Tongue frenulum is too short, which means that the membrane under the tongue (tongue frenulum) is too short, so that the tongue cannot move freely. This situation may affect children's diet, speech and breathing.

If the child is diagnosed as having a short lingual frenum, the following treatment methods can be considered:

1. Tongue frenectomy: This is a common treatment. Cut the lingual frenulum into a longer length by surgery, so that the tongue can move freely. This kind of operation is usually performed under local anesthesia, and attention should be paid to rest and diet after operation.

2. Traction therapy: this method is suitable for mild short tongue frenulum, which can be relieved by gently stretching the tongue with special instruments or fingers. This method needs long-term persistence, and the effect may not be as obvious as surgical treatment.

3. Language therapy: For some patients with mild short lingual frenulum, language therapy can help them improve their pronunciation and oral muscle control. This method needs the guidance and training of professional speech therapists.

It should be noted that patients with different degrees of lingual frenulum apply different treatment methods, and appropriate treatment methods should be selected according to specific conditions. At the same time, it is best to consult a professional doctor before treatment and conduct a comprehensive evaluation.
