A BSTRACT The adoption of keyhole approaches for intracranial aneurysm clipping has increased in neurosurgery. Select anterior-circulation aneurysms are amenable to minimally invasive exposure via the supraorbital keyhole, lateral supraorbital and mini-pterional approaches. Choice of approach depends on aneurysm location and angioarchitecture. Although these cosmetically favourable techniques appeal to both patients and surgeons, many neurosurgeons remain apprehensive about managing intraoperative events through smaller corridors. This narrative review summarises the available literature on benefits and limitations of keyhole clipping for anterior circulation aneurysms, highlights technical pearls, and addresses the common concerns of young neurosurgeons to help guide safe adoption.
