Nasal polyps are a fairly rare condition that occurs in approximately one to four percent of adults. They are benign growths that appear on the mucosal lining of the nasal passages and are teardrop in shape. Nasal polyps are most often seen in the opening into a sinus. Polyps most often occur in those who experience chronic sinusitis, have asthma, and/or endure frequent nasal and sinus allergies. There is a slightly higher incidence in males than compared to females. These types of polyps are very rare in children but are sometimes seen in those that have been diagnosed with cystic fibrosis. Some common symptoms of nasal polyps are a runny nose, congestion, decreased sense of smell or taste, headaches, and itching around the eyes. These polyps can sometimes cause breathing difficulties depending on their size and origin. It is unknown why and how nasal polyps actually appear but they are thought to be influenced by many different factors such as allergies, family history, and age to name a few. It is thought that nasal polyps are caused when normal nasal and sinus mucosa swell and fill up with fluid. Others believe polyps are their own entity. There are a few different ways of testing for nasal polyps. One way is to have a nasal endoscopy performed. For this exam a doctor will place a scope, or small camera, up into the nostril into the nasal cavity and literally look for the polyps. Other ways include allergy tests, CT scans, and Cystic Fibrosis tests. Treatment often involves trying to shrink the polyp or completely get rid of it. Corticosteroids are often used to try and reduce the size of the polyp or polyps. Either a polypectomy or endoscopic surgery on the sinuses can be performed in order to remove the polyp from the nasal passage. The type of surgery depends on the size and amount of the polyps. Some of the best ways to reduce ones chances of having polyps is by using a nasal rinse or a nasal lavage of saline, managing ones allergies and asthma, practicing good hand hygiene and humidifying ones home.
