Livestreaming Microsurgery Education: An Avenue to Expand Global Plastic Surgery.

Microsurgery is a complex subspecialty requiring fine manual dexterity and a thorough understanding of microsurgical techniques, requiring years of training to reach proficiency. On a global scale, trainees may not have access to a longitudinal microsurgery curriculum and instead attend brief courses to learn microsurgical techniques, limiting their ability to practice the nuances of microsurgery. There remains a gap in global microsurgical education for trainees to have consistent educational exposure. This article presents a novel and easy to use software-based microsurgical system for virtual microsurgical teaching. In doing so, this system provides a free-of-cost and highly accessible avenue to deliver consistent microsurgical education worldwide.

Social media analysis of pain outcomes following targeted muscle reinnervation.

AIM: Targeted muscle reinnervation (TMR) was developed to improve myoelectric prosthesis control for amputees; however, it has become an area of interest in pain modulation. Evidences indicate that this procedure alleviates chronic pain in amputees. The primary objective of this study was to use social media analysis to understand patients' post-operative pain, satisfaction, and recovery time after TMR. METHODS: Data were collected from one Facebook group via posts and comments referencing TMR. Posts published between January 1, 2020, and March 24, 2023 were analyzed. Data collected included pain prior to surgery, pain in immediate post-op period, and change in pain after surgery. RESULTS: Forty-three individuals commented on their TMR experience. Among them, 31 had favorable surgical outcomes, 7 felt that the surgery worsened their pain or there was no significant change in their pain levels, and 5 commented during the initial post-operative period. Twenty-four patients described their pain in the immediate post-operative period and all patients said that the post-operative pain was worse than chronic pain. Among the 28 authors who commented on overall reduction in chronic pain, 24 reported that TMR reduced their pain, whereas 4 reported no change or worsened pain. CONCLUSIONS: The number of patients (24) who reported improvement in chronic pain aligns with the results in current literature suggesting that TMR is a viable treatment option for pain management. With the current medical management of similar conditions, up to 80% of patients remain unsatisfied with pain management. This analysis supports the evidence that TMR is an effective treatment for patients experiencing post-amputation pain.

Perforator Dissection Porcine Abdominal Model: A Novel Simulator to Improve Microsurgical Training.

BACKGROUND: Perforator dissection and flap elevation are routinely performed for microsurgical reconstruction; however, there is a steep learning curve to mastering these technical skills. Though live porcine models have been utilized as microsurgical training models, significant drawbacks limit their use. We recently developed a latex-perfused, nonliving, porcine abdomen perforator dissection simulation and described its anatomic similarity to the human deep inferior epigastric artery flap. The purpose was to assess the change in resident confidence in performing key operative steps of flap elevation and perforator dissection and obtain feedback on model realism and utility. METHODS: Seventeen plastic and reconstructive surgery resident physicians (postgraduate years 1-6) at a single institution participated in a perforator dissection session utilizing the simulation model. Each resident completed pre- and postactivity surveys to assess interval change in confidence in operating. The postactivity survey also asked residents to answer questions regarding their perception of the model's anatomic and surgical realism and utility in microsurgical training. RESULTS: Following a practice session using the latex-perfused, nonliving porcine abdomen, resident confidence was significantly increased in performing all key operative steps and the procedure overall (p = 0.001). All residents (n = 17, 100%) believed the model would improve "trainees' ability to perform perforator dissection in the operating room." Perforator, fascial, and pedicle anatomy were reported to be "Very" similar to human anatomy, with a median Likert score (MLS) of 4. Additionally, six out of the eight surgical steps were noted to be "Very" realistic, with only "Flap Design" and "Fascial Closure" found to be "Moderately" realistic with an MLS of 3. CONCLUSION: The latex-infused porcine abdominal model is a novel, realistic simulation for microsurgical trainee perforator dissection practice. This model offers a suitable substitute for perforator dissection practice, as its implementation within a microsurgery training course improves resident comfort and confidence.

Latex-Infused Porcine Abdominal Model: A Novel Microsurgery Simulator for Deep Inferior Epigastric Perforator Dissection.

BACKGROUND: Perforator dissection and flap elevation are routinely performed for microsurgical reconstruction; however, there is a steep learning curve to mastering these technical skills. Though live porcine models have been utilized as a microsurgical training model, there are significant drawbacks that limit their use, including cost, limited ability for repetition, and obstacles associated with animal care. Here we describe the creation of a novel perforator dissection model using latex augmented non-living porcine abdominal walls. We provide anatomic measurements that demonstrate valuable similarities and differences to human anatomy to maximize microsurgical trainee practice. METHODS: Six latex-infused porcine abdomens were dissected based on the deep cranial epigastric artery (DCEA). Dissection was centered over the abdominal wall mid-segment between the second and fourth nipple line. Dissection steps included exposure of lateral and medial row perforators, incision of anterior rectus sheath with perforator dissection, and dissection of DCEA pedicle. DCEA pedicle and perforator measurements were compared with deep inferior epigastric artery (DIEA) data in the literature. RESULTS: An average of seven perforators were consistently identified within each flap. Assembly of the model was performed quickly and allowed for two training sessions per specimen. Porcine abdominal walls demonstrate similar DCEA pedicle (2.6 ± 0.21 mm) and perforator (1.0 ± 0.18 mm) size compared with a human's DIEA (2.7 ± 0.27 mm, 1.1 ± 0.85 mm). CONCLUSION: The latex-infused porcine abdominal model is a novel, realistic simulation for perforator dissection practice for microsurgical trainees. Impact on resident comfort and confidence within a microsurgical training course is forthcoming.

Management of common conditions of the musician: a narrative review for plastic surgeons.

Career-related injuries and disorders in professional musicians are prevalent across all their respective instruments and fields. They often endure long hours of intensive practice that demand high levels of precision, dexterity, and flexibility of their head, neck, hands, and upper extremities. Unlike the average patient, musicians are sensitive to even mild symptoms and deficits that can interfere with performance, which can potentially be career-threatening. Increasing attention to the care of musicians motivated performing arts medicine to tailor the practice to their individual and unique needs. Plastic surgeons are at the forefront of this practice; however, there are very limited reviews discussing plastic surgery management of the common injuries and disorders in musicians. This article reviews the most relevant literature of the past several decades regarding treatment modalities of the most common conditions endured by professional instrumentalists, with an emphasis on surgical considerations in the field of plastic surgery. A thorough literature search was performed for articles that encompass the interface between plastic surgery and musicians. We examined disorders of the head, ears, eyes, nose, throat, hands, and upper extremities including stress velopharyngeal incompetence, disruption of the embouchure, nerve entrapments, arthritis, traumatic injuries, focal dystonia, Linburg-Comstock syndrome, and overuse disorder. Overall, the goal of this review is to provide a summary of the existing and successful procedures performed to address prevalent musician conditions.

Surgeon or Bot? The Risks of Using Artificial Intelligence in Surgical Journal Publications.

Mini-Abstract ChatGPT is an artificial intelligence (AI) technology that has begun to transform academics through its ability to create human-like text. This has raised ethical concerns about its assistance in writing scientific literature. Our aim is to highlight the benefits and risks that this technology may pose to the surgical field.

A framework for understanding prosthetic embodiment for the plastic surgeon.

Plastic surgeons play a critical role in the management of amputations and are uniquely positioned to improve the lives and functional abilities of patients with limb loss. The embodiment of a prosthesis describes how effectively it replaces a missing limb and is an important aspect of patient care. Despite its importance, the current prosthetics literature lacks a formal definition of embodiment, and descriptions are often vague or incomplete. In this narrative review, we assess the current literature on prosthetic embodiment to explore the main mechanisms of embodiment and how each allows a prosthesis to interface with the human body. In doing so, we provide a comprehensive, holistic framework for understanding this concept.

To Decline or Accept: A Guide for Determining the Legitimacy of Academic Conference Invitations.

IMPORTANCE: After the rise of predatory journals characterized by false claims of legitimacy and a pay-to-publish model, similar "predatory conferences" have become increasingly common. The email inbox of an academic physician can be filled with daily announcements encouraging conference attendance, abstract submission, and often panel or keynote speaker invitations. It therefore becomes important for the plastic surgeon to be able to discern whether these invitations are from "predatory" conferences or legitimate career advancement opportunities, especially early in practice. OBJECTIVE: To aid the invited physician in determining the legitimacy of a conference, we aimed to characterize objective features of conferences for which email invitations have been received and use this information to build a decision-making guide. DESIGN: We analyzed all conference invitations received by the email of one academic plastic surgeon in a 4-month period. These conferences were organized into 3 groups based on affiliation with known professional societies. The following information was collected if available: affiliation with a professional society, type of invitation, conference location, conference format (in-person, virtual, or hybrid), conference title, conference fees, conference organizer, associated journals or publishers, abstract journal submission, grammar, headshots, time to abstract review, and acceptance. RESULTS: There were 56 unique conference invitations. These were categorized into 15 affiliated conferences, 28 unaffiliated conferences, and 17 conferences of undetermined affiliation. Unaffiliated conferences were more likely to solicit speaker invitations ( P < 0.001), claim to be "international" ( P = 0.001), send emails with grammatical errors ( P < 0.001), use unprofessional headshots on the conference Web site ( P < 0.001), and have reduced virtual conference fees ( P = 0.0032) as compared with conferences affiliated with known professional societies. When comparing the attendance and presenter fees of in-person venues, there was no significant difference between affiliated and unaffiliated conferences ( P = 0.973, P = 0.604). Affiliated conferences were more likely to take place in the United States ( P = 0.014). CONCLUSIONS AND RELEVANCE: We present a method to quickly assess the legitimacy of an academic meeting by way of a few important questions. Based on our findings, emails soliciting conference speakers, claims of international presence, grammatical errors, unprofessional headshots, and reduced virtual conference fees are all characteristics that should raise red flags.

Optimizing Actigraphic Estimation of Sleep Duration in Suspected Idiopathic Hypersomnia.

STUDY OBJECTIVES: To determine the optimal Actiwatch 2 setting configuration for the estimation of total sleep time (TST) in persons with suspected idiopathic hypersomnia. METHODS: Thirty-three patients with a diagnosis of idiopathic hypersomnia (28 female; mean age = 33.7 ± 10.5) underwent ad libitum polysomnography with concurrent use of the Actiwatch 2. Actiwatch 2 sleep-wake activity threshold (SWAT; Low, Medium, and High) and sleep immobility onset and offset (SIOO; 5, 10, 15, 20, 25, and 30 epoch) duration were modified during data processing. The resultant 18 unique setting combinations were subsequently evaluated using Bland-Altman and epoch comparison analyses to determine optimal settings relative to polysomnography. RESULTS: Low SWAT + 25 Epoch SIOO displayed the least divergence from polysomnography (mean difference 3.4 minutes). Higher SWAT and lower SIOO increased sensitivity and accuracy, but at the expense of reducing specificity and the ability to accurately estimate TST. CONCLUSIONS: These results demonstrate that actigraphic settings should be carefully considered when estimating sleep duration. The Low + 25 Epoch configuration is indicated as most optimal for estimating TST in persons with suspected idiopathic hypersomnia. COMMENTARY: A commentary on this article appears in this issue on page 539.

Ability of the Fitbit Alta HR to quantify and classify sleep in patients with suspected central disorders of hypersomnolence: A comparison against polysomnography.

Measuring sleep duration and early onset rapid eye movement sleep (REMS) is critical in the assessment of suspected central disorders of hypersomnolence (CDH). Current multi-sensor activity trackers that integrate accelerometry and heart rate are purported to accurately quantify sleep time and REMS; however, their utility in suspected CDH has not been established. This investigation aimed to determine the ability of a current, multi-sensor tracker, Fitbit Alta HR (FBA-HR), to quantify and classify sleep in patients with suspected CDH relative to polysomnography (PSG). Forty-nine patients (46 female; mean age, 30.3 ± 9.84 years) underwent ad libitum PSG with concurrent use of the FBA-HR. FBA-HR sleep variable quantification was assessed using Bland-Altman analysis. FBA-HR all sleep (AS), light sleep (LS; PSG N1 + N2), deep sleep (DS; PSG N3) and REMS classification was evaluated using epoch-by-epoch comparisons. FBA-HR-detected sleep-onset rapid eye movement periods (SOREMPs) were compared against PSG SOMREMPs. FBA-HR displayed significant overestimation of total sleep time (11.6 min), sleep efficiency (1.98%) and duration of deep sleep (18.2 min). FBA-HR sensitivity and specificity were as follows: AS, 0.96, 0.58; LS, 0.73, 0.72;DS, 0.67, 0.92; REMS, 0.74, 0.93. The device failed to detect any nocturnal SOREMPs. Device performance did not differ appreciably among diagnostic subgroups. These results suggest FBA-HR cannot replace EEG-based measurements of sleep and wake in the diagnostic assessment of suspected CDH, and that improvements in device performance are required prior to adoption in clinical or research settings.
