The characteristics of surgical correction of lingual frenulum with short beard are that the tongue can not reach the upper lip and there is a depression in the base of the tongue (the lingual frenulum is a little short and does not need treatment). The operation is simple, just cut the shoelaces under anesthesia. Pre-operation has little effect on later language. If you operate again when you are old, you will form language habits, and it is difficult to correct your voice after operation, so the sooner you operate, the better.
