Purulent tonsillitis refers to the acute purulent inflammation of the tonsils, which include the palatine tonsils, pharyngeal tonsils, and tubal tonsils. This text specifically refers to the palatine tonsils. The main cause is bacterial infection, with bacteria such as Staphylococcus and Streptococcus pneumoniae. On examination, purulent tonsillitis can be identified by enlarged tonsils with pus points on the surface. Patients may experience throat pain, fever, and sometimes accompanying symptoms such as cough and a foreign body sensation in the throat. The treatment of acute suppurative tonsillitis primarily involves penicillin and second-generation cephalosporins, and timely and effective treatment can lead to significant relief of symptoms.
