Anatomical insights into the peri-trigeminal zone via transorbital, transclival, and retrosigmoid routes: a comparative cadaveric study with surgical implications

Key Points

• This study aims to evaluate anatomical and technical aspects of three surgical approaches to the peri-trigeminal zone (PTZ).
• Conducted a comparative cadaveric study of three surgical routes: transorbital, transclival, and retrosigmoid.
• Examined the orientation of lesions within the pons as a key factor for surgical approach selection.
• Documented anatomical nuances associated with each surgical route.
• Identified that lesion orientation significantly influences the choice of surgical approach.
• Provided detailed anatomical insights that can enhance surgical decision-making for pontine lesions.
