BACKGROUND Chordomas are primarily malignant tumors encountered at either end of the neural axis; the craniovertebral junction and the sacrococcygeal junction. In this article, we discuss the surgical management of craniovertebral junction chordomas. OBJECTIVE In this paper, we discuss the surgical management of craniovertebral junction chordomas. (More)
While substantial research has examined the control of information systems (IS) projects, most studies in this area have only examined how one controller manages a single group of controllees. However, many IS projects, especially enterprise systems projects (often initiated by an organization's corporate headquarters, and involving business unit users and(More)

Medical and surgical graduate medical education has historically used a halstedian approach of " see one, do one, teach one. " Increased public demand for safety, quality, and accountability in the setting of regulated resident work hours and limited resources is driving the development of innovative educational tools. The use of simulation in nonmedical,(More)
OBJECT The diagnosis of peripheral nerve lesions relies on clinical history, physical examination, electrodiagnostic studies, and radiography. Magnetic resonance neurography offers high-resolution visualization of structural peripheral nerve lesions. The availability of MR neurography may be limited, and the costs can be significant. By comparison,(More)

Objectives To determine the anatomical relationships that may influence endonasal access to the upper cervical spine. Setting We retrospectively analyzed computed tomography of 100 patients at a single institution. Participants Participants included adults with imaging of the hard palate, clivus, and cervical spine without evidence of fracture, severe(More)
Transsphenoidal microscopic pituitary surgery has long been considered the gold standard in surgical treatment of pituitary tumors. Endonasal endoscopic pituitary surgery has come into prominence over the last two decades as an alternative to microscopic surgery. In this review, we use recent literature to discuss the advantages and disadvantages of each(More)
BACKGROUND Despite the substantial impact of cavernous sinus invasion (CSI) in pituitary adenoma surgery, its radiologic determination has been inconsistent and variable, and the role of endonasal endoscopic surgery has been unclear. This is a systematic review and pooled data meta-analysis of the literature to ascertain the best radiologic criteria for CSI(More)
