Short tongue tie is a congenital disease and a common clinical symptom. Often, children’s families will bring their children to the stomatology department of the hospital to check whether the tongue tie is too short and ask for surgical treatment, and the most important clinical effect of short tongue tie is that it affects the child’s pronunciation. The main clinical effect of the short tongue tie is that it affects the child’s articulation, which may be unclear when pronouncing special sounds. There are two clinical concepts of surgery for short tongue tie, one of which is that it is recommended to operate between the ages of 1-2 years because this is the time when the patient is beginning to form the habit of articulation. Early surgery at this time is beneficial for patients with short tongue tie to practice their pronunciation. However, there are some people who suggest that surgery for short tongue tie should be performed after the age of 4 years old, the reason is that the development of speech center is not perfect before the age of 4 years old, and some children’s tongue tie itself is not short, so even if the surgery is performed after the age of 4 years old, the child’s pronunciation will not be affected at all.
