Free-hand Frameless Pinless Electromagnetic-Navigation (AXIEM™)-Guided Brain Lesion Biopsies: An Institution Based Experience from a Low-Middle-Income Country.

Objectives: To evaluate the precision and safety of a novel technique of free-hand frameless pinless AXIEM™-based navigation guided biopsy of deep-seated brain lesions in a low-middle income country.

Methods: This retrospective study included 45 patients who underwent free-hand frameless pinless AXIEM™-based navigation guided biopsy of deep-seated brain lesions using the Medtronic-Stealth S7 system over a 5-year period (January 2019 to December 2023) at the Department of Neurosurgery, Punjab Institute of Neurosciences, Lahore, Pakistan.

Results: A total of 45 patients were included in this study.
