Patients undergoing pituitary adenoma or Rathke cleft cyst (RCC) removal are often administered perioperative glucocorticoids regardless of lesion size and preoperative adrenocorticotropic hormone/cortisol levels. To minimize unnecessary glucocorticoid therapy, we describe a protocol in which patients with normal preoperative serum cortisol and adrenocorticotropic hormone levels are given glucocorticoids only if postoperative day 1 or 2 (POD1 or POD2) cortisol levels decrease below normal. ⋯ In patients with normal preoperative cortisol levels undergoing endonasal removal of a pituitary adenoma or RCC, normal morning cortisol values on POD1 and POD2 reliably predicts adequate and safe adrenal function in 98% of patients. This simple protocol of withholding postoperative glucocorticoids avoids unnecessary steroid exposure and poses minimal risk to the well-informed closely monitored patient.

Chronic subdural hematoma (CSDH) after aneurysmal clipping is a rare complication, but its incidence and risk factors are not known in detail. We retrospectively reviewed our cases requiring surgery for CSDH after clipping. ⋯ In addition to the classic risk factors, this study showed that clipping for unruptured aneurysms carries a higher risk for CSDH compared to ruptured aneurysms. We suggest that an increase of SFC during 1 week postoperatively can be a factor in predicting CSDH after clipping.

Traumatic spondylolisthesis of the axis, also known as a hangman's fracture, is a well-described entity but is relatively uncommon. There are only two published reports of these fractures occurring in pediatric patients with osteogenesis imperfecta, a disorder that predisposes patients to long bone fractures. ⋯ Effendi type II fractures can be conservatively managed via rigid or nonrigid cervical orthosis.

Endoscopy has provided a less invasive approach to skull base surgery, mainly through endonasal routes, but has been limited in its applications due to potential complications. The aims of this study were to evaluate the feasibility of the purely endoscopic extradural transcranial approach to lateral and central skull base through a subtemporal keyhole and to better understand potential distortions of the related anatomy via endoscopy. ⋯ The endoscopic extradural subtemporal approach was feasible. This approach could display a wide range of lateral and central skull base structures with minimal invasiveness. The use of extradural space would be key to performing safe and effective endoscopic skull base surgery.

Introduction of a book and cinema club in a Department of Neurosurgery has helped combine an education in humanities with neurosurgical training. The authors believe the addition of teaching in humanities adds to the specialty and helps in fulfilling the six core competencies of the Accreditation Council for Graduate Medical Education. The goal is to encourage synoptic philosophy and impart creative ways of interacting with the world. ⋯ Of residents, 61.5% believed the topics were pertinent to their everyday life, and 77% believed that the club had helped them somehow in residency. Most (7 of 13) believed the club should not be included as part of the curriculum in an 80-hour work week. Institution of a book and movie club seems to be an effective way of integrating humanities within a neurosurgical residency.
