Sublingual cysts are treated by surgical removal of the sublingual gland. If the cyst is not large enough, an incision can be made inside the mouth to remove the cyst. Since patients with sublingual glands have lesions at the floor of the mouth, the surgical approach depends on the size of the cyst. The procedure is performed by making an arcuate incision in the lateral sublingual crease in the direction of the duct travel, from anterior to posterior, and inserting a curved hemostat into the incision for blunt separation to expose the sublingual gland and cyst. After the sublingual gland is revealed, the tissue is gradually separated to free it, and the sublingual gland and cyst are finally removed completely. After excision of the tissue, the wound is flushed with saline to stop bleeding, and the mucosal incision at the floor of the mouth is finally sutured and a drainage strip is placed. If the cyst is more extensive or even spreads to other parts of the body, an incision is made under the patient’s jaw to remove the cyst.
