    Olfactory loss has increased post-COVID-19, impacting quality of life and leading to higher depression rates.

  • 2

    Olfactory implants are being developed to stimulate the olfactory system and improve olfactory function.

  • 3

    The olfactory bulb (OB) is a promising target for neurostimulation due to its organized structure and easier surgical access.

  • 4

    This study compared electrode placements on the dorsal OB and ventral olfactory tract (OT) using a supraorbital keyhole approach.

  • 5

    Implantation on the OT was more stable and required less invasive techniques compared to the OB, reducing operative time.
