The Application of Three-Dimensional Technology Combined With Image Navigation in Nasal Skull Base Surgery

Abstract

Three-dimensional (3D) technology including 3D reconstruction and 3D printing technology, has been widely used in clinical treatment, especially in surgical planning, and image navigation technology, which can make surgical procedures more accurate, now is also increasingly favored by surgeons. But the combination of those 2 technologies was rarely reported. Thus, this study will preliminarily investigate the feasibility and the effect of the combination of 2 technologies in endonasal skull base surgery. Eight patients were involved in this study (from October 2016 to July 2017 at The Affiliated Hospital of Qingdao University), 5 cases of nasal skull base tumors and 3 cases of foreign body perforation. All operations were done under the assistance of 3D technology and image guidance system. Surgical discussion with patient, preoperative planning and clinical teaching were investigated between 2D images and 3D models by voting. For all cases, 3D reconstruction model and 3D printed model were deemed to be more helpful than CT/MRI images in surgical discussion with the patient; surgical simulation on 3D model in preoperative planning was largely deemed to be helpful and very helpful; and in clinical teaching, 3D models combined with image guidance system were deemed to be more helpful in understanding the disease than using 2D images. Besides, all patients recovered well after surgery, no recurrence and complications were found in the follow-up. The combination of 3D technology and electromagnetic image guidance system could improve surgical efficiency and the quality of clinical teaching.

Application of Three-Dimensional Image Reconstruction Technology in Neurogenic Intestinal Nursing Tasks

“…e 3D image reconstruction theory plays a typical role in di erent professional elds. Related elds mainly include medical surgery [1], model reconstruction [2], ultrasound propagation [3], three-dimensional pixels [4], etc. In the eld of medical donor image reconstruction, the existing medical donor image reconstruction needs a large amount of data, and the data cannot better re ect the original shape of the medical donor, there were some problems such as poor accuracy.…”

Computer assisted skull base surgery: a contemporary review

“…The application of endoscopy and computed tomography (CT) in the 1970s improved surgical planning and accuracy [ 5 ], [ 6 ], [ 7 ], [ 8 ]. In the late 1990s the introduction of surgical planning software, 3D printing, and intraoperative navigation/CT expanded the scope of skull base surgery to include the entire anterior and middle cranial fossa [ 9 ], [ 10 ], [ 11 ], [ 12 ], [ 13 ], [ 14 ], [ 15 ], [ 16 ], [ 17 ], [ 18 ], [ 19 ], [ 20 ], [ 21 ], [ 22 ]. More recent refinements in intraoperative navigation and CT have resulted in decreased operative times and improved clinical outcomes [ 13 , 14 , 23 ].…”
