Abstract
Objective Closed-suction drains are commonly placed after thoracolumbar surgery to reduce the risk of post-operative hematoma and neurologic deterioration, and may stay in place for a longer period of time if output remains high. Prolonged maintenance of surgical site drains, however, is associated with an increased risk of surgical site infection (SSI). The present study aims to examine the literature regarding extended duration (≥24 h) prophylactic antibiotic use in patients undergoing posterior thoracolumbar surgery with closed-suction drainage. Methods This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Relevant studies reporting the use of 24-h post-operative antibiotics compared with extended duration post-operative antibiotics in patients undergoing posterior thoracolumbar surgery with closed-suction drainage were identified from a PubMed database query. Results Six studies were included for statistical analysis, encompassing 1003 patients that received 24 h of post-operative antibiotics and 984 patients that received ≥24 h of post-operative antibiotics. The SSI rate was 5.16 % for the shorter duration group (24 h) and 4.44 % (p = 0.7865) for the longer duration group (≥24 h). Conclusions There is no significant difference in rates of SSI in patients receiving 24 h of post-operative antibiotics compared with patients receiving ≥24 h of post-operative antibiotics. Shorter durations of post-operative antibiotics in patients with thoracolumbar drains have similar outcomes compared to patients receiving longer courses of antibiotics. Shorter durations of antibiotics could potentially help lead to lower overall cost and length of stay for these patients.

Abstract
There are several surgical approaches for vestibular schwannoma (VS) resection. However, management has gradually shifted from microsurgical resection, toward surveillance and radiosurgery. One of the arguments against microsurgery via the middle fossa approach (MFA) is the risk of temporal lobe retraction injury or sequelae. Here, we sought to evaluate the incidence of temporal lobe retraction injury or sequela from a MFA via a systematic review of the existing literature. This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Relevant studies reporting temporal lobe injury or sequela during MFA for VS were identified. Data was aggregated and subsequently analyzed to evaluate the incidence of temporal lobe injury. 22 studies were included for statistical analysis, encompassing 1522 patients that underwent VS resection via MFA. The overall rate of temporal lobe sequelae from this approach was 0.7%. The rate of CSF leak was 5.9%. The rate of wound infection was 0.6%. Meningitis occurred in 1.6% of patients. With the MFA, 92% of patients had good facial outcomes, and 54.9% had hearing preservation. Our series and literature review support that temporal lobe retraction injury or sequelae is an infrequent complication from an MFA for intracanalicular VS resection.

Abstract
OBJECTIVE The process surrounding application to the national residency matching program changed drastically because of COVID. Virtual interviews, pre-interview zoom socials, and limitations on sub-internships are major changes that applicants worldwide have had to overcome. The available literature does not reflect the impact of major changes to the interview process. Here, we examine the neurosurgery resident cohort from 2021-2023 to investigate differences between United States medical schools pre- and post-COVID. METHODS A database was constructed reporting the number of students matched to neurosurgery for U.S. medical schools (MD and DO) from 2021-2023. Percentage of total graduates matched to neurosurgery was calculated and institutions were ranked by this metric. This rank was compared to the rank reported by Antar et al in 2021. Variables were compared across the pre- and post-COVID cohorts. RESULTS Case Western, Johns Hopkins, Mayo Clinic, Vanderbilt, University of Illinois and University of California San Francisco produced the most neurosurgical residents as a percentage of total graduates. There was a statistically significant difference in the post-COVID cohort between medical schools with a home program vs those without. For the top 20 ranked U.S. News medical schools, there was a statistically insignificant increase in the number of graduates matched to neurosurgery CONCLUSIONS: With the data provided, there have not been many significant changes in which medical schools produce the most neurosurgery residents since COVID changes were implemented. The playing field has remained relatively the same in the setting of major changes that were made.

Endoscopic third ventriculostomy in hydrocephalus patients with functioning ventriculoperitoneal shunts: challenging the dictum that shunts treat all types of hydrocephalus. Patient series.

Abstract
BACKGROUND Although ventriculoperitoneal shunting is standard for hydrocephalus, shunting may not be ideal for aqueductal stenosis. A cohort of patients with aqueductal stenosis displayed symptoms of over- and underdrainage, despite a patent ventriculoperitoneal shunt (VPS) and optimized valve settings. Endoscopic third ventriculostomies (ETVs) were performed in a subset of these patients with successful treatment of their underlying hydrocephalus, despite a functioning shunt. OBSERVATIONS All patients who had undergone ETV with a history of ventriculoperitoneal shunting were retrospectively reviewed. Patients experiencing over- or underdrainage symptoms despite a patent shunt were included. Cerebral aqueduct anatomy and third ventricle bowing were reviewed on preoperative imaging. Seven patients met the study criteria. All showed cerebral aqueductal stenosis and third ventricle bowing. After ETV, all patients demonstrated decreased third ventricle bowing and clinical improvement without the need for secondary cerebrospinal fluid (CSF) diversion. LESSONS Despite a functioning VPS, patients with aqueductal stenosis may not be adequately treated. The underlying reasons are not clearly understood but suggest abnormal CSF dynamics due to aberrant parenchymal compliance. The authors theorize that ETV can more effectively treat these patients. ETV can be considered a viable treatment option in aqueductal stenosis despite a patent VPS, challenging the traditional teaching that shunts ideally treat all types of hydrocephalus.

Abstract
OBJECTIVE A major critique of the h-index is that it may be inflated by noncritical authorship. We propose a modified h-index (hm), incorporating critical authorship, complementary to the h-index. We analyze its relationship to the traditional h-index, and how each varies across professional categories relevant to academic neurosurgery. This analysis is not meant to critique authorship decisions, affect career development, alter academic legacy, or imply that the concepts of team science or midlevel authorship contributions are not valuable. METHODS H-indices and hms were gathered and computed for clinical neurosurgical faculty at the top 32 ranked academic neurosurgical programs based on the current literature. Hm was computed for faculty at each program, using articles in which the individual was first, second, last, or co-corresponding author. Individuals were further identified based on chair status, leadership status, neurosurgical subspecialty, and National Institutes of Health funding status. Further analysis was performed to determine factors influencing h-index and hm. RESULTS The median h-index for the 225 physicians included in the final dataset is 48 (interquartile range [IQR], 39-61), whereas the median hm was 32 (IQR, 24-43). The median difference between h-index and hm is 15 (IQR, 10-23). The median hm/h was 64% (IQR, 57-74). National Institutes of Health funding and subspecialty (neurosurgical oncology, neurocritical care, and cerebrovascular) were associated with significant change from h to hm. CONCLUSIONS The h-index can be influenced by noncritical authorship, and hm, using critical contributions, can be used as a complement reflecting critical academic output in neurosurgery. Leaders deciding on hiring or promotion should consider disparities in productivity predicated on noncritical authorship contributions.

Abstract
Many strides have been made in neurosurgery during times of war, helping to improve the outcomes of patients in dire circumstances. World War I introduced the concepts of early operation for trauma, forward-operating hospitals, and galeal sutures as well as techniques for careful debridement. It laid the groundwork for neurosurgery to become a specialty within medicine as well. World War II brought about the use of expedited medical evacuation, mobile neurosurgical units, improved resuscitation strategies, cranioplasty, and early laminectomy with decompression. The Korean and Vietnam Wars built on concepts from World Wars I and II, helping to establish the importance of watertight dural closure, external drainage systems after cranial trauma, multidisciplinary care, and infection prevention strategies. In the post-Vietnam period, we have seen significant technological advances allowing neurosurgeons to move farther ahead than most throughout history could have imagined. The significance of secondary brain injury, vascular injury, and the underlying pathophysiology of traumatic insults has been elucidated over the years since the Vietnam War, allowing for great advances in the care of our patients. Each major war throughout history has contributed greatly to the specialty of neurosurgery, each with its own innovations culminating in guidelines, strategies, and standards of practice that allow us to deliver the highest standard of care to our patients.

Abstract
Thoracolumbar fractures are a common consequence of trauma, often a result of motor vehicle accidents or falls. Burst fractures are a morphology of thoracolumbar fracture in which compressive force causes retropulsion of the posterior elements of the vertebral body, potentially leading to neurological deficits. The Thoracolumbar Injury Classification and Severity (TLICS) score is a decision-making tool to help surgeons decide between nonoperative and operative management. For assigned scores of 4, management is at the discretion of the surgeon, and for scores ≥ 5, operative treatment is recommended. Burst fracture patients that are neurologically intact are given a score of 5 if there is a posterior ligamentous complex (PLC) injury and are recommended to undergo operative management. Here we present a neurologically intact patient with an L4 burst fracture with PLC injury that was managed conservatively and demonstrated successful clinical, functional, and radiographic recovery.
