“…Patient-specific surgical planning based on individual anatomical characteristics is an important element in current and future neurosurgery. [20][21][22][23][24] In brain tumor surgery, all patients have different tumors, in terms of size, location, extent, and characteristics, and thus personalized surgical plans are required for each patient. Despite using the most advanced neuronavigation systems for neurosurgery, neurosurgeons still require a lot of experience and training to derive an idea of the 3D reconstruction of lesions and structures from 2D data using their imagination.…”

OBJECTIVE With the advancement of 3D modeling techniques and visualization devices, augmented reality (AR)–based navigation (AR navigation) is being developed actively. The authors developed a pilot model of their newly developed inside-out tracking AR navigation system. METHODS The inside-out AR navigation technique was developed based on the visual inertial odometry (VIO) algorithm. The Quick Response (QR) marker was created and used for the image feature–detection algorithm. Inside-out AR navigation works through the steps of visualization device recognition, marker recognition, AR implementation, and registration within the running environment. A virtual 3D patient model for AR rendering and a 3D-printed patient model for validating registration accuracy were created. Inside-out tracking was used for the registration. The registration accuracy was validated by using intuitive, visualization, and quantitative methods for identifying coordinates by matching errors. Fine-tuning and opacity-adjustment functions were developed. RESULTS ARKit-based inside-out AR navigation was developed. The fiducial marker of the AR model and those of the 3D-printed patient model were correctly overlapped at all locations without errors. The tumor and anatomical structures of AR navigation and the tumors and structures placed in the intracranial space of the 3D-printed patient model precisely overlapped. The registration accuracy was quantified using coordinates, and the average moving errors of the x-axis and y-axis were 0.52 ± 0.35 and 0.05 ± 0.16 mm, respectively. The gradients from the x-axis and y-axis were 0.35° and 1.02°, respectively. Application of the fine-tuning and opacity-adjustment functions was proven by the videos. CONCLUSIONS The authors developed a novel inside-out tracking–based AR navigation system and validated its registration accuracy. This technical system could be applied in the novel navigation system for patient-specific neurosurgery.

“…Based on the evaluation completed in [45], better visualization techniques which differentiate between arteries and veins and ascertain the absolute depth of a vessel of interest are required for more complicated anomalies such as arteriovenous malformations (AVM) and arteriovenous fistulae (AVF); however, AR is favourable technology in neuro-vascular surgery. To conclude, there is no universal method for reporting navigation accuracy in augmented reality neuro-navigation; comparative studies, however, still need to be assessed to identify its effectiveness [49].…”

Augmented Reality in Surgical Navigation: A Review of Evaluation and Validation Metrics

Pre-operative imaging has been used earlier to guide traditional surgical navigation systems. There has been a lot of effort in the last decade to integrate augmented reality into the operating room to help surgeons intra-operatively. An augmented reality (AR) based navigation system provides a clear three-dimensional picture of the interested areas over the patient to aid surgical navigation and operations, which is a promising approach. The goal of this study is to review the application of AR technology in various fields of surgery and how the technology is used for its performance in each field. Assessment of the available AR assisted navigation systems being used for surgery is reviewed in this paper. Furthermore, a discussion about the required evaluation and validation metric for these systems is also presented. The paper comprehensively reviews the literature since the year 2008 for providing relevant information on applying the AR technology for training, planning and surgical navigation. It also describes the limitations which need to be addressed before one can completely rely on this technology for surgery. Thus, additional research is desirable in this emerging field, particularly to evaluate and validate the use of AR technology for surgical navigation.

“…Such extended surgical durations not only predispose patients to significant fluctuations in body temperature but also require maintaining a fixed position for extended periods. 1,2 This immobility, in turn, exerts sustained pressure on specific areas of the skin, particularly those overlying bony prominences, leading to localized damage. The cumulative effect of these factors significantly heightens the risk of developing pressure ulcers during the surgical process, presenting a notable challenge in the perioperative management of neurosurgical patients.…”

Pressure injuries are a significant concern for patients undergoing neurosurgical procedures due to prolonged immobility and the complexity of care. This study evaluates the efficacy of standardized pressure ulcer management protocols in preventing pressure injuries and enhancing patient care in a neurosurgical context. A comprehensive retrospective analysis was conducted at a single institution from December 2020 to December 2023, comparing 50 patients who received standardized pressure ulcer management (intervention group) with 50 patients who received conventional care (control group). The study assessed the incidence of pressure ulcers, patient comfort levels using the Kolcaba Comfort Scale and sleep quality using the Richards‐Campbell Sleep Questionnaire (RCSQ). Statistical analysis was performed using SPSS software, version 27.0, applying t‐tests and chi‐square tests as appropriate. The intervention group exhibited a significantly lower incidence of pressure ulcers at all measured time points post‐surgery compared to the control group. Patient comfort levels in the intervention group were consistently higher across psychological, environmental, physiological and socio‐cultural domains. Sleep quality metrics, including sleep depth, latency to sleep onset and overall sleep quality, were significantly improved in the intervention group. The implementation of standardized pressure ulcer management protocols in neurosurgical care significantly reduces the incidence of pressure injuries, enhances patient comfort and improves sleep quality. These findings highlight the importance of adopting structured care protocols to improve postoperative outcomes and patient well‐being in neurosurgical settings.
