Congenital oblique neck is a common clinical condition characterized by asymmetrical deformities of the head and neck; the head tilts to the affected side, the jaws turn to the healthy side, and the sides of the face are asymmetrical. The disease is mostly seen in infants and children and is mostly due to fibrosis and shortening of the sternocleidomastoid muscle. The earlier the treatment, the better the outcome, so early detection by parents is essential to achieve good results. Here we will analyze from the aspects of high-risk factors and abnormal performance. First of all, which babies are more prone to develop squint? Modern medical research has shown that childhood squint may be related to the umbilical cord wrapping around the neck during fetal life, fetal malposition, low amniotic fluid and lack of necessary exercise. In other words, if your baby has any of these conditions during the fetal period, it is recommended to go to a professional medical institution for necessary exclusion. Secondly, when the baby is born, there are some abnormal manifestations that parents should pay attention to, mainly the following manifestations: 1. asymmetric bilateral eye fissures, 2. asymmetric bilateral cheeks, 3. like to turn back to one side, 4. head deviation, 5. neck mass, 6. when the baby is about 3 months old, after the vertical head, the jaw is skewed to one side. In conclusion, congenital myotonic squint, after a clear diagnosis and reasonable standardized manipulative treatment, not only the squint is corrected, but also the asymmetry of the face, which also plays a very good improvement.
