Summary

The cranio-orbital approach offers a safe surgical option for complex anterior circulation aneurysms. This technique provides improved exposure and reduces operative distance without approach-related complications.

Area of Science:

  • Neurosurgery
  • Skull Base Surgery
  • Cerebrovascular Surgery

Background:

  • Complex aneurysms in the anterior circulation present significant surgical challenges.
  • Standard surgical approaches may have limitations in achieving adequate exposure and safe clipping.

Purpose of the Study:

  • To describe the cranio-orbital approach for surgical clipping of complex aneurysms.
  • To prospectively evaluate the complications associated with this surgical approach.

Main Methods:

  • Prospective audit of 25 patients undergoing cranio-orbital approach for aneurysm surgery (1997-2004).
  • Standard pterional approach supplemented with orbital osteotomy.
  • Analysis of aneurysm location and operative outcomes.

Main Results:

  • No approach-related complications were observed in the 25 patients.
  • The cranio-orbital approach was utilized for complex aneurysms, including middle cerebral artery (MCA) and anterior communicating artery (ACOMM) aneurysms.
  • Compared to the standard pterional approach, it reduces operative distance and improves sylvian fissure splitting.

Conclusions:

  • The cranio-orbital craniotomy is a valuable adjunct for surgical treatment of giant or complex aneurysms.
  • It offers advantages such as reduced operative distance and enhanced exposure.
  • This approach provides a wide arc of exposure with multiple working corridors for complex aneurysm clipping.
