Pediatric myotonic neck is a very common clinical condition. It is mainly caused by contracture of the sternocleidomastoid muscle, which pulls the neck, manifesting as a special postural deformity with the head and neck deviating to the affected side and the jaw turning to the healthy side. As the child grows older, the deformity will gradually worsen, seriously affecting the health of the child. In this article, we will answer several questions that parents are concerned about. 1.What are the types of pediatric squint? What are the causes of each of these types of squint? There are many types of pediatric squint, which can be divided into congenital squint and acquired squint; according to the causes, they can also be divided into muscular squint, ophthalmic squint, bony squint, otogenic squint, habitual squint, and squint caused by head and neck infection. Myotonic squint is caused by contracture of sternocleidomastoid muscle; ophthalmic squint is caused by visual impairment, such as refractive error, ocular muscle paralysis, eyelid ptosis, etc., which results in head and neck outward slant when viewing objects; osseous squint is caused by congenital malformation of cervical vertebrae, including cervical hemivertebrae, dentate convexity malformation, cervical fusion, etc.; otogenic squint is mainly caused by congenital hearing impairment, which leads to the patient’s habit of listening to the sound on the side of the head, resulting in postural squint; in addition, the Head and neck infections, such as laryngitis, tonsillitis and lymphadenitis on one side of the head and neck, can also lead to temporary squinting. 2.Why is myotonic squint in children congenital? Is there a genetic factor? Pediatric myotonic squint is due to congenital contracture of sternocleidomastoid muscle. The child shows symptoms such as head and neck tilt, sternocleidomastoid muscle tension and restricted head and neck movement at birth. It is uncertain whether there is a genetic factor for myotonic squint. 3.What are the general causes of pediatric myotonic levator neck? It is generally believed that myotonic squamous neck is related to abnormal fetal position and difficult delivery and birth injury. The incidence of myotrabismus is significantly higher in abnormal fetal position, especially in breech birth. Difficult delivery or birth injury during delivery can cause restriction of blood flow to the sternocleidomastoid muscle, ischemia, hemorrhage, hematoma mechanization, muscle fiber degeneration, and contracture of the sternocleidomastoid muscle, which leads to the occurrence of myotrabismus. 4. Is natural delivery more likely to cause myoclonus than cesarean delivery? Although obstructed labor and birth injury can significantly increase the incidence of myelomeningocele, there is no research that proves that normal natural birth is more likely to cause myelomeningocele in children than cesarean delivery. 5. Is myelomeningocele associated with improper sleeping position or insufficient exercise during the mother’s pregnancy? There are no studies on the relationship between myelomeningocele and the mother’s sleeping position and the amount of exercise during pregnancy, so it cannot be assumed that these two factors are related to the occurrence of myelomeningocele. 6. Can holding a baby or nursing in the same position for a long time cause myelomenorrhea? Is this myelomeningocele? No. Holding a baby or nursing in the same position for a long time may cause the child’s head and neck to be tilted to one side, but this is not myelomeningocele, but postural or habitual squint. The sternocleidomastoid muscle in the neck is not tense and the head and neck are moving well. It can be gradually corrected by itself after changing the holding position frequently. 7.How to distinguish whether myopic strabismus causes strabismus or strabismus causes strabismus in children? Strabismus is mainly caused by paralysis of the extraocular muscles. When the patient pays attention to an object, the image of the object in the strabismic eye cannot fall on the central recess of the retina and needs to be corrected by head and neck tilting. The following methods can be used to distinguish myotonic strabismus from strabismus: first, physical examination, myotonic strabismus may reveal a hard mass in the sternocleidomastoid muscle of the neck or contracture and tension of the sternocleidomastoid muscle, accompanied by limited head and neck movement; while strabismus caused by strabismus has a normal sternocleidomastoid muscle and normal head and neck movement, but accompanied by impaired eye movement; second, ultrasound examination of the neck, myotonic strabismus indicates that the sternocleidomastoid muscle Echo enhancement and muscle fiber disorder. 8.How to treat pediatric myotonic squint? Once a child is diagnosed with myotonic levator, he or she must receive treatment, otherwise myotonic levator will be aggravated as the child grows older. At present, massage and physiotherapy are recommended for myelomeningocele within 1 year old, and more than half of the children can be cured through massage and physiotherapy. For children over 1 year old, surgery is recommended. The surgical method is sternocleidomastoid muscle release, and after discharge from the hospital with functional exercises of the head and neck, good results can be obtained. The procedure is performed in a short hospital stay (3 days) and recovery is rapid.
