Microcephaly, also known as microcephaly, is called cephalic microcephaly. The main manifestations of this condition are a significantly lighter-than-normal brain weight after the completion of brain development, small or no brain gyrus at all, and a significantly delayed brain development. The development of the brain stops even in the third to fifth month of infancy. As a result, the top of the child’s head becomes small and pointed, with a sunken nose, large ears, a retracted jaw, a narrow forehead, and an extraordinarily small head circumference, with the largest being less than 42 centimeters. The infant’s forehead and occipital region are flat, the fontanels and bone seams close early, and the physical development is markedly abnormal and accompanied by a significant delay in mental development. Seizures may be present, as well as rigidity of the limbs, hypertonia and bradykinesia, and paralysis. If there is increased intracranial pressure, surgery should be performed as soon as possible after the diagnosis is confirmed by CT and radiographs. For those who simply have premature closure of the bone sutures, surgery can be used to reopen the sutures, which can improve the situation.
