In the clinic, many parents are concerned about their child’s tongue tie, and when their child has speech problems, they often worry if it is due to a short tongue tie. Some parents come to the clinic and say, “Doctor, please take a look at your child’s tongue.” I. So, is the tongue tie really that important? Let’s start with speech and language disorders. Language disorders are common developmental behavioral disorders in children, often manifesting themselves as a lack of speech, little speech or unclear speech. For example, they are two years old and still can’t speak; they say fewer words than their peers; they say “park” as “east park. Over time, these children may also develop emotional and behavioral problems, such as temper tantrums and distractions, which can affect their normal interactions and learning. The causes of language disorders include the child’s own neuropsychological development and environmental factors, including the quantity and quality of language education, the child’s exposure to adverse evaluations, and the effects of illness. The common belief that “short tongue tract” causes language problems in children is not entirely true, because the incidence of short tongue tracts, which can lead to language developmental disorders, is very low, and only two or three out of 300 children with poor speech need surgery for short tongue tracts. Second, so, children with speech disorders, can we wait and wait, the child grows up naturally? Some children have speech delay and will speak when they grow up, but not every child is so “lucky”, and it is often found clinically that children have hearing impairment, intellectual disability and even autism. This will have a profound impact on the child’s future schooling and normal life.
