AbstractShaving of the whole scalp is ordinarily performed prior to neurosurgical operation. Although it is performed in order to prevent postoperative intracranial infection, there has been no apparent basis for this practice published in previous reports. We examined whether shaving the whole scalp reduced the rate of postoperative infection or not. We divided 274 cases, who received their first intracranial operation in the last 2 years, into two groups; a whole shaving group and a partial shaving group. We compared the rate of postoperative intracranial infection between the two groups according to age, diagnosis, operation, operation time and placement of drainage. Overall, 12 cases out of 274 (4.38%) had postoperative intracranial infection. The long operation time and the long term placement of drainage mechanism increased the postoperative intracranial infection rate. There was no postoperative intracranial infection in 74 patients who received burr-hole/twist-drill operation. As for craniotomy/craniectomy operations, 7 cases out of 83 (8.4%) in the partial scalp-shaving group whole scalp shaving group and 5 cases out of 117 (4.2%) had postoperative intracranial infections. Thus, there was no significant difference in the rate of postoperative intracranial infection between the two groups, if anything, the whole scalp shaving group tended to show a higher rate. According to these results, partial scalp shaving did not increase the rate of postoperative intracranial infection. Considering that patients who have lost their hair find it embarrassing to return to society, it is well to know that the whole scalp shaving is not absolutely necessary for all first craniotomy.
