The lingual tether is a band formed by the mucosal reflex in the median abdomen of the tongue and the mucosa in the sublingual region. When newborns are born, it is common for the ligament to be attached to the anterior part of the tongue belly. Young parents mistakenly think that the tongue ligament is too short and worry that it will affect sucking and speech function and seek medical attention. After a large number of cases and observations, the tongue tethered anteriorly in newborns does not interfere with sucking. Moreover, as the child’s tongue grows, the lingual ligament moves relatively backward and true lingual tethering is rare. It is no longer advocated that newborns should have their ligatures corrected immediately after birth. Many parents think that their children’s inability to pronounce words when they are learning to speak is due to a short tongue tie, and they worry that it will affect their language learning in the future and strongly request surgery. In fact, most of the children’s early language inaccuracy is not due to short ligatures, and the children’s language development is not perfect until they are about 5 years old. The majority of children do not need surgery. Only when the child’s pronunciation is inaccurate, the rolled tongue is not allowed, other non-rolled tongue sounds are normal, and the forward extension of the tongue is limited or the lower lip cannot be extended in a W shape, then surgery is needed. Currently, it is recommended to examine the child at the age of 1-2 weeks, and if it is determined that the tongue tie is too short, then surgery will be performed.
