Thyroglossal cysts, as a congenital cyst of the lingual duct, usually appear during adolescence, and people with strong immunity may delay the appearance of symptoms, which can seriously affect the aesthetics and quality of life. In the early stage of the onset of thyroglossal cysts, the cysts usually appear in the neck, there is no obvious swelling and pain, the shape is mostly hemispherical, the texture is relatively tough, the pressure will be rolled from side to side, but will return to its original position. In individual cases, it may be more obvious when swallowing. The middle stage of the cyst is easier to detect, grows rapidly, can be obvious under ultrasound, and in severe cases may affect the normal secretion of the lymph nodes. It can easily become infected if pressed regularly. The cysts can be removed by surgery, which is generally risky, and can be aspirated by puncture or left to drain from the epidermis. The drained fluid is yellow in color, and some of it is accompanied by a blood-red color. If it is not removed cleanly, fistulae are likely to form repeatedly. The optimal age for surgery should be after the age of 4 years, and should not be delayed until puberty, which may lead to deterioration of the condition. In conclusion, thyroglossal cysts are multiple cysts that may recur and can only be removed by simple surgery in China, making it difficult to investigate the cause and make a difference in the genetic profile, which simply means that it is difficult to avoid and prevent.
