Oblique lumbar interbody fusion (OLIF) through the oblique corridor between the aorta and anterior border of psoas muscle is favored among spinal surgeons who employ minimally invasive techniques. We report a case of ventral dural tear after OLIF that was associated with the inaccurate trajectory direction of endplate preparation. This is the first report to our knowledge of ventral dural tear associated with OLIF. ⋯ When a surgeon performs OLIF, ventral dural injury should be avoided during the procedure of endplate preparation and contralateral annular release.

An extensive frontal resection is a frequently performed neurosurgical procedure, especially for treating brain tumor and refractory epilepsy. However, there is a paucity of reports available regarding its surgical anatomy and technique. ⋯ FLD is an anatomy-based surgical technique for extensive frontal lobe resection. It presents reliable anatomic landmarks, selective gray matter removal, preservation of frontal horn, and low complication rate in our series. It can be an alternative option to the classical frontal lobectomy.

Spinal arteriovenous malformations (AVMs) are rare lesions that may cause serious neurologic morbidity. With developments in endovascular technology and embolic materials, endovascular management of spinal AVMs has gained popularity. ⋯ Spinal AVMs manifesting as intracranial SAH are uncommon. These lesions are frequently overlooked on cerebral angiography and account for a small proportion of angiogram-negative SAHs. A negative angiogram in the setting of SAH should prompt a comprehensive evaluation of the cervical segmental arterial supply to exclude a cervical spinal AVM. Endovascular embolization may be effective in treating spinal glomus AVMs with good clinical outcomes and with complete angiographic obliteration. Onyx embolic agent should be considered as the agent of choice to manage spinal glomus AVMs.

The Use of Google Glass to Enhance the Surgical Education of Neurosurgery Residents: A "Proof-of-Concept" Study.
The relatively decreased time spent in the operating room and overall reduction in cases performed by neurosurgical trainees as a result of duty-hour restrictions demands that the pedagogical content within each surgical encounter be maximized and crafted toward the specific talents and shortcomings of the individual. It is imperative to future generations that the quality of training adapts to the changing administrative infrastructures and compensates for anything that may compromise the technical abilities of trainees. Neurosurgeons in teaching hospitals continue to experiment with various emerging technologies-such as simulators and virtual presence-to supplement and improve surgical training. ⋯ While Google Glass harbors the potential to dramatically improve both neurosurgical education and practice in a variety of ways, certain technical drawbacks of the current model limit its effectiveness as a teaching tool.

The relationship between the use of an endoscope during ventriculoperitoneal shunt (VPS) procedures and infection remains poorly defined. In this study, we sought to analyze whether the simultaneous use of an endoscope could in fact increase the infection rate associated with VPS procedures. ⋯ In the present study, the use of an endoscope during VPS procedures did not increase the risk of surgical infection.
