Tonsil removal has both advantages and disadvantages, the “advantage” being the relief of the disease and the “disadvantage” being the lack of local immune function and the possibility of surgical complications. Whether or not to remove the tonsils should be analyzed according to the patient’s tonsil lesions and listen to the doctor’s professional advice. Tonsils are located in the pharynx of the human body, so they are often in contact with germs and foreign bodies that can easily be hidden. The tonsils implement their anti-bacterial and anti-viral defense function in the pharynx by producing lymphocytes and antibodies. However, when the body is overworked, cold, etc., resistance drops, tonsil epidermal epithelial defense function is weakened, the gland secretion function is reduced, the tonsils will suffer from pathogen infection and inflammation. Inflammation of the tonsils, if recurrent, may lead to otitis media, sinusitis, peritonsillar abscess and other complications, and the spread of inflammation downward can lead to bronchitis, pneumonia and so on. Enlarged tonsils due to inflammation may cause difficulty in swallowing, speech disorders and affect normal breathing. Tonsillectomy is beneficial as it prevents these conditions from occurring. The main disadvantage of tonsil removal is that tonsils are immune organs, which are more important for children with immature immune function, and removing tonsils from children will lower their body resistance. The tonsils also have a glandular secretion function, and some patients experience dry mouth after tonsillectomy. Therefore, if you are considering tonsil removal, it is recommended that you consult a doctor who will give you professional advice after combining the results of your examination with the condition of your tonsils, and you should not make the diagnosis on your own.
