The neurosurgery service at the Medical College of Georgia (MCG), Georgia Regents University Augusta (GRU) has a rich history spanning almost six decades. We review the development of neurological surgery as a specialty in Augusta, Georgia and the history of the department of neurosurgery at GRU. This article describes some of the early neurosurgeons in the city and those that have helped to contribute to the field and shape the department. Our functional and stereotactic program is emphasized. Our surgical epilepsy program dates back over half a century and remains a highly experienced program. We also describe our affiliation with the medical illustration graduate program, which was the first to be accredited and remains one of four such programs in the world. Finally, we list our alumni, former faculty, and current faculty, as well as the major accomplishments in our first decade as a full department.

Background: During awake craniotomies, patients may either be awake for the entire duration of the surgical intervention (awake-awake-awake craniotomy, AAA) or initially sedated (asleep-awake-asleep craniotomy, SAS).
Objective: To examine whether prior sedation in SAS may restrict brain mapping, we conducted neuropsychological tests in patients by means of a standardized anesthetic regimen comparable to an SAS.
Methods: We prospectively examined patients undergoing surgery either under total intravenous anesthesia (TIVA) or under regional anesthesia with slight sedation (RAS). The tests included the DO40 picture-naming test, the digit span, the Regensburg Word Fluency Test, and the finger-tapping test. Each test was conducted 3 times for every patient in the TIVA and RAS groups, once before surgery and twice within about 35 minutes after the end of sedation. Patients undergoing AAA were examined preoperatively and intraoperatively.
Reliable delivery of optimal care can be challenging for care providers. Health care leaders have integrated various business tools to assist them and their teams in ensuring consistent delivery of safe and top-quality care. The cornerstone to all quality improvement strategies is the detailed understanding of the current state of a process, captured by process mapping. Process mapping empowers caregivers to audit how they are currently delivering care to subsequently strategically plan improvement initiatives. As a community, neurosurgery has clearly shown dedication to enhancing patient safety and delivering quality care. A care redesign strategy named NERVS (Neurosurgery Enhanced Recovery after surgery, Value, and Safety) is currently being developed and piloted within our department. Through this initiative, a multidisciplinary team led by a clinician neurosurgeon has process mapped the way care is currently being delivered throughout the entire episode of care. Neurosurgeons are becoming leaders in quality programs, and their education on the quality improvement strategies and tools is essential.
Recent research in brain imaging has highlighted the role of different neural networks in the resting state (ie, no task) in which the brain displays spontaneous low-frequency neuronal oscillations. These can be indirectly measured with resting-state functional magnetic resonance imaging, and functional connectivity can be inferred as the spatiotemporal correlations of this signal. This technique has proliferated in recent years and has allowed the noninvasive investigation of large-scale, distributed functional networks. In this review, we give a brief overview of resting-state networks and examine the use of resting-state functional magnetic resonance imaging in neurosurgical contexts, specifically with respect to neurooncology, epilepsy surgery, and deep brain stimulation. We discuss the advantages and disadvantages compared with task-based functional magnetic resonance imaging, the limitations of resting-state functional magnetic resonance imaging, and the emerging directions of this relatively new technology.

Increasingly, hospitals and physicians are becoming acquainted with business intelligence strategies and tools to improve quality of care. In 2007, the University of California Los Angeles (UCLA) Neurosurgery Department created a quality dashboard to help manage process measures and outcomes and ultimately enhance clinical performance and patient care. At that time, the dashboard was in a platform that required data to be entered manually. It was then reviewed monthly to allow the department to make informed decisions. In 2009, the Department leadership worked with the UCLA Medical Center to align mutual quality improvement priorities. The content of the dashboard was redesigned to include three areas of priorities: quality and safety, patient satisfaction, as well as efficiency and utilization. Throughout time, the Neurosurgery quality dashboard has been recognized for its clarity and its success in helping management direct improvement strategies and monitor impact.

Background: A virtual reality (VR) neurosurgical simulator with haptic feedback may provide the best model for training and perfecting surgical techniques for transsphenoidal approaches to the sella turcica and cranial base. Currently there are 2 commercially available simulators: NeuroTouch (Cranio and Endo) developed by the National Research Council of Canada in collaboration with surgeons at teaching hospitals in Canada, and the Immersive Touch. Work in progress on other simulators at additional institutions is currently unpublished.
Objective: This article describes a newly developed application of the NeuroTouch simulator that facilitates the performance and assessment of technical skills for endoscopic endonasal transsphenoidal surgical procedures as well as plans for collecting metrics during its early use.
Methods: The main components of the NeuroTouch-Endo VR neurosurgical simulator are a stereovision system, bimanual haptic tool manipulators, and high-end computers. The software engine continues to evolve, allowing additional surgical tasks to be performed in the VR environment. Device utility for efficient practice and performance metrics continue to be developed by its originators in collaboration with neurosurgeons at several teaching hospitals in the United States. Training tasks are being developed for teaching 1- and 2-nostril endonasal transsphenoidal approaches. Practice sessions benefit from anatomic labeling of normal structures along the surgical approach and inclusion (for avoidance) of critical structures, such as the internal carotid arteries and optic nerves.
