Summary
This review details skull base triangles, crucial geometric landmarks for safe surgical approaches. Understanding these anatomical regions aids in navigating complex skull base lesions.
Area of Science:
- Anatomy
- Neurosurgery
- Skull Base Surgery
Background:
- Multiple anatomical triangles exist within the skull base.
- A comprehensive review of these geometric landmarks is currently lacking.
- Safe and consistent surgical approaches to skull base lesions require detailed anatomical knowledge.
Purpose of the Study:
- To provide a comprehensive review of the major skull base triangles.
- To illustrate the anatomical borders, dimensions, and variations of these triangles.
- To highlight the surgical implications of understanding these landmarks for lesion management.
Main Methods:
- Literature review of anatomical variations and surgical approaches related to skull base triangles.
- Compilation of illustrations depicting major skull base triangles.
- Analysis of anatomical borders, dimensions, and surgical relevance.
Main Results:
- Detailed overview of major skull base triangles.
- Illustrations of anatomical landmarks and their variations.
- Discussion of surgical implications for approaching lesions near critical structures like the internal carotid artery, internal acoustic meatus, and cavernous sinus.
Conclusions:
- A comprehensive understanding of skull base triangles is essential for safe and effective surgical interventions.
- This review provides a valuable resource for surgeons operating in the complex skull base region.
- Accurate anatomical knowledge of these triangles facilitates precise navigation and management of skull base pathologies.

01:18Anatomy of the Brain: Ventricles
9.4K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

01:14Cranial Bones: Superior and Posterior View
8.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:26Cerebrum: Anatomical Overview I
5.6K
The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...

01:08Overview of the Skull
8.1K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...
