Abstract:
Objective：To investigate the application value of 3D reconstruction technique based on 3D Slicer software in endoscopic transsphenoidal surgery for pituitary adenoma.Methods:From October 2017 to March 2019,70 patients with pituitary adenoma treated in department of neurosurgery,Affiliated Hospital of Xuzhou Medical University,were randomly divided into two groups:Preoperative reconstruction group and traditional surgical group.In the preoperative reconstruction group,the image processing software 3D Slicer was used to reconstruct the bone markers of sellar region,pituitary tumor,internal carotid artery and optic nerve structure before operation,and the preoperative planning was carried out.In order to evaluate the degree of reduction of 3D reconstructed images,the anatomical signs of sellar region displayed by 3D reconstruction were compared with the operative field images under endoscopy.The traditional surgical group did not perform three-dimensional reconstruction and performed the operation according to the routine procedure.The operative time,intraoperative bleeding volume,postoperative hospital stay and incidence of postoperative complications of reconstruction group were compared with those of traditional surgical group.Results:The complete display rates of superior turbinate,middle turbinate and nasal septum were 100% by 3D reconstruction and endoscopy.The complete display rates of 3D reconstruction for sphenoid sinus ostium,optic protuberance，carotid protuberance and optico-carotid recess were 100%,88%，94%and 94%,respectively,which were significantly higher than those of endoscopy (P＜0.05).The operative time,intraoperative bleeding volume,postoperative hospitalization time and the incidence of intraoperative cerebrospinal fluid leakage in the reconstruction group were better than those in the traditional surgical group (P＜0.05),however,there was no significant difference between the two groups in the incidence of optic nerve injury,internal carotid artery injury,postoperative cerebrospinal fluid leakage and postoperative urinary avalanche (P＞0.05).Conclusion:The 3D reconstruction technology based on 3D Slicer has high reducibility and accuracy in the display of saddle floor anatomical marks,which is helpful to predict the surgical scene in advance and carry out surgical teaching.At the same time,for medical institutions without intraoperative navigation,the accuracy and safety of operation can be improved to a certain extent,and the incidence of complications can be reduced.
