Neurosurgery·2001

Area of Science:

  • Neurosurgery
  • Ophthalmology
  • Endoscopic Surgery

Background:

  • Meningiomas can compress critical neural structures like the optic nerve, leading to visual impairment.
  • Traditional surgical approaches for intracranial tumors may involve significant morbidity.

Observation:

  • A 58-year-old woman presented with progressive left-eye visual loss due to a 10x15 mm mass compressing the optic nerve.
  • Magnetic resonance imaging confirmed a contrast-enhancing tumor, and visual field testing revealed significant defects.

Findings:

  • The tumor was completely excised using an endoscopic endonasal technique through the right nostril.
  • Histological examination identified the tumor as a meningothelial meningioma.
  • The patient experienced improved vision post-surgery with a residual temporal-field defect.

Implications:

  • Endoscopic endonasal surgery is a viable and effective minimally invasive option for optic nerve meningiomas.
  • This technique potentially reduces surgical risks and recovery time compared to open procedures.
  • Further research can explore the long-term outcomes and applicability of this approach for other intracranial tumors.
