Tilt neck may be caused by neck muscle contracture, abnormal development of cervical vertebrae, genetic factors and other factors. 1. Cervical muscle contracture: mainly one side of the sternocleidomastoid muscle fibrosis, contracture, caused by the sternocleidomastoid muscle degeneration, birth injury during delivery or difficult to give birth may be the sternocleidomastoid muscle ischemia, hemorrhage, hematoma mechanization, the cause of muscle fiber degeneration. 2. Abnormal development of cervical vertebrae: the cervical spine development process due to abnormal development of the vertebrae caused by the oblique neck, such as vertebral body formation disorders (half-vertebral body, wedge vertebrae), abnormal fusion of the vertebrae (block vertebrae, vertebral body segmentation imperfections), odontoclastomia, and so on. 3. Genetic factors: Since children are born with cervical deformity, it may also be related to the genes of their parents. At present, there is no cure for strabismus, but with timely treatment, improvement of daily habits and strict self-management, the symptoms of strabismus can be improved and a better therapeutic effect can be achieved.
