Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial 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...

Cranial 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,...

Summary
This summary is machine-generated.

Sphenoid wing meningiomas present in different forms and locations, posing surgical challenges. Medial tumors carry higher neurologic risks, while en plaque types are difficult to fully remove due to bone and orbital involvement.

Area of Science:

  • Neurosurgery
  • Oncology
  • Radiology

Background:

  • Sphenoid wing meningiomas are tumors arising from the dura mater.
  • They manifest in globoid or en plaque forms and can be located medially, middle, or laterally along the sphenoid wing.
  • Tumor location and type significantly impact surgical risk and complete resection rates.

Purpose of the Study:

  • To review the clinical presentation of sphenoid wing meningiomas.
  • To discuss the surgical treatment strategies for these tumors.
  • To highlight recent literature findings on surgical outcomes.

Main Methods:

  • Review of clinical presentations based on tumor location (medial, middle, lateral).
  • Analysis of surgical challenges associated with globoid versus en plaque forms.
  • Emphasis on recent literature regarding surgical outcomes and management.

Main Results:

  • Medial sphenoid wing meningiomas present the highest neurologic risk during surgical treatment.
  • Hyperostosing en plaque meningiomas are the most challenging to completely remove due to extensive orbital and bone involvement.
  • Tumor location and subtype dictate the complexity and potential complications of surgical intervention.

Conclusions:

  • Understanding the specific characteristics of sphenoid wing meningiomas is crucial for surgical planning.
  • Tailored surgical approaches are necessary to optimize outcomes and minimize risks.
  • Continued research and literature review are vital for advancing the management of these complex tumors.
