Anesthesia is required for tongue tie cutting in three-week-old babies, and it is recommended that babies who can cooperate choose local anesthesia, while those who cannot should opt for surgery under general anesthesia. Tongue tie cutting for three-week-old babies is not a big operation, but it will cause pain, and usually need to be stitched up after the operation, so it is recommended that anesthesia is needed before the operation. After local anesthesia, the tongue can be fixed better, there is no pain when cutting the tongue tie, and the suture is also painless, so the baby can better cooperate with the surgery. For babies who can’t even have local anesthesia and can’t guarantee full cooperation with the surgery, you can choose to do the ligature surgery under general anesthesia to avoid other positional contusions caused by the baby’s fidgeting during the ligature cutting.
