What happens to a newborn baby with a lopsided neck? Some newborns are born well, but their necks are often tilted to one side 10-20 days after birth. A careful mother will find a round or oval lump on the sick side of the child’s neck, about 2-3 cm in diameter, hard, movable, painless to touch, normal skin on the surface, and not hot to touch. The child’s head is tilted toward the side with the mass, the ear on the sick side is close to the clavicle, the face is not square, and the jaw and face are turned toward the side without the mass, forming a slanting neck. There are many causes of the oblique neck, ranging from congenital genetic factors to improper birth practices, mostly as a result of muscle lesions. The pathological changes of the oblique neck are caused by contracture of the sternocleidomastoid muscle on the diseased side. During delivery, due to the abnormal position of the fetus, one side of the cervical muscle, especially the sternocleidomastoid muscle, may be born in an abnormal position of the fetus, resulting in connective tissue, shortening and inability to stretch, or due to strong traction damage to the sternocleidomastoid muscle during delivery and the occurrence of hematoma, mostly seen in breech delivery or delivery of the shoulder delivery difficulties. Some congenital genetic factors, such as a family gene that causes sternocleidomastoid contracture in the offspring, can cause congenital oblique neck. Various congenital developmental anomalies such as the first cervical vertebra joining the posterior skull, the combination of the first and second cervical vertebrae, cervical vertebral deformities, and the presence of cervical ribs can all lead to a squint. What are the treatment methods for neonatal squint? Use a sandbag or pillow to keep the child’s head and neck in an upright position. Let the light source amplitude on the side with the mass, because the child’s head is often turned towards the light, which helps to prevent muscle contracture on the diseased side. At the sternocleidomastoid mass, massage and massage therapy is done. Fix both sides of the child’s shoulders, then give passive movements to the head, rotate the jaw to the diseased side, and rotate the head to the normal side, 100 to 150 times a day. Let the baby lie on his mother’s back, with both feet close to his mother’s abdomen and his head outside the two knees, and gently turn the child’s head to the healthy side with both hands for 20 to 25 times, 2 to 3 times a day, for half a year. After the above treatment, many children have different degrees of improvement or cure of their oblique neck. If there is still no obvious improvement after 6 months, we should take the child to hospital for examination and consider early surgical orthopedic treatment to avoid causing deformity of the head and face of the child.
