Snot in the nose

Introduction The nasal discharge that seems to be invisible in the nose is one of the symptoms of nasal polyps. Nasal polyps are common diseases in the nose. It is the result of tissue edema caused by a long-term inflammatory reaction of the nasal mucosa. Occurs in the outer side of the nasal cavity and the top of the nose. Nasal polyps are not true tumors and are often the result of allergic reactions and nasal mucosal edema caused by chronic inflammation of the sinuses. Its clinical manifestations are: patients have a long history of nasal disease. The initial nose seems to have a snot that can't be found. At night, there may be obvious nasal congestion and mouth breathing, and chronic pharyngitis may occur for a long time.

Cause

1. Chronic inflammatory infection: chronic inflammation induces nasal polyps, long-term stimulation of purulent secretions of chronic rhinitis and sinusitis, causing thrombophlebitis and lymphatic reflux disorder in the nasal mucosa, causing edema of the nasal mucosa and producing nasal polyps.

2, the incidence of nasal polyposis is related to a variety of factors, such as genetic factors, immunodeficiency, cilia dysfunction, aspirin intolerance, etc. These reasons are basically less common, but the medical community often thinks that it is caused by many reasons. .

3, allergic reaction: allergic reaction caused by nasal polyps, due to allergic reactions in the nose many times, under the action of histamine, leukotriene and other chemical mediators, nasal vascular permeability increased, plasma exudation increased, making The nasal mucosa is extremely edematous and gradually sags due to gravity, resulting in the formation of polyps.

If patients with nasal polyps do not take timely treatment, it will not only aggravate the symptoms of nasal polyps, but also cause many complications, so treatment is very important.

Nasal endoscopy

Examination of nasal polyps: One or more smooth, gray or reddish surfaces such as lychee meaty, translucent masses can be seen on the nose. The touch is soft, painless, removable, and generally less prone to bleeding. Because of its small size, early polyps can sometimes be found after contraction of the inferior turbinate. According to its shape, color and palpation, there is no difficulty in diagnosis.

Differential diagnosis

Intranasal pain: due to dryness and rupture of the nasal mucosa, may be associated with nosebleeds. Intranasal pain is also one of the symptoms of nasal cancer.

Herpes zoster ophthalmicus may be associated with orbital inflammation, conjunctivitis, keratitis, scleritis, uveitis, retinopathy (acute retinal necrosis), optic neuritis, ophthalmoplegia Wait. 60% of them can develop herpes zoster keratitis, which causes corneal scars and seriously affects vision. There has been a tendency to increase gradually in recent times and it is worthy of vigilance. The occurrence of keratitis occurs mostly after the appearance of rash, especially the presence of herpes zoster on the tip of the nose or the nose, which is a sign of invasion of the nasal ciliary nerve, followed by keratitis and iritis.

Itching in the nose: common in rhinitis. Rhinitis refers to inflammation of the nasal mucosa and submucosal tissue. It is characterized by congestion or edema. Patients often have nasal congestion, runny water, itchy nose, throat discomfort, and cough. The thin liquid substance secreted by the nasal cavity is called nasal discharge or nasal secretions. Its function is to help remove dust and bacteria to keep the lungs healthy. Usually, the bacteria and dust of the nose are mixed into the throat and eventually enter the stomach. Because of its small amount of secretion, it generally does not attract people's attention. When inflammation occurs in the nose, a large amount of nasal discharge can be secreted in the nasal cavity, and it can become yellow due to infection. When it passes through the throat, it can cause coughing. When the amount of nasal discharge is very large, it can also flow out through the anterior nares.

Runny nose: It is one of the common symptoms of nasal diseases. It can flow out through the anterior nares or into the nasopharynx. After flowing into the nostrils, the nasopharynx and the oral cavity are said to have a runny nose. There is only a small amount of mucus in the normal nasal cavity, which is in a wet state to maintain normal physiological functions. Changes in the nature and amount of nasal secretions can occur when there is a lesion in the nasal cavity. When the nasal secretions overflow, it is called a runny nose.
