Suppurative tonsillitis is a common disease of the pharyngeal region. Therefore, the first clinical department to consult for suppurative tonsillitis is the otolaryngology department, or the ENT (Ear, Nose, and Throat) department in some hospitals. In certain specialist hospitals, such as children's hospitals, there are pediatric otolaryngology departments. For some pediatric patients, they may initially visit the pediatrics department, and some pediatricians can also treat suppurative tonsillitis. For adults, some patients may also visit the respiratory medicine department, since the pharynx is part of the upper respiratory tract, and the department of respiratory medicine also provides relevant treatment. However, fundamentally, suppurative tonsillitis should be treated in the otolaryngology department.
