Adenoid hypertrophy can be simply classified as physiological or pathological, and only pathological adenoid hypertrophy requires medical attention. The choice of treatment depends on the severity of the disease and the presence or absence of comorbidities. In summary, the clinical manifestations of adenoid hypertrophy are: 1. Nasal symptoms: nasal congestion, runny nose, occlusive nasal sound, sleep snoring or with breath-holding. 2. 2.Ear symptoms: ear congestion, hearing loss and tinnitus. 3.Other respiratory symptoms: paroxysmal cough, coughing sputum, etc. 4.Facial changes: deformation of hard palate, high arch, thickening and lifting of upper lip, uneven teeth, protruding upper incisors, widening of eye spacing and lack of expression, which is called “adenoid face”. 5. Systemic symptoms: short stature, emaciation, night terrors, teeth grinding, urination, slow reaction, inattention, etc. There may also be chest tightness, shortness of breath, palpitations and other manifestations of pulmonary heart disease. Adenoid hypertrophy, like most other diseases, follows a stage-by-stage pattern of development from mild to severe, and the goal of clinical work is to intervene appropriately in the early stages of the disease to prevent it from developing into a severe segment. It is not easy to do this! Due to the parents of the children (who feel that the children are young), the children often visit pediatrics (usually most of them visit pediatric internal medicine and come to otorhinolaryngology only after several treatments have failed), and the fact that they are now only children. Many children come for examination almost always with surgical pointers now. Early detection (family mission), early diagnosis and early treatment (hospital mission) are crucial. In fact, most parents who seek medical attention are more concerned about the need for surgery for adenoid hypertrophy, while doctors weigh the pros and cons of surgery. Here we can divide it into the following two cases in layman’s terms: 1. must be opened: adenoid hypertrophy continues to snore seriously, with breath-holding and oxygen deprivation, which may or has affected the child’s growth and intellectual level; the pharyngeal tube is pressurized, and the continuous tympanic fluid accumulation cannot be eliminated, affecting the child’s hearing, etc. 2.Can be opened or not: Adenoid hypertrophy is intermittent snoring, sometimes light and sometimes heavy, sometimes with breath-holding, occasionally affecting the child’s rest and sleep; the eustachian tube is not under pressure, but the tympanic fluid is easy to repeat, sometimes affecting the child’s hearing. 3, can be conservative treatment: adenoid hypertrophy without snoring, no breath-holding, no sleep open-mouth breathing, only slight snoring after cold; pharyngeal tube is not under pressure, occasionally a history of otitis media, no impact on hearing. The more difficult trade-off is the second case, and children with this condition may be considered for treatment and observation first, depending on their developmental changes. Although the age limit for adenoids surgery in children has been relaxed, it is still appropriate to operate on children over the age of 4 years, except in rare cases. The traditional surgical methods include adenoid scraping, nasal endoscopic adenoid power system cutting, and nasal endoscopic plasma ablation cutting. The advantages of this method are: the whole adenoids are clearly visible and cleanly removed; skilled otorhinolaryngologists can achieve the realm of no bleeding with plasma cutting of adenoids; little postoperative pain and quick recovery.
