It can be caused by a variety of diseases and common causes: congenital myotonic squint, congenital bony squint, infection, optic squint, otogenic squint, neurological squint, habitual squint, benign paroxysmal squint in infants, etc. Among them, congenital myotonic squint is the most common cause of pediatric squint. Congenital myotonic squint is usually found one week after birth with a protruding mass in the middle and lower part of the sternocleidomastoid muscle on one side of the neck, with hard texture, normal skin temperature and no pressure pain. If not treated reasonably in infancy, the deformity will be aggravated with age, and its therapeutic effect will be reduced, which will bring adverse effects to the physical and mental health of the children. The treatment of congenital myotrabismus emphasizes: early diagnosis and early treatment. Treatment methods can be divided into: conservative non-surgical treatment and surgical treatment. Non-surgical treatment: It is suitable for infants within 1 year old and 6 months old, with sternocleidomastoid muscle massage and manual correction during the daytime and sandbag to keep the head in the corrected position when the child sleeps at night. Manipulation: The operator fixes the shoulder joint on the affected side with one hand, gradually pulls the head to the healthy side with the other hand, and then turns the chin to the affected side, 100-200 times a day, insist on more than half a year to one year, if there is no improvement, facial excitation deformity or less than 1 year old, sternocleidomastoid contracture is very obvious, the rotation of the neck to the affected side is obviously limited, the face has appeared secondary The treatment should be changed to surgery if the deformity is secondary. The ideal age for surgical treatment is 1-4 years old, and there are many surgical methods, such as sternocleidomastoid head and clavicle head severing at the lower end of the sternocleidomastoid muscle, upper mastoid end severing or upper and lower end severing at the same time, as well as the release of the surrounding contracted fascia and soft tissue, and sometimes partial or subtotal sternocleidomastoid excision. Effective postoperative fixation and proper manipulation are important measures to prevent recurrence.
