Resection of a Retrochiasmatic Craniopharyngioma by Combined Modified Orbital Craniotomy and Transnasal Endoscopic Techniques.

A 20-year-old patient presented with hydrocephalus but intact vision and hormone function. The MRI showed a large seller, suprasellar and third ventricular mass. We chose a combined approach utilizing the translyvian, lamina terminals route, with a possible interhemispheric approach. But, we also utilized a transnasal endoscopic approach for the tumor that remained below the diaphragma sellae. The patient did well, with complete tumor resection via a staged approach, but did require hormone replacement. The link to the video can be found at: https://youtu.be/yzpfOxzI4cQ .
