Question
The 21-month-old baby’s fontanelle was pressed several times by the cross-shaped tip of an earphone. The earphone’s cross-shaped tip is hard and sharp, and the pressed area of the baby’s fontanelle is red, with a small indentation where the tip was pressed.
Answer
First, let’s introduce some basic knowledge about fontanels: when checking an infant’s fontanelle, use the pad of your index finger to gently touch it up and down. Normally, the fontanelle should be flat or slightly concave. Swelling may indicate increased intracranial pressure, while dehydration might cause indentation. The development of the fontanelle is related to intelligence, and since this baby’s fontanelle was affected by external force, it is recommended to seek medical attention immediately. Additionally, generally, fontanels should close between 12 and 18 months of age.
