Tongue tie is the congenital anomaly which is manifested by an abnormally short and thick lingual frenulum so that a condition outside of the range of normal anatomic or functional capability. In general, the surgical correction is the treatment of choice: release of tongue tie and closure. We compared the traditional frenotomy with laser frenotomy using Nd：YAG laser to treat 67 cases of tongue tie during a period of JAN. 1993 through Feb. 1996. The advantages of laser frenotomy were decreased blood loss and operation time. So we had a conclusion as the adequate use of laser frenotomy with suture was a good surgical procedure for correction of tongue tie.
