The lingual ligament is a strip of tissue attached between the tongue root and the mucosa of the floor of the mouth. Normally, the lingual ligament recedes under the tongue root after birth, but if the lingual ligament does not recede under the tongue root after birth, the tip of the tongue cannot be upturned and the tongue tip becomes “W”-shaped when the tongue is extended, which is commonly known as short lingual ligament. The incidence is about 4%. The age of lingual ligament correction can be traced back to the 18th century, when midwives cut the lingual ligament directly after the birth of a child, thinking it would improve the baby’s ability to breastfeed. In infancy, the tongue tie is attached closer to the tip of the tongue, and as it gets older, the tongue tie gradually drops relatively close to the root of the tongue and becomes looser, so not all babies with short tongue ties need correction. Second, the surgery and anesthesia options for children under 2 years of age is not possible to normal cooperation, there are sublingual arterioles and submandibular ducts on both sides of the tongue ligament below, such as children cry and resist, it may damage the blood vessels caused by bleeding, so for different cases of tongue ligament need to use different methods of anesthesia. For children with thin lingual ligament, surface anesthesia can be used, and the ligament can be cut directly with scissors or electric knife, and minimal bleeding is usually not required for suturing. For older children who can cooperate, the surgery can be performed under local injection anesthesia, and the ligament can be cut and sutured to reduce adhesions, referred to as “cross-cutting and longitudinal suturing”. For children with thick lingual ties or extremely uncooperative children who need to be sutured, general anesthesia should be used to avoid unnecessary surgical risks. In our work, we have seen many children with short lingual ligaments who have very clear articulation, while many children with unclear articulation do not have short lingual ligaments. Therefore, lingual ligament correction surgery cannot solve the problem of inaccurate pronunciation, and postoperative speech training is also very important.
