“…As the display is miniaturised and semi-transparent, the wearer is able to perform real world tasks while having simultaneous access to visual and audio information. There is much interest in the potential use of head-mounted displays in medicine and especially in medical education, with multiple proposed applications including hands-free recording of images and videos [1,2,3], augmented reality or remote assistance during surgery [4,5,6,7,8], remote clinic review [7] and concurrent viewing of live imaging during practical procedures [9,10].…”

Abstract:In the context of surgical navigation systems based on augmented reality (AR), the key challenge is to ensure the highest degree of realism in merging computer-generated elements with live views of the surgical scene. This paper presents an algorithm suited for wearable stereoscopic augmented reality video see-through systems for use in a clinical scenario. A video-based tracking solution is proposed that relies on stereo localization of three monochromatic markers rigidly constrained to the scene. A PnP-based optimization step is introduced to refine separately the pose of the two cameras. Video-based tracking methods using monochromatic markers are robust to non-controllable and/or inconsistent lighting conditions. The two-stage camera pose estimation algorithm provides sub-pixel registration accuracy. From a technological and an ergonomic standpoint, the proposed approach represents an effective solution to the implementation of wearable AR-based surgical navigation systems wherever rigid anatomies are involved.

“…Therefore, numerous researchers are focusing on the development of AR-based surgical navigation system, and some pilot studies in the field of OMFS have been reported. For example, Badiali et al (2014) presented a head-mounted system offering augmented reality information to the surgeons [60]. During the augmented-reality assisted LeFort1 maxillary repositioning, the virtual planning was overlaid on a real patient which was a significantly useful strategy for the operators.…”

Introduction: Currently, oral and maxillofacial surgery (OMFS) still poses a significant challenge for surgeons due to the anatomic complexity and limited field of view of the oral cavity. With the great development of computer technologies, he computer-aided surgery has been widely used for minimizing the risks and improving the precision of surgery.Areas covered: The major goal of this paper is to provide a comprehensive reference source of current and future development of computer-aided OMFS including surgical planning, simulation and navigation for relevant researchers.Expert commentary: Compared with the traditional OMFS, computer-aided OMFS overcomes the disadvantage that the treatment on the region of anatomically complex maxillofacial depends almost exclusively on the experience of the surgeon.
