Zhang Yanzhe, Department of Orthopedics, Second Hospital of Jilin University: Congenital squint has a cervical cause and other causes such as eye and ear. If it is a cervical cause, there are also bony and muscular squint. Therefore, it is necessary to go to the orthopedic department in the hospital and first take the cervical spine open position and lateral position, and if necessary, 3D CT reconstruction of the cervical spine is needed to clarify whether there are bony factors. If bony factors are excluded, then myelomeningocele is considered. Zhang Yanzhe, Department of Traumatology and Orthopedics, Second Hospital of Jilin University Myoclinal oblique neck can be caused by hemorrhage, hematoma and contracture of sternocleidomastoid muscle due to birth injury and other factors, or myonecrosis due to intrauterine and extrauterine infection, genetics and arterial and venous embolism. The manifestation is a stiff strip in the middle and lower part of the sternocleidomastoid muscle on one side of the neck, and the jaw turns to the healthy side. If older, various secondary deformities may appear, such as short and flat face on the affected side, long and round on the healthy side, both eyes and both ears are not in the same plane, etc. If it is determined to be myotonic squint and your child is already four years old, surgery should be performed as soon as possible.
