Allergic rhinitis, also known as allergic rhinitis, is an allergic disease of the nasal mucosa and can cause a variety of complications. Another type of allergic rhinitis is induced by non-specific stimuli, without specific allergens, and is not an immune reaction process, but the clinical manifestations are similar to the above two types of allergic rhinitis, called vasomotor rhinitis or neuroreflex rhinitis. However, because there is no antigen-antibody reaction in the body, desensitization therapy, hormone or immunotherapy are not effective. Etiology: Allergic rhinitis can occur at any age, in both men and women, and is easily seen in young people. Typical symptoms are nasal itching, continuous episodes of paroxysmal sneezing, large amounts of watery nasal discharge and nasal congestion. 1. Understand the causes of allergic rhinitis and avoid exposure as much as possible. (A) inhalation allergens: such as indoor and outdoor dust, dust mites, fungi, animal fur, feathers, cotton wool, etc., cause perennial attacks; plant pollen caused by the seasonal attacks. (B) food allergens: such as fish and shrimp, eggs, milk, flour, peanuts, soybeans, etc.. In particular, certain drugs, such as sulfonamides, quinine, antibiotics, etc. can cause the disease. (C) contact objects such as cosmetics, gasoline, paint, alcohol, etc. 2.If necessary, nasal secretion smear examination, allergic excitation test, etc. can be done. 3.Desensitization therapy. 4.Drug therapy: including 1. antihistamine drugs: these drugs include ketamine, etc., but the rest of the minerals are toxic to the heart, so use with caution. 2. sodium cromoglycate 3. ketotifen, 4. steroid hormone more local application, the better effect such as sodium Burke, Renocort, etc. 5. Local treatment can be used microwave, laser to reduce the sensitivity of nerve endings, partly effective. 6.Featured Chinese medicine treatment: for the root of the pathogen, evidence-based treatment, Chinese herbal medicine, acupuncture treatment, acupressure, acupoint injection and other treatments. 7.Minimally invasive surgical treatment: pterygoid canal neurectomy or superficial rock nerve cut and sieve anterior nerve cut to reduce the excitability of sympathetic nerves, the current treatment mainly adopts low-temperature plasma treatment under nasal endoscopic navigation, followed by nasal endoscopic navigation to correct structural rhinitis (such as nasal septal deviation correction, etc.).
