There is no optimal age for having surgery for enlarged adenoids. Physiologic adenoid hypertrophy gradually regresses after the age of 6 years, and usually requires no special treatment; if the symptoms are more severe and accompanied by sleep apnea, early surgery is advisable. Adenoid hypertrophy is usually due to various inflammatory stimuli, metabolic reactions, and active lymphatic tissue proliferation. Adenoid hypertrophy in toddlers and children is usually due to the proliferation of lymphoid tissues in the nasopharynx, which can gradually deteriorate with age, and usually reaches its maximum extent around the age of 6 years. When children do not experience significant discomfort, such as apnea, surgical treatment is not necessary and close observation is sufficient. If children develop adenoid hypertrophy, accompanied by multiple episodes of apnea, chest tightness and restlessness, and generalized malnutrition, they need prompt surgical treatment, and there is no such thing as continuing to wait for the optimal age for surgery. Adenoid hypertrophy can choose general anesthesia under the nasal endoscopic resection, plasma radiofrequency ablation. The severity of adenoid hypertrophy varies, so parents are advised to bring their children to the doctor in time and choose the appropriate treatment plan based on the doctor’s recommendation.
