Virtual Reality to Improve the Experience of the Mohs Patient-A Prospective Interventional Study

Apple Vision Pro and Its Implications in Mohs Micrographic Surgery: A Narrative Review

Mohs micrographic surgery (MMS) is a precise and effective technique for treating skin cancers, necessitating high accuracy and real-time decision-making to ensure complete tumor removal while preserving healthy tissue. The introduction of the Apple Vision Pro (AVP), an advanced mixed-reality headset, presents a potential technological advancement in surgical practice. The present investigation explores the integration of AVP into Mohs surgery, focusing on its potential to enhance preoperative planning, intraoperative guidance, and postoperative analysis. The AVP's high-resolution displays, advanced eye-tracking technology, and real-time data overlay capabilities may assist in meticulous surgical planning and execution. In the preoperative phase, AVP enables the creation and manipulation of detailed 3D models, providing comprehensive visualizations of tumor margins and critical structures. During surgery, AVP's real-time data overlay aids in precise tumor excision and spatial orientation, reducing errors and improving outcomes. Postoperatively, the AVP facilitates detailed procedural reviews and serves as a robust educational tool for surgical trainees. Despite its promising applications, challenges such as real-time resolution limitations, potential eye strain from prolonged use, and high costs must be addressed for widespread clinical adoption. This review highlights the transformative potential of AVP in Mohs surgery and underscores the need for further research to optimize integration and maximize benefits in dermatological procedures.

Augmented and Virtual Reality Applications in Facial Plastic Surgery: A Scoping Review

OBJECTIVES

Augmented reality (AR) and virtual reality (VR) are emerging technologies with wide potential applications in health care. We performed a scoping review of the current literature on the application of augmented and VR in the field of facial plastic and reconstructive surgery (FPRS).

DATA SOURCES

PubMed and Web of Science.

REVIEW METHODS

According to PRISMA guidelines, PubMed and Web of Science were used to perform a scoping review of literature regarding the utilization of AR and/or VR relevant to FPRS.

RESULTS

Fifty-eight articles spanning 1997-2023 met the criteria for review. Five overarching categories of AR and/or VR applications were identified across the articles: preoperative, intraoperative, training/education, feasibility, and technical. The following clinical areas were identified: burn, craniomaxillofacial surgery (CMF), face transplant, face lift, facial analysis, facial palsy, free flaps, head and neck surgery, injectables, locoregional flaps, mandible reconstruction, mandibuloplasty, microtia, skin cancer, oculoplastic surgery, rhinology, rhinoplasty, and trauma.

CONCLUSION

AR and VR have broad applications in FPRS. AR for surgical navigation may have the most emerging potential in CMF surgery and free flap harvest. VR is useful as distraction analgesia for patients and as an immersive training tool for surgeons. More data on these technologies' direct impact on objective clinical outcomes are still needed.

Exploring the potential role for extended reality in Mohs micrographic surgery

Mohs micrographic surgery (MMS) is a cornerstone of dermatological practice. Virtual reality (VR) and augmented reality (AR) technology, initially used for entertainment, have entered healthcare, offering real-time data overlaying a surgeon's view. This paper explores potential applications of VR and AR in MMS, emphasizing their advantages and limitations. We aim to identify research gaps to facilitate innovation in dermatological surgery. We conducted a PubMed search using the following: "augmented reality" OR "virtual reality" AND "Mohs" or "augmented reality" OR "virtual reality" AND "surgery." Inclusion criteria were peer-reviewed articles in English discussing these technologies in medical settings. We excluded non-peer-reviewed sources, non-English articles, and those not addressing these technologies in a medical context. VR alleviates patient anxiety and enhances patient satisfaction while serving as an educational tool. It also aids physicians by providing realistic surgical simulations. On the other hand, AR assists in real-time lesion analysis, optimizing incision planning, and refining margin control during surgery. Both of these technologies offer remote guidance for trainee residents, enabling real-time learning and oversight and facilitating synchronous teleconsultations. These technologies may transform dermatologic surgery, making it more accessible and efficient. However, further research is needed to validate their effectiveness, address potential challenges, and optimize seamless integration. All in all, AR and VR enhance real-world environments with digital data, offering real-time surgical guidance and medical insights. By exploring the potential integration of these technologies in MMS, our study identifies avenues for further research to thoroughly understand the role of these technologies to redefine dermatologic surgery, elevating precision, surgical outcomes, and patient experiences.

Best Practices for Research in Virtual and Augmented Reality in Dermatology

Virtual reality (VR) and augmented reality (AR) technologies have advanced rapidly in recent years. These cutting-edge technologies provide dermatology researchers, educators, proceduralists, and patients with opportunities in new scientific horizons. VR is a technology that facilitates immersive human experiences by allowing users to connect with various simulated environments through natural head and hand movements, whereas AR supplements a user's perception of their real environment with virtual elements. Despite technological advancements, there is limited literature on the methodological steps for conducting rigorous VR and AR research in dermatology. Effective storyboarding, user-driven design, and interdisciplinary teamwork play a central role in ensuring that VR/AR applications meet the specific needs of dermatology clinical and research teams. We present a step-by-step approach for their design, team composition, and evaluation in dermatology research, medical education, procedures, and habit formation strategies. We also discuss current VR and AR dermatology applications and the importance of ethical and safety considerations in deploying this new technology.

Efficacy and Safety of Anxiolytics in Mohs Micrographic Surgery: A Randomized, Double-Blinded, Placebo-Controlled Trial

BACKGROUND

Patient anxiety can complicate surgical outcomes by elevating blood pressure, increasing the need for postoperative pain management, and reducing overall patient satisfaction. Despite the use of anxiolytic medications in outpatient procedures, there is limited comparative evidence on the efficacy and safety of these agents in Mohs micrographic surgery.

OBJECTIVE

To compare the effectiveness and safety of different preprocedural anxiolytic agents in Mohs surgery on perioperative patient anxiety and patient satisfaction.

MATERIALS AND METHODS

A double-blinded, randomized, placebo-controlled trial was conducted of 6 different preprocedural anxiolytic agents (lorazepam, diazepam, alprazolam, gabapentin, pregabalin, and melatonin) in 350 patients undergoing Mohs surgery. Anxiety and vital signs were recorded.

RESULTS

Diazepam demonstrated a statistically significant, sustained reduction in anxiety levels compared with placebo ( p = .03). Gabapentin significantly reduced early anxiety ( p = .02). Alprazolam showed a trend to early anxiety reduction ( p = .08). Lorazepam ( p = .73), pregabalin ( p = .53), and melatonin ( p = .24) failed to reduce patient anxiety compared with placebo at any time point. No anxiolytic significantly impacted any patient vital sign or cognition.

CONCLUSION

Although short-acting benzodiazepines and gamma-aminobutyric acid medications may have transient anxiolytic effects, a single oral dose of 5 mg of diazepam can provide a sustained anxiolytic effect in Mohs surgery, with excellent patient safety.

Pain Management in Dermatology

BACKGROUND

The dermatologist has to deal with many situations where the patient feels pain and must therefore know how to manage it.

SUMMARY

The aim of this review was to explore the treatments available to manage pain in dermatology in different circumstances, with an emphasis on pharmacological and non-pharmacological interventions specifically studied in dermatology.

Analysis of Factors Contributing to Perioperative Mohs Micrographic Surgery Anxiety: Patient Survey Study at an Academic Center

BACKGROUND

High perioperative patient anxiety is predictive of worse postoperative pain and quality of life. Several Mohs micrographic surgery (MMS) patient characteristics influence anxiety; however, the contributions of certain factors remain uncertain.

OBJECTIVE

Investigate factors influencing perioperative MMS patient anxiety, especially those with debated impact or unclear data.

METHODS

The authors surveyed 145 adult patients receiving MMS performed by a single MMS surgeon from 2018 to 2020. Patients self-reported demographics, history, and 10-point visual analog scale anxiety assessments at multiple stages. Health care provider (HCP)-perceived anxiety assessments were queried. A stepwise multiple regression modeling approach was used to explore potential factors.

RESULTS

Younger age, female sex, and a self-reported history of anxiety confirmed by prior HCP diagnosis were significant predictors of pre-MMS anxiety. Postoperative anxiety increased with more layers removed and higher pre-MMS anxiety. HCP-perceived patient anxiety increased with younger patient age, more layers removed, prior skin cancer removal, and HCP-perceived pre-MMS patient anxiety.

CONCLUSION

Anxiety-reducing interventions should target young female patients with a history of HCP-diagnosed anxiety, and patients with more layers removed. Prior skin cancer removal is associated with increased HCP-perceived intraoperative patient anxiety; however, it is not significant for patient-reported anxiety. Pre-MMS consultation may not be effective for anxiety reduction.

Dermatological Conditions Inducing Acute and Chronic Pain

Pain is a common condition in dermatology. The aim of this review is to analyse the characteristics of pain in dermatology. Some skin diseases are conventionally known to cause pain; e.g. ulcers, pyoderma gangrenosum and herpes zoster. Common dermatoses, such as psoriasis or atopic dermatitis, can also cause significant pain. Some conditions are characterized by neuropathic pain and/or pruritus, without visible primary lesions: e.g. the neurocutaneous diseases, including small fibre neuropathies. Patients often fear pain in skin surgery; however, surgical procedures are rather well tolerated and any pain is mainly due to administration of local anaesthetic. Some therapies may also be uncomfortable for the patient, such as photodynamic therapy or aesthetic procedures. Thus, pain in dermatology is common, and its aetiology and characteristics are very varied. Knowledge of the different situations that cause pain will enable dermatologists to propose suitable analgesic solutions.

Contemplating or Acting? Which Immersive Modes Should Be Favored in Virtual Reality During Physiotherapy for Breast Cancer Rehabilitation

Background

Even though virtual reality (VR) is more and more considered for its power of distraction in different medical contexts, the optimal conditions for its use still have to be determined in order to design interfaces adapted to therapeutic support in oncology.

Objective

The objective of this study was to examine the benefits of VR using two immersion methods (i.e., one participatory, one contemplative) and comparing them with each other in a population of women with breast cancer who have undergone breast surgery, during scar massage sessions.

Methods

In a physiotherapy center, each patient participated in four experimental conditions in a random order: two sessions used virtual immersion (i.e., one participatory and one contemplative), one session proposed musical listening and the fourth one was a standard session care. The impact of the level of patient involvement in the virtual world was apprehended through the evaluation of the feeling of presence; the estimation of elapsed time of the physiotherapy sessions and particular attention was paid to the evaluation of patient emotional state.

Results

Our study showed an increase in positive emotions (i.e., joy and happiness) and a decrease in anxiety regardless which support methods were offered. Participatory VR created a feeling of more intense spatial presence.

Conclusion

Our results highlight the importance of the context in which VR should be offered. The presence of the practitioner and his interactions with the patient can provide a context just as favorable in reducing anxiety as the emotional regulation tools used (VR, music). The use of technological tools should be favored when the practitioner is unavailable during the treatment phase or, even, in order to reduce the monotonous nature of repetitive therapeutic sessions.

A Virtual Reality Game to Change Sun Protection Behavior and Prevent Cancer: User-Centered Design Approach

Background

Public health sun safety campaigns introduced during the 1980s have successfully reduced skin cancer rates in Australia. Despite this success, high rates of sunburn continue to be reported by youth and young adults. As such, new strategies to reinforce sun protection approaches in this demographic are needed.

Objective

This study aims to develop a virtual reality (VR) game containing preventive skin cancer messaging and to assess the safety and satisfaction of the design based on end user feedback.

Methods

Using a two-phase design approach, we created a prototype VR game that immersed the player inside the human body while being confronted with growing cancer cells. The first design phase involved defining the problem, identifying stakeholders, choosing the technology platform, brainstorming, and designing esthetic elements. In the second design phase, we tested the prototype VR experience with stakeholders and end users in focus groups and interviews, with feedback incorporated into refining and improving the design.

Results

The focus groups and interviews were conducted with 18 participants. Qualitative feedback indicated high levels of satisfaction, with all participants reporting the VR game as engaging. A total of 11% (2/8) of participants reported a side effect of feeling nauseous during the experience. The end user feedback identified game improvements, suggesting an extended multistage experience with visual transitions to other environments and interactions involving cancer causation. The implementation of the VR game identified challenges in sharing VR equipment and hygiene issues.

Conclusions

This study presents key findings highlighting the design and implementation approaches for a VR health intervention primarily aimed at improving sun protection behaviors. This design approach can be applied to other health prevention programs in the future.

Effect of Virtual Reality Therapy in Reducing Pain and Anxiety for Cancer-Related Medical Procedures: A Systematic Narrative Review

CONTEXT

Virtual reality (VR) has emerged as a novel form of nonpharmacological analgesia therapy. We wished to review the use of VR to treat pain and anxiety in cancer-related medical procedures and chemotherapy.

OBJECTIVES

To determine if immersive VR influences pain and/or anxiety outcomes in patients with cancer undergoing medical interventions. To discuss critical limitations in the current evidence base and provide suggestions for future areas of research.

METHODS

A systematic review was performed on Ovid MEDLINE, PubMed, and Google Scholar from 1999 to December 2019. The following search terms were run in each of the databases: Virtual Reality and pain or anxiety. Articles were assessed by two independent authors for inclusion.

RESULTS

From 999 retrieved citations, nine studies met inclusion criteria for review. Methodological limitations and small sample sizes preclude strong guidance for clinical applications. Although studies demonstrated a trend toward improvement in pain and anxiety, only two studies reached statistical significance.

CONCLUSION

There is inconclusive evidence on the significance of immersive VR in reducing pain (five studies) or anxiety (six studies) for patients with cancer undergoing medical interventions or receiving chemotherapy. Further research on the effect of immersive VR as a tool for medical procedures and/or patients with cancer undergoing treatment is required.

Virtual reality can reduce anxiety during office-based great saphenous vein radiofrequency ablation

OBJECTIVE

Office-based treatment of venous pathology is common and frequently involves the use of anxiolytic medication to reduce anxiety. Virtual reality (VR) has been shown to effectively reduce pain and anxiety in a variety of settings. The objective of the present study was to determine whether VR could be smoothly integrated into office-based vascular procedures and to ascertain whether VR could reduce procedural pain or anxiety.

METHODS

A total of 40 patients undergoing an office-based endovenous radiofrequency ablation were included in the present study. Of the 40 patients, 20 were randomized to the VR group and 20 to the control group. The patients in the VR group were equipped with a Samsung GearVR headset and headphones (Samsung, Suwon, South Korea) running AppliedVR software (AppliedVR Inc, Los Angeles, Calif), which ran throughout the duration of the procedure. All 40 patients underwent unilateral great saphenous vein radiofrequency ablation. After the procedure, the patients were surveyed regarding their preprocedure anxiety and their pain and anxiety during the procedure using the Wong-Baker scale.

RESULTS

All procedures were successfully completed, and all patients were generally satisfied with their treatment. The average procedure time was not significantly different. No statistically significant differences were present in preprocedure anxiety or procedural pain between the two groups. The anxiety level during the procedure, however, was 4.09 of 10 in the control group vs 2.95 of 10 in the VR group, statistically significant difference using a paired t test. Furthermore, the anxiety level for the control group had increased during the procedure but that of the VR group had decreased. Finally, 85% of the patients in the VR group would recommend using VR to someone undergoing a similar procedure.

CONCLUSIONS

VR can be safely and efficiently integrated into office-based vascular procedures. VR was generally well liked and recommended by those who used it. Most importantly, our findings suggest that VR can decrease procedural anxiety. Further research should examine whether this might obviate the need for anxiolytic medication.

BET 2: Is virtual reality effective in reducing adult pain perception during medical procedures?

A short-cut review of the available medical literature was carried out to establish whether virtual reality was an effective method for pain control during medical procedures. After abstract review, fifteen papers were found to answer this clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. It is concluded that there is insufficient high-quality research to answer this question.
