Intraoperative multimodal neuromonitoring (IONM) is considered valuable for the early detection and prevention of any neurologic compromise during spine surgery. It has also become the standard of care at many institutions to improve the surgical outcome and be a safety net for both clinical and medicolegal concerns. ⋯ Despite our analysis proving no difference in clinical outcomes with or without the use of IONM during surgical excision of lumbar schwannomas, we still prefer using IONM as a standard approach. It adds to the confidence and ease of mind of the surgeon during resection and also provides valuable data in cases of medicolegal disputes. However, it comes with an increased cost and lengthened surgical procedure.

The Intracranial and Intracanalicular Optic Nerve as Seen Through Different Surgical Windows: Endoscopic Versus Transcranial.
Surgically manageable lesions involving the intracranial or intracanalicular portions of the optic nerve (cranial nerve II) can be approached through several different operative windows. Given the complex anatomy of the optic nerve and its surrounding neurovascular structures, it is essential to understand the conventional and topographic anatomy of the optic nerve from different surgical perspectives as well as its relationship with surrounding structures. We describe the intracranial and intracanalicular course of the optic nerve and present an analytical evaluation of the degree of exposure provided by several different transcranial and endoscopic surgical approaches. ⋯ Although the pterional approach provides the widest degree of surgical exposure of all optic nerve segments, the inferior and medial quadrants of the nerve can be adequately exposed only through an endoscopic endonasal approach. Optimal approach selection based on the intended target quadrant is essential for safe surgical exposure of the optic nerve.

The aim of this study is to detail the background, training, and career of Dr. Georgette Kidess, the first and still the only female neurosurgeon in Palestine. In addition, we mention the obstacles that women face during their neurosurgical career and how to overcome them. Also, we discuss different methods to attract female medical students to neurosurgery. ⋯ In this article, we recount Dr. Kidess's contributions and achievements to neurosurgery in Palestine. Her commitment, persistence, and diligence enabled her to overcome great odds and become the first female neurosurgeon in Palestine. We hope that her story will inspire and open the doors for subsequent women to enter and enhance neurosurgery, especially in the Middle East.

In view of the few large prospective studies available on the role of preoperative diffusion tensor imaging (DTI), and the potential of DTI in showing the relationship between tumor and white matter tracts, we studied the role of preoperative DTI in planning a safe surgical corridor, predicting the neurologic and surgical outcome and tumor characterization in supratentorial intra-axial brain tumors. ⋯ Preoperative DTI is a landmark tool for planning a safe surgical corridor and predicting the tumor type along with neurologic and surgical outcome of patients.

It is difficult to completely comprehend the anatomy of the structures surrounding the paraclinoid region before aneurysm and tumor treatment therein. When treating paraclinoid aneurysms, it is important to determine the location of the aneurysm as intradural or extradural. Thus, accurate prediction of the position of the distal dural ring (DDR) is necessary. To this end, we focused on the falciform ligament (FL), which is easily visualized on images based on its anatomic features. We measured the distance between the FL and the DDR in patients undergoing paraclinoid aneurysm operations. ⋯ The position of the FL can be easily predicted using preoperative three-dimensional computed tomography angiography based on its anatomic features. In this study, the DDR was located 3.5 mm proximal to the FL along the internal carotid artery. This information is useful for predicting the position of the DDR.
