Children with low immunity can easily contract some physical diseases, and adenoid hypertrophy is one of them. It compresses the child’s throat and other parts of the body, causing difficulty in breathing and causing the child to breathe through his or her mouth frequently, thus changing the face and causing other diseases in serious cases. Treatment can be mainly through medication, surgery, oral treatment. 1.Medication. Nasal cleansing by drops in rhinology can effectively relieve the problem of breathlessness. In addition, nasal spray is also a common medicine used by parents, and this treatment method is very useful for mild patients with few side effects. 2.Surgical treatment. The disadvantage of medication is that it is easy to have recurrent attacks. For patients who want to cure the problem, surgery may be better. Now this surgery is a minimally invasive type, the bleeding is reduced, in the post-operative although there is a certain chance of recurrence but not much, as long as good post-operative maintenance can be. 3. Oral treatment. Some children do not get timely treatment, resulting in some oral problems, such as malocclusion, etc., which requires an oral surgeon to treat.
