Endoscope-Assisted Middle Fossa Approach: Optimizing the Surgical Corridor for the Resection of Multicompartmental...

Area of Science:

• Neurosurgery
• Oncology

Background:

• Skull base chordomas present significant surgical challenges.
• Optimal surgical management requires balancing maximal tumor removal with patient safety.
• Choosing the right surgical approach is critical for successful outcomes.

Purpose of the Study:

• To evaluate the efficacy of an endoscope-assisted middle fossa approach for skull base chordomas.
• To demonstrate the benefits of endoscopic assistance in improving surgical corridor access and tumor resection.

Main Methods:

• Retrospective review of medical records and imaging for two patients with skull base chordomas.
• Surgical treatment utilizing an endoscope-assisted middle fossa approach.

Main Results:

• Endoscopic assistance facilitated superior identification of anatomical landmarks compared to microscopic techniques.
• Improved tumor resection was achieved with the endoscope-assisted approach.
• The study discusses approach selection, landmark identification, and technical aspects of the endoscopic procedure.

Conclusions:

• Endoscopic assistance is a safe and effective adjunct for the middle fossa approach in treating skull base chordomas.
• This technique maximizes surgical corridor reach, potentially leading to more complete tumor removal.
• The findings support the integration of endoscopic tools in managing these challenging tumors.
