The application ratio of 3D high-definition and 2D-4K ultra-high-definition endoscopic systems in trans-nose subcranial surgery

Yoichi Uozumi of Neurosurgery, Kobe University School of Medicine, Japan, and others analyzed the differences in characteristics between 3D-high-definition and 2D-4K ultra-high-definition endoscopy systems, as well as their respective advantages in clinical surgery, and compared them with conventional 2D standard-definition endoscopy systems, and published the results in the September 2020 issue of the journal Operation Neurosurgery.
- excerpted from the chapter of the article , Ref: Uozumi Y, et al. Opera Neurosurg (Hagerstown). 2020 Sep 1;19 (3):281-287. doi: 10.1093/ons/opz426.Research background Since the on-the-lens surgery on the base of the nose, efforts have been made to improve stereoscopic visual quality.
3D-High Definition (3D HD) and 2D-4K Ultra-High Definition (2D-4K HD) by Yoichi Uozumi of Neurosurgery, Kobe University School of Medicine, Japan, etc. The differences in characteristics between mirror systems and their respective advantages in clinical surgery were compared with conventional 2D standard definition (2D SD) endoscopic systems, and the results were published in the September 2020 issue of the journal Operation Neurosurgery.
the retrospective study selected newly diagnosed patients with Knosp grade 0 to 3 pituitary adenomas, 74 of whom were surgically performed after the introduction of 3D HD or 2D-4K HD endoscopy systems in July 2017 and 12 who started using conventional 2D SD endoscopic systems in March 2016.
endoscopic nasal subcranial surgery process can be divided into three stages in the nose, butterfly bone and epidural, comparing the duration of each stage of surgery, and assessing the time and accuracy of stitching the epidural at the bottom of the saddle.
3D HD endoscope system offers the advantage of operating in the nasal cavity, providing intuitive depth perception for shallow-to-deep surgery.
2D-4K HD provides superior image quality, ensuring that surgeons can perform microsurgery operations similar to open transcranial surgery, providing an advantage in the epidural stage (Figures 1, 2).
3D HD and 2D-4K HD endoscopes are significantly shorter than 2D SD endoscopes for in-nasal surgery.
from the application of 2D SD endoscopes to 2D-4K HD endoscopes and 3D HD endoscope systems, this order shortens the time and accuracy of the epidural epidural stitching at the bottom of the saddle.
1. In-surgery images of spinal cord tumors using 3D HD endoscopes; tiny bulges in the bottom of the saddle that have been extensively damaged by the lesions can be seen, helping to operate in the right direction.
2. Intraoperative photographs of a craniofacial tube tumor with a 2D-4K HD endoscope;
Conclusions In summary, in nasal subcranial surgery, 3D HD endoscopic operation should be selected in the nasal intracranial stage, while the use of 2D-4K HD endoscopic system in the epidural stage is more advantageous.
, 3D HD and 2D-4K HD endoscope systems are significantly superior to traditional 2D SD endoscope systems.
authors believe that the quality of stereoscopic visual images provided by various endoscope systems is different, so suitable endoscopic systems should be selected for different surgical scenes.
