Application of 3D Visualization Technology in Preoperative Planning of Giant Goiter

Abstract

Background and Objectives: 3D visualization technology provides a more intuitive visual virtual reality surgical presentation for preoperative simulation planning, inhand visualization operation and accurate postoperative assessment in surgical procedures, but there is a lack of evidence to support whether this technology is more advantageous in preoperative planning of giant goiter. The aim of this study was to investigate the value of 3D visualization technology in the preoperative planning of giant goiter. Methods:The clinical data of eight patients with giant goiter admitted to the First People's Hospital of Anhui University of Technology for general surgery from October 2020 to August 2022 were retrospectively analyzed. The image data were imported into 3D visualization software (3D Slicer software) in DICOM format for 3D reconstruction to analyze the 3D positional relationship between the giant thyroid nodules and the surrounding tissues and organs, to perform preoperative simulation operations, and to develop precise surgical pathways.Results: All patients were operated according to the optimal plan selected by the simulation operation, and the actual surgical procedure conformed to the preoperative simulation plan 100%, and all of them successfully completed the total resection of giant thyroid nodules without any perioperative death and no new symptoms appeared after the operation. Conclusion:The use of 3D visualization technology in the preoperative planning of giant goiter can accurately obtain 3D anatomical information of the lesion and its adjacent tissues, select the optimal surgical path, and reduce surgical risks, which is of great clinical guidance value in guiding the preoperative precise surgical planning of giant goiter.
