Tongue tie shortening is mainly caused by the abnormal attachment position of tongue tie which restricts the tongue mobility and gives rise to a number of problems. First of all, this disease is not a serious disease, but with the high standard of living, parents’ demand for their children’s future quality of life is also increasing day by day, and they don’t want their children to have any gap or difference with other children, so their concern is also gradually higher, which is also a manifestation of the improvement of everyone’s overall standard of living. Here I would like to talk about my insights on this disease and surgery with some of my own experiences. Common abnormalities of short tongue tie: 1, repeated episodes of ulceration at the tongue tie when teething. 2.Stretching the tongue out of the mouth and lips, or stretching the tongue when the tip of the tongue is forked or “w” shape. 3. Speech is not clear. 4.The gap between the lower front teeth is sometimes related to the tongue tie. 5.Because of learning vocal music, some musical notes need to be issued to require a higher degree of flexibility of the tongue than the ordinary pronunciation of the consultation. Diagnosis: 1. It is necessary to see whether the position of the tongue tie attached to the tongue is too close to the tip of the tongue and the bed of the teeth. 2. 2.It is necessary to see whether the shape of the tip of the tongue after tongue extension is bifurcated or whether the tongue extension is heavily restricted. Surgical methods: 1. Simple local anesthesia: scissors, electric knife or laser to cut the abnormal tongue tie, usually without suture. This method is suitable for children with thin tongue tie, not much bleeding after cutting and the wound is not easy to adhere to the child. Advantages: Simple. Disadvantages: some children may be slightly poorer than normal, may not be able to achieve the normal level, may require a second operation. 2.Complex local anesthesia: Generally, children over 6 years old who can cooperate can undergo the surgery, and the tongue tie needs to be sutured after the surgery to reduce the chance of wound adhesion. Advantages: local anesthesia, good surgical results. Disadvantages: need to cooperate with the child. 3, general anesthesia surgery: mostly for children who can not cooperate with the operation and need to sew the wound. Advantages: can be a basic operation to achieve more satisfactory results. Disadvantages: need to be hospitalized, the operation cost is relatively high.
