Baby N.M.N, 19 months old, Hanoi was taken to the doctor by her mother due to slow speaking. Although he knows how to say a few simple words from one year old, he has not been able to say new words until now. Through examination at An Viet Hospital, Dr. Ha To Nhu diagnosed, children with tongue (or short tongue) is a mild birth defect but can greatly affect the ability to suck, pronounce, even develop their language. This condition occurs when the ligament under the tongue (thin mucosal membranes attached to the tongue) is too short, causing the tongue to move limited.
Another case is patient N.T.A, 5 years old in Hung Yen, who also had a long stall. The family thought that this condition would go away on its own when the child grew up, so they did not take him to the doctor. When preparing for first grade, the child was still speechless, so the parents took him for a check-up and confirmed a language complaint.

"Currently, more and more children are detected early and given timely intervention. Previously, many parents ignored this unusual sign, said Dr. Nhu.
Doctor Nhu analyzed: tongue brake (also known as short tongue brake, tongue sticking) is a mild birth defect, in which the tongue brake (the thin layer of fluid lying under the tongue) is short, thick and tense, causing limited tongue movement. This is a cause that few people know about, a birth defect, limiting normal tongue movement and affecting the child's speech.
Children with tongue sticking often have difficulty sucking in infants, difficulty swallowing in children who are feeding, slow to speak, difficult to pronounce, and grope: children mainly pronounce the following additions incorrectly: r, kh, tr, l...
The tongue is divided into 4 levels from light to heavy according to the Kotlow classification. In cases of level 3, 4 or showing signs of language dysfunction, children will be prescribed surgery.
"Usually, after surgery, the tongue cutting site often has a white spot. That is a normal thing after laser surgery, parents should not worry too much. These phenomena will go away and the wound will heal after a few weeks.
It is necessary to monitor child care, not let children hold back or bite hard objects to avoid bleeding, not let children touch the surgical area to avoid infection, and give children medicine as prescribed by the doctor" Dr. Nhu recommended.
