There are two types of hypertelorism, congenital myelomeningocele and congenital bony hypertelorism. Myotonic squint is more common, and it is caused by head and neck tilt due to contracture of the sternocleidomastoid muscle on one side; osseous squint is rare, and it is due to cervical spine bone development malformation. The treatment of myelomeningocele is time-sensitive, and it is important to seize the golden time for treatment. Infants grow and develop rapidly and all organs are constantly growing and changing. A case of myotonic squint that occurs for more than 3 to 4 weeks may lead to unbalanced facial development. The following treatment methods: 1. Non-surgical treatment: For children within half a year old, non-surgical treatment can be taken with good results. Once diagnosed, treatment should be done as soon as possible. Non-surgical treatment methods can include local heat, massage, and traction, etc. Treatment must be done in a regular hospital. 2.Surgical treatment: surgical treatment is suitable for patients who have been treated conservatively for more than 6 months and those who have obvious oblique neck deformity under 12 years old. The specific surgical methods are sternocleidomastoidectomy, partial sternocleidomastoidectomy and sternocleidomastoid lengthening. Sternocleidomastoidectomy is the more commonly used surgical procedure. Infantile sternocleidomastoid is a relatively common condition that can be completely cured in most children if treated correctly and effectively at an early stage.
