OBJECT Routine and nonselective use of awake and outpatient craniotomy for supratentorial tumors has been shown to be safe and effective from a medical standpoint. In this study the authors aim was to explore patients' perceptions about awake and outpatient craniotomy. METHODS Qualitative research methodology was used. Two semistructured, open-ended(More)
OBJECT Advances in the neurosciences are stirring debate regarding the ethical issues surrounding novel neurosurgical interventions. The application of deep brain stimulation (DBS) for treating refractory psychiatric disease, for instance, has introduced the prospect of altering disorders of mind and behavior and the potential for neuroenhancement. The(More)
BACKGROUND There is no consensus on the best management of adults with presumed low grade glioma (LGG). Studies have suggested uncertainty and anxiety associated with a wait and see approach contribute to reduced quality of life. This study aims to explore the impact of a diagnosis of LGG, to address concerns regarding the uncertainty of the diagnosis and(More)
Objectives Postoperative hearing preservation rates for patients with large vestibular schwannomas range from 0 to 43%. The clinical and radiographic factors predicting hearing preservation in smaller vestibular schwannomas are well described; however, their importance in larger tumors is unclear. We investigated factors predicting hearing preservation in(More)
BACKGROUND CONTEXT Imaging modalities used to visualize spinal anatomy intraoperatively include X-ray studies, fluoroscopy, and computed tomography (CT). All of these emit ionizing radiation. PURPOSE Radiation emitted to the patient and the surgical team when performing surgeries using intraoperative CT-based spine navigation was compared. STUDY(More)
OBJECT The purpose of this case review was to identify and analyze existing wrong-site craniotomy (WSC) cases to determine the factors that contributed to the errors and to suggest preventative strategies for WSC. Wrong-site surgery (WSS) is a devastating surgical error that has gained increased public attention in recent years due to some high-profile(More)
BACKGROUND CONTEXT Pedicle screws are routinely used in contemporary spinal surgery. Screw misplacement may be asymptomatic but is also correlated with potential adverse events. Computer-assisted surgery (CAS) has been associated with improved screw placement accuracy rates. However, this technology has substantial acquisition and maintenance costs. Despite(More)
BACKGROUND Deep brain stimulation (DBS) for psychiatric indications is becoming increasingly safe and effective. As a result, the treatment of these conditions by neurosurgeons is becoming more widespread and a larger part of the functional neurosurgeons' practice. Given the troubled history of the field and its current renaissance, it is important to(More)
BACKGROUND Interest in neurosurgery for psychiatric diseases (NPD) has grown globally. We previously reported the results of a survey of North American functional neurosurgeons that evaluated general attitudes towards NPD and the future directions of the field. OBJECTIVES The purpose of this study was to expand on our previous work and obtain a snapshot(More)
In January of 2011 I, together with my fourth-year medical student colleagues, returned to the University of Western Ontario from our electives to begin four months of preparation for our medical licensing exam. During large group discussions on general clinical scenarios, it was clear that, for most students, specialization was well underway. When listing(More)
