Inconsistency in the size of the two sides of the newborn’s face is generally considered to be due to variability in the newborn’s development or sleeping position, and therefore may be relieved to some extent by changing the newborn’s sleeping position, and if necessary, by seeking medical treatment. The inconsistency in the size of the two sides of the newborn’s face is considered to be due to the fact that the two sides of the face themselves are not completely symmetrical on the one hand, and on the other hand, it is considered to be caused by the newborn’s poor sleeping posture. When the size of the two sides of the newborn’s face is inconsistent, if it is due to the two sides of the face itself is not completely symmetrical, then there is no need to deal with; if it is caused by poor sleeping posture, you can adjust the newborn sleep on the side of the newborn in a timely manner to slowly correct the problem of asymmetry of the newborn’s face. In addition, should also rule out congenital cervical and other diseases caused by the inconsistency between the two sides, if found that the baby’s neck has a mass, the existence of neck tilted to the side of the deformity should be considered to consult the neonatal surgery for treatment. If the baby’s facial asymmetry has not been relieved, or accompanied by other symptoms, you should go to the hospital in time to clarify the cause of the targeted treatment.
