Suggestion: Adenoid hypertrophy is the hyperplasia of pharyngeal tonsils. Adenoid is hidden in the back of nasal cavity, which is the lymphatic tissue at the top of nasopharynx. Adenoid exists after birth and proliferates with age. It is the largest at about 6 years old, then gradually degenerates, and generally begins to shrink after 10 years old. Adenoid hypertrophy in children is mostly physiological, and it is called adenoid hypertrophy only if it affects the whole body health or adjacent organs. Generally, adenoid hypertrophy is right. However, if the child suffers from respiratory tract infection repeatedly, the adenoids will be pathologically proliferated due to repeated stimulation of inflammation, which can rapidly proliferate and hypertrophy, aggravate nasal obstruction, and hinder nasal drainage. Nasal secretions stimulate the adenoids to continue to proliferate, forming a vicious circle of mutual cause and effect, affecting the growth and development of the child. If the symptoms are not very serious, you can observe them for a period of time to prevent respiratory tract infection, and the adenoids may gradually shrink. Of course, this is the most ideal. At present, the best treatment for adenoidal hypertrophy is surgical resection, which has good postoperative effect. Generally, it can be operated when the child is over 4 years old. However, if the child has an "adenoid face", it will be difficult to recover, which is a great pity. As for whether to achieve the surgical guidelines, it is necessary to listen to the opinions of nasopharyngeal doctors.
