1, tongue tethering is too short, the medical term “tongue fixation”, clinical examination: tongue body forward extension or upward scrolling is limited, the tip of the tongue tip forward extension when the tip of the V-shaped depression, tongue tip attachment and tongue base tissue adhesion obvious. Or the tongue body cannot be rolled up freely. 2.The operation time depends on the attachment position and thickness of the tongue ligament of the child. 3.Short tongue ligament can be operated under outpatient table anesthesia, inhalation sedation anesthesia or general anesthesia in the ward. 4.Outpatient table anesthesia indications: children with thin lingual ligament and not dense attachment, generally over 6 months of age can be operated. 5, outpatient table anesthesia surgery process: specialist assessment to confirm the diagnosis – routine blood tests – check no abnormalities, surface anesthesia surgery – 15 minutes to observe the operation mouth no active bleeding – leave the hospital. 6.Outpatient inhalation sedation anesthesia for children with thick tongue tie and tightly attached, considering that there is slightly more bleeding during the operation and the child is too young to easily choke into the trachea causing asphyxia, so the age limit is above 2 years old. 7.Outpatient inhalation anesthesia surgery process: specialist assessment to confirm the diagnosis – appointment registration – blood sampling on the morning of the scheduled surgery to check blood routine, coagulation function, ECG – no abnormalities in the examination – anesthesiologist arrived to assess – inhalation sedation anesthesia + local anesthesia surgery – 30 minutes to observe no active bleeding from the operation port – leave the hospital. 8. Indications for general anesthesia surgery: for children with severe tongue fixation, obvious adhesions after the first stage of tongue fixation surgery, extremely uncooperative, obvious gag reflexes prone to vomiting, or parents who are worried about the child’s fear psychology caused by binding. 9, general anesthesia surgery process: specialist assessment to confirm the diagnosis – booking admission – whole body system examination – general anesthesia surgery – post-operative observation – the next day discharge. 10.After the operation, the child’s pronunciation is not normal immediately, but needs to correct the bad pronunciation habit through training. It is necessary to pay attention to the oral cleaning and the care of the operation port. If the operation port is infected, the scar contraction will easily pull the tongue and make the tongue tip retracted.11. Children’s slurred speech is caused by many reasons, such as complex language environment and delayed language development, etc. Short tongue tie is only one of the reasons. If the child is still unable to send simple sentences at the age of 2 or more, it is best to take the child to a specialist hospital for a specific examination. 12.Short tongue ligament does not play a decisive role in the child’s ability to speak. However, it may affect the curl of the tongue and may have an effect on the clarity of individual words in Mandarin or English. If a child has a short tongue tie that significantly limits tongue mobility (upward/forward roll), surgical repair is recommended. A better age for surgery is usually recommended before the age of 3-5 years, when the child is in the early stages of language acquisition.
