“…To our knowledge, the current study explored for the first time to show these structures in three dimensions and there has been considerable interest in rendering 2D images into 3D images that more closely mimic the surgical environment of the sellar area. Image reconstruction of normal anatomical structures has been employed for surgical training and preoperative planning, including transsphenoidal surgery [2].…”

“…Therefore, blindness or massive bleeding and even minimal damage to surrounding structures during an operation can lead to an irrevocable outcome [2]. Several important surgical landmarks, such as recesses, prominences, and impressions caused by neurovascular structures coursing underneath the bone, could be clues to locate these vital structures, which help avoid injury during the operation.…”

The relationship between the volume of sphenoid sinus (SS) and the prevalence of internal carotid artery (ICA) and optic nerve (ON) protrusions in the SS was studied by using high-resolution CT imaging. The ICA and ON protrusions in SS were observed in randomly selected normal head CT scanning images from 350 adult subjects. According to the incidence of ICA protrusion, three groups were divided into no ICA protrusion (70.75%), unilateral protrusion (8.68%) and bilateral protrusions (20.57%). The ON protrusion accounted for 16% in 350 subjects and accompanied absolutely with ICA protrusion, but ICA protrusion appeared without accompanying with ON protrusion. The SS volume depended upon the protrusions in it and showed statistical differences, without ICA protrusion, the smallest size (11.16 ± 1.60) cm 3 ; the unilateral protrusion, medium size (14.20 ± 1.80) cm 3 and the bilateral protrusion, the largest size (25.03 ± 2.21) cm 3 . By observing 3D reconstructed models of ON and SS, we found ON was adjacent to SS (46%) and to posterior ethmoid sinuses (44%). The current study indicates that SS volume is varied with numbers of the protrusions and that ON location varies with the pneumatization of SS. Our results provide an anatomical basis to the surgeries for SS and its surrounding structures.

“…Whilst the models developed for these studies were anatomically accurate, they did not clearly represent the visual and aesthetic qualities of the structures. There are reports of models that have been developed using CT (Keedy et al, 2011;Wang, Xue, Jing, & Wang, 2012) and MRI scans (Hu, Wilson, Ladak, Haase, & Fung, 2009;Kockro et al, 2015;Metzler et al, 2012;Nguyen, Nelson, & Wilson, 2012;Nicholson, Chalk, Funnell, & Daniel, 2006;Wang et al, 2012). However, very few studies have been able to create both accurate and photorealistic anatomy models.…”

Consumer-grade virtual reality has recently become available for both desktop and mobile platforms and may redefine the way that students learn. However, the decision regarding which device to utilise within a curriculum is unclear. Desktop-based VR has considerably higher setup costs involved, whereas mobile-based VR cannot produce the quality of environment due to its limited processing power. This study aimed to compare performance in an anatomical knowledge test between two virtual reality headsets, the Oculus Rift and Gear VR, as well as to investigate student perceptions and adverse health effects experienced from their use. An identical lesson on spine anatomy was presented to subjects using either the Oculus Rift or Gear VR, with no significant differences observed in test scores from participants using either device, with both groups answering 60% of the questions correctly. However, 40% of participants experienced significantly higher rates of nausea and blurred vision when using the Gear VR (P < 0.05). It was established that the more cost effective mobile-based VR was just as suitable for teaching isolated-systems than the more expensive desktop-based VR. These outcomes show great promise for the effective use of mobile-based virtual reality devices in medical and health science education.

“…Thus, the vital structures of the optic nerve and the internal carotid artery become visible after removing the lateral wall of sphenoid sinus. 3 Identification of the sphenopalatine artery, V2, and the foramen rotundum is important during dissection of the pterygopalatine fossa. 4 Nevertheless, attention should be given to the horizontal distance to the posterior part of the vomer.…”
