Enlarged tonsils may cause facial changes. Mildly enlarged tonsils usually do not cause facial changes, but usually cause secretory otitis media, rhinitis, sinusitis and other complications, resulting in hearing loss, tinnitus, runny ears and other symptoms. Heavily enlarged and untreated tonsils may cause facial changes. This is because patients with severely enlarged tonsils often breathe with their mouths open, which can affect the development of the facial bones, resulting in facial changes such as elongated maxilla, high arched jaws, irregular teeth, protruding upper incisors, thicker lips, and lack of expression. In addition to the above symptoms, patients with enlarged tonsils may also have symptoms such as poor nutritional development, slow response, poor concentration, night terrors, teeth grinding, and enuresis. Therefore, patients with enlarged tonsils should go to the hospital in a timely manner and receive standardized treatment as soon as possible under the guidance of the doctor to avoid further aggravation of the condition.
