Skull base approaches enhance surgical treatment for cerebral aneurysms by improving access and visualization. This study found these methods safe and effective for complex cases, with no mortality.

Area of Science:

  • Neurosurgery
  • Vascular Surgery

Background:

  • Cerebral aneurysms, particularly giant or complex ones, pose significant surgical challenges.
  • Traditional surgical approaches may involve extensive brain retraction and limited operative fields.

Observation:

  • Skull base approaches were utilized in 22 patients with ruptured giant or complex aneurysms.
  • Specific approaches included orbitocranial, orbitozygomatic, petrosal, and far lateral-transcondylar, tailored to aneurysm location.
  • These techniques facilitated early vascular control, widened the operative field, and minimized brain retraction.

Findings:

  • Skull base approaches improved the ease of clipping and dissection for cerebral aneurysms.
  • No surgical mortality was observed in the patient cohort.
  • Transient cranial nerve paresis was the primary morbidity associated with the approaches.

Implications:

  • Skull base surgery offers a safe and effective alternative for managing complex cerebral aneurysms.
  • These approaches provide superior spatial geometry and access compared to conventional methods.
  • Further investigation into the nuances of skull base approaches can refine surgical outcomes.
