The Supraorbital Keyhole Craniotomy through an Eyebrow Incision: Its Origins and Evolution
Figure 3
(a) Preoperative and (b) postoperative MR images of a heterogeneously enhancing cystic mass involving the sella and suprasellar region. Pathology was consistent with craniopharyngioma. Near-total resection was achieved. (c) Microscopic images from surgery demonstrate optic nerve (ON) and its relationship to tumor (T). (d) Comparison image from endoscopic view in the same patient now demonstrating both optic nerves (ON) and infundibulum (I) following tumor resection. Note the wider field of view, greater visibility, and contrast at depth. There is also significantly less blur from anatomy obscuring view superficial to focal point as clearly noted in microscopic image (c).
