Background And Objectives: Given the complex anatomy of the operative region and individual surgeon preferences, some techniques for soft tissue dissection before pterional craniotomy have gained more popularity than others. This prospective study used subjective and objective measurements to compare the functional, radiological, and aesthetic outcomes of 3 such dissection techniques.
Methods: This multicenter prospective cohort study included all patients who underwent elective pterional craniotomy between 2018 and 2020 at 3 centers in Riyadh, Saudi Arabia.
Background: Delirium in critically ill patients is independently associated with poor clinical outcomes. There is a scarcity of published data on the prevalence of delirium among critically ill patients in Saudi Arabia. Therefore, we sought to determine, in a multicenter fashion, the prevalence of delirium in critically ill patients in Saudi Arabia and explore associated risk factors.

The purpose of this study is to examine the relation between the maximum diameter of the MSWM medial to the anterior clinoidal line (AC line) and surgical outcome. This is a retrospective cohort study investigating all surgically resected MSWM cases at our institution over 10 years.

- A newly observed phenomenon called the oculoglossal phenomenon involves the involuntary movement of the tongue to the same side as voluntary eye movements, offering insights into brainstem function.
- In an observational study conducted with 60 participants, 83.3% displayed this reflex when instructed to move their eyes and tongue simultaneously.
- The proposed anatomical pathway for this phenomenon begins in the frontal cortex and involves several brainstem structures, suggesting it may be a valuable addition to neurological evaluations if further validated.
Background: Internal carotid artery (ICA) injuries are a major complication of endoscopic endonasal approaches (EEAs), which can be difficult to manage. Adding to the management difficulty is the lack of literature describing the surgical anatomical classification of these types of injuries. This article proposing a novel classification of ICA injuries during EEAs.

- The study conducts a bibliometric analysis of the top 100 most-cited articles on cerebral vasospasm, aiming to understand their scientific impact and relevance in the field.
- The analysis reveals that these articles have a total of 20,972 citations, with clinical studies being the most common, especially from the years 1998 to 2005.
- The findings highlight key trends in publication, with most articles from the United States and the University of Alberta being the leading research institution, ultimately helping clinicians enhance their understanding and practice related to cerebral vasospasm.
Introduction: Intracranial meningiomas account for 30% of all primary intracranial tumors. Surgical resection remains the mainstay of the treatment for meningiomas. The magnetic resonance of intracranial meningiomas has been largely discussed in many reports of the radiological and neurosurgical literature.

The aim of this study is to determine the correlation between the aneurysm size, location, and multiplicity, and their effect on aneurysmal rupture.
Materials And Methods: Eighty one patients with diagnosis of intracranial aneurysms were managed at our center from January 2008 through July 2011.
Introduction: Intracranial cystic meningiomas are rare and preoperative diagnosis is difficult. The present study was performed to assess the clinical and radiological outcome of intracranial cystic meningiomas.
Methods: We performed a retrospective analysis of 13 patients (mean age: 49.
Objective: To evaluate potential risk factors that can predict the development of hydrocephalus (HCP) in adult patients with intraventricular hemorrhage (IVH).
Methods: Retrospective analysis of all adult patients presented to King Fahad Medical City between 2004 and 2011 with intraventricular hemorrhage to evaluate different variables and their association with HCP.
Results: A total of 31 patients were included in the study, 14 patients (45.
Objective: To determine the prevalence of symptoms and risk of obstructive sleep apnea (OSA) among patients with ruptured cerebral aneurysms.
Methods: In this case-control study, a validated Arabic version of the Berlin Questionnaire (BQ) was administered to patients admitted to King Fahd Medical City, Riyadh, Saudi Arabia with cerebral aneurysms between January 2006 and July 2011 (n=53). The same questionnaire was administered to a control group comprised of patients attending primary health care clinics who were matched for age, body mass index (BMI), and gender (n=212).
This report describes a rare case of ventrally exophytic pontine glioma describing operative and neuroanesthesia management. The combination of intraoperative neuromonitoring was used. It constituted: Brain stem evoked responses/potentials, Motor EP: recording from cranial nerve supplied muscle, and Sensory EP: Medial/tibial.
