Abstract	Since our last Special Annual Issue dedicated to the topic of ependymoma in 2009, critical advancements have been made in the understanding of this disease which is largely confined to childhood. In the era of molecular profiling, the prior classification of ependymoma based on histology has become largely irrelevant, with multiple new subtypes of this disease now being described in the newest 2021 WHO CNS Tumor Classification System. Despite our advancements in understanding the underlying biology of these tumors, the mainstays of treatment-gross total surgical resection followed by confocal radiation therapy-have continued to yield the best treatment results across multiple studies and centers. Here, we provide an update on our understanding of the advancements made in tumor biology, surgical, and oncologic management of this disease. As we move into an era of more personalized medicine, it is critical to reflect on our historical understanding of different disease entities, to better understand the future directions of our treatments.

Abstract	The authors describe the unusual case of a 6-year-old boy presenting with decorticate posturing, diminished hearing, and an inability to open his eyes, despite being verbally responsive. He underwent a posterior interhemispheric transcallosal intervenous approach for resection of a pineal region mature teratoma, which recurred 2 years postoperatively. This video demonstrates his initial surgery and reresection, illustrating the value of this approach for more complex lesions that involve the internal cerebral veins (ICVs). At the time of recurrence, microsurgical dissection of the scarred interhemispheric fissure was required to facilitate removal of the multifocal recurrent teratoma, resulting in gross-total resection. The video can be found here: https://stream.cadmore.media/r10.3171/2021.4.FOCVID2134.

Abstract	Purpose: Pediatric-type diffuse high-grade gliomas are the leading cause of cancer-related morbidity and mortality in children. More than 30% of diffuse hemispheric gliomas (DHG) in adolescents harbor histone H3 G34 mutations and are recognized by the World Health Organization as a distinct tumor entity. By reporting bibliometric characteristics of the most cited publications on H3 G34-mutant DHG (H3 G34 DHG), we provide an overview of emerging literature and speculate where future research efforts may lead. Methods: One hundred fourteen publications discussing H3 G34 DHG were identified, categorized as basic science (BSc), clinical (CL), or review (R), and ranked by citation number. Various bibliometric parameters were summarized, and a comparison between article types was performed. Results: Articles within this study represent principal investigators from 15 countries and were published across 63 journals between 2012 and 2024, with 36.84% of articles originating in the United States. Overall median values were as follows: citation count, 20 (range, 0-2591), number of authors, 9 (range, 2-78), and year of publication, 2020 (range, 2012-2024). Among the top ten most cited articles, BSc articles accounted for all ten reports. Compared to CL and R articles, BSc articles were published in journals with higher impact factors. Conclusion: We establish variability in bibliometric parameters for the most cited publications on H3 G34 DHG. Our findings demonstrate a paucity of high-impact and highly cited CL reports and acknowledge an unmet need to intersect basic mechanism with clinical data to inform novel therapeutic approaches.

Article ; Online: The 2017 AANS Presidential Address. A world of innovation.

Boop, Frederick A

Journal of neurosurgery

Abstract	The 2016 scientific meeting of the American Association of Neurological Surgeons (AANS) focused on the theme "A World of Innovation." In his presidential address, 2016 AANS President Frederick Boop compared the historical development of the specialty of neurological surgery with that of the development of global communications. In the early years, general surgeons training in the United States would spend post-residency time abroad learning from surgical masters in Europe and other places. Since Harvey Cushing's day, neurosurgeons from around the world continue to travel abroad, with many now coming to America for training at centers of excellence. Current clinical practice is defined by multi-national, multi-center clinical trials, and the AANS subsidiary NeuroPoint Alliance has positioned itself to serve as an international center for the oversight of such trials. The Neurosurgery Research & Education Foundation and the Journal of Neurosurgery Publishing Group have made it possible for a neurosurgeon anywhere with Internet access to learn relevant surgical anatomy, learn new neurosurgical procedures, and watch masters in the field perform operations via high-definition surgical videos at no cost via learning platforms such as the Rhoton Collection, the Neurosurgical Atlas, and Neurosurgical Focus video supplements. At the same time, patients are now traveling abroad to seek medical specialty care. Although the globalization of health care poses certain threats, it also presents neurosurgeons with a world of opportunities.

Abstract	Purpose of review: Craniopharyngiomas represent one of the most challenging diseases to treat. Despite their benign histology, and after many decades of surgical experience and technological advancements, there is still no clear consensus regarding the most effective management for this tumor. Due to their location and aggressive local characteristics, purely surgical approaches all too often result in unacceptable morbidity. Recent findings: Partial resection combined with radiation therapy results in similar control rates when compared to aggressive surgery, while also minimalizing the neuro-endocrinological morbidity. In this manuscript, we describe the historical progression of the shifting strategies in the management of pediatric craniopharyngioma. Time has also altered our expectations for outcomes, evolving from purely morbidity and mortality to simple Glasgow Outcomes Scales, now to formal neuro-psychometric and quality of life data.

Abstract	Background and objectives: Competency-based medical education is well established, yet methods to evaluate and document acquisition of surgical skill remain underdeveloped. We describe a novel web-based application for competency-based surgical education at a single neurosurgical department over a 3-year period. Methods: We used a web-based application to track procedural and cognitive skills acquisition for neurosurgical residents. This process included self-assessment, resident peer evaluations, evaluations from supervising attending physicians, and blinded video reviews. Direct observation by faculty and video recordings were used to evaluate surgical skill. Cases were subdivided into component skills, which were evaluated using a 5-point scale. The learning curve for each skill was continuously updated and compared with expectations. Progress was reviewed at a monthly surgical skills conference that involved discussion and analysis of recorded surgical performances. Results: During an escalating 3-year pilot from 2019 to 2022, a total of 1078 cases in 39 categories were accrued by 17 resident physicians with 10 neurosurgical faculty who participated as evaluators. A total of 16 251 skill performances in 110 categories were evaluated. The most evaluated skills were those that were common to several types of procedures, such as positioning, hemostasis, and wound closure. The concordance between attending evaluations and resident self-evaluations was 76%, with residents underestimating their performance in 17% of evaluations and overestimating in 7%. Conclusion: We developed a method for evaluating and tracking surgical resident skill performance with an application that provides timely and actionable feedback. The data collected from this system could allow more accurate assessments of surgical skills and deeper insights into factors influencing surgical skill acquisition.

Abstract	Ependymoma tumors are the third most common pediatric brain tumor. They can be found along the entirety of the neuroaxis, but pediatric ependymomas are most commonly found in the posterior fossa.1 We provide videographic2 description of an anatomic approach to the foramen of Luschka in a pediatric patient through a redo suboccipital craniotomy. In this surgical video, we present a 5-yr-old patient with previously resected ependymoma with recurrence in the foramen of Luschka. The patient underwent microsurgical gross total resection of the ependymoma by using a suboccipital approach. He tolerated the surgery well with an uneventful postoperative course followed by radiation therapy. Regardless of molecular subgroup, numerous studies have shown that near or gross total surgical resection followed by radiation therapy provides the greatest progression-free survival.1,3-6 Ependymomas of the posterior fossa, particularly recurrences or second look resections, can present a challenge to the surgeon because of scarred tissue and precarious location along the brainstem and cranial nerves. Although it has been our institution's observation that these tumors are often debulked, it has been our experience that with an appropriate approach by anatomic dissection, near and gross total resections can be achieved safely and confidently by the surgeon and thus maximize the patient's potential for progression-free survival. The legal guardian of the patient in the presented operative case has given consent for publication of this operative video, and the patient's family provided consent to the procedure.

Abstract	Purpose: Adjuvant radiation therapy (RT) affects survival after surgery for young children (age <3 years) diagnosed with intracranial ependymoma. Conformal photon RT promised to spare normal tissue and was introduced more than 25 years ago to improve outcomes for these vulnerable patients. Long-term results for those first treated with conformal methods provide valuable information and serve as a comparison against newer methods. Methods and materials: Between 1997 and 2018, 101 patients <3.1-years-old were treated with conformal and intensity modulated photon therapy after definitive surgery for intracranial ependymoma. The median age at RT was 2.1 years and the time from diagnosis to the start of RT was 10 weeks. The extent of resection was gross-total in 82%, and 38% underwent more than 1 attempt at resection. The total prescribed dose was 54 to 59.4 Gy at 1.8 Gy per fraction. Results: The 10-year event-free and overall survivals were 58.5% ± 5.0% and 72.6% ± 4.5%, respectively, with a median follow-up of 18.4 years (range, 4.2-23.3 years). Tumor progression occurred in 34 patients with a median time of 1.6 years. Death occurred in 34 patients from ependymoma (n = 24), secondary malignancy (n = 6), necrosis (n = 2), shunt failure (n = 1), and anaphylactic reaction (n = 1). Twenty-three patients developed a secondary tumor including 6 cases of fatal high-grade glioma. Of the surviving cohort and those ≥18 years old, 98% obtained a high school diploma, 64% had a current driver's license, 89% were students or employed full or part time, 32% were living independently, and 70% received higher education or training. Conclusions: Long-term results of children treated using photon conformal RT after surgery demonstrate that adjuvant RT resulted in long-term disease control and functional independence. These results point to the need for new treatment strategies to improve tumor control and provide investigators hope that newer RT methods will further reduce complications.
