The causes of pediatric myotonic squamous neck The causes of this disease have not been fully determined. In addition to the theory of congenital malformation, many scholars believe that it is caused by myofibrosis due to local ischemia of the sternocleidomastoid muscle. There are three possible causes of ischemia: malnutrition of the pregnant woman; malposition of the fetus during pregnancy, such as a long-standing head position to one side; injury, such as bleeding of the sternocleidomastoid muscle during delivery due to extrusion by the birth canal or forceps, and contracture of the hematoma; or malposition of the fetus during delivery, which obstructs the blood supply to the sternocleidomastoid muscle and causes ischemic changes in the tissue. There are other causes of squint, but they are rare in young children, including: 1) inflammation of the neck tissue, such as acute lymphadenitis, which may cause the head to be tilted to one side due to swelling and pain; 2) sports injuries and poor sleeping posture may also cause muscle spasm on one side of the neck, resulting in asymmetric neck movement; 3) asymmetric vision may also cause the head to be tilted; 4) neurological diseases such as cerebral palsy may also cause abnormal contraction of the neck muscles. 4. Neurological diseases such as cerebral palsy may also cause abnormal contraction of the neck muscles. The symptoms are similar to those of a squint. If left untreated, myelomeningocele may affect the development of the affected side of the face, and the healthy half of the face may also undergo adaptive changes, such as large cheeks on one side and small cheeks on the other side, crooked nose and squinting eyes, making the face asymmetrical. Severe cases may be accompanied by compensatory scoliosis of the thoracic spine, which can cause lifelong pain to the affected child.
