“Nasal polyps” are inflammatory tissues formed when edematous mucosa protrudes into the nasal cavity from the nasal passages and sinuses. They can be manifested either as single polyps or as extensive so-called nasal polyposis, which can be seen as single or multiple lychee-like translucent swellings with smooth surfaces inside the nasal cavity when examined by rhinoscopy. 1, long history of disease Patients have a long history of nasal disease when they come to the clinic. The initial feeling is that there seems to be “unblowable snot” in the nose, which is caused by the blockage of the upper part of the nasal cavity by the polyp, and obvious nasal congestion at night, often with open-mouth whistling, which can be followed by chronic pharyngitis. 2, persistent nasal congestion is mostly persistent, vasoconstrictor drops have no obvious effect, this is the polyp rarely have blood vessel distribution. And because the polyp has no nerve distribution, so there is rarely sneezing. Nasal polyps patients’ nasal mucus is mostly viscous secretion, if there is secondary infection, there can be yellow, green purulent secretion. Continue to grow larger nasal polyps not only make nasal congestion significantly worse, and can cause dizziness or headache, which may be the cause of sinus involvement. 3, no sense of smell Nasal polyps patients have a sense of smell to loss of smell. Huge polyps, if the obstruction of the posterior nostril or even protruding into the nasopharynx, can also cause hearing loss and other ear symptoms, is the pharyngeal tube pharynx is compressed. A small number of huge nasal polyps can also cause erosive complications, the consequences of which are more serious, can make the external nose deformation, called frog-shaped nose.
