Implication

Cadaveric study demonstrates an effective surgical corridor for accessing critical brain regions.

Key Points

The study aims to evaluate the feasibility of an extradural endoscopic orbitozygomatic approach for accessing the orbit, cavernous sinus, and infratemporal fossa.
Dissection of five formalin-fixed cadaveric heads (10 sides) using an extradural orbitozygomatic approach.
Supplementary use of 0° and 30° rigid endoscopes for enhanced visualization.
Assessment of anatomic exposure and corridor continuity qualitatively.
Established a continuous corridor from the orbit to the infratemporal fossa and petroclival region.
Improved visualization of key structures including the cavernous sinus wall and trigeminal divisions.
Anterior petrosectomy extended exposure towards the upper clivus and ventrolateral brainstem.
