Since the tongue is an important organ of the oral cavity, the first place to look at the tongue is the stomatology department, but clinically, since there are sometimes various subspecialties in stomatology, the specific department to look at the tongue should be decided according to the specific circumstances of the patient’s hospital. If the patient’s hospital only has a stomatology department, then the stomatology department is perfectly fine to see the tongue. However, if the patient’s hospital has a more detailed subspecialty of stomatology, then it is necessary to refer to a different department depending on the specific tongue condition. If it is a cyst or tumor of the tongue, such as anterior tongue cyst, sublingual gland cyst or some benign tumors of the tongue or malignant tongue cancer, these should be viewed by the oral and maxillofacial surgery department of the stomatology department, because these diseases require surgery. If there is a problem with the tongue, or an ulcer on the mucosa of the tongue, or a change in the color of the mucosa of the tongue or the papillae of the tongue, then the oral mucosa department should be consulted, and most of these conditions can be treated with medication.
