Augmented Reality Microsurgery: Proof of Concept for a Novel Approach to Microsurgical Field Visualization in Plastic Surgery.

BACKGROUND: Microsurgery is conducted on tiny anatomical structures such as blood vessels and nerves. Over the past few decades, little has changed in the way plastic surgeons visualize and interact with the microsurgical field. New advances in augmented reality (AR) technology present a novel method for microsurgical field visualization. Voice- and gesture-based commands can be used in real time to adjust the size and position of a digital screen. Surgical decision support and/or navigation may also be used. The authors assess the use of AR in microsurgery. METHODS: The video feed from a Leica Microsystems OHX surgical microscope was streamed to a Microsoft HoloLens2 AR headset. A fellowship-trained microsurgeon and three plastic surgery residents then performed a series of four arterial anastomoses on a chicken thigh model using the AR headset, a surgical microscope, a video microscope (or "exoscope"), and surgical loupes. RESULTS: The AR headset provided an unhindered view of the microsurgical field and peripheral environment. The subjects remarked on the benefits of having the virtual screen track with head movements. The ability of participants to place the microsurgical field in a tailored comfortable, ergonomic position was also noted. Points of improvement were the low image quality compared with current monitors, image latency, and the lack of depth perception. CONCLUSIONS: AR is a useful tool that has the potential to improve microsurgical field visualization and the way surgeons interact with surgical monitors. Improvements in screen resolution, latency, and depth of field are needed.

Impact of ACAPS Coordinated Interview Release Policy: Applicant and Program Attitudes, Adherence, and Interview Trends.

BACKGROUND: The authors studied the impact of a new, coordinated interview release date for integrated plastic surgery residencies. METHODS: A cross-sectional study of all 2020 integrated plastic surgery residencies and applicants was performed. Voluntary, anonymous surveys were administered following implementation of the interview policy. RESULTS: Program response rates were 55.6% for the initial survey and 57.1% for the follow-up survey. Programs released an average of 2.1 (95% CI, 1.8 to 2.4) rounds of interview invitations and invited 39.0 (95% CI, 35.3 to 42.6) applicants to interview. Policy adherence was high (91.1%). Most programs believed the interview policy was an improvement for applicants (46.5% yes; 9.1% no) and programs (41.9% yes; 27.0% no). Median rank of matched candidates was 13, and 55.1% of programs matched candidates within the top quartile of their rank list. The average candidate applied to 72 programs, attended 11 interviews, and ranked 12 programs. Interview distribution was bimodal, with peaks at six and 15 total interview invitations. Applicants within the top fifth, tenth, and fifteenth percentile for total interview invites disproportionately accounted for 15.3%, 26.6%, and 36.5%, respectively, of all invitations received. Survey data suggested applicant satisfaction with travel planning, improved scheduling, and cost savings following implementation of the interview policy. Applicants were somewhat dissatisfied with interview distribution. CONCLUSIONS: A coordinated interview release date is facile to adopt and does not adversely impact program interview trends or match rates. Applicants benefit from improved scheduling, travel planning, and cost savings; however, interview distribution continues to favor top-tier candidates.

An Analysis of Gender Bias in Plastic Surgery Resident Assessment.

BACKGROUND: Previous studies have shown men and women attending physicians rate or provide operating room (OR) autonomy differently to men and women residents, with men attendings providing higher ratings and more OR autonomy to men residents. Particularly with the advent of competency-based training in plastic surgery, differential advancement of trainees influenced by gender bias could have detrimental effects on resident advancement and time to graduation. OBJECTIVE: We determined if plastic surgery residents are assessed differently according to gender. METHODS: Three institutions' Operative Entrustability Assessment (OEA) data were abstracted from inception through November 2018 from MileMarker, a web-based program that stores trainee operative skill assessments of CPT-coded procedures. Ratings are based on a 5-point scale. Linear regression with postgraduate year adjustment was applied to all completed OEAs to compare men and women attendings' assessments of men and women residents. RESULTS: We included 8377 OEAs completed on 64 unique residents (25% women) by 51 unique attendings (29% women): men attendings completed 83% (n = 6972; 5859 assessments of men residents; 1113 of women residents) and women attendings completed 17% (n = 1405; 1025 assessments of men residents; 380 of women residents). Adjusted analysis showed men attendings rated women residents lower than men residents (P < .001); scores by women attendings demonstrated no significant difference (P = .067). CONCLUSIONS: Our dataset including 4.5 years of data from 3 training programs showed men attendings scored women plastic surgery residents lower than their men counterparts.

Differences in operative self-assessment between male and female plastic surgery residents: A survey of 8,149 cases.

BACKGROUND: Previous studies show female residents tend to underrate and male residents to overrate their own performance. We sought to determine if plastic surgery resident trainee self-evaluations differ by resident sex. METHODS: We extracted Operative Entrustability Assessment (OEA) data for plastic surgery programs from MileMarker™, a program capable of storing assessment data for CPT-coded procedures. Complete OEAs contain a trainee self-assessment and attending surgeon assessment. We used simple statistics and linear regression to assess differences, stratifying by trainee sex and post-graduate year (PGY). RESULTS: We analyzed 8149 OEAs from 3 training programs representing 64 residents (25% female) and 51 attendings. Compared to attending assessments, both male and female residents significantly underrated their performance during PGY1. However, during PGY2-6 male residents' self-evaluations were significantly higher and female residents' self-evaluations significantly lower than their attending evaluations. CONCLUSIONS: Results demonstrated female plastic surgery residents underestimated and male residents overestimated their performance. Further studies are needed to determine reasons for these differences.

Assessing the Correlation Between a Surgeon's Ability to Draw a Procedure and Ability to Perform the Procedure.

OBJECTIVES: The ability to assess a trainee's technical skill in a manner that maintains patient safety is critical to resident education. To do so, senior plastic surgery educators frequently ask residents to draw their proposed operation, presuming that a surgeon's ability to perform a surgery is reflected in his or her ability to diagram the procedure, independent of artistic ability. The purpose of this study was to delineate the relationship between the ability to draw a surgical procedure and execute it in a simulated model, and to determine if the ability to draw a procedure depends on artistic ability. DESIGN: Participants in varying levels of knowledge and surgical skill were asked to draw a 4-strand cruciate tendon repair and subsequently perform the procedure on a validated, simulated model. The participants were graded according to Objective Structured Assessment of Technical Skills scales by 2 blinded hand surgeon examiners. Statistical analysis was performed in SAS 9.4 with Spearman's rank correlation coefficient. SETTING: The study was performed at Baylor Scott and White Health in Temple, TX in an office-based laboratory setting. Participants Forty participants comprised of senior medical students, plastic/orthopedic surgery residents, and plastic/hand surgery attendings. All 40 participants entered and completed the study. RESULTS: A statistically significant strongly positive correlation was found between overall assessment of drawing and overall assessment of performing the surgical procedure (p = 0.004). At the same time, the assessment of ability to draw the procedure was not associated with a general ability to draw or previous art training (p = 0.28). CONCLUSIONS: Our findings support the use of drawing a specific procedure as an assessment tool to evaluate a surgeon's ability to perform a procedure.

Outcomes of Corticosteroid Treatment for Trigger Finger by Stage.

BACKGROUND: Although steroid injection remains a common first-line treatment of trigger finger, clinical experience suggests that not all cases of trigger finger respond the same. The purpose of this study was to use a classification system for trigger finger that is simple and reproducible, and produces clearly definable, clinically relevant cutoff points to determine whether responsiveness to steroid injection correlates to clinical staging. METHODS: The authors conducted a prospectively collected longitudinal study of trigger finger patients separated into four stages of severity. Each subject received a single injection of 6 mg of dexamethasone acetate. One-month outcomes were analyzed to evaluate the efficacy of steroid injection. These outcomes were further stratified based on baseline characteristics and stage of triggering. RESULTS: A total of 99 digits and 69 subjects were included. Two variables were found to be significant in predicting response to initial injection: (1) multiple affected digits and (2) stage severity. Patients with multiple involved fingers were 5.8 times more likely to have no resolution of symptoms compared with those with a single affected finger. For every level of stage increase, the odds doubled for having no resolution of symptoms. CONCLUSIONS: Steroid injection remains a viable first-line option for patients presenting with mild triggering (stage 1 and 2). For more severe triggering (stage 3 and 4) or multiple affected digits, the success of steroid injection is significantly lower at 1 month. For the latter patients, surgery may be a more reasonable initial treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Integrated Plastic Surgery Residency Applicant Trends and Comparison With Other Surgical Specialties.

BACKGROUND: There has been a relatively rapid increase in the number and size of "integrated" residency programs in plastic surgery (PS) over the past decade. The objective of this study is to evaluate trends of US senior applicants of PS compared with other surgical specialties from 2007 to 2016. METHODS: Data were obtained from "NRMP: Main Residency Match" and from "NRMP: Charting Outcomes in the Match." Frequencies, percentages, and proportions were calculated for categorical variables. Odds ratios with 95% confidence interval were calculated to evaluate the relationship of Alpha Omega Alpha membership and match success. RESULTS: The overall National Resident Matching Program match rate ranged from 93.1% to 95.1%, but rates were lower for surgical specialties, ranging from 74.7% to 86.6% in 2016. From 2008 to 2016, PS had a relatively high growth rate in the number of positions (65.2%) from 2008 to 2016. Matched PS and Otolaryngology applicants routinely had the highest mean United States Medical Licensing Examination Step 1 and Step 2 Clinical Knowledge scores. Alpha Omega Alpha membership has a significant impact on successfully matching into a surgical specialty (P < 0.1). Matched applicants of surgical subspecialties (PS, Otolaryngology, orthopedics, and neurosurgery) had similar mean number of research, work, and volunteer experiences. However, PS and neurosurgery matched applicants had notably higher mean research productivity. CONCLUSIONS: The rapid increase in the number of positions in PS residency training has not resulted in a decrease in caliber of matched applicants, even though match rates have dramatically increased. Currently, PS continues to attract and successfully match highly qualified applicants, but other surgical specialties have increasingly similar board scores and mean number of extracurricular experiences.

Learner Perspectives of a Surgical Educators Faculty Development Program Regarding Value and Effectiveness: A Qualitative Study.

BACKGROUND: The BaylorScott & White Health Division of Plastic Surgery began a faculty development program designed to train clinicians to be better educators. The program consisted of presession reading, 11 small group didactic sessions, and individually chosen educational projects. Cross-discipline collaboration was pursued by enrolling faculty and students from diverse departments. Department chair permission was required for participation. The purpose of this qualitative study was to explore learner perspectives of the Surgical Educators Program. METHODS: Fourteen physicians completed the Surgical Educators Program. Focus groups were held with the learners who completed the 2011 and 2012 programs 6 months after completion. The groups were moderated by an educational faculty member who was not involved in any aspect of the course. Questions were designed to elicit the components of the course curriculum of significance to the learners. Narrative data were digitally recorded and transcribed verbatim, and the investigators performed independent content analyses to identify themes. The data were thematically coded and summarized using calculation of frequencies. RESULTS: Thirteen learners participated in the focus groups. Three main themes were identified. First, the program increased the participants' knowledge and practice of medical education. Second, the structure of the program was a key contributor to the outcomes. Third, the program produced a community of practice. CONCLUSIONS: This study suggests that a faculty development program comprising a diverse group of physicians consisting of readings, guided small group sessions, and a mandatory project can train plastic surgical faculty to become better surgical educators within the constraints of a busy clinical practice.

The Perfect Preceptor.

Every plastic surgeon can become a better teacher. One of the keys to improvement is to have a thoughtfully considered plan of what to teach and how to teach it. This article describes what any surgeon can do before, during, and after a rotation to create an excellent learning environment for a medical student, resident, or fellow. Before the rotation, the preceptor should collaborate with the program director to develop the goals and objectives. The defined content is then distributed by week so that each objective is consciously addressed. During the rotation, the resident and preceptor identify the critical clinical and surgical experiences germane to the week's topic and focus on those patients. After the rotation, giving and getting meaningful feedback is much easier as the assessment scope and tool is derived from the curriculum that the preceptor helped develop.

Prevalence of brachial plexus injuries in patients with scapular fractures: A National Trauma Data Bank review.

BACKGROUND: Studies investigating the prevalence of brachial plexus injuries associated with scapular fractures are sparse, and are frequently limited by small sample sizes and often restricted to single-centre experience. OBJECTIVE: To determine the prevalence of brachial plexus injuries associated with scapular fractures; to determine how the prevalence varies with the region of the scapula injured; and to assess which specific nerves of the brachial plexus were involved. METHODS: The present study was a retrospective review of data from the National Trauma Data Bank over a five-year period (2007 to 2011). RESULTS: Of 68,118 patients with scapular fractures, brachial plexus injury was present in 1173 (1.72%). In patients with multiple scapular fractures, the prevalence of brachial plexus injury was 3.12%, and ranged from 1.52% to 2.22% in patients with single scapular fractures depending on the specific anatomical location of the fracture. Of the 426 injuries with detailed information on nerve injury, 208 (49%) involved the radial nerve, 113 (26.5%) the ulnar nerve, 65 (15%) the median nerve, 36 (8.5%) the axillary nerve and four (1%) the musculocutaneous nerve. CONCLUSION: The prevalence of brachial plexus injuries in patients with scapular fractures was 1.72%. The prevalence was similar across anatomical regions for single scapular fracture and was higher with multiple fractures. The largest percentage of nerve injuries were to the radial nerve.

HISTORIQUE: Il existe peu d'études sur la prévalence de lésions du plexus brachial liées aux fractures scapulaires. Celles qui existent sont souvent limitées par le petit échantillon et sont restreintes à l'expérience d'un seul centre. OBJECTIF: Déterminer la prévalence de lésions du plexus brachial associées à des fractures scapulaires, établir la variation de la prévalence selon la région de l'omoplate qui est touchée et évaluer les nerfs du plexus brachial qui sont atteints. MÉTHODOLOGIE: La présente analyse rétrospective évaluait les données de la National Trauma Data Bank sur une période de cinq ans (2007 à 2011). RÉSULTATS: Chez les 68 118 patients ayant des fractures scapulaires, 1 173 (1,72 %) avaient une lésion du plexus brachial. Chez les patients ayant des fractures scapulaires multiples, la prévalence de lésions du plexus brachial s'élevait à 3,12 %, et elle variait entre 1,52 % et 2,22 % chez ceux qui en avaient une seule, selon la région anatomique où elle était située. De l'information détaillée était fournie sur la lésion nerveuse de 426 blessures : 208 (49 %) touchaient le nerf radial, 113 (26,5 %), le nerf cubital, 65 (15 %), le nerf médian, 36 (8,5 %), le nerf axillaire, et quatre (1 %), le nerf musculocutané. CONCLUSION: La prévalence de lésions du plexus brachial s'élevait à 1,72 % chez les patients ayant des fractures scapulaires. Cette prévalence était similaire entre les régions anatomiques lorsqu'il s'agissait d'une fracture scapulaire simple, et plus élevée lorsque les fractures étaient multiples. Les lésions nerveuses touchaient surtout le nerf radial.
