A seven years follow up study bas been made on the expanding craniotomy for the infants and children with craniostentic and/or microcephalic state. The new operative techniques, "expanding craniotomy" was brought foreward by Hon et al in 1965. In this method, several metalic springs are inserted into the groove made by linear craniotomy. The number of these springs is decided on the basis of E. E. G. findings. As shown in the table 1 and 2, the two third of all cases show satisfactory improvements. The most important thing through these results is that improvements are seen even in cases with mental and motor maldevvelopment after the surgery. A five years follow up study of the expanding craniotomy revealed that this kind of surgery is effective for epileptic seizures (33%), spastic paralysis (21%) and stridor (9%). Stress is to be given to the improvements for the disturbances of autonomic nervous system, such as appetite, countenance, color and texture of skin, sweating, salivation, emotion and body supporting. Comments： 1. Effects for the epileptic attack, nodding spasm and spasticity of extremities are to be shown one or two months after expanding craniotomy. The longer the time goes by after the surgery, the more the pleasant changes increase.
