The effect of hair on infection after cranial surgery.
OBJECTIVE
Reports of large series of patients who had undergone successful cranial neurosurgery without hair removal led part of our team to abandon the practice of shaving patients' heads pre-operatively. The aim of this study was to assess whether this change in routine, which was implemented in 1992, has affected the rate of postoperative infection in our cranial surgery patients.


METHODS
A group of patients whose heads were shaved pre-operatively was compared to a group whose hair was not shaved prior to cranial surgery. The latter patients had their hair washed with shampoo and 4% chlorhexidine within 24 hours of their operation. In the operating room, the surgical site was scrubbed for 8-10 minutes with 4% chlorhexidine diluted with water, and then cleansed with 10% povidone-iodine solution. Prophylactic antibiotics were administered for 3 days.


RESULTS
We performed 1,038 cranial procedures without hair removal. The procedures included craniotomy for tumour, trauma, aneurysm, other vascular lesions and intracerebral haemorrhage (n = 847), stereotactic biopsy (n = 90), stereotactic craniotomy (n = 34), ventriculoperitoneal shunt placement (n = 27), surgical treatment of infection with aspiration of brain abscess or resection of infected tissue (n = 14), microvascular decompression for trigeminal neuralgia or hemifacial spasm (n = 11), and other miscellaneous procedures (n = 15). We observed 13 postoperative wound infections (1.25%), including 9 deep (0.87%) and 4 superficial infections (0.39%). There was no significant difference between the rate of infection in patients whose heads were shaven (12/980) and the rate in those whose hair was spared (13/1038) (p > 0.05). In addition. there were no other problems related to the surgical preparation technique in the latter group.


CONCLUSIONS
Cranial surgery without hair removal is safe and does not increase the risk of surgical wound infection. Patients naturally prefer to keep their full head of hair. We believe that preoperative hair removal is not necessary in preparation for any type of cranial neurosurgery.
