■评估一种新颖的虚拟现实(VR)工具,旨在增强对有资格进行DCR手术的患者的鼻解剖结构的理解。
■获得轨道的术前计算机断层扫描(CT)扫描,并作为DICOM(医学数字成像和通信)文件加载到D2P软件(3DSystemsInc.Littleton,CO)用于组织分割和3D模型制备。在几个解剖结构上进行了分割,包括头骨,泪囊,鼻中隔,下鼻甲和中鼻甲。使用VR耳机可视化所得的3D模型。完成分割程序后,由六名外科医生组成的小组评估了十例病例,包括来自耳鼻喉科和眼塑专科的高级和住院医师。
■所检查的数据集包括来自符合Endo-DCR的患者的眼眶的10个术前CT扫描的图像。当使用VR工具评估CT时,在73.3%的病例中,耳鼻喉科外科医生是正确的,而只有43.3%的眼科医生是正确的(卡方,p=.018)。在72.8%的病例中,耳鼻喉科外科医生被评估为正确的隔膜偏离,而只有47.2%的眼科医生是正确的(卡方,p=.094)。当使用VR工具评估CT时,在60%的案例中,顾问对病理学是正确的,而57.7%的居民是正确的(卡方,p=.853)。在81.7%的案例中,顾问被评估为有隔膜偏离,而只有58.3%的眼科医生是正确的(卡方,p=.198)。
■耳鼻喉科外科医生,以及顾问,CT的解释比眼科医生和住院医师更好。令人惊讶的是,VR系统并不能帮助他们更好地解释CT.Further,应进行更广泛的研究,以建立一个VR系统,该系统有助于在DCR手术前以及DCR手术期间对术前CT的正确解释.
UNASSIGNED: To assess a novel Virtual Reality (VR) tool designed to enhance understanding of the nasal anatomy in patients eligible for DCR surgery.
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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.
