The best time to treat an infant with a short tongue tie is within the first month of life or between the ages of 4 and 5 years. A short tongue tie can seriously affect not only the child’s speech and communication functions, including slurred speech and late speech, but also normal feeding functions such as sucking and chewing. Short tongue tie can be broadly classified into two main causes: congenital defects, and acquired diseases. For patients with congenital short tongue tie, it is recommended that they undergo tongue tie correction within one month of birth to reduce the adverse effects on their speech and communication functions later in life. For patients with short lingual ligament during development, lingual ligament trimming can be performed between the ages of 4 and 5. This is when the child’s lingual ligament has stabilized and the tissue is relatively thin, which is more conducive to postoperative wound repair and reduces the risk of scar formation. After receiving the treatment, parents should strengthen the child’s daily speech training and create conditions for the exercise of articulation, which can restore the patient’s normal articulation function more quickly.
