1, acute rhinitis: acute infection, commonly known as “wind” or “cold”, may have systemic symptoms; to autumn and winter or winter and spring turn more common. The disease generally improves gradually after 7 to 14 days. Those with strong resistance can be cured without treatment. Acute inflammation of the mucous membrane of the nasal cavity is common and is a viral infection, often followed by bacterial infection. The main symptoms are nasal blockage and increased secretion, early clear watery snot, later becoming mucopurulent nasal snot, the patient may have low fever and general discomfort. On examination, the nasal mucosa is congested and swollen with secretions. This disease should be prevention-oriented, after the disease to take antipyretic drugs, intranasal drops of 1% ephedrine solution, if necessary, sulfa drugs or antibiotics. 2. Chronic rhinitis: It is a common and frequent disease, which develops from acute rhinitis. Associated with combined bacterial secondary infections, incomplete treatment and recurrent episodes. It is a chronic inflammation of the mucosa and submucosa of the nasal cavity. It is very common and is called simple chronic rhinitis in mild cases and hypertrophic rhinitis in severe cases. The main symptom is nasal blockage, intermittent or alternating in mild cases or persistent in severe cases, with increased nasal discharge. In severe hypertrophic rhinitis, due to tissue hyperplasia, the mucosal surface is uneven, the inferior turbinates show mulberry-like changes, and the mucosa of the middle turbinates shows polypoid changes. Intranasal drops of vasoconstrictors, such as 1% ephedrine, can improve the ventilation and drainage of the nasal cavity and make the inflammation subside. In severe cases, sclerosing agents can be injected under the mucosa of the inferior turbinate, and electrocautery or cryotherapy can also be used to improve ventilation, and in severe cases, the enlarged part of the turbinate needs to be surgically removed. Chinese medicine and acupuncture treatment have certain effect on patients with mild disease. 3, chronic hypertrophic rhinitis: from chronic simple rhinitis, is a long-term chronic inflammation, bruising and nasal mucosa, nasal turbinates appear hyperplasia. At this time, the mucous membrane thickening, tissue elasticity decreased, poor nasal ventilation, thus endangering the physiological function of the nose. 4, dry rhinitis: the occurrence of dry rhinitis and climate and occupational factors have a close relationship. The nasal mucosa is irritated for a long time and the mucus glands atrophy, secretion reduction caused by the mucosa and thus dry and even superficial erosion. 5, atrophic rhinitis: mainly nasal mucosa, periosteum and turbinate bone atrophy; due to atrophy of nasal tissue, although the nasal cavity is relatively wide, but the nasal mucosa lost its normal physiological function, and because of the formation of dry nasal demented, patients still feel poor ventilation. When there is bacterial infection, its toxins and excreta produce foul odor. There are two kinds of primary and secondary cases. In primary cases, the cause is unknown and there is atrophy of the mucosa and bone of the turbinates. The patient has nasal congestion, a foul odor in the nose, and pus crusts. On examination, the nasal mucosa is dry and atrophied, and the inferior turbinate is shrunken, resulting in a wide nasal cavity, and due to bacterial infection, there is a large amount of gray-green dirty crust in the nose, and there is a foul smell, so it is also called odoriferous nose. Severe cases can be followed by atrophic pharyngitis and laryngitis. There is no specific treatment for this disease, the nasal cavity is rinsed with saline to remove the scabs, liquid paraffin, compound peppermint oil, compound cod liver oil combination, etc. can reduce the symptoms, children patients oral or intramuscular injection of vitamin A. Surgical treatment such as reduction of nasal cavity has been used to treat this disease, its effect is limited. The secondary cases include excessive removal of turbinates during surgery, after radiation therapy for malignant tumors of the nose, sinuses and nasopharynx, long-term exposure to irritating dust or chemical gases, etc. 6.Caseous rhinitis: It is a rare nasal disease. Clinical features are the accumulation of cheese-like material in the nose, with a foul odor, erosion of soft tissue and bone over time, the occurrence of internal and external nasal deformities. Among the cheese-like material are found exfoliated epithelium, necrotic tissue, septic cells, cholesterol crystals and mycobacterial-like microorganisms. 7, drug rhinitis: drug rhinitis is the result of inappropriate nasal medication long-term sustained action, can also be understood as a chronic rhinitis. The cause of the disease is inappropriate nasal medication, including the use of strong nasal mucosal vasoconstrictor nasal drops, excessive concentration of the solution, non-isotonic solution, overdose or long-term use of drugs. All these can damage the structure of nasal mucosal cilia, thus affecting the physiological function of nasal mucosa and producing clinical disease.
