Tonsil enlargement is divided into three degrees, I degree that does not exceed the tonsil fossa, not more than the pharyngeal and palatal arches, II degree that is more than the pharyngeal and palatal arches, not to the uvula, III degree is close to the midline, to the uvula on both sides of the tonsils. Tonsil enlargement and tonsil lesions are not proportional, not necessarily tonsil enlargement of tonsil patients tonsillitis is serious, cryptogenic tonsillitis tonsils are very small, tonsil gland ducts are blocked, inflammation can not be discharged, the patient’s symptoms are more serious, and become focally tonsil. Tonsils III degree enlargement also has some damage to people, especially children, can be combined with adenoid hypertrophy, causing upper airway obstruction, sleep apnea hypoventilation syndrome, need to be actively dealt with. There are also some adult snoring, the patient’s tonsils are also enlarged, although not inflammation, but become the most important organ of upper airway obstruction, also need to be surgically removed. Enlarged tonsils and disease are not proportional, found tonsil lesions should go to the hospital for formal examination. If the tonsils become a focal point of disease, or if snoring or sleep apnea occurs with particularly enlarged tonsils, further surgical treatment is required.
