Endoscopic Endonasal Accessibility And Maneuverability Around The Internal Carotid Artery From Distal Dural Ring To Foramen Lacerum: Cadaveric Study, Alhusain Nagm
Al-Azhar International Medical Journal
Background: Expanded-endoscopic endonasal approaches (eEEA) to surgical targets around the internal carotid artery (ICA) remain inspiring and necessitate a special learning curve. Methods: Six formalin-fixed heads were dissected to study the 360° accessibility and manoeuvrability around ICAs from the distal dural ring (DDR) to the foramen lacerum (FL) on each side (n=12) via eEEA. The ICA course was divided into three segments: ICA in cavernous sinus (CS-ICA), paraclival-ICA and lacerum-ICA. Following total exposure of each ICA, the three-dimensional (3D= medial/lateral, superficial/deep and above/below) anatomical targets (n= 35) around each ICA were evaluated. The data were collected and analyzed. Results: Distinctively, …
