The lymphatic tissues of the human pharynx, including the pharyngeal tonsils, canal tonsils, palatine tonsils, and lingual tonsils, surround the pharyngeal wall and are interconnected with each other. The most important of these is the palatine tonsil (commonly known as the tonsils), which is located in the tonsillar fossa between the front and back palatal arches, one on each side. These lymphoid tissues serve as an important part of the body’s immune system, helping the overall immune system to grow and produce antibodies, and are a natural barrier in the body, an important line of defense against respiratory infections. The glands and vascular tissues of the palatine tonsils are underdeveloped early in life, and only gradually increase in size by the end of the first year as the lymphoid tissues throughout the body develop, reaching a peak in development between the ages of 4 and 10, and gradually degenerating again by the age of 14-15. Therefore, under normal circumstances, children’s tonsils appear larger and lighter red than those of adults. Tonsillitis, as it is commonly referred to, is a nonspecific inflammation of the palatine tonsils primarily, but may also be accompanied by some degree of pharyngeal mucosa and other lymphoid tissues. Fever and sore throat are usually present. In the past, tonsillitis was classified into several types, but in terms of clinical diagnosis and treatment significance, it can be divided into two categories: congestive and purulent. In the case of congestion, viral infection is the main cause, while in the case of suppuration, hemolytic streptococcal infection is the main cause. Because of the weak immune function of children, there is often an interval of about 2 weeks after each acute attack of tonsillitis, so it is not surprising that 4-6 year olds have tonsillitis several times a year. As you get older and your immune function gets better, the number of tonsillitis episodes will become less and less. Nowadays, there are various treatments for tonsillitis such as Chinese medicine, acupuncture and massage, and antibiotics, all of which have good effects. Therefore, even if your child often has tonsillitis, do not easily remove the tonsils. Only if tonsillitis is recurrent and forms foci that cause rheumatic fever, nephritis, arthritis, heart disease, or excessive hypertrophy that affects breathing, swallowing, and speech, then you can consider choosing the right time to remove the tonsils.
