Pediatric tonsillar hypertrophy can be caused by a variety of reasons, which may be physiological or due to inflammation. Therefore, their recovery time varies greatly and cannot be generalized. The tonsils are part of the body’s immune system and have the immune function of defending and resisting the invasion of external pathogens into the body. After the age of 14-15, when children reach puberty, the tonsils will gradually shrink as the immune system is gradually improved. In addition, some children’s tonsillar hypertrophy can be caused by inflammation and is usually cured clinically after 1 week of treatment. However, if a child has recurrent tonsillitis, throat discomfort, swallowing and respiratory function, it is recommended to visit the ENT department of a hospital in time for surgical removal under the guidance of a doctor.
