can change polyposis.
Once a mucosal inflammation becomes chronic, there is a risk that develop polyps and create a vicious circle: By the growths, the ventilation of the nose is difficult, which then favors further inflammation, which in turn lead to polyps. Nasal polyps are also a typical concomitant of cystic fibrosis, and people who are susceptible to aspirin often develop polyps.
