Summary
Foramen magnum meningiomas (FMMs) present unique challenges due to their location. This review emphasizes surgical approaches for these complex tumors, highlighting techniques for various tumor locations.
Area of Science:
- Neurosurgery
- Oncology
Background:
- Foramen magnum meningiomas (FMMs) are challenging tumors due to their location and potential for significant neurological compromise.
- Symptoms vary widely based on involvement of critical structures like the spinal cord, lower cranial nerves, and brainstem.
Purpose of the Study:
- To review foramen magnum meningiomas (FMMs).
- To emphasize and compare surgical approaches for FMM resection.
Main Methods:
- Review of literature focusing on surgical techniques for foramen magnum meningiomas.
- Discussion of anatomical considerations and surgical corridor modifications.
Main Results:
- Posterior and posterolateral FMMs are accessible via midline suboccipital approach.
- Anterior and anterolateral FMMs often require modifications of the far lateral approach, potentially involving condylar drilling or resection.
Conclusions:
- Surgical approach selection for FMMs depends on tumor location and extension.
- Careful surgical planning is crucial for successful resection and minimizing neurological deficits.

01:19Cranial and Spinal Meninges
3.2K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:18Anatomy of the Brain: Ventricles
7.2K
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.

01:54The Spinal Cord
31.1K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

01:26Bone Markings
7.7K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:15Spinal Cord: Gross Anatomy
5.0K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

01:14Cranial Bones: Superior and Posterior View
4.6K
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,...
