    Endoscopic transorbital approach (ETOA) is increasingly used for accessing the ventral skull base.

  • 2

    Intraocular pressure (IOP) can dangerously increase due to orbital retraction during ETOA, especially beyond 1.5 cm.

  • 3

    Removal of the lateral orbital rim (LOR) may enhance the working space during ETOA, but its impact on intraorbital pressure is unclear.

  • 4

    A solid-state strain-gauge microtransducer was utilized to monitor intraorbital pressure in cadaveric specimens during ETOA.

  • 5

    The study aimed to evaluate the effects of LOR removal on intraorbital pressure and quantify bone removal during ETOA.
