We describe the concept and technique of the supraorbital keyhole approach. Methods: The supraorbital keyhole approach is performed through an eyebrow skin incision. Image guidance may be used to define the optimal surgical trajectory. A limited supraorbital craniotomy is fashioned. The frontal lobe is mobilized and the central skull base approached, without the need for brain retractors. Endoscopy is used to enhance visualization, and tube-shaft instruments to improve manipulation through the narrow surgical corridor. Conclusions: The supraorbital keyhole approach provides a safe method to access selected skull base lesions.
