Topic review articles have become increasingly popular, even as the neurosurgical community looks to peer-reviewed journals as a source of discovery in basic and clinical science. In this study we quantify the prevalence of topic review articles in top neurosurgery journals. ⋯ The increasing prevalence of topic reviews is seen in most neurosurgery journals, reflecting supply and demand. Although there are benefits to these articles, they do not contribute novel data. Actions such as defining and labeling this publication type in journals and databases will improve the transparency of research methods. Academic neurosurgeons should further expand their knowledge and not become focused only on introspection into and review of neurosurgical understanding and practice.

Review Case Reports
Pre-incisional Localization: An Overlooked Contribution by Ralph Bingham Cloward.
Preincisional localization has become ubiquitous within spinal neurosurgery and has served as the foundation for modern minimally invasive surgery techniques. Dr. ⋯ In his landmark 1958 article on what is now known as anterior cervical diskectomy and fusion, Cloward commented on a case of wrong-level surgery that motivated him to implement a standardized technique for spinal level localization with the patient under anesthesia in the operating room before skin incision. We trace the origins of the use of preincisional radiographs to localize the pathologic level at the time of diskectomy and highlight this original contribution by Cloward.

Cordotomy is a viable option for patients with intractable cancer pain and limited survival. Open thoracic cordotomy is offered when patients are not candidates for percutaneous cordotomy. After the open procedure, traditionally performed purely based on anatomic landmarks, up to 22% of patients experience postoperative limb weakness. The objective of this study is to report our experience with neurophysiology-guided open cordotomy along with a critical review of the literature. ⋯ Open thoracic cordotomy is a safe and effective procedure for intractable cancer-related pain. Technical advancements significantly reduced mortality and major morbidity of PCC. Our series suggests that neurophysiology monitoring alters the location of the lesion and may help better targeting of pain fibers within the spinothalamic tract and preserve other long tracts. The safety profile of open cordotomy with neurophysiology compares favorably with the PCC.

The pterional craniotomy is a workhorse of cranial surgery that provides access to the anterior and middle fossae. However, newer "keyhole" approaches, such as the micropterional or pterional keyhole craniotomy (PKC) can offer similar exposure for many pathologies while reducing surgical morbidity. ⋯ Furthermore, it represents an ongoing trend toward smaller craniotomy size for elective cranial procedures. In this historical vignette, we trace the history of the PKC from its origins to its current role in the neurosurgeon's armamentarium.

Endoscopic surgery is adopted as a minimally invasive technique in several surgical fields. Endoscopic spine surgery (ESS) was performed initially for lumbar discectomy but is currently widely utilized for various pathologies. ⋯ Intraoperative computed tomography enables the use of an image-guided navigation system in ESS, which is a suitable approach for managing complex lesions. Full-ESS is currently being adopted for certain cervical pathologies, and the incorporation of an image-guided navigation system will soon enable surgery for other cervical pathologies.
