Infants with sunken temples on both sides are considered to be related to genetic factors, infant wasting and abnormal skull development. 1. Genetic factors: some infants will have sunken temples after birth due to family genetic reasons, but there is no other discomfort. 2. Infant wasting: It may be due to improper feeding or the infant’s own physical reasons, resulting in excessive wasting and reduction of subcutaneous fat, which often leads to sunken temples, and other parts of the body may also be sunken. 3. Abnormal skull development: it may be congenital defects in the baby’s skull area, resulting in concave on both sides, but the degree of concavity is often not the same. Infants with sunken temples on both sides, if there are no other uncomfortable symptoms, usually do not need treatment, but if accompanied by discomfort, promptly go to the hospital.
