Abstract:
Objective To construct the digital pituitary adenoma image and explore the value of simulation of single nostril-transsphenoidal surgery.Methods Thirty patients with pituitary adenoma,admitted to our hospital from October 2009 to March 2011,were performed single nostril-transsphenoidal surgery; thin slice images of preoperative examinations included computed tomography and magnetic resonance imaging were imported into Dextroscope workstation to construct digital pituitary adenoma image; the related anatomic structures of surgical approach were observed and the procedures were formulated and performed.Results Models based on three-dimensional shapes could show the related anatomical structures dynamically and stereoscopically and simulate the operation processrepeatedly.The preoperative planning indicators in the anatomic segment of nasal,anterior sphenoidal wall,basilar pituitary fossa and structures around the tumor were completed.The anatomic characteristics of simulated surgery were consistent with the real operation.Conclusions The digital models can provide some individual anatomic information to develop the preoperative planning programs for single nostril-transsphenoidal surgery,which can facilitate the work of operation and avoid injuring the important anatomical structures.
