Glioblastoma is the most aggressive primary brain tumor and the outlook for patients is usually pessimistic. Numerous ongoing studies have focused on enhancing the survival rate of glioblastoma patients. This study aims to analyze the research trends surrounding glioblastoma survival and facilitate studying recent topics to provide insight into the perspective, research fields, and international collaborations. ⋯ Considering the significance of monitoring the studies in glioblastoma patients, the current research has shown promising results in stratifying patient survival as a valuable tool for prognosis and prediction and eventually guiding treatment decisions. Using the results of this study, glioblastoma researchers can identify their potential colleagues and research gaps in this field.

Trigeminal neuralgia (TN) has been described as one of the worst pains known to humankind. However, pain severity in TN has been measured using several different scales, resulting in difficulty comparing illness burden and response to TN surgery across studies. We examined the degree of concordance between standardized scales evaluating pain severity in a cohort of patients undergoing surgery for TN. ⋯ TN patients with residual mild-moderate pain after surgery are often discordantly classified by different pain measurement scales. These findings argue for a more standardized method of reporting postoperative pain outcomes in the TN literature.

Chiasmatic cavernous hemangioma (CCH) is a rare disease. Most cases are treated with surgical resection through approaches such as pterional and orbitozygomatic craniotomy. However, with advancements in surgical technique and heightened patient demand for improved postoperative quality of life, there have been reports in recent years exploring more minimally invasive surgical approaches, such as the subfrontal trans-eyebrow keyhole and endoscopic endonasal transsphenoidal approach. In this article, the cases of CCH in the reported literature are reviewed, the indications and techniques of minimally invasive surgery for the removal of CCH through the subfrontal trans-eyebrow keyhole approach are discussed, and the effects of different surgical approaches are analyzed. ⋯ According to our results, the subfrontal trans-eyebrow keyhole approach for the resection of CCH is mainly suitable for cases in which the lesions are located above and anterior to the optic chiasm, the medial or superior aspect of the intracranial segment of the optic nerve is involved, and there is no invasion into the optic nerve canal. Compared with the traditional surgical approach, the minimally invasive subfrontal trans-eyebrow keyhole approach has demonstrated better clinical outcomes in the resection of CCH. However, according to the specific conditions of different patients, it is still necessary to comprehensively consider the choice of surgical approach. This study provides a valuable reference for further exploration of the treatment of CCH.

N-butyl cyanoacrylate (n-BCA) is often used for preoperative transarterial embolization (TAE) of meningiomas. However, factors affecting the embolization effect with n-BCA remain unclear. This study aimed to clarify the factors associated with the embolization rate after TAE using n-BCA in meningioma, from the aspect of feeder architecture. ⋯ The OphA feeder group was associated with a lower embolization rate. Our study suggested that the vascular architecture in meningioma affected the efficacy of TAE with n-BCA.

Subdural drains are used to reduce recurrence after surgical evacuation of chronic subdural hematoma. There is a small risk of parenchymal injury. We hypothesize that using subgaleal drains with low active suction (-50 mm Hg to -100 mm Hg) may be a safer alternative and still maintain efficacy in preventing recurrence. ⋯ The use of subgaleal drains with low active suction led to significantly lower complication rates compared with the use of subdural drains and maintained its efficacy in preventing recurrence.
