Sublingual gland cysts in four-year-old children are recommended to go to the hospital for intervention through sclerotherapy, laser therapy, oral medication, and surgery after evaluation by a physician. 1. Sclerotherapy: local injections of agents such as pingyangmycin and anhydrous ethanol can be used to fibrose the local tissues to eliminate the cyst. 2. Laser therapy: including CO₂ laser, diode laser, etc., to “burn” the cyst locally, to achieve the purpose of removing the cyst, sealing the blood vessels, reducing bleeding, reducing inflammatory reaction, reducing scar contraction, and so on. 3. Oral drug treatment: Oral nickel gluconate can be taken to control the condition to a certain extent. 4. Surgery: For children who are not well controlled by the above treatments, have progressive enlargement, or have a large cyst that affects their pronunciation or breathing, surgery can be considered, and a common surgical procedure is resection of the sublingual gland. For sublingual gland cysts in 4-year-old children, it is recommended to go to the hospital in time; medications should be used under the guidance of clinicians; the above treatments are not allowed to be carried out by oneself.
