Varicose veins at the base of the tongue will show up as a foreign body sensation when swallowing, and may even rupture and bleed through friction, and it is difficult to stop bleeding. Therefore, varicose veins at the base of the tongue can be treated by surgery, which is divided into two kinds: 1) Remove the varicose vein, which can reduce the patient’s symptom and promote the patient’s recovery, but this kind of surgery is more painful. 2) Inject sclerosing agent drugs into the varicose vein, through the effect of chemical ablation, the sclerosing agent damages the endothelium, and the endothelium is damaged, then the endothelium and the surrounding tissues form a granuloma, which is a kind of sterile inflammation, and eventually through the body of the body. Granuloma, a sterile inflammation, is eventually absorbed through the body to form dense fibrous strips, and blood cannot pass through the lumen of the blood vessel. Therefore, the treatment of varicose veins can be achieved and the symptoms caused by varicose veins can be eliminated. It is a very minimally invasive treatment that does not require anesthesia, and the patient’s sensation is like a needle in the base of the tongue, which is relatively short and does not affect the patient’s normal swallowing.
