Nasal Polyps
It is a special form of sinusitis (called "polypoid sinusitis"). Nasal polyps are masses of inflamed tissue-like sacs that line the nose (nasal mucosa) or sinuses.
Nasal polyps typically start near the ethmoid sinuses, located at the top of the inside of the nose, and grow into the open areas.
Large polyps may block the sinuses or nasal airway.
People with the following conditions are also more likely to develop nasal polyps:
- Sensitivity to aspirin (wheezing)
- asthma
- Chronic sinus infections
- cystic fibrosis
- Hay fever (allergic rhinitis)
The studies that are usually done to detect the presence of polyps are:
- Computed tomography: evidence for the occupation of the nose and sinuses.
- Larynx exam: polyps can be observed directly with fiber optics in the audiologist's office.
The reason that causes the appearance of polyps in the nose is unknown. It can occur at any age and both sexes. Previously it was thought that allergy was the cause of the appearance of polyps. However, many patients with polyposis have no allergy and, conversely, most patients are not allergic nasal polyposis.
A special group of patients with nasal polyposis have or have had bronchospasm. In other cases the trigger for the onset of polyps is a specific intolerance to aspirin.
These are the main characteristics of Nasal polyps:
- They are the result of a proliferation of benign oedematous lining of the nostrils
- Its origin is inflammatory
- Are rounded, they are soft, smooth, translucent, grayish-pink
- They are located mainly in the lateral wall of the nostrils in the middle meatus or the middle and upper commit.
- Large polyps can lead to obstruct the airway.
