Due to the pulling of the sternocleidomastoid muscle, the neck is tilted and the head is inclined to the affected side, while the jaw is turned to the healthy side, forming a special “crooked neck” posture deformity. The cause is still not fully understood. There is no abnormality when the baby is born, but after about 7-10 days there is a hard lump in the neck, which is round or oval in shape, the surface of the lump is not red, the temperature is normal, and there is no pressure and pain. 2-3 months later, the lump gradually shrinks, and it disappears completely after about 6-8 months. After the disappearance of the mass, the sternocleidomastoid muscle of the affected side starts to protrude, become tight and short, the head is inclined to the affected side, the neck movement is restricted, and the face gradually becomes asymmetric, with the face of the affected side being short and flat, and that of the healthy side being long and round, and the two eyes, the ears and the corners of the mouth are not at the same level. If not reasonably treated in infancy and childhood, the deformity gradually worsens with age, and its therapeutic effect also decreases, which will bring adverse effects to the children physically and mentally. Therefore, early detection and early treatment is crucial. 2, ophthalmoplegia The second common cause of pediatric “crooked neck” is “ophthalmoplegia”, that is to say, due to children’s eye diseases caused by “crooked neck”. There are many childhood eye diseases that can cause a crooked neck, such as severe amblyopia, nearsightedness, farsightedness, and strabismus due to congenital upper eyelid hypoplasia, etc. It is important to emphasize the importance of childhood eye diseases. It is important to pay attention to children’s eye diseases, such as children’s amblyopia, myopia, hyperopia, most of them can be achieved through the prescription of glasses to treat, correct the “crooked neck”. But some diseases, such as congenital hypoplasia of the upper eyelid muscle, must be treated through surgical treatment to cure “strabismus”, from the root of the “ocular strabismus”. The third type is “bony strabismus” caused by cervical spine developmental disorder. Congenital cervical spine developmental disorders, such as hemivertebral deformity, can lead to cervical spine curvature, resulting in “crooked neck” deformity. This deformity is rare and worsens with age. Surgery is the only treatment, and generally speaking, the earlier the surgery, the better the treatment effect. The fourth cause of “crooked neck” in children is “auricular tilt”, which means it is caused by ear problems in children. Some causes in childhood can lead to hearing loss in one ear, which can lead to “crooked neck” symptoms. For example, unilateral congenital deafness, hearing loss due to medication, and cerumen impaction. 5, habitual tilt neck The fifth is due to poor feeding habits resulting in habitual tilt neck. It can be corrected by changing habits. ① sleep the baby’s head and neck in the corrected position, and then fixed with a small pillow; ② according to the baby like to light, sound this physiological characteristics, pay attention to adjust the position of the bed, so that the sun, light or radio, television and other light or sound from the back of the baby’s head in. If the baby’s brain to the left, let the light and sound from the right side in, so that the baby’s head will face the light, sound position, time, the neck is not crooked; ③ breastfeeding, the mother should be from the sick side of the opposite direction of breastfeeding, so that babies turn their faces to the milk, mothers usually hold the child, pay attention to the hand will be turned to the correct position of the head. The above are five causes of children’s “crooked neck” disease, different causes of cranial neck treatment methods are different, not all need massage, manipulation of the movement. In addition, there are some other conditions that can lead to the above symptoms, such as infantile benign paroxysmal cervical tilt, gastroesophageal reflux, intracranial tumors, etc. If your baby has symptoms of a crooked neck, it is recommended that you go to the hospital to ask a specialist for further examination to confirm the diagnosis.
