Expert answer: Condition analysis: Hello, allergic rhinitis is a type of rhinitis. Rhinitis also includes chronic rhinitis and acute rhinitis, the latter usually refers to a cold. Chronic rhinitis includes simple rhinitis with mild symptoms and hypertrophic rhinitis with obvious nasal congestion. Both types of chronic rhinitis can reduce symptoms through different treatments. Guidance: Recommendation: rhinitis tablets, plus sinusitis oral solution, and erythromycin ointment on the nose at night, the effect is good. The hospital diagnosis and treatment center has launched an online registration and appointment system. After successful registration on the website, the expert registration fee can be reduced or discounted, and there are discounts. It is more convenient and faster to make an appointment to see a doctor, saving you the trouble of queuing up to see a specialist. Let’s learn about the symptoms of allergic rhinitis: 1. Nasal congestion: varying degrees, unilateral or bilateral, intermittent or persistent, or alternating. 2. Nasal itching and continuous sneezing: paroxysmal attacks often occur several times a day, followed by nasal congestion and runny nose, especially in the morning and at night. Nasal itching is seen in most patients, and sometimes itching occurs outside the nose, soft palate, face, and external auditory canal. Seasonal rhinitis is more obvious with eye itching. 3. Olfactory disorder: If it is caused by mucosal edema or nasal congestion, it is mostly temporary. It is mostly caused by olfactory nerve atrophy caused by persistent mucosal edema. 4. A large amount of watery nasal discharge: When the acute reaction tends to weaken or disappear, it may reduce or become thicker. If secondary infection occurs, it may turn into mucopurulent secretions. Causes of allergic rhinitis: 1. Food allergens: such as fish and shrimp, especially certain drugs. 2. Allergic constitution caused by genetic factors: Not everyone will suffer from allergic rhinitis, and it generally occurs in people with allergic constitution. Allergic constitutions are related to genes and are usually caused by inheritance. Most patients with allergic rhinitis have a family history of allergies. However, in recent years, due to the acceleration of industrialization and the intensification of air pollution, some people who were originally non-allergic have developed allergic constitutions. 3. Contact allergens: The most important allergens in the home are dust mites, mold, pets and insects. There are more dust mites and their excrement on bedding and underwear that are in close contact with the human body; indoor molds tend to grow in humid, warm, and poorly ventilated environments; a variety of insects, including crickets, flies, and moths, especially Cockroach excrement contains certain allergens. Outdoor allergens can be present in spring, summer, fall and winter. Including: camphor, walnut trees, hazelnut trees, juniper trees, poplar trees, birch trees and oak trees. 4. With the increase in vehicles in recent years, aromatic hydrocarbon particles in diesel exhaust gas and formaldehyde caused by home decoration, etc., although they are not allergens, are strong irritants for seasonal allergic rhinitis attacks. 5. Other possible causes: Certain bacteria and their toxins, physical factors (such as hot and cold changes, temperature irregularities), endocrine disorders or acid-base balance disorders of body fluids can all cause the disease. It can also be due to multiple factors existing at the same time or one after another. Combined preethmoidal nerve blockage is a professional treatment for allergic rhinitis. This technology is a new example of the successful application of physical science to medical treatment of allergic rhinitis. It is the crystallization of human wisdom and one of the most effective treatment methods in the world. It was recognized by industry insiders in 2011. It is called a major breakthrough in clinical application technology of otolaryngology in China. At present, the clinical application of combined preethmoidal nerve blockade in the Department of Otolaryngology of Jiashi Hengxin Hospital has been very mature, bringing new hope to the majority of patients! Combined preethmoidal nerve blockade to treat allergic rhinitis is a brand-new non-invasive technology and another innovation of focused ultrasound non-invasive treatment technology in the field of non-tumor disease treatment. It has completely broken away from the traditional concept of invasive surgery. .
