The tongue tie is too short, to cut or not to cut, some say cut some say not to cut can also be, some say cut at birth, and others say cut after 2 years old. This is a problem for many parents. First of all, whether to cut or not depends on whether the child’s ligament is really short, so short that it affects the normal forward extension and upward roll, so much so that it affects eating and future pronunciation, if so, of course, it is recommended to cut. How to determine whether the tongue tethering will affect the function of the child, you can observe the forward extension of the tongue, if it can extend beyond the red edge of the lower lip, this generally has little impact on the function. If the tongue can be rolled up, you can rest assured. Again, look at when exactly to cut. I think it can be summarized into 4 periods. First, at birth, if the child is diagnosed as having a short tongue tie, the tongue tie is short and thin, and there is little blood flow, so cutting in this case avoids the need for stitches and anesthesia when the child is older. However, there are many children who are prone to re-adhesion, which requires very careful family care. Second, within 2 years of age, in this case, for short and thick tongue tie, which affects the function and requires stitches, it is recommended to perform lengthening of the tongue tie under general anesthesia. For the third type of children who cannot cooperate after the age of 2, our center has set up a lengthening of the tongue tie under sedation at night. This is because sedation is relatively safe for children over 2 years old. Fourth, if the child can cooperate, it can be considered under local anesthesia if the child can cooperate. It is recommended that it be considered only at the age of 4 years or older.
