The Montreal Augmentation Mammaplasty Operation (MAMO) Simulator: An Alternative Method to Train and Assess Competence in Breast Augmentation Procedures

Validation of a simulator for oncoplastic breast conserving surgery

BACKGROUND

Therapeutic Mammoplasty (TM) is increasingly becoming the standard of care, especially for patients with large tumor-to-breast volume ratios. The wider dissemination of oncoplastic skills warrants systems for the acquisition and assessment of safe skills. To date, TM simulations have not been developed for the acquisition or assessment of oncoplastic skills. This study aimed to design, develop, and validate a synthetic TM simulator for specialist surgical training and assessment.

METHODS

A prospective, observational, and survey-based study. Breast surgeons collaborated with designers to construct a TM simulator. A modified Delphi approach was used to create a Competency Assessment Tool (CAT). Surgeons with varying operative experience performed simulated vertical scar TM. Procedures were videotaped (blinded, pseudo-anonymized), subsequently reviewed, and independently rated against CAT by three experts. Specimen radiographs and volumetric analysis were performed to assess specimen weight(g), volume(cm3), and adequacy of resection, derived as a percentage of deviation in uniformity around a 10 mm margin.

RESULTS

Thirty participants were recruited (10 consultants, 10 senior registrars (ST7-8), and 10 junior registrars (ST3-6)). Video-based rating scores (0-40) were significantly greater in consultants (median(IQR) = 34.0(30.5-38.0)) than in senior registrars (median(IQR) = 30.0(28.0-33.0)) and junior registrars (median(IQR) = 28.0(25.8-30.3)). The CAT scores varied significantly based on operator grade (p < 0.05). The inter-rater reliability showed fair agreement (κ = 0.379). Specimens resected by consultants had significantly greater weight and volume (p < 0.05). The consultants demonstrated the greatest uniformity in resection accuracy (p < 0.05).

CONCLUSION

A novel oncoplastic simulator was developed to practice and assess TM skills. Video-based ratings and end-product assessments differentiated experts from novice surgeons, suggesting construct validity.

A Systematic Review of Simulation-Based Training Tools in Plastic Surgery

OBJECTIVES

The recent shift from traditional surgical teaching to the incorporation of simulation training in plastic surgery has resulted in the development of a variety of simulation models and tools. We aimed to assess the validity and establish the effectiveness of all currently available simulators and tools for plastic surgery.

DESIGN

Systematic review.

METHODS

The PRISMA 2020 checklist was followed. The review protocol was prospectively registered in PROSPERO (CRD42021231546). Published and unpublished literature databases were searched to the 29th of October 2023. Each model was appraised in accordance with the Messick validity framework, and a rating was given for each section. To determine the effectiveness of each model, the McGaghie model of translational outcomes was used.

RESULTS

On screening 1794 articles, 116 were identified to discuss validity and effectiveness of simulation models in plastic surgery. These were hand surgery (6 studies), breast surgery (12 studies), facial surgery (25 studies), cleft lip and palate surgery (29 studies), rhinoplasty (4 studies), hair transplant surgery (1 study), surgery for burns (10 studies), and general skills in plastic surgery (29 studies). Only 1 model achieved an effectiveness level > 3, and no model had a rating > 2 in all aspects of the Messick validity framework.

CONCLUSION

There are limited models enabling the transfer of skills to clinical practice. No models achieved reductions in surgical complications or costs. There must be more validity studies conducted using updated validity frameworks, with an increased emphasis on the applicability of these simulators to improve patient outcomes and surgical technique. More training tools evaluating both technical and non-technical surgical skills are recommended.

Training in oncoplastic surgery for mastologists

OBJECTIVE

The radical change in the treatment of breast cancer has promoted the necessity for more comprehensive training of the professionals involved, ensuring the preservation of oncological safety while also allowing for cosmetic interventions to benefit breast cancer survivors. The aim of this study was to present the methods employed in the training of breast surgeons, highlighting the importance of oncoplasty and breast reconstruction.

METHODS

A literature review was conducted in two databases, identifying articles related to medical education in the context of oncoplastic surgery and breast reconstruction. We also assessed the Brazilian experience in oncoplastic centers.

RESULTS

The basis for educational discussions was derived from 16 articles. We observed approaches that included hands-on courses utilizing simulator models, porcine models, cadaver labs, and fellowship programs. Positive outcomes were observed in Brazil, a fact based on seven oncoplasty training centers for senior mastologists and five training centers for junior mastologists. From 2009 to 2023, an estimated 452 seniors and 42 juniors received training, representing approximately 30% of mastologists in Brazil who have acquired training and experience in oncoplasty.

CONCLUSION

Despite the limited number of publications on training methods, oncoplastic centers have made significant progress in Brazil, establishing a successful model that can be replicated in other countries.

A systematic review of surgical simulation in gender affirmation surgery

The burgeoning field of gender affirmation surgery (GAS) has become increasingly complex, challenging plastic surgeons to meet high standards for their patients. During the COVID-19 pandemic, the emphasis on remote learning ushered in the increased use of surgical simulation training, offering residents the opportunity to trial challenging procedures before treating patients. This systematic review seeks to summarize current simulation training models used in GAS. A systematic review was conducted according to PRISMA-P guidelines using the following databases: PubMed, Medline, Scopus, Embase, Web of Science, and Cochrane. Inclusion criteria were English-language peer-reviewed articles on surgical simulation techniques or training related to the field of gender surgery. Skills and techniques taught and assessed, model type, equipment, and cost were abstracted from articles. Our search criteria identified 1650 articles, 10 of which met the inclusion criteria for data extraction. Simulation models included those that involved cadavers (n = 2), synthetic benchtop (n = 5), augmented/virtual reality (n = 2), and 3D-printed interfaces (n = 1). The most common procedure involved breast or pectoral reconstruction and/or augmentation (n = 5), followed by vaginal reconstruction (n = 3). One simulation model involved facial GAS. All models focused on surgical technique and anatomy, three on suture skills or knot-tying, and one on surgical decision-making. The evolving field of GAS requires that plastic surgery trainees be knowledgeable on surgical techniques surrounding this scope of practice. Surgical simulation not only teaches residents how to master techniques but also helps address the sensitive nature of GAS.

Development and Validation of a Laryngeal Microsurgery Simulation Training System for Otolaryngology Residents

OBJECTIVE

This study aims to create a synthetic laryngeal microsurgery simulation model and training program; to assess its face, content, and construct validity; and to review the available phonomicrosurgery simulation models in the literature.

STUDY DESIGN

Nonrandomly assigned control study.

SETTING

Simulation training course for the otolaryngology residency program at Pontificia Universidad Católica de Chile.

METHODS

Resident (postgraduate year 1 [PGY1]/PGY2) and expert groups were recruited. A laryngeal microsurgery synthetic model was developed. Nine tasks were designed and assessed through a set of programmed exercises with increasing difficulty, to fulfill 5 surgical competencies. Imperial College Surgical Assessment Device sensors applied to the participants' hands measured time and movements. The activities were video-recorded and blindly assessed by 2 laryngologists using a specific and global rating scale (SRS and GRS). A 5-point Likert survey assessing validity was completed by experts.

RESULTS

Eighteen participants were recruited (14 residents and 4 experts). Experts performed significantly better than residents in the SRS (p = .003), and GRS (p = .004). Internal consistency was demonstrated for the SRS (α = .972, p < .001). Experts had a shorter execution time (p = .007), and path length with the right hand (p = .04). The left hand did not show significant differences. The survey assessing validity resulted in a median 36 out of 40 points score for face validity; and 43 out of 45 points score, for global content validity. The literature review revealed 20 available phonomicrosurgery simulation models, only 6 with construct validity.

CONCLUSION

The face, content, and construct validity of the laryngeal microsurgery simulation training program were established. It could be replicated and incorporated into residents' curricula.

Defining Cognitive Competencies for Breast Augmentation Surgery

BACKGROUND

Breast augmentation is the most performed aesthetic procedure in the United States yet one that surgical trainees have limited exposure to. This creates a lack of confidence in performing this key procedure among graduates. It is imperative to develop novel curricula and objective measures to standardize acquiring competency.

OBJECTIVE

This qualitative study establishes various cognitive competencies and pitfalls in augmentation mammoplasty.

METHODS

Using a priori established task analysis, literary sources and operative observations, a total of 20 cognitive vignettes were developed to conduct cognitive task analyses (CTA) for breast augmentation through semistructured interviews of experts. Interviews were itemized, and verbal data were recorded, transcribed verbatim, and thematically analyzed by reviewers.

RESULTS

Eight experts were interviewed (median age 39 years, 87.5% males, with a median of 7 years in practice). A conceptual framework for breast augmentation was developed and divided into 5 operative stages containing 208 competencies and 41 pitfalls. Pitfalls were mapped to deficits in shared decision making, proper informed consent, prospective hemostasis, and awareness of anatomical landmarks and markings.

CONCLUSIONS

This work provided an inclusive framework of cognitive competencies in breast augmentation surgery to facilitate their assessment. This model guides the analysis of other procedures to transfer cognitive competencies to learners. In a transition toward competency-based education, this provides a primer to assessments that include all aspects of a surgeon's skill set.

A Description of Breast Models Used to Teach Clinical Skills

Background: Health care trainees lack opportunities to practice breast assessment and clinical skills with patients, making breast models significant for hands-on training. Insufficient training leads to low competence across practitioners in breast health areas of practice, including clinical lactation. The aim of this review was to describe types of breast models used to teach clinical skills of the breast across breast health areas. The secondary aims were to describe education interventions that included each model and identify whether multiple skin tones were available in models. Methods: Authors conducted a scoping review to identify which types of breast models are used to teach clinical skills across breast health areas of practice and determine gaps in literature regarding how clinical lactation skills are taught. The literature search was conducted in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, MedLine, and ProQuest. Inclusion criteria were students/professionals engaging in breast model simulation. Eighteen studies were reviewed. Authors extracted data on participants, breast health area, breast model, intervention, evaluation, general outcomes, skin tone, and research design. Results: The most common skill area was clinical breast exam (n = 7), while least was breastfeeding education (n = 1). Most models were commercial (n = 12). Zero studies described skin tone. Generally, breast model simulations were correlated with increased clinical skills and confidence regardless of model used. Conclusions: Despite demonstrated gain of skills, this review reveals inconsistent use of breast models and evaluation, exclusion of diverse skin tones, and lack of breast models reported to teach clinical lactation skills.

Septoplasty Training During the COVID-19 Era: Development and Validation of a Novel Low-Cost Simulation Model

OBJECTIVE

In a context of increasingly limited surgical exposition, enhanced by the coronavirus disease 2019 (COVID-19) pandemic context, the objective of this article is to explain the development of a novel low-cost and simple replication animal-based septoplasty training model for otolaryngology residents, to assess its face and construct validity, and to validate a specific rating scale for each task.

STUDY DESIGN

Experimental study.

SETTING

Surgical simulation laboratory.

METHODS

Septoplasty experts divided the procedure into key tasks. A simulator model to perform tasks was developed using pig ears to imitate human nasal septum cartilage, and a Specific Rating Scale was constructed. Trainees and faculty performed all tasks in the model. The participants were videotaped, and operative time, hand movements, and path length were recorded using a motion sensor device. Two blinded experts evaluated the videos with Global and Specific Rating Scales. All participants answered a satisfaction survey.

RESULTS

Fifteen subjects were recruited (7 trainees and 8 faculty). Significantly higher Global Rating Scale score, shorter operative time and path length, and fewer hand movements were observed in the faculty group. The satisfaction survey showed high applicability to a real scenario (mean score of 4.6 out of 5). Specific Rating Scale showed construct and concurrent validity and high reliability.

CONCLUSION

This simulation model and its specific rating scale can be accurately used as a validated surgical assessment tool for endonasal septoplasty skills. Its low cost and simple replicability make it a potentially useful tool in any otolaryngology surgical training program.

Simulation in plastic and reconstructive surgery: a scoping review

Since the origins of surgery, simulation has played an important role in surgical education, particularly in plastic and reconstructive surgery. This has greater relevance in contemporary settings of reduced clinical exposure resulting in limited work-based learning opportunities. With changing surgical curricula, it is prescient to examine the role of simulation in plastic and reconstructive surgery.

A scoping review protocol was used to identify relevant studies, with an iterative process identifying, reviewing and charting the data to derive reported outcomes and themes.

Of the 554 studies identified, 52 studies were included in this review. The themes identified included simulator modalities, curriculum elements targeted and relevant surgical competencies. There was a predominance of synthetically based simulators, targeting technical skills largely associated with microsurgery, paediatric surgery and craniomaxillofacial surgery.

Existing simulators largely address high-complexity procedures. There are multiple under-represented areas, including low-complexity procedures and simulation activities addressing communication, collaboration, management and leadership. There are many opportunities for simulation in surgical education, which requires a contextual appreciation of educational theory. Simulation may be used both as a learning method and as an assessment tool.

This review describes the literature relating to simulation in plastic and reconstructive surgery and proposes opportunities for incorporating simulation in a broader sense, in the surgical curriculum.

A Systematic Review of Aesthetic Surgery Training Within Plastic Surgery Training Programs in the USA: An In-Depth Analysis and Practical Reference

BACKGROUND

The importance of aesthetic surgery exposure for plastic and reconstructive trainees has been recently validated by the expansion of case requirements for aesthetic procedures from 50 to 150, as well as resident-driven desire for increased cosmetic exposure throughout training. We aim to systematically review the literature at a national level to report on overall trends in aesthetic surgery training within PRS residencies.

METHODS

A literature search of PubMed, Embase, and Scopus identified all English articles published in the USA between 2000 and 2020, using a combination of "aesthetic surgery", "cosmetic surgery", "plastic surgery", "residency and internship", "education", and "training."

RESULTS

Our initial search resulted in 415 articles. After review of inclusion and exclusion criteria, in addition to cross-referencing, 41 studies remained, including 15 studies discussing resident and/or program director surveys, eight studies discussing teaching methods, sixteen studies discussing dedicated resident clinics, four studies discussing cosmetic/aesthetic fellowships, three studies discussing cosmetic practice patterns, and eleven studies discussing patient outcomes.

CONCLUSION

Current literature demonstrates that there are gaps in aesthetic surgery training for PRS residents in the USA, including facial and neck surgeries and non-surgical interventions. Resident clinics have clear benefits for resident education, without sacrificing patient outcomes. Residency programs should consider the development of a resident cosmetic clinic and/or dedicated cosmetic center to increase surgical exposure and increase trainee comfort in providing this subset of procedures. Published literature is limited in consistency of methods of evaluation, and further in-depth analysis of case volume and diversity at training programs within the USA and internationally is indicated.

Toward Competency-Based Training: To What Extent Are We Competency-Based?

BACKGROUND

Time-based training models in plastic surgery vary in exposure, resulting in low confidence levels among graduates. The evolution of postgraduate medical education into a competency-based model to address these issues requires an understanding of interventions described in the plastic surgery literature to identify gaps and guide creation of assessments to demonstrate competence.

METHODS

A systematic search of the MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, PubMed, and Cochrane databases from inception until December of 2017 was conducted using search terms and synonyms of educational interventions reported in plastic surgery. Full texts were retrieved following filtering and data extracted were related to intervention design and execution, involvement of competency assessment, and educational objectives and alignment to Accreditation Council for Graduate Medical Education competencies and Royal College of Physicians and Surgeons of Canada Canadian Medical Education Directives for Specialists roles. Study quality was assessed using Kirkpatrick's levels of learning evaluation, validity evidence, and the Medical Education Research Study Quality Instrument score.

RESULTS

Of the initial 4307 results, only 36 interventions met the inclusion criteria. Almost all interventions aligned to medical knowledge and patient care Accreditation Council for Graduate Medical Education competencies. One-fifth of the interventions involved no assessment of competency, whereas most displayed assessment at the level of design as opposed to outcomes. Quality assessment revealed low levels of learning evaluation and evidence of validity; the average Medical Education Research Study Quality Instrument score was 10.9 of 18.

CONCLUSION

A systematic review of educational literature in plastic surgery was conducted to assess the quality of reported educational interventions, and to help guide creating tools that ensure competency acquirement among trainees.

The role of simulation in training breast surgeons: a systematic review

BACKGROUND

As surgical education has evolved, most curricula have favoured a competency-based approach over traditional apprenticeship models. Surgical simulation can be a useful aide in the training of both oncological and reconstructive breast surgery trainees. This review investigates the extent to which simulation of breast surgery procedures has been validated as a training tool.

METHODS

A comprehensive literature search for studies evaluating the objective validity of breast surgery simulators was performed, using MEDLINE, EMBASE and the Cochrane Library databases. Studies assessing construct, concurrent or predictive validity were included, as well as those demonstrating skill acquisition.

FINDINGS

The initial literature search returned 1,625 hits, with only five articles meeting the inclusion criteria. Simulators were designed to train procedures such as breast augmentation, lesion biopsy and excision. Of these, breast biopsy was the most simulated procedure (three studies). Two studies evaluated animal models, two evaluated synthetic models and one study assessed both a synthetic and animal model. Construct validity was confirmed in two studies, concurrent validity in one study and a learning curve demonstrated in another study. No association between experience and performance was seen in the remaining study. The quality of the evidence presented in each article was low due to numerous limitations. Despite the abundance of breast surgery simulators created for trainees, few have been objectively validated and they only cover a narrow range of breast procedures. Although early results are promising, further studies are required before routine use of simulators is considered in breast surgery curricula.

Use of Simulation in Plastic Surgery Training

The nationwide focus on patient safety and the health of residents has increased the demand for educational tools outside the operating room. Simulation is a valuable tool for assessing and developing surgical skills in a controlled and safe environment. The use of simulation as a formal component of training has been increasing in various surgical subspecialties. In general surgery, simulation examinations such as the Fundamentals of Laparoscopic Surgery and Fundamentals of Endoscopic Surgery have become a prerequisite to board certification. Although formal simulation examinations in plastic surgery are not universal, there has been an increase in the use of simulation to increase resident competency in the operating room. For now, we will review the current state of simulation in craniofacial, hand, microvascular, and esthetic surgery and discuss applications for the future. We will also discuss the evolving role of artificial intelligence, virtual reality, and augmented reality in plastic surgery training and testing.

Aesthetic Training in Plastic Surgery Residency

Training in aesthetic surgery is a core element in a plastic surgery residency program. Nevertheless, in the past, many studies have shown the lack of resident confidence in aesthetic procedures upon graduation. In recent years, a number of efforts have been made to address this concern, including increasing the required residency aesthetic case requirements and the integration of resident aesthetic clinics to increase exposure and independence in this aspect of training. Numerous studies have been conducted to evaluate the efficacy of these resident-run clinics and have substantiated their value as an important educational tool in residency training and validated their safety in patient care. In fact, survey studies have shown that though residents today show a markedly increased confidence in their training when compared with the past, they still feel there is room for improvement in areas such as facial and minimally invasive surgeries, along with procedures that require higher patient volume to refine. In this article, we review the current state of aesthetic surgery training during plastic surgery residency and discuss future directions in the field.
