With the onset of autumn and the high incidence of allergic rhinitis, many patients continue to inquire about the diagnosis and treatment of allergic rhinitis. We are enclosing the core contents of Chinese Otolaryngology Head and Neck Surgery on the diagnosis and treatment of allergic rhinitis and hope to be of help. Early treatment, that is, starting treatment now, is recommended. Treatment with second-generation antihistamines and/or nasal glucocorticoids (e.g., budesonide nasal spray, etc.) is recommended until autumn passes, with higher doses recommended for perennial allergic rhinitis. Surgical treatment is generally not recommended. If asthma is present, it should be treated together with the lungs. I. Diagnosis 1. History: Take a detailed medical history, analyze the time of symptom onset and triggering factors, the presence or absence of asthma, and assess the severity of symptoms. At least three of the four symptoms of nasal itching, sneezing, nasal discharge and nasal congestion are present, and in perennial cases, the symptoms accumulate for more than 0.5 to 1 h daily during the symptomatic days. 2. Examination: Nasal examination reveals pale, edematous or congested, swollen nasal mucosa. Patients with hay fever often have obvious conjunctival congestion, edema, and swollen eyelids in severe cases. Eosinophil smear of nasal secretions and/or conjunctival scrapings are positive during the onset of the disease. Positive skin test for allergens, at least 1 (++) or more (+++). If available, serum or nasal secretion-specific IgE tests are available. If necessary, perform allergen nasal mucosal excitation test. Avoid contact with allergens: No matter what kind of treatment is used, we must try to avoid contact with allergens, although it is impossible to avoid it completely, but it is a necessary part of the treatment strategy. For the best treatment method. Such as going south to the local fall past and back. 2, drug therapy: in recent years, because of the efficient, long-lasting, safe drugs continue to come out, so that drug therapy in the treatment of allergic rhinitis occupies an important position. 3, immunotherapy: standardized allergen vaccine or dip should be selected for specific immunotherapy, adherence to treatment for 3-5 years is usually effective. Immunotherapy should be carried out. 4.Some immunomodulators and surgical treatment (partial inferior turbinatectomy) can have certain efficacy. 5.Other therapies: Randomized controlled clinical trials are needed to objectively assess their efficacy.
