Abstract

Purpose: To assess a novel Virtual Reality (VR) tool designed to enhance understanding of the nasal anatomy in patients eligible for DCR surgery.

Methods: Preoperative Computed Tomography (CT) scans of the orbit were obtained and loaded as DICOM (Digital Imaging and Communications in Medicine) files onto the D2P software (3D Systems Inc. Littleton, CO) for tissue segmentation and 3D model preparation. Segmentation was performed on several anatomical structures, including the skull, lacrimal sac, nasal septum, inferior and middle turbinate. The resulting 3D model was visualized using a VR headset. After completing the segmentation procedure, ten cases were evaluated by a panel of six surgeons, including both senior and resident physicians from ENT and oculoplastic specialties.

Results: The dataset under examination comprised images from 10 preoperative CT scans of the orbits of patients eligible for Endo-DCR. When evaluating the CT using the VR tool, in 73.3% of the cases ENT surgeons were right about the side of pathology, while only 43.3% ophthalmologists were right (chi-square, p = .018). In 72.8% of the cases ENT surgeons were evaluated right that there is a septum deviation, while only in 47.2% of the cases the ophthalmologists were right (chi-square, p = .094).When evaluating the CT using the VR tool, in 60% of the cases consultants were right about the pathology, while 57.7% of the residents were right (chi-square, p = .853). In 81.7% of the cases consultants were evaluated right that there is a septum deviation, while only in 58.3% of the cases the ophthalmologists were right (chi-square, p = .198).

Discussion: ENT surgeons, as well as consultants, interpreted the CT better than the ophthalmologists and residents. Surprisingly, the VR system did not help them to interpret the CT better. Further, more extensive studies should be done to build a VR system that assists in the correct interpretation of the preoperative CT before DCR surgery as well as during DCR surgery.

利用虚拟现实技术进行 DCR 手术的术前规划。

目的：评估一种新型虚拟现实（VR）工具，该工具旨在增强符合 DCR 手术条件的患者对鼻腔解剖结构的了解：方法：获得术前眼眶计算机断层扫描（CT），并将其作为 DICOM（医学数字成像和通信）文件加载到 D2P 软件（3D Systems Inc.对多个解剖结构进行了分割，包括颅骨、泪囊、鼻中隔、下鼻甲和中鼻甲。生成的三维模型通过 VR 头显进行可视化。完成分割程序后，由六名外科医生组成的小组对十个病例进行了评估，其中包括耳鼻喉科和眼部整形专业的资深医生和住院医生：检查的数据集包括符合 Endo-DCR 术前 CT 扫描条件的 10 例患者眼眶的图像。在使用 VR 工具评估 CT 时，73.3% 的病例中耳鼻喉外科医生对病变侧的判断是正确的，而只有 43.3% 的病例中眼科医生的判断是正确的（chi-square，p = .018）。在 72.8% 的病例中，耳鼻喉科外科医生对鼻中隔偏曲的评价是正确的，而只有 47.2% 的病例中眼科医生的评价是正确的（卡方，p = .094）。在使用 VR 工具评价 CT 时，60% 的病例中顾问对病理的评价是正确的，而 57.7% 的住院医生的评价是正确的（卡方，p = .853）。在 81.7% 的病例中，顾问对鼻中隔偏曲的评估是正确的，而只有 58.3% 的病例中眼科医生的评估是正确的（卡方，p = .198）：讨论：耳鼻喉科外科医生和顾问对 CT 的解释优于眼科医生和住院医生。令人惊讶的是，VR 系统并不能帮助他们更好地解读 CT。此外，还应该进行更广泛的研究，以建立一套 VR 系统，协助正确解读 DCR 手术前和 DCR 手术过程中的术前 CT。
