Background: The blood supply to the skull base is important to surgeons and those performing interventional and diagnostic procedures in this region. However, 1 vessel with a vast distribution in this area, the dorsal meningeal artery (DMA), has had few anatomic studies performed to investigate not only its normal anatomy but also its variations. Therefore the current study aimed to analyze the DMA via cadaveric dissection.
Methods: In 10 adults, latex-injected, cadaveric heads (20 sides), the DMA was dissected using a surgical microscope. This artery and its branches were documented and measured.
Results: A DMA was identified on all sides. In the majority (85%), it was a branch of the meningohypophysial trunk or common stem with either the inferior hypophysial or tentorial arteries and always had branches that traversed the basilar venous plexus. Multiple branches of the DMA were identified and categorized as bony, dural, neural, and vascular.
Conclusions: Surgeons operating at the skull base or clinicians interpreting imaging of this area should have a good working knowledge of the DMA and its typical and variant anatomy.

The study examines the morphometric development of the anterior cranial fossa in human fetuses and its clinical implications. The anterior cranial fossa, crucial for protecting the frontal lobes, was analyzed during prenatal development using innovative computer image processing techniques. We hypothesized that the growth of the anterior cranial fossa is not uniform throughout fetal development and that changing geometric relationships are important for possible therapeutic interventions in cases of congenital defects.

Unlabelled: Intracranial complications in inflammatory diseases of the ear and nose are currently not frequent, but their lethality remains high. The choice of optimal, safe and effective access in surgical treatment of purulent-inflammatory intracranial complications remains a subject of discussions and is based on an individual approach, depends on the volume, localization and clinical condition of the patient.
Objective: To demonstrate a clinical case of successful drainage of the brain frontal lobe abscess using endoscopic transnasal access under the control of the navigation system.
Post-Operative Outcome Predictions in Vestibular Schwannoma Using Machine Learning Algorithms.

Division of Neurotology and Skull Base Surgery, Department of Otolaryngology-Head and Neck Surgery, University of California, Irvine, CA 92697, USA.
This study aimed to develop a machine learning (ML) algorithm that can predict unplanned reoperations and surgical/medical complications after vestibular schwannoma (VS) surgery. All pre- and peri-operative variables available in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (n = 110), except those directly related to our outcome variables, were used as input variables. A deep neural network model consisting of seven layers was developed using the Keras open-source library, with a 70:30 breakdown for training and testing.
