title: Internal carotid artery in the operative plane of endoscopic endonasal transsphenoidal surgery.
abstract: The objective of this study was to measure the related parameters of intercarotid artery (ICA) in the operative plane of endonasal transsphenoidal approach for hypophyseal surgeries. Nine parameters of the ICA were examined in the computed tomographic angiographic (CTA) scan of 101 patients. The shortest distance between the middle point of the nasal columella and the projective point of the ICA (D(3)) was 85.50 (5.79) mm. The shortest distance between the anterior wall of the sphenoid sinus and the projective point of the ICA (D(4)) was 16.93 (3.50) mm. The distance between the bilateral projective points of the ICA (D(5)) was 21.60 (3.45) mm. The shortest distance from the anterior wall of the sphenoid sinus to the line between the bilateral projective points of the ICA (D(6)) was 12.1 (3.91) mm. The shortest distance between the middle point of nasal columella and the anterior wall of the sphenoid sinus (D(7)) was 72.67 (5.99) mm. The width of the angle between the bilateral ICA projective point from the middle point of the nasal columella (A(1)) was 14.9 (2.32) degrees. The width of the angle between the bilateral ICA projective points from the anterior-most point of sphenoid sinus (A(2)) was 85.49 (18.12) degrees. Clinically, it is relatively safe to work within the distances and angles measured in this research, and these results may provide information for clinical surgery of pituitary tumor.
