Under what circumstances do tonsils need to be removed surgically? For many parents and friends, this is a rather nagging question, especially concerned about whether the surgery will affect resistance, whether there are any after-effects, whether they have to be removed, etc. Tonsils are enlarged at an early age and reach their peak at the age of 6-8 years, and they gradually shrink in size as they get older. However, many children will have to have their tonsils removed due to inflammation or hypertrophy or some other problem that occurs before they shrink. Generally speaking, there are indications for surgical removal of tonsils, such as: 1) recurrent inflammation of tonsils, such as 2 years in a row, with more than 3-5 infections per year; 2) enlarged tonsils, which affect swallowing or breathing, such as long-term open-mouth breathing and snoring during sleep; 3) tonsillitis, which may be associated with nephritis, arthritis, heart valve lesions, etc. Surgical removal is mostly considered from the above aspects, weighing the surgery and the benefits before making a decision.
