Supracerebellar transtentorial removal of a large tentorial tumor
Large tumors located on the upper surface of the tentorium, extending to the posterior edge of the tentorial incisura and affecting the posterior temporo-mesial region, are challenging to reach without damaging the surrounding brain. Typically, these lesions are approached through a subtemporal or a transcortical transtemporal corridor. To avoid temporal lobe transgression or retraction, and venous drainage compromise, we use a supracerebellar transtentorial (SCTT) approach which gives a direct exposure to the posterior temporo-medial region and the posterior incisural space. In this video, we demonstrate the surgical technique of the SCTT approach. 1Division of Neurosurgery, Department of Surgery, Notre Dame Hospital, Montreal, QC, Canada; 2Division of Pediatric Neurosurgery, Department of Surgery, Sainte-Justine Hospital, Montreal, QC, Canada; and 3Department of Neurosurgery, King Fahad University Hospital, Dammam University, Saudi Arabia
