AbstractThe temporomesial region is a frequent site of neurosurgical lesions such as tumors, cavernomas, or arteriovenous malformations. This region has been divided into 3 regions: anterior, middle, and posterior.1-4 The objective of Video 1 is to present the case of a posterior temporomesial cavernoma resection through a supracerebellar transtentorial approach, highlighting the surgical technique. The case is a 50-year-old female with history of temporomesial bleeding, headaches, and seizures refractory to medical treatment. In the neuroimaging studies a posterior temporomesial image was diagnosed. We selected a paramedian supracerebellar transtentorial approach in semisitting position for the surgery. With the use of neuronavigation guidance, the cavernoma was located and removed in 1 piece. The patient evolved favorably, without neurologic deficit, improving the symptoms after surgery. The approach is an excellent alternative for exposing the temporomesial region, and the semisitting position facilitates the retraction by gravity of the cerebellum, maintaining a clean surgical field during the microsurgical procedure.3-5.Copyright © 2021 Elsevier Inc.
