“…MR might also be beneficial in plastic and reconstructive surgery due to the ability to project holographic visualizations of anatomical structures onto the patient to guide reconstruction. An example of this was a study [ 47 ] into auricular reconstruction, in which an image of the contralateral auricle was projected onto the ipsilateral surgical site. After appropriate positioning was ensured, MR resulted in improved perceived reconstructive results compared to a conventional approach with transparent film guidance [ 47 ].…”

Background Mixed reality (MR) and its potential applications have gained increasing interest within the medical community over the recent years. The ability to integrate virtual objects into a real-world environment within a single video-see-through display is a topic that sparks imagination. Given these characteristics, MR could facilitate preoperative and preinterventional planning, provide intraoperative and intrainterventional guidance, and aid in education and training, thereby improving the skills and merits of surgeons and residents alike. Objective In this narrative review, we provide a broad overview of the different applications of MR within the entire spectrum of surgical and interventional practice and elucidate on potential future directions. Methods A targeted literature search within the PubMed, Embase, and Cochrane databases was performed regarding the application of MR within surgical and interventional practice. Studies were included if they met the criteria for technological readiness level 5, and as such, had to be validated in a relevant environment. Results A total of 57 studies were included and divided into studies regarding preoperative and interventional planning, intraoperative and interventional guidance, as well as training and education. Conclusions The overall experience with MR is positive. The main benefits of MR seem to be related to improved efficiency. Limitations primarily seem to be related to constraints associated with head-mounted display. Future directions should be aimed at improving head-mounted display technology as well as incorporation of MR within surgical microscopes, robots, and design of trials to prove superiority.

“…The position of the auricle on the healthy side and the auricle on the affected side in patients with microtia was often inconsistent, and some patients were accompanied by maxillofacial deformity (13). Meanwhile, in clinical practice, plastic surgeons cannot find an effective way to accurately locate the reconstructed auricle (14). Therefore, accurately locating the position of reconstructed auricle has always been a difficult problem for plastic surgeons (15,16).…”

Background: Congenital microtia is a common congenital disease in children, the cause of which is still unclear. At present, the main treatment for congenital microtia is ear reconstruction. Accurately locating of the reconstructed ear on the affected side before ear reconstruction surgery is difficult, while it is the key of successful operation. Our ear reconstruction team has developed a novel method to accurately locate the reconstructed auricle. This novel method has achieved good results in clinical practice.Methods: Thirty patients with unilateral ear reconstruction, who underwent auricle reconstruction using our invented auricle reconstruction positioning method in the Plastic Surgery Hospital of Chinese Academy of Medical Sciences from January 2020 to July 2021, were enrolled in this study.Results: Through Wilcoxon signed rank test, we found that there was no statistical difference between the mean distance from the highest point of the patient's normal ear to the central axis of the nose and that from the highest point of the reconstructed ear to the central axis of the nose (P>0.05). Meanwhile, there was no statistical difference between the mean distance from the lowest point of the patient's normal ear to the central axis of the nose and that from the lowest point of the reconstructed ear to the central axis of the nose (P>0.05).The satisfaction rate of patients and their families to the location of the reconstructed auricle was 100%. Conclusions:The novel method of locating the reconstructed auricle employs simple materials. The implementation process is easy, and the effect is significant. To a certain extent, it solves the difficulty of locating the reconstructed auricle in ear reconstruction operation. Although this method can only be applied to patients with unilateral microtia, we recommend it for locating the reconstructed auricle by every plastic surgeon.

“…After auricular reconstruction, the reconstructed and normal contralateral auricle should have the same size and position. 10 Therefore, the accurate positioning of the reconstructed auricle preoperatively is essential. Auricular reconstruction is based on the experience of the surgeon and is subjective and uncontrollable.…”
