“…Accuracy of the registration between virtual content and the real scene is reported to be in the order of millimetres or less in recent VR/ AR applications to surgery. 30,[32][33][34][35] The required accuracy for most advanced radiotherapy techniques is of the same order of magnitude. 31 A reduction of the registration error from 5-10 mm to 1-2 mm has been achieved from 2002 29 to the present date.…”

“…Kim et al 33 developed a dual surgical navigation system for endoscopic surgery that used VR and AR techniques together to obtain additional depth and visual information for organs. The VR environment was developed to visualise the spatial relationships among the target organs, endoscope and surgical tools.…”

Purpose: We review augmented (AR) and virtual reality (VR) applications in radiotherapy as found in the scientific literature and highlight future developments enabled by the use of small mass-produced devices and portability of techniques developed in other fields to radiotherapy.Analysis: The application of AR and VR within radiotherapy is still in its infancy, with the notable exception of training and teaching applications. The relatively high cost of equipment needed to generate a realistic 3D effect seems one factor that has slowed down its use, but also the sheer amount of image data is relatively recent, were radiotherapy professionals are only beginning to explore how to use this to its full potential. This increased availability of 3D data in radiotherapy will drive the application of AR and VR in radiotherapy to efficiently recognise and extract key features in the data to act on in clinical decision making. Conclusion:The development of small mass-produced tablet devices coming on the market will allow the user to interact with computer-generated information more easily, facilitating the application of AR and VR. The increased connectivity enabling virtual presence of remote multidisciplinary team meetings heralds significant changes to how radiotherapy professionals will work, to the benefit of our patients.

Background: One of the mechanisms that cause tip fold-over is a misalignment between the electrode array’s coiling direction and the cochlea’s curving direction. Objectives: We reviewed surgical videos and computed tomography (CT) datasets of the patients who underwent cochlear implantation procedures from January 2010 to December 2021, paying particular attention to the cochlea’s orientation in the surgeon’s microscopic view. Methods: CT dataset and video recordings were analyzed to measure the “slope angle,” which is the angle between the cochlea’s coiling plane and the horizontal plane. Results: There were 220 cases that met the criteria and completed the analysis. The mean slope angle was 12.1° ± 9.5°, with a minimum of −9.4° and maximum of 44.6°. However, each surgeon had a favored slope angle range. Conclusion: Understanding the slope angle and making an effort to reduce the chance of misalignment during electrode insertion may help prevent tip fold-over of slim perimodiolar electrode arrays.
