Abstract
The surgical treatment of the thalamic lesions is one of the most technically challenging interventions because of their deep-seated location and the proximity of the surrounding vital neurovascular structures: thalamic nuclei, limbic system components, visual and oculomotricity pathways, deep cerebral veins, and posterior cerebral artery branches.1 Traditional microsurgical approaches for these lesions usually require large open craniotomies and further retraction or resection of neural tissue to facilitate better visualization, associating significant postoperative morbidity or even mortality. The recent improvements in high-resolution fiber optics technology have allowed neurosurgeons to expand their surgical armamentarium for tackling these difficult-to-reach lesions. The patient consented to the procedure, and in this surgical video, we try to emphasize the advantages of an endoscopic supracerebellar infratentorial approach over the classic microsurgical approach, along with the keyhole craniotomy and the sitting positioning of the patient. The endoscope provides better visualization-dynamic in-depth view of the anatomic and pathological structures, angled-optics help the surgeon to see "around-the-corner," and the entire procedure is a more comfortable experience for the surgeon and also for the patient, using the minimally invasive techniques. Moreover, we underline the need for a strong collaboration with an experienced endoscopic surgeon (for eg, ear, nose and throat surgeon), as for other endoscopic skull base approaches. The participants and any identifiable individuals consented to publication of his/her image.
