If the tonsils are enlarged bilaterally, it depends on the degree of enlargement and whether there are recurrent tonsil infections, and different treatment methods are adopted. If the tonsils are simply enlarged and have never been infected with pus, there is no need for treatment. If the tonsils are simply enlarged to degree II or III, causing open-mouth breathing, snoring, apnea, or even suffocation during sleep, the tonsils need to be surgically removed bilaterally. If it is acute bilateral tonsillitis caused by a cold, which causes congestion and enlargement of the tonsils, it can be treated with local nebulized inhalation, together with sedation of sensitive antibiotics and antiviral drugs. If the tonsils are enlarged due to chronic tonsillar hyperplasia caused by repeated infections and inflammation, bilateral tonsils should be surgically removed after the condition has stabilized. If the enlargement is caused by a malignant tumor of the tonsils, an enlarged tonsillectomy should be performed.
