Overview

Prospective observational study demonstrates favorable surgical efficacy and low morbidity in patients undergoing exoscopic supraorbital keyhole surgery, highlighting its ergonomic utility.

Key Points

To evaluate the feasibility, ergonomic utility, and safety of an exoscope-assisted supraorbital keyhole approach for resecting anterior skull base lesions.
Prospective observational study conducted over 7 years in a single neurosurgery department with a sample size of N=50 patients harboring anterior skull base lesions.
Surgeries utilized an exoscope setup featuring a 2D VITOM rigid-lens telescope (10-mm diameter, 14-cm shaft), xenon light source, pneumatic holding arm, and video display monitor via an eyebrow keyhole incision.
Pathology comprised meningiomas (38%), pituitary adenomas (30%), aneurysms (6%), and other lesions; complete tumor resection or aneurysm clipping occurred in 84% (42/50) of cases, with near-total resection in 16% (8/50).
Complications were limited to inadvertent frontal sinus violation in 8% (4/50) and postoperative cerebrospinal fluid leaks in 4% (2/50), with no cosmetic deformities observed.
Operative duration ranged from 2 to 4 hours, exoscope repositioning was limited to at most nine adjustments per case, and all 50 patients achieved favorable Glasgow Outcome Scale scores (4/5 or 5/5).
