The most common reasons for visiting ENT clinics include: fever, nasal congestion, sore throat, earache, and snoring; the cause is often recurrent tonsillar infections or adenoid hypertrophy that leads to the above symptoms, and the doctor usually recommends surgery to remove the tonsils and adenoids. Parents are often anxious and have difficulty making up their minds to undergo surgery. The biggest concerns include the effect of general anesthesia on the young child’s brain, the trauma of surgery and bleeding, and whether the removal of the tonsils as an immune organ will affect the child’s immune function. For mild to moderate infections of the tonsils and adenoids, surgery is not recommended if the symptoms can be effectively controlled with the use of sensitive antibiotics (usually 7-10 days); however, in cases where the symptoms do not improve with conservative treatment, surgery should be chosen early. The most common indications for tonsil adenoidectomy in children include (1) Severe and recurrent tonsillar infections, usually with high fever and sore throat symptoms, and more than 4-5 episodes per year, that warrant removal. (2) Severe tonsillar hypertrophy affecting breathing, swallowing or pronunciation. When combined with adenoid hypertrophy, the effect on breathing is especially obvious, with symptoms of nasal congestion and sleep snoring, children often need to open their mouths to breathe, and then a series of effects will occur. (3) Combined with sinusitis (3) In cases of combined sinusitis or secretory otitis media where long-term conservative treatment is not effective, surgical removal of the tonsils and adenoids can often quickly cure sinusitis and eliminate middle ear tympanic fluid. Therefore, for children with recurrent tonsillar infections that are difficult to control with conservative treatment and children with open-mouth breathing and sleep snoring, timely surgery can significantly benefit the child. Postoperative effects on the immune function of children have also not been found. Therefore, if your child has recurrent tonsillar infections that are difficult to control with medication or has open-mouth breathing and sleep snoring for more than 2 months due to tonsillar adenoid hypertrophy, choose surgery early.
