Congenital myotonic squint, commonly known as “big neck disease”, refers to a child’s head deviating to the affected side, face rotating to the healthy side, and a muscle mass in the sternocleidomastoid muscle visible on ultrasound of the affected side of the neck. It is also necessary to exclude the squint caused by spinal lesions and strabismus. The effectiveness of the treatment of the disease is related to the time of treatment and the nature of the mass. The earlier the treatment time, the better the outcome; soft masses recover better than hard ones. Another important point is that if parents can cooperate well with the treatment, the recovery of children with “great neck disease” can be doubled with half the effort. The importance of treatment time is emphasized above, but most of the children who come to the hospital for treatment are more than 1 month old, why? This is because of the following factors: the child was born smoothly, no difficult birth, suffocation and other unfavorable conditions, no problems with limb movement, but the parents ignore the fact that the child’s head is not erect at 2 months of age, so the oblique neck is not visible by looking at it, then how to do? At this point we have to carefully observe the child’s sleeping posture to see if his head is always to one side, and if so, then we can use our hands to feel the child’s neck muscles to see if there are any lumps. If we really do these two things, we will not delay the treatment of the sloping neck. The treatment of “Great Neck Disease” has the following aspects: 1. Tui Na: there are three steps: kneading, holding and wrenching. The medium used for massage is added with Chinese herbal ingredients to activate blood circulation and reduce swelling; 2, magnetic therapy instrument: it can improve local microcirculation; 3, Chinese herbal hot compress: the Chinese herbal medicine is chosen to relax the meridians, reduce swelling and disperse knots. 4, parents must pay attention to the affected side when feeding and teasing the child, so that the child’s face turned to the affected side, can form a pull on the affected side of the sternocleidomastoid muscle, playing a passive therapeutic role. 5. When children sleep, they can use a high-low pillow so that the head is tilted to the healthy side. Items 3, 4, and 5 above must be done by the parents themselves. Failure to adhere to and do perfunctory work, or not doing it properly, will likely delay the child’s recovery time. If a child has a large and hard sternocleidomastoid mass that does not soften significantly or become smaller after treatment, surgery may be considered after the age of 1 year.
