A novel scoring system for predisposing factors influencing surgical outcomes: comparing the endoscopic endonasal approach and transorbital approach for trigeminal schwannoma

Key Points

This research aims to develop a scoring system that evaluates factors influencing surgical outcomes for trigeminal schwannoma.
Developed a scoring system based on tumor features and location
Compared two surgical approaches: endoscopic endonasal approach (EEA) and transorbital approach (ETOA)
Analyzed outcomes based on tumor location and carotid artery displacement.
ETOA showed better outcomes for middle cranial fossa (MCF) tumors
EEA is preferred in cases with extracranial tumor involvement.

Abstract

Radiological features, particularly tumor location relative to the OOL and internal carotid artery displacement, significantly influence approach selection and surgical outcomes. The proposed scoring system provides a structured framework for optimizing preoperative decision-making and patient selection. While the ETOA demonstrated superior outcomes for MCF tumors, the EEA remains essential for cases with extracranial involvement.
