The classification of central nervous system (CNS) tumors has changed greatly. The Central Brain Tumor Registry of the United States (CBTRUS) and other institutions have analyzed the incidence rate and characteristics of primary CNS tumors. However, there are limited studies analyzing the incidence rate and characteristics of CNS tumors in China. To better understand CNS tumors in China, we summarized all primary CNS tumors diagnosed pathologically in a single center from 2003 to 2019. ⋯ Based on this data set, we analyzed various parameters of CNS tumors and found that grade 4 tumors of neuroepithelial tissue were more common in the temporal lobe, which were rarely reported in previous articles.

To compare information online regarding lumbar disc herniation (LDH) on commonly searched websites and compare those findings with the evidence-based recommendations listed in the North American Spine Society (NASS) clinical practice guidelines. ⋯ This study demonstrates that websites regarding LDH contain a mix of information, with only a fraction of recommendations aligning with NASS clinical guidelines. Patients who use these websites are presented with unsubstantiated information, conceivably impacting their understanding, expectations and decision-making in physician offices.

The role of self-citation has not been discussed in the neurosurgery literature, although citations, citation indices, and impact of research may enhance funding opportunities, academic positions, fellowship opportunities, employment, and professional identity development. We sought to assess the magnitude and role of self-citation in academic neurosurgery. ⋯ Academic neurosurgeons must understand the ecosystem around self-citation. In our study, we found overall low levels of self-citations in neurosurgery journals with a few outliers. We have, however, noticed an increasing trend in self-citation rates. Self-citation rates should be considered while evaluating the impact of an author and research productivity. Contrary to popular belief, self-citation is not always unethical and must be understood within its circumstances.

Endoscopic surgery has become the preferred treatment of sellar lesions because of its minimally invasive nature. Visualization is frequently obscured as a result of the frequent contact of the lens with blood and tissue debris. We seek to alleviate these problems and increase the efficiency and safety of neuroendoscopic surgery by introducing a new device (Saraj Endocath) combining the major function of suction with the endoscope. ⋯ The use of the Saraj Endocath can effectively reduce the mean operative time by decreasing the frequency of in-out movement and wiping off the lens of the endoscope. It reduces fatigue, avoids clustering of instruments and hands, and minimizes the dependency on assistants.

Despite growing interest in the endoscopic endonasal approach (EEA) to the medial orbital apex (OA), a comprehensive description of the multilayer topology lying at the intersection of the regional compartments is missing. ⋯ Understanding cranial landmarks and the folds of the layers covering the orbito-cavernous-pterygopalatine interface can facilitate tailoring an EEA to the medial orbital space and avoid unnecessary exposure of sensitive anatomy in the vicinity.
