Neurosurgical training and practice rely heavily on research, which is a pivotal marker of academic productivity. This study investigates the current landscape of neurosurgery publications originating from Pakistan, encompassing overall research output, prevalent topics, and disparities across institutions and regions. Electronic databases, including PubMed, Scopus, Web of Science, and ScienceDirect, were systematically searched up to November 1, 2023, using specified keywords.

In general, these tumors are benign paragangliomas with the definitive treatment consisting of radiosurgery or surgery. Endovascular embolization can be added as a critical adjunctive therapy to reduce the tumor vascularity before surgical resection.

- The study explores the infratentorial presigmoid retrolabyrinthine suprameatal approach (PRSA) for surgically treating aneurysms in the proximal third of the anterior inferior cerebellar artery (AICA), which traditionally requires complex techniques.
- Researchers conducted dissections and analyzed morphometric parameters in cadaveric heads to assess the approach's feasibility and anatomical variations.
- Findings suggest that the PRSA corridor allows for effective access to AICA aneurysms without risking hearing or balance, emphasizing the importance of individualized preoperative assessments to identify suitable patients.
Article Synopsis
- The ambient cistern (AC) and the ambient wing cistern (AWC) are complex anatomical structures in the brain, first defined by Dr. Bengt Liliequist in the 20th century, but have caused confusion in neuroanatomy over the years due to their intricate three-dimensional anatomy.
- A thorough literature review identified 60 relevant research articles after filtering out unrelated studies, revealing that while multiple related cisterns are described, they are often not presented as singular entities in medical literature.
- The study concludes that the AC and AWC are anatomically distinct yet interconnected structures, significant for diagnostic and surgical considerations related to brain masses near the tentorial hiatus, and can be approached via specific surgical methods.
Background: Middle meningeal artery embolization (MMAE) has revolutionized the armamentarium for chronic subdural hematoma (CSDH) treatment. Technical and angiographic benchmarks to guide procedural and clinical success are less well established.
Methods: A single-center database was reviewed to compare outcomes after standalone MMAE with and without resultant residual angiographic opacification of frontal and parietal (F/P) branches.
