Simulation models enable trainees to master microsurgical skills before performing surgeries. Vascular bypass is a critical component of cerebrovascular and many nonneurologic procedures. However, most available bypass training models lack important spatial, tactile, and physiologic aspects of real surgery. Animal and placental models provide true physiology but are expensive. While some models adequately simulate superficial temporal artery-middle cerebral artery bypass, there is no model for side-to-side distal anterior cerebral artery bypass. The objective is to create a realistic and inexpensive training model for this important procedure. ⋯ This grapefruit model provides a realistic simulation of side-to-side distal anterior cerebral artery bypass procedure that can be inexpensively and easily implemented in nearly any resource environment.

Brain metastases from prostate cancer are rare and poorly described. We sought to assess the proportion of brain metastases arising from prostate cancer and to detail clinical characteristics, treatment modalities, and survival outcomes. ⋯ Brain metastasis from prostate cancer constitutes a small fraction of total brain metastases, but is associated with poor prognosis and is seen in the setting of advanced, castrate resistant disease. These data enable treating physicians to appropriately counsel their patients with prostate adenocarcinoma brain metastasis.

Neurosurgical training usually requires long hours for hands-on procedures, making it difficult for inexperienced surgeons to quickly learn in an error-proof environment. The objective of this study was to propose a puzzle-like new model for neurosurgical education that simulates craniosynostosis correction (scaphocephaly type) using Renier's H technique. A model of a 3-dimensional (3D) anatomic simulator for craniosynostosis training is presented and evaluated. ⋯ The puzzle may be a complementary tool for surgical training. It allows several degrees of immersion and realism, offering symbolic, geometric, and dynamic information with 3D visualization. It provides additional data to support the practice of complex surgical procedures without exposing real patients to undue risk.

Case Reports
Cranial Vault Reconstruction and Evacuation of Hemorrhage Following a Bifrontal Gunshot Wound to the Brain.
Civilian gunshot wounds to the brain are associated with high overall mortality; however, outcomes can vary significantly depending on bullet trajectory. This report details the outcome of a patient who sustained a bifrontal gunshot wound with multiple associated calvarial and frontal sinus fractures. Although surgery for penetrating brain injury is most frequently employed for relief of mass effect and decompression of vital structures, this case report describes a more comprehensive technique involving duroplasty, obliteration of the frontal sinus, and cranial vault reconstruction with the aim of decreasing the rate of cerebrospinal fluid leak, infection, reoperation, and readmission.
