Summary

The pterional approach offers better surgical outcomes for olfactory meningioma compared to bifrontal craniotomy. This method improves visualization and avoids sacrificing frontal bridging veins, minimizing complications like venous infarction.

Area of Science:

  • Neurosurgery
  • Oncology

Background:

  • Olfactory groove meningiomas require surgical removal.
  • Traditional bifrontal craniotomy limits visualization of the posterior tumor pole.
  • Bifrontal craniotomy can lead to complications from sacrificing frontal bridging veins.

Purpose of the Study:

  • To evaluate the efficacy of the pterional approach for olfactory meningioma.
  • To compare the pterional approach with bifrontal craniotomy.
  • To assess the impact on surgical damage and complications.

Main Methods:

  • Retrospective analysis of 20 patients with olfactory meningioma.
  • Surgical intervention using the pterional approach since 1975.

Main Results:

Related Experiment Videos

  • The pterional approach yielded good results in 90% of cases.
  • This approach provides better visualization of the tumor.
  • It avoids the planned sacrifice of venous vessels, reducing risks.

    • Conclusions:

    • The pterional approach is a advantageous alternative to bifrontal craniotomy for olfactory meningioma.
    • It minimizes surgical damage and associated complications.
    • Improved visualization aids in effective tumor removal.
