ObjectiveIn an effort to improve patient confidentiality as well as cosmesis, the authors have stopped shaving for all intracranial procedures. The objective was to determine whether this lack of shaving increased the postoperative infection rate.DesignA retrospective study was performed comparing all intracranial surgical procedures performed in the last 2½ years, when hair was not shaved, with the infection rate in patients who did have their hair shaved in the preceding 3½ years.SettingAn academic tertiary care referral center.PatientsEvery patient (children and adults) who underwent an intracranial procedure by the skull base surgery team was included. Similar patient demographics were used for the hair-shaved group.Intervention(s)Intracranial procedures consisted of acoustic tumor removal, vestibular nerve sections, skull base surgery procedures, vascular decompressions, and craniotomies for benign and malignant tumors.Main Outcome MeasuresThe most essential criterion was to determine whether postoperative wound infection developed in a patient. This was documented as either minor (stitch abscess or wound dehiscence), moderate (wound breakdown requiring inpatient or outpatient therapy, such as oral or intravenous antibiotics), or severe (significant wound breakdown that required hospitalization, with surgical debridement and antibiotics).ResultsIn all, 150 patients were not shaved for their intracranial procedures; postoperative wound infections developed in 11 (7%). The infections were minor(6), moderate(5), and severe (0). By comparison, 100 patients undergoing intracranial procedures had their hair shaved. In this group, the number of infections noted was 6 (6%). Their categorization into mild, moderate, and severe was 4, 2, and 0, respectively. Statistical analysis did not reveal any significant difference between the two infection rates.ConclusionsThe rate of postoperative wound infection was statistically no greater when the hair was shaved than when it was not. Thus, for patient confidentiality as well as patient esteem, we recommend not shaving hair for intracranial procedures.
