Suboccipital retrosigmoid approach for resection of cerebellopontine angle tumor
video

This is a demonstration of the retrosigmoid approach for microsurgical resection of a cerebellopontine angle tumor. Th patient presented with gait disturbance and normal hearing. A suboccipital craniotomy was used for access to the cerebellopontine angle. Using microsurgical technique, the tumor was dissected away from the glossopharyngeal nerve. Pathological analysis confirmed that the tumor was a schwannoma of the glossopharyngeal nerve. DOI# http://dx.doi.org/10.17797//r3wbfb5hkv

Endoscopic endonasal approach for odontoidectomy
video

Contributors: M. Nathan Nair and Timothy Deklotz For patients with basilar invagination, an odontoidectomy may be necessary to decompress the brainstem, before further correction and stabilization of the craniocervical junction can be achieved. The open-mouth odontoidectomy procedure is associated with significant moribdity, and the endoscopic endonasal approach may be a better option. In this video, we provide a step-by-step demonstration of the endoscpic endonasal approach for odontoidectomy. DOI:http://dx.doi.org/10.17797/6mx9qe789f

Anterior Petrosectomy and Resection of a Meckel's Cave Schwannoma
video

Contributors: Daniel Felbaum and H. Jeff Kim The video demonstrates the resection of a trigeminal schwannoma via a middle fossa craniiotomy and anterior petrosectomy. A large dumbbell-shaped tumor was essentially two tumors in one. The anterior petrosectomy provided access mainly to the posterior component of the tumor, which was compressing the pons, and obscured by the tentorium and petrous ridge. Mobilization of the lateral wall of the cavernous sinus freed the anterior component and thus allowed the removal of the rest of the schwannoma. DOI# http://dx.doi.org/10.17797/8hbvtjdj0l
