The Safety of Fat Grafting: An Institutional Retrospective Review

BACKGROUND

Autologous fat grafting is a popular technique for volume replacement in the breast and face. The efficacy, safety, and complication rate of this technique at the division of plastic surgery at the University of Alabama at Birmingham will be described in this review.

METHODS

An institutional review board-approved retrospective review of patients undergoing fat grafting procedures from January 2015 to July 2018 was performed. Records were reviewed for fat graft recipient site, donor site, amount grafted, and complications. Continuous variables were compared using either a t test or one-way analysis of variance test. Categorical data were compared using χ2 test. A P value of 0.05 or less was considered statistically significant for all comparisons.

RESULTS

A total of 396 patients who underwent fat grafting procedures of the face and body from January 2015 through July 2018 met inclusion criteria. Average amount of fat grafted for all grafts was 124.4 +/- 6.74 grams. Two hundred fifty of the grafts (62.7%) involved the bilateral breasts with an average of 140.6 +/- 93.97 g used, 70 per side. Of the 396 patients, 110 (27.8%) experienced complications. Forty three of the complications (10.9%) were considered to be major, which included hematomas/seromas, fat necrosis, dermatitis/cellulitis, and infection. No statistical differences were seen among recipient site complication rate. Types of minor complications were statistically significant per recipient sites with bilateral breasts more likely to experience asymmetry than the other recipient sites (20% for bilateral breasts vs 16% overall, P < 0.05). Fifty nine of the 110 patients (53.6%) had the complications reported to be resolved.

CONCLUSIONS

Fat grafting is a reliable method for volumization of the breasts and face. Minor complications were not infrequent in this case series; however, no life-threatening complications were observed. Continued work needs to be done to use fat grafting beyond traditional measures.

Comprehensiveness of Online Information in Gender-Affirming Surgery: Current Trends and Future Directions in Academic Plastic Surgery

BACKGROUND

Despite high rates of online misinformation, transgender and gender diverse (TGD) patients frequently utilize online resources to identify suitable providers of gender-affirming surgical care.

AIM

The objective of this study was to analyze the webpages of United States academic plastic surgery programs for the types of gender-affirming surgery (GAS) procedures offered and to determine how this correlates with the presence of an institutional transgender health program and geographic region in order to identify potential gaps for improvement.

METHODS

Online institutional webpages of 82 accredited academic plastic surgery programs were analyzed for the presence of the following: GAS services, specification of type of GAS by facial, chest, body and genital surgery, and presence of a concomitant institutional transgender health program. This data was analyzed for correlations with geographic region and assessed for any significant associations.

OUTCOMES

Frequencies of GAS services, specification of the type of GAS by facial, chest, body and genital surgery, presence of a concomitant institutional transgender health program, and statistical correlations between these items are the primary outcomes.

RESULTS

Overall, 43 of 82 (52%) academic institutions offered GAS. Whether an institution offered GAS varied significantly with the presence of an institutional transgender health program (P < .001) but not with geographic region (P = .329). Whether institutions that offer GAS specified which anatomic category of GAS procedures were offered varied significantly with the presence of an institutional transgender health program (P < .001) but not with geographic region (P = .235).

CLINICAL IMPLICATIONS

This identifies gaps for improved transparency in the practice of communication around GAS for both physicians and academic medical institutions.

STRENGTHS & LIMITATIONS

This is the first study analyzing the quality, content, and accessibility of online information pertaining to GAS in academic institutions. The primary limitation of this study is the nature and accuracy of online information, as current data may be outdated and not reflect actuality.

CONCLUSION

Based on our analysis of online information, many gaps currently exist in information pertaining to GAS in academic settings, and with a clear and expanding need, increased representation and online availability of information regarding all GAS procedure types, as well as coordination with comprehensive transgender healthcare programs, is ideal.

Evaluation of surgical oncology fellowship websites: Are we showing what applicants need to see?

Background

The Internet is a major resource for surgery fellowship applicants, especially during the COVID-19 pandemic. Online information for surgical oncology and breast oncology training programs can be found on the Society of Surgical Oncology's webpage and fellowship institution websites. The goal of this study was to analyze the comprehensiveness of complex general surgical oncology and breast oncology fellowship websites.

Materials and methods

A list of all accredited surgical oncology and breast oncology fellowships was recorded from the Society of Surgical Oncology website and stratified by region. Then, a Google search was performed on each fellowship program to determine each institution's webpage. Two of the authors then analyzed 2 web resources, institutional website and Society of Surgical Oncology webpage, for each fellowship program to determine if information valued by applicants was provided.

Results

Online information of 29 surgical oncology fellowships and 59 breast oncology fellowships was analyzed. Statistical differences were found among criteria in major information categories between Society of Surgical Oncology and institutional webpages for both fellowship types. Detailed criteria were more present on institutional rather than Society of Surgical Oncology webpages.

Conclusion

For applicants to surgical oncology fellowships, institutional webpages provided the most pertinent information and may be used as a primary resource to guide fellowship application. For applicants to breast oncology fellowships, Society of Surgical Oncology webpages may be used as a primary resource to guide fellowship application. Both Society of Surgical Oncology and institutional pages lacked pertinent information regarding interview dates, and these resources should be updated to reflect program highlights as well as pertinent information for applicants.

The Correlation between Altmetric Score and Traditional Bibliometrics in Orthopaedic Literature

BACKGROUND

Clinicians and medical researchers increasingly turn to nonformal online platforms to promote research. Altmetric Attention Score (AAS) is a quantitative measurement of online influence of research in real time. The objective of this study is to determine if AAS correlates with traditional bibliometrics in the orthopaedic literature.

MATERIALS AND METHODS

From the 15 orthopaedic journals with the highest impact factor, the 10 most cited articles from each journal were reviewed for 2014 -2017. For each article, AAS was collected using the Altmetric Bookmarklet application and citation count from SCOPUS. Journal impact factor was recorded using Journal Citation Reports. Statistical analysis included Pearson's and Spearman's correlation coefficients.

RESULTS

A total of 600 articles were analyzed. A significant positive correlation was found between citation count and AAS for 2014 (r = 0.3188, p < 0.0001), and no correlation for 2015 (r = 0.1504, P = 0.0653), 2016 (r = 0.0087, P = 0.9157), and 2017 (r = 0.0061, P = 0.9408). There was no significant correlation between impact factor and AAS in 2014 (r = 0.4312, P = 0.1085), 2015 (r = 0.3850, P = 0.1565), 2016 (r = 0.1460, P = 0.6035) and 2017 (r = 0.0451 P = 0.8732).

CONCLUSIONS

AAS and traditional bibliometrics are currently not strongly correlated in orthopaedic literature. Citations take years to accumulate and AAS represents immediate influence of an article. An amalgamation of traditional bibliometrics and AAS may prove useful in determining the short- and long-term impact and influence of publications in orthopaedics.

Examining the Relationship between Altmetric Score and Traditional Bibliometrics in the Ophthalmology Literature for 2013 and 2016 Cohorts

Background In this study, we reviewed a select sample of ophthalmology literature to determine if there was a correlation between Altimetric and traditional citation-based and impact factor metrics. We hypothesized that Altmetric score would more closely correlate with impact factor and citations in 2016.

Methods Journal Citation Reports for the year 2013 was used to find the 15 highest impact factor ophthalmology journals in 2013. Then Elsevier's Scopus was used to identify the 10 most cited articles from each journal for the years 2013 and 2016. Metrics for all identified articles were collected using the Altmetric Bookmarklet, and date of Twitter account creation was noted for journals with such an account. Altmetric scores, impact factor, and citation counts were tabulated for each article. Pearson's correlation coefficient (r) determined correlation of independent variables (number of citations or impact factor) with dependent variable (Altmetric score). For our Twitter analysis, account age was the independent variable and calculated correlation coefficients (r) were the dependent variable. Proportion of variance was determined with a coefficient of determination (R 2).

Results This study included 300 articles, evenly split between 2013 and 2016. Within the 2013 cohort, three journals had significant positive correlations between citation count and Altmetric score. For the 2016 cohort, both Altmetric score and citation count (r = 0.583, p < 0.001) and Altmetric score and impact factor (r = 0.183, p = 0.025) revealed significant positive correlations. In 2016, two journals were found to have significant correlations between Altmetric score and citation number. Neither year revealed a significant correlation between the age of a journal's Twitter profile and the relationship between Altmetric score and citation count. In each year, Twitter accounted for the highest number of mentions.

Conclusion The findings suggest that correlation between Altmetric score and traditional quality metric scores may be increasing. Altmetric score was correlated with impact factor and number of citations in 2016 but not 2013. At this time, Altmetrics are best used as an adjunct that is complementary but not an alternative to traditional bibliometrics for assessing academic productivity and impact.

Two-Stage, Prepectoral Breast Reconstruction: Standardized Technique and Outcomes Analysis During First Stage to Reduce Complications and Ensure Reliability

GOALS

Prepectoral breast reconstruction is seeing a resurgence in popularity as advances in breast oncology and breast reconstruction continue to occur. This study seeks to describe a simple, reproducible method for prepectoral breast reconstruction and analyzes patient demographics and outcomes after the first stage of prepectoral breast reconstruction.

METHODS

After institutional review board approval was obtained, a retrospective chart review was performed to identify patients who underwent 2-stage prepectoral reconstruction by the senior author from January 2019 to February 2020. Patient demographics including body mass index, nicotine use, diabetes mellitus, neoadjuvant chemotherapy, and adjuvant radiation were analyzed. Type of mastectomy (nipple vs skin sparing), unilateral versus bilateral reconstruction, and use of intraoperative angiography were also assessed. Complications including excision of ischemic skin, delayed mastectomy flap ischemia, seroma, hematoma, axillary cellulitis, expander infection, and reconstructive failure were analyzed. χ2 Analysis was used to identify any association between the above demographics and infection, and P values were generated with a statistical significance being denoted by a P < 0.05.

RESULTS

One hundred five breast reconstructions were included in this study. A statistically significant association was found between nicotine use, diabetes mellitus, excision of ischemic skin, and expander infection. No significant association was found between other demographics and infection risk. Expander infection occurred in 2.86% of all reconstructions with an overall reconstructive failure rate of 2.86%.

CONCLUSIONS

This study demonstrates that our technique is reproducible and can be used for all types of mastectomies and incisions. Our data analysis demonstrates that this is a reliable method of breast reconstruction if performed correctly in the properly selected patient. Future studies will assess outcomes following the second stage of reconstruction.

Reconstructive Management of Gunshot Wounds to the Frontal Sinus: An Urban Trauma Center's Perspective

INTRODUCTION

In the last decade, we have seen a steady increase in the incidence of frontal sinus trauma due to gunshot wounds and a decrease in motor vehicle trauma. Penetrating gunshot wounds to the frontal sinus present a unique challenge to the reconstructive surgeon because they require careful consideration of the management principles of plastic surgery. Despite previous reviews on frontal sinus trauma, there are no studies examining the management techniques of frontal sinus fractures due specifically to gunshot wounds. In this study, we aim to retrospectively evaluate the use of a variety of tissue flaps in intervention and associated outcomes.

METHODS

A retrospective chart review was completed on all patients with gunshot wound(s) to the frontal sinus from January 2010 to January 2018 at a single institution. The patients were classified based on the fracture pattern (anterior vs posterior table vs both), degree of displacement, presence of nasofrontal outflow tract injury, and evidence of cerebrospinal fluid leak. Patients were then stratified according to the type of reconstruction performed (cranialization, obliteration and need for free flap) and evaluated for major and minor complications after reconstruction.

RESULTS

In this study, we present outcome data from 28 cases of frontal sinus trauma due to gunshot wounds. There was a statistically significant difference (P = 0.049) in the type reconstructive strategy employed with each type of flap, with pericranial flaps primarily used in cranialization, temporal grafts were more likely to be used in obliteration, and free flaps were more likely to be used in cranialization. The overall major complication rate was 52% (P = 0.248), with the most common acute major complication was cerebrospinal fluid leak (39%) and major chronic was abscess (23.5%).

CONCLUSIONS

This report explores the management of frontal sinus trauma and presents short-term outcomes of treatment for penetrating gunshot wounds at a tertiary referral center.

Mandibular Distraction Osteogenesis as a Primary Intervention in Infants With Pierre Robin Sequence

BACKGROUND

Pierre Robin sequence (PRS) is a triad of congenital facial abnormalities that can present as a syndrome (syndromic PRS [sPRS]) or an isolated entity (isolated PRS [iPRS]). Patients with PRS can develop airway and feeding problems that may result in failure to thrive. Mandibular distraction osteogenesis (MDO) is a method for improving the functional issues associated with breathing and feeding. There is a Paucity of literature evaluating the outcomes of MDO between sPRS and iPRS patients.

METHODS

An institutional review board-approved retrospective review of PRS patients managed by a single surgeon and treated with MDO between January 2015 and December 2019 at a tertiary referral hospital was performed. The patients were stratified into iPRS or sPRS based on gene testing. Airway outcome measures included avoidance of tracheostomy, relief of sleep apnea, and oxygen saturation improvement. Primary feeding measures included achievement of full oral feeds and growth/weight gain. Statistical analysis included t tests and χ2 tests where appropriate using SPSS.

RESULTS

Over the study period, of the 29 infants with PRS, 55% identified as iPRS and 45% as sPRS. There were no significant differences in the patient characteristics, apnea-hypoxia index (22.27 ± 12.27) and laryngeal view (3 ± 0.79) pre-MDO. After MDO, 83% of the subjects achieved a positive feeding outcome and 86% achieved a positive airway outcome with no statistical significance between sPRS and iPRS (P = 0.4369). There was a statistically significant change post-MDO in apnea-hypoxia index (5.24 ± 4.50, P = 0.02) and laryngeal view (1.59 ± 1.00, P = 0.01).

CONCLUSIONS

Our recent experience would lead us to believe that sPRS patients have greater morbidities and challenging clinical developments that, when properly evaluated, can be managed by MDO. There is a potential role for MDO in reducing the need for traditional surgical interventions for respiratory and feeding problems in both iPRS and sPRS patients.

Adipose Grafting for Volume and Scar Release

ABSTRACT

Adipose fat grafting (AFG) is a popular technique used to add volume in the face, breasts, and other tissue deficient areas of the body. In terms of scar release, not only has fat provided additional soft tissue coverage but also the relief of pain in scars in those patients suffering from disease processes, such as complex regional pain syndrome with steroid-induced atrophy, burn scars, morphea, and lupus. The purpose of this article is to demonstrate the senior author's technique and outcomes of using AFG in the face and body for treating volume deficiency, atrophic scarring, and deformities.A retrospective chart review of 127 AFG procedures of the face and body from September 2006 to September 2019 was performed. Of these, 14 patients had scar releases performed with fat grafting of areas of scar contracture. Fat was harvested from the abdomen, thighs, and flanks using Toomey syringes or an enclosed power-assisted system with 3.7- or 3.0-mm cannulas. Grafting in small areas, such as the face, was performed with the 0.9-mm blunt cannula.The majority of AFG was completed in the face (45%), followed by breasts (22%), and scar contracture (16%). The mean volume of fat grafted in procedures involving the breasts, buttocks, and face was 102, 182, and 21 mL, respectively. For scar contracture, the mean volume was 38 mL and for deformations, 27 mL. Sixteen percent of the cohort required at least 1 additional AFG procedure to achieve satisfactory results. There were no major complications, such as skin loss, vascular injury, embolization, or blindness. Minor complications, such as erythema, edema, and hematoma at the fat harvest or graft site, did occur and were managed with local measures.Autologous fat grafting has consistently resulted in volume correction. In addition, in patients with autoimmune disorders, burn scars, and retracted scars, not only has there been volume correction but also decreased pain in the area of treatment. In our series of patients, we described our technique of AFG for the face, body, and scar contracture. Our results demonstrate that AFG remains an inexpensive, safe, and effective treatment option to achieve volume.

The Content of US Plastic Surgery Private Practices' Websites

INTRODUCTION

Connecting patients with healthcare providers continues to grow as the digital era evolves. A successful website has the power to influence patients on choosing a practice and provider. The objectives of this study were to characterize information provided on private practice websites of plastics surgeons in the United States and to assess the relationship among the websites based on the number of years that the physicians have been in practice.

METHODS

Newly board-certified plastic surgeons by the American Board of Plastic Surgery in 2005, 2010, and 2015 were identified. A Google search was conducted on all participants, and only those in private practice were included in this study. Each webpage was quantitatively and qualitatively assessed for the presence or absence of 23 criteria that were categorized as practice, physician, patient, or procedure information. χ2 was used for statistical analysis using Microsoft Excel (PSPP 1.2.0). A P value of less than 0.05 was considered statistically significant.

RESULTS

Most plastic surgeons in each cohort were currently in private practice. A total of 532 plastic surgery private practice websites were analyzed. The data points found on 100% of the websites were directions to the facility and the contact for any billing questions. Most websites provided information on the practice and its surgeons. The most common web-based data points included online consultations and links to their social media. Information on expenses incurred by patients, such as cancellation policies and consultation fees, was least commonly listed.

CONCLUSIONS

Our study shows that the number of years in practice is not associated with comprehensiveness of their website's content. This study provides insight into the content of plastic surgery private practices' websites in the United States in relation to the practice, the physician, the patient, and the procedures. This information may be useful for expanding and optimizing their websites. This has the potential to increase patient satisfaction and visibility of the practice. The success of these businesses is vital as the private sector in plastic surgery continues to grow.

Ranking United States Plastic Surgery Residency Programs Based on Academic Achievement of Faculty Members

INTRODUCTION

The Doximity Residency Navigator is currently the only resource that ranks plastic surgery residency programs. Given the paucity of objective program rankings, in this study, we devised a new algorithm to rank plastic surgery programs based on academic achievement of faculty members.

METHODS

The Fellowship and Residency Electronic Interactive Database was used to obtain the following information on plastic surgery programs: the amount of 2017 National Institute of Health and Veterans Administration funding, lifetime and 5-year faculty h-indices, and the number of faculty on editorial boards of journals. Based on all of this information, an overall ranking of the top 25 plastic surgery programs was created.

RESULTS

The top program for annual National Institutes of Health and Veteran Affairs funding was the University of Southern California (integrated and independent). The top programs for faculty lifetime h-index were the University of Michigan (integrated) and New York University (independent). The top program for faculty 5-year h-index was the University of Pennsylvania (integrated and independent). The top program for the number of faculty members who are on the editorial boards of major journals was Harvard University (integrated and independent). The top program overall was Harvard University (integrated and independent).

CONCLUSION

We ranked plastic surgery residency programs based on objective data related to faculty academic achievement. Academic achievement rankings are just one of numerous other factors that medical students should synthesize when making informed decisions when applying to residency.

"Finding a General Surgeon: Self-Referral in the Digital Era"

BACKGROUND

As technology becomes more prominent in today's society, more patients turn to the Internet to self-refer for a range of surgical problems. Frequently, patients search a nearby hospital's website in order to find a physician. We hypothesized that the variability in hospital websites would make it difficult for patients to find a general surgeon for their care.

METHODS

We used the US News and World Report's Hospital Rankings 2018-2019 for this study. The "Find A Doctor" page within each hospital's website was searched for the following conditions: "hernia" and "gallbladder." Information on all suggested providers was collected, including medical specialty and gender. Descriptive statistics were used to analyze the data.

RESULTS

The median number of providers listed in each search was 18 (range: 1-204). For "hernia," general surgeons were not the majority of providers suggested at 12/16 institutions. For "gallbladder," general surgeons were not the majority of providers suggested at 14/16 institutions, and 3/16 institutions did not suggest any. All 16 institutions suggested a strong majority of male providers (range: 62-100% male; median: 83% male).

DISCUSSION

Considerable variation exists in the suggestion of medical providers for common general surgical problems among the top academic hospitals. Most notably, general surgeons are not listed as the primary providers for these conditions which they commonly manage. Health systems need to examine how their website suggest providers and ensure that patients can easily find the physician most suitable for their care.

Unleashing shear: Role of intercellular traction and cellular moments in collective cell migration

In the field of endothelial biology, the term "shear forces" is tied to the forces exerted by the flowing blood on the quiescent cells. But endothelial cells themselves also exert physical forces on their immediate and distant neighbors. Specific factors of such intrinsic mechanical signals most relevant to immediate neighbors include normal (Fn) and shear (Fs) components of intercellular tractions, and those factors most relevant to distant neighbors include contractile or dilatational (Mc) and shear (Ms) components of the moments of cytoskeletal forces. However, for cells within a monolayer, Fn, Fs, Mc, and Ms remain inaccessible to experimental evaluation. Here, we present an approach that enables quantitative assessment of these properties. Remarkably, across a collectively migrating sheet of pulmonary microvascular endothelial cells, Fs was of the same order of magnitude as Fn. Moreover, compared to the normal components (Fn, Mc) of the mechanical signals, the shear components (Fs, Ms) were more distinctive in the cells closer to the migration front. Individual cells had an innately collective tendency to migrate along the axis of maximum contractile moment - a collective migratory process we referred to as cellular plithotaxis. Notably, larger Fs and Ms were associated with stronger plithotaxis, but dilatational moment appeared to disengage plithotactic guidance. Overall, cellular plithotaxis was more strongly associated with the "shear forces" (Fs, Ms) than with the "normal forces" (Fn, Mc). Finally, the mechanical state of the cells with fast migration speed and those with highly circular shape were reminiscent of fluid-like and solid-like matter, respectively. The results repeatedly pointed to neighbors imposing shear forces on a cell as a highly significant event, and hence, the term "shear forces" must include not just the forces from flowing fluid but also the forces from the substrate and neighbors. Collectively, these advances set the stage for deeper understanding of mechanical signaling in cellular monolayers.
