Recently, we found that parents have the most questions about adenoid hypertrophy, but there are nearly 100 patients in one day, so we don’t have time to answer them all carefully, so we used our break time to summarize the most frequently asked questions, and hope they will be helpful to parents. 1.What is adenoids? A: Adenoids, also known as pharyngeal tonsils, are present in all people, with physiological proliferation in childhood, enlargement to the maximum at the age of about 6, gradual atrophy at the age of 10, and complete atrophy in adults. But there are some children, repeated inflammatory stimulation (recurrent episodes of epiglottis, etc.) prone to pathological hyperplasia, that is, adenoid hypertrophy. Guang 2, why adenoid hypertrophy? (1) Long-term sleep disturbance and restricted ventilation can lead to chronic cerebral ischemia and hypoxia symptoms and adenoid face, irritability, poor temperament, slower growth and development than children of the same age, daytime dizziness, poor reflection and memory loss, etc. (2) Sinusitis recurrent: adenoid hypertrophy and rhinitis sinusitis as a result of each other, a vicious circle. The actual nasal sinusitis is easy to stimulate adenoid hyperplasia, while adenoids block nasal snot is not easy to discharge, nasal snot accumulation will aggravate the nasal sinusitis, nasal own defense is reduced, nasal sinusitis recurrent attacks. （The adenoids are close to the pharyngeal canal, which is a tube connecting the middle ear and the nasopharynx. The normal pharyngeal canal can discharge secretions from the middle ear into the pharynx. 3. How is adenoid hypertrophy treated? Initial adenoid hypertrophy can be controlled or not further enlarged by timely control of nasal inflammation and reduction of nasal irritation. For children with long-term adenoid hypertrophy and children with adenoid hypertrophy without standard treatment, they can be observed after 3 months of conservative treatment, and some of them can have their symptoms controlled without surgical treatment, while some of them need surgical removal if they are not sensitive to medication. Adenoid hypertrophy is often combined with tonsillar hypertrophy, usually need to be removed at the same time. 4.How big are the adenoids that need to be removed? In principle, 2/3 or more of the posterior nostril is already an indication for surgical removal, but not all adenoids need to be removed as long as they reach 2/3. It is also possible to see children with adenoids of more than 2/3, but they are not hypoxic or only slightly hypoxic, so they can be treated conservatively. 5.What do children with adenoid hypertrophy need to pay attention to in general? (1) Active treatment of cold, rhinitis, sinusitis and allergic rhinitis; (2) Enhance immunity to reduce the number of episodes of upper sensation; (3) More exercise to increase lung capacity, which can increase blood oxygen reserve to enhance the ability to resist hypoxia.
