Sublingual cysts are usually not self-healing and patients should prefer surgical treatment to remove the cyst and the associated gland together, which can basically achieve a radical effect and effectively prevent recurrence. Sublingual cysts may be sublingual cysts, which are saliva-secreting glands. If the ducts of the sublingual glands are blocked and the saliva secreted cannot be discharged properly, sublingual cysts will form. The sublingual cyst is not a tumor, but a localized swelling formed by the accumulation of saliva. If the cyst is large enough to interfere with eating, it usually does not heal on its own and requires surgical removal of the cyst and the sublingual gland together. Sublingual cysts may also be small cysts on the abdomen of the tongue, usually of mucous gland origin, which have the function of secreting saliva and are located on the oral mucosa. If their opening is obstructed, they can form mucous gland cysts and need to be surgically removed. After surgical treatment, patients with sublingual cysts should keep their mouth clean, they can rinse their mouth with light salt water, and eat a light diet during the recovery period, and do not eat spicy and stimulating foods.
