Area of Science:

  • Neurosurgery
  • Ophthalmology
  • Oncology

Background:

  • Cavernous sinus meningiomas significantly impact patients through cranial nerve deficits.
  • Radiosurgery has shifted management, but mass effect symptoms persist.
  • A combined approach of surgical decompression and radiation therapy is employed.

Purpose of the Study:

  • To evaluate the efficacy of endoscopic endonasal decompression (EED) for symptomatic cavernous sinus meningiomas.
  • To assess the functional outcomes of EED on cranial nerve deficits.
  • To determine the safety and complication rates of EED in this patient cohort.

Main Methods:

  • Retrospective review of 17 patients undergoing EED for cavernous sinus meningiomas (2010-2016).
  • Comparison of pre-operative and 1- and 6-month post-operative neuro-ophthalmological examinations.
  • Analysis of hospital stay, complications, and radiological/clinical follow-up.

Main Results:

  • Significant improvement in cranial nerve deficits, with 62.5% normalization of CNII deficits at 6 months.
  • Of patients with cavernous sinus cranial nerve deficits, 33.33% normalized and 58.3% partially improved at 6 months.
  • No intraoperative complications were reported, indicating a safe procedure.

Conclusions:

  • Endoscopic endonasal decompression is a valuable technique for acute/subacute cranial nerve deficits in cavernous sinus meningiomas.
  • This conservative surgical approach demonstrates good functional outcomes with low morbidity and complication rates.
  • EED does not replace the need for subsequent radiosurgery or radiation therapy for tumor growth control.
