| Video Discription | Daniel D. Cavalcanti, MD, PhD,1 and Paulo Niemeyer Filho, MD, PhD2 1Department of Neurosurgery, Barrow Neurological Institute, St. Joseph’s Hospital and Medical Center, Phoenix, Arizona; and 2Department of Neurosurgery, Paulo Niemeyer State Brain Institute, Rio de Janeiro, Rio de Janeiro, Brazil Abstract The pons is the preferred location for cavernous malformations in the brainstem. When these lesions do not surface, it is critical to select the optimal safe entry zone to reduce morbidity.1–3 In this video, we demonstrate in a stepwise manner the medial suboccipital craniotomy and the telovelar approach performed in a lateral decubitus position. They were used to successfully resect a pontine cavernous malformation in a centroposterior location in a 19-year-old patient with diplopia, right-sided numbness, and imbalance. The paramedian supracollicular safe entry zone was used once the lesion did not reach the ependymal surface.2,3 Late magnetic resonance imaging demonstrated total resection and the patient was neurologically intact after 3 months of follow-up. The approach is also demonstrated in a cadaveric dissection to better illustrate all steps. **Intro music: "Daybreak" by Graeme Rosner |
