چکیده
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 study 360° accessibility manoeuvrability ICAs from distal dural ring (DDR) foramen lacerum (FL) on each side (n=12) via eEEA. The ICA course was divided into three segments: in cavernous sinus (CS-ICA), paraclival-ICA lacerum-ICA. Following total exposure of ICA, three-dimensional (3D= medial/lateral, superficial/deep above/below) anatomical (n= 35) evaluated. data collected analyzed. Results: Distinctively, we included 35 (pertinent CS-ICA, lacerum-ICA 16, 10, 9, respectively) every DDR FL. Although reasonable visual validation possible for all targets, micro-dissections safely achievable 19 (54.3%) through full or limited freedom 73.7% 26.3%, respectively. In remaining 45.7%, abandoned due hazardous manipulation. most unreachable (55.6%) with extremely restricted maneuverability (75%). Though, favorable (60%) (100%) paraclival-ICA. Conclusion: This delivers distinctive view appreciate degree complexity invasiveness relation Illustrating these details skull base surgeons can lead them tailor their approach. It prospective feedback our operative theatre.

متن کاملAnalysis of the petrous portion of the internal carotid artery: landmarks for an endoscopic endonasal approach.
OBJECTIVES/HYPOTHESIS While there are many benefits to the endoscopic endonasal approach to the infratemporal fossa, involvement of the petrous portion of the internal carotid artery (ICA) poses a unique challenge. The endoscopic endonasal approach requires establishing the relationship of the petrous ICA to anatomical landmarks to guide the surgeon. This study evaluates the relationship of pet...
