What’s inside
5 sections · 34 slides
Overview
- First, where are we operating?
- The big idea of the eyebrow orbitotomy
- Why surgeons reach for this approach
Background and rationale
How the keyhole idea grew out of the standard subfrontal craniotomy
- From big openings to keyholes
- What the anatomy studies tell us
Indications
Which tumors and problems this route is chosen for
- The classic targets: anterior skull-base meningiomas
- Beyond meningiomas
- The main limitation to respect
- Matching the tumor to the approach
Operative technique
Step by step, from positioning to opening the dura
- Positioning and preparation
- The incision and soft tissue
- Freeing the bone and lifting the flap
- Managing the frontal sinus and opening the dura
- The key trick: let the fluid do the retracting
- CSF drainage opens the keyhole view
- Aiming the microscope before you retract
- Anticipatory microscope positioning
- Reaching deeper with the endoscope
- Through the opticocarotid triangle
Closure, outcomes, and cautions
Finishing the operation and what patients can expect
- Closing up
- Planum sphenoidale meningioma, before and after
- What the approach achieves
- Honest cautions to share with patients
- Why does draining CSF from the basal cisterns make the eyebrow orbitotomy possible?
