Subfrontal trans-lamina terminalis approach to a third ventricular craniopharyngioma. Neurosurgical focus Choudhri, O., Chang, S. D. 2016; 40 Video Suppl 1: 2016.1.FocusVid.15416


Craniopharyngiomas are benign, partly cystic epithelial tumors that can rarely occur in a retrochiasmatic location with involvement of the third ventricle. The lamina terminalis is an important neurosurgical corridor to these craniopharyngiomas in the anterior portion of the third ventricle. We present a video case of a large midline suprasellar and third ventricular craniopharyngioma in a 32-year-old male with visual disturbances. The tumor was approached with a subfrontal translamina terminalis exposure, and a gross-total resection of the tumor was achieved. This surgery involved working through a lamina terminalis fenestration around the optic nerve, optic chiasm, optic tracts, and the anterior communicating artery complex. This video illustrates the techniques employed in performing a transbasal anterior skull base approach to the third ventricle and demonstrates vivid surgical anatomy of neurovascular structures around the lamina terminalis.
