Question
A 4-month-old baby accidentally fell on the evening of November 20th and struck the head, resulting in a concave fracture of the parietal bone about 5 millimeters above the right ear with an area of approximately 3cm x 4cm and a depth of about 0.5cm. The CT scan showed no intracranial injury or hematoma. The hospital diagnosed it as a concave fracture of the skull. After nearly two weeks of observation, the baby did not exhibit any abnormal symptoms. What should be done in this situation?
