Congenital myotonic plagiocephaly is one of the commonly known “crooked necks”. The deformity can be present from birth or can appear 2-3 weeks after birth. At the beginning of the disease, the head movement is slightly restricted, but there is no obvious sloping neck phenomenon. Some patients do not remain oblique neck; in many patients, if untreated, the muscle gradually fibrosis, contracture hardening, the formation of hard bundle-like strips next to the neck, head due to the pull of the contracted muscle and oblique neck deformity, muscle shortening side of the face also deformed. If the deformity is not corrected in time, the facial deformation will worsen and eventually the cranial development will be asymmetrical and the cervical vertebrae and even the upper thoracic vertebrae will develop scoliosis deformity. Try to place the child’s head in the corrected position; put the affected side close to the breast when breastfeeding; when lying in bed, make the affected side to the side where there is light and the mother often moves around; properly padded pillow. For manual traction, the child is placed in the supine position, the parent holds the child’s head and slowly rotates it, gradually increasing the angle of rotation, and tilting the neck to the healthy side as much as possible, the operation should be gentle and can last for l0-15 minutes each time. Massage, gentle massage of the swelling, stretching the contracted sternocleidomastoid muscle, each stretching muscle duration can be 2 to 3 seconds, 4 to 6 times a day. Local physiotherapy such as infrared irradiation, or local heat application to soften the scar. Surgery is required for children over 1 year of age who are not successful with the above treatments or who have been misdiagnosed.
