Cysts under the tongue can be treated with medications such as hypertonic sodium chloride, but surgery is usually the treatment of choice. Sublingual cysts are mucus cysts that occur at the floor of the mouth and form as retention cysts due to obstruction of the ducts of the sublingual or submandibular gland. Different treatment options are available depending on the condition. Pharmacological treatment is commonly used to cause cell degeneration and atrophy, destruction of the cyst wall, and then mechanization and disappearance by hypertonic sodium chloride or cauterizing drugs such as trichloroacetic acid. However, surgery is usually chosen to completely remove the cyst and the gland together, which can effectively relieve the symptoms and prevent recurrence. If the cyst is large and complete removal is difficult, the anterior wall of the cyst can be removed and the edges of the cyst can be sutured to the oral mucosa to relieve symptoms. Most cysts under the tongue have a good prognosis, but there is a risk of recurrence if treatment is incomplete. It is recommended that standardized treatment and medication be administered under the guidance of a professional doctor to avoid recurrence.
