Some people are unable to stick their tongue out of their mouth or a little bit due to the short development of the tongue ligament, and they are also unable to stick their tongue upwards or lick the tip of their nose, in which case patients are advised to go to oral surgery for ligature lengthening. Ligature lengthening is a common oral surgery, which is performed under local anesthesia. After the main anesthesia, the ligature is crossed and sutured under the tongue to lengthen the length of the ligature so that it does not restrict the normal movement of the tongue. It can be done for both children and adults. After the procedure, it is important to practice speech to restore the normal movement of the tongue.
