Cysts at the base of the tongue are usually caused by a blockage of the sublingual gland and require surgical treatment to remove the blocked sublingual gland completely, mainly in adolescents, and the whole procedure requires hospitalization and is performed under general anesthesia. Cysts at the base of the tongue are rarely malignant and there is no need to worry too much. If the cyst is removed without removing the sublingual gland, the cyst will soon recur without any healing effect, and only then the sublingual gland needs to be removed completely. After removing the sublingual gland, it will not affect the oral environment too much. There are many glands in the oral cavity that secrete saliva, and the sublingual gland is only one of the smaller glands, so it will not affect the patient’s normal life after removing it.
