Supraorbital keyhole approach for suprasellar arachnoid cyst: how I do it

Background Keyhole approaches have lately sparked strong interest because these approaches address skull base pathologies as reported by Eroglu et al. (World Neurosurg, 2019); Hickmann, Gaida, and Reisch (Acta Neurochir (Wien) 159:881–887, 2017); Jallo and Bognar (Neurosurgery, 2006); and Poblete et al. (J Neurosurg 122:1274–1282, 2015), minimizing brain retraction and improving cosmetic results. We describe the step-by-step surgical technique to drain a suprasellar arachnoid cyst by a supraorbital approach.
