Abstract:
Objective To observe the anatomical structure via endonasal transsphenoidal approach with virtual endoscopy (VE) and explore the clinical applications of VE in endoscopic pituitary tumor resection through the endonasal transsphenoidal approach. Methods The VE was applied to the reconstruction of the pre-surgical 64-slice CT scanning of the 21 patients with pituitary adenoma received the endoscopic endonasal transsphenoidal surgery. A comparative study and a correlation analysis of cumulative scores of the anatomical structure were performed between the reconstructed VE images and the intraoperative endoscopic ones. Results Preoperative VE images and intraoperative endoscope images are very similar. The correlation of cumulative scores of the anatomical structure between the VE images of anatomical findings and the intraoperative images was positively noted (r=0.923, P=0.001),indicating that VE can be applied to simulately observe the anatomical structure before the endoscopic endonasal transsphenoidal pituitary surgery, and observe the anatomical structure through the endonasal transsphenoidal approach. Conclusion Being able to display the important anatomical structure and its varieties before the endoscopic endonasal transsphenoidal pituitary surgery, VE proves to be a valuable approach to the preoperative planning, increases the surgical efficiency and improves the safety of the surgery.
