Abstract:
Objective To investigate the related anatomical parameters of single-nostril transsphenoidal approach in adults.Methods Two hundred and ninty-four adults,performed head-neck CTA in our hospital from October 2011 to January 2012,were prospectively collected; and their CT data were collected,and the following anatomical parameters were measured through the multi-planar reconstruction of the CTA images:the angle of sella lowest point-anterior nasal spine root-the bottom of nasal cavity (∠ 1),the angle of the connection of Maxillary central incisors bottom to auditory canal crossing with the bottom of nasal cavity(∠ 2),the angle of tuberculum sellae-anterior nasal spine root-the bottom of nasal cavity(∠3),the angle ofdorsum sellae-anterior nasal spine root-the bottom of nasal cavity (∠4),and the angles of right / left sphenoid sinus mouth-maxillary ridge-the bottom of nasal cavity(∠5 / ∠6).Results ∠1(29.7±3.1°),∠2(29.5±3.1°),∠3(33.6±3.8°),∠4(28.8±3.6°),∠5(33.9±4.2°) and ∠6(33.6±4.5°) were calculated; significant differences were noted between each two angles (P＜0.05); ∠ 1 and ∠2 had a positive linear correlation (r=0.78,P＜0.05).Conclusion Preoperative multi-planar reconstruction images of CT facilitates safe opening of the anterior wall of spheniodal sinus and the sellar floor,and the operative position refers to the orientation that the virtual plane of Maxillary central incisors bottom to bilateral auditory canal erects the ground.
