Abstract

Insights

Sphenoid wing meningioma en plaque surgery using the transcranio-orbital approach effectively treated proptosis and visual deficits. Complete bone removal is crucial for preventing recurrence and achieving good outcomes.

Area of Science:

  • Neurosurgery
  • Ophthalmology
  • Oncology

Background:

  • Sphenoid wing meningioma en plaque is a distinct intracranial meningioma subtype characterized by extensive hyperostosis and orbital invasion.
  • This condition presents with symptoms like proptosis and visual acuity deficits.

Purpose of the Study:

  • To summarize surgical experiences with the transcranio-orbital approach for sphenoid wing meningioma en plaque.
  • To evaluate the efficacy and safety of this surgical technique.

Main Methods:

  • Retrospective study of 37 patients treated between 1998 and 2009.
  • Utilized a fronto-temporal approach with orbital decompression.
  • Assessed tumor resection extent, clinical outcomes, and complications.

Main Results:

  • All patients experienced improvement in proptosis; 69% showed improved visual acuity.
  • Simpson grade II resection achieved in 9 patients, grade III in 22, and grade IV in 6.
  • Tumor recurrence occurred in 7 patients, necessitating further surgery in 5.

Conclusions:

  • Sphenoid wing meningiomas, often meningothelial, require complete hyperostosis removal to prevent recurrence.
  • Extensive tumor resection and orbital apex decompression yield satisfactory cosmetic and functional results.
  • Multidisciplinary collaboration between neurosurgeons and ophthalmologists is vital.

Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

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

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...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
