Who Posts on Instagram? Using Natural Language Processing to Assess the Relationship Between Training Background and Content of 700,000 Posts.

Background: Instagram (Menlo Park, CA) is a major platform for the dissemination of plastic surgery (PS) information, but the training background of users is difficult to ascertain. Objectives: We sought to better characterize the source and content of PS-related posts on Instagram. Methods: Metadata from publicly available Instagram posts containing PS relevant hashtags was collected from December 2018 to August 2020 using Node.js (Node.js Foundation, San Francisco, CA). The data was characterized by account type, and post topics were analyzed using a custom dictionary of PS procedures applied with natural language processing. All data analyses were performed with R (The R Foundation, Vienna, Austria). Results: Board-certified plastic surgeons account for 38% of posts on Instagram, followed by organizations (31%), nonplastics-trained physicians (19%), facial plastics (5%), oculoplastics (1%), and nonphysician providers (5%). Oculoplastics had the highest engagement rate with their posts (3.7 ± 5.1), whereas plastic surgeons had the lowest (2.7 ± 4.2). Breast aesthetics was the predominant topic posted by plastic surgeons (42%, P < .001), and board certification phrases distinguished their posts from other account types (23%, P < .001). Nonphysician posts focused on nonsurgical aesthetics like Botox and fillers (80%). However, nonplastics-trained physicians and organizations significantly contributed to procedural subcategories in a similar distribution to plastic surgeons. Conclusions: Board-certified plastic surgeons are not the predominant source of PS content on Instagram. Furthermore, posts by plastic surgeons have the lowest rate of engagement out of all account types studied. Although declarations of board certification distinguish content from plastics disciplines, they are only used in 21% of posts.

Interplay of Oncoplastic Reconstruction and Adjuvant Radiation Therapy in Breast Cancer.

Purpose: Oncoplastic breast surgery (OBS) combines breast cancer tumor removal with the cosmetic benefits of plastic surgery at the time of breast-conserving surgery. Potential advantages of OBS include wider surgical margins around the tumor bed, while the natural shape and appearance of the breast are maintained more than standard lumpectomy procedures. However, limited information is available regarding the potential effect on adjuvant radiation treatment planning. Materials and Methods: Women with localized breast cancer undergoing lumpectomy with immediate OBS and adjuvant radiation therapy between 2014 and 2019 were reviewed. OBS was performed using volume displacement techniques and patients received whole-breast irradiation with 3-dimensional conformal radiation therapy. Results: Volume of additional ipsilateral breast tissue removed during OBS ranged from 21 to 2086 cm3 (median, 304 cm3), 29% of patients had >500 cm3 of tissue removed. Surgical margins were positive in 12.5% and were not affected by volume of breast tissue removed (445 vs 439 cm3). Patients with surgical clips more often received a lumpectomy bed boost (75.9% vs 50.0%), boost volumes were on average 157 cm3 with clips versus 205 cm3 without clips. Mean V105 was comparable in patients with >500 cm3 tissue removed and irradiated breast volume >1000 cm3, while higher absolute volumes were found in patients with >26 cm posterior separation (58.0 cm3 vs 102.7 cm3; P = .07). No meaningful difference was observed in Dmax or radiation coverage (95% of the volume receiving 95% of the prescription dose) for patients with >26 cm posterior separation, >500 cm3 of breast tissue removed, or irradiated breast volume >1000 cm3. Conclusions: Radiation dosimetry plans for patients undergoing oncoplastic surgery were acceptable and no significant radiation or surgical advantage was gained in patients with more tissue removed. Our study stresses the importance of clear communication between surgeons and radiation oncologists about sufficient marking of the lumpectomy cavity, using practices that minimize the need for re-excisions and minimize lumpectomy cavity disruption during rearrangement.

Autologous Breast Reconstruction Success Rates in Hypercoagulable Patients.

BACKGROUND: Hypercoagulable disorders may adversely affect microsurgical outcomes, including increased flap failure and complication rates. Outcomes specific to autologous breast reconstruction are not well described. METHODS: A retrospective review was performed of autologous breast reconstructions between 2009 and 2020. Patients with either a thrombophilic disorder (TD) diagnosis or a previous thrombotic event (TE) were identified. The analysis compared perioperative complications and flap success rates. RESULTS: In this series, 23 patients with a TD underwent 39 flaps, and 78 patients who had experienced a TE underwent 126 flaps, compared with 815 control patients, who underwent 1300 flaps. In logistic regression models, a TD diagnosis was an independent predictor of early total flap loss [OR, 8.42 (95% CI, 1.59 to 44.47); P = 0.01], late partial flap loss [OR, 3.9 (95% CI, 1.0 to 15.22); P = 0.05], and delayed healing [OR, 2.26 (95% CI, 1.02 to 5.04); P = 0.04]. TE history trended toward an association only with late partial flap loss ( P = 0.057). Flap salvage rates (25%) and flap success rates (92.3%) were statistically lower in patients with a TD but normal in patients who had experienced a TE. CONCLUSIONS: Microsurgical breast reconstruction is a reasonable option for patients with hypercoagulation disorders. No increased risk of flap complications was associated with a previous TE; however, TDs carried increased risk. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

An Updated Systematic Review and Meta-Analysis of Tissue Oximetry Versus Conventional Methods for Postoperative Monitoring of Autologous Breast Reconstruction.

BACKGROUND: Tissue oximetry monitoring has shown superior outcomes to conventional monitoring methods for autologous breast reconstruction in retrospective studies with consecutive cohorts. A recent study used consecutive cohorts with tissue oximetry as the earlier cohort and found that tissue oximetry was nonsuperior. We hypothesize that improvement in microsurgical outcomes with institutional experience confounds the superiority of tissue oximetry demonstrated in prior studies. This study aimed to perform a systematic review and meta-analysis of the outcomes of tissue oximetry monitoring compared with conventional monitoring. METHODS: Relevant studies were found using PubMed, Embase, and Web of Science searches for keywords such as near-infrared spectroscopy or tissue oximetry and microsurgery. Studies included compared tissue oximetry and conventional monitoring in autologous breast reconstruction patients. Studies were excluded if they did not contain a comparison group. Random-effective models were used to analyze early returns to the operating room, the total number of partial or complete flap loss, and late fat necrosis. RESULTS: Six hundred sixty-nine studies were identified; 3 retrospective cohort studies met the inclusion criteria. A total of 1644 flaps were in the tissue oximetry cohort, and 1387 flaps were in the control cohort. One study contained tissue oximetry as the former cohort; 2 had tissue oximetry as the latter. Neither technique was superior for any measured outcomes. The estimated mean differences between tissue oximetry and conventional monitoring method were early returns, -0.06 (95% confidence interval [CI], -0.52 to 0.410; P = 0.82); partial flap loss, -0.04 (95% CI, -0.86 to 0.79; P = 0.93); complete flap loss, -1.29 (95% CI, -3.45 to 0.87; P = 0.24); and late fat necrosis -0.02 (95% CI, -0.42 to, 0.39; P = 0.94). CONCLUSIONS: In a systematic review and meta-analysis of mixed timeline retrospective cohort studies, tissue oximetry does not provide superior patient outcomes and shifts our current understanding of postoperative breast reconstruction monitoring. Prospective studies and randomized trials comparing monitoring methods need to be included in the existing literature.

Predicting Complications in Breast Reconstruction: Development and Prospective Validation of a Machine Learning Model.

IMPORTANCE: Necrosis of the nipple-areolar complex (NAC) is the Achilles heel of nipple-sparing mastectomy (NSM), and it can be difficult to assess which patients are at risk of this complication (Ann Surg Oncol 2014;21(1):100-106). OBJECTIVE: To develop and validate a model that accurately predicts NAC necrosis in a prospective cohort. DESIGN: Data were collected from a retrospectively reviewed cohort of patients who underwent NSM and immediate breast reconstruction between January 2015 and July 2019 at our institution, a high -volume, tertiary academic center. Preoperative clinical characteristics, operative variables, and postoperative complications were collected and linked to NAC outcomes. These results were utilized to train a random-forest classification model to predict necrosis. Our model was then validated in a prospective cohort of patients undergoing NSM with immediate breast reconstruction between June 2020 and June 2021. RESULTS: Model predictions of NAC necrosis in the prospective cohort achieved an accuracy of 97% (95% confidence interval [CI], 0.89-0.99; P = 0.009). This was consistent with the accuracy of predictions in the retrospective cohort (0.97; 95% CI, 0.95-0.99). A high degree of specificity (0.98; 95% CI, 0.90-1.0) and negative predictive value (0.98; 95% CI, 0.90-1.0) were also achieved prospectively. Implant weight was the most predictive of increased risk, with weights greater than 400 g most strongly associated with NAC ischemia. CONCLUSIONS AND RELEVANCE: Our machine learning model prospectively predicted cases of NAC necrosis with a high degree of accuracy. An important predictor was implant weight, a modifiable risk factor that could be adjusted to mitigate the risk of NAC necrosis and associated postoperative complications.

Defining the Incidence of the Impostor Phenomenon in Academic Plastic Surgery: A Multi-Institutional Survey Study.

BACKGROUND: Impostor phenomenon occurs when high-achieving individuals have persistent self-doubt despite objective measures of competence and success, and has been associated with professional burnout and attenuated career advancement in medical specialties. This study aimed to define the incidence and severity of the impostor phenomenon in academic plastic surgery. METHODS: A cross-sectional survey containing the Clance Impostor Phenomenon Scale (0-100; higher scores indicating greater severity of impostor phenomenon) was distributed to residents and faculty from 12 academic plastic surgery institutions across the United States. Generalized linear regression was used to assess demographic and academic predictors of impostor scores. RESULTS: From a total of 136 resident and faculty respondents (response rate, 37.5%), the mean impostor score was 64 (SD 14), indicating frequent impostor phenomenon characteristics. On univariate analysis, mean impostor scores varied by gender (Female: 67.3 vs. Male: 62.0; p=0.03) and academic position (Residents: 66.5 vs. Attendings: 61.6; p=0.03), but did not vary by race/ethnicity, post-graduate year of training among residents, or academic rank, years in practice, or fellowship training among faculty (all p>0.05). After multivariable adjustment, female gender was the only factor associated with higher impostor scores among plastic surgery residents and faculty (Estimate 2.3; 95% Confidence Interval 0.03-4.6; p=0.049). CONCLUSION: The prevalence of the impostor phenomenon may be high among residents and faculty in academic plastic surgery. Impostor characteristics appear to be tied more to intrinsic characteristics, including gender, rather than years in residency or practice. Further research is needed to understand the influence of impostor characteristics on career advancement in plastic surgery.

Autologous Breast Reconstruction after Massive Weight Loss: Understanding Risks in a Growing Population.

BACKGROUND: Massive weight loss (MWL) may have suboptimal effects on tissues used for autologous reconstruction. With the rising rates of obesity and bariatric surgery, more patients who have experienced MWL will be presenting for breast reconstruction. The authors hypothesize that autologous breast reconstruction in patients with a history of MWL will have more complications and require more revisions compared with reconstruction in patients without a history of MWL. METHODS: A retrospective review was performed on patients who underwent autologous breast reconstruction by five microsurgeons at an academic institution from 2009 through 2020. Patients with a history of bariatric surgery or greater than 50-pound weight loss were identified and compared with patients who had not experienced MWL. Analysis compared demographics, operative details, complications, revision rates, and BREAST-Q scores. RESULTS: Of 916 patients who underwent 1465 flaps, 39 patients with MWL (4.3%) underwent 68 flaps (4.6%), and 877 patients without MWL underwent 1397 flaps. MWL patients were more likely to require blood transfusions postoperatively ( P = 0.005); experienced more surgical-site infections ( P = 0.02), wound-healing complications of flap ( P = 0.007) and donor sites ( P = 0.03), and late partial flap losses ( P = 0.03); and required more revisional surgery for flap ( P = 0.009) and donor sites ( P = 0.01). BREAST-Q scores were not statistically different for satisfaction with breasts or surgeon but were lower in MWL patients for psychosocial ( P = 0.01) and sexual well-being ( P = 0.04). CONCLUSIONS: Reconstructive surgeons should expect increased postoperative complications when performing autologous breast reconstruction in patients who have experienced MWL. These patients should be counseled on the possibility of an increased risk of postoperative complications and need for revisional surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Comparing tissue oximetry to doppler monitoring in 1367 consecutive breast free flaps.

BACKGROUND: Retrospective studies evaluating tissue oximetry in a more recent cohort have shown superiority in flap outcomes. This study compares the use of tissue oximetry in a historical cohort to clinical observation and handheld doppler in a more recent cohort. We hypothesize that there is no benefit to using tissue oximetry. METHODS: A retrospective review was performed on patients who underwent abdominal-based autologous breast reconstruction by five microsurgeons at an academic institution from 2009 to 2020. Method of postoperative flap monitoring was determined then operative details and complications were analyzed. RESULTS: 1367 flaps were reviewed; 740 flaps in 460 patients were monitored with clinical observation and tissue oximetry, and 627 flaps in 391 patients were monitored with clinical observation and handheld doppler. There were no statistical differences in ischemic (p = .59) or congestive complications (p = .41), flap salvage rates when exploring for venous or arterial compromise (p = .52), or early flap loss (p = .56). Although not significant, acute flap-related return to the operating room was lower in the doppler group (4.6%) compared to the oximetry group (6.1%; p = .22). Flaps monitored with tissue oximetry had a statistical increase in length of stay (4.8 ± 1.4 days vs. 3.8 ± 1.6 days; p ≤ .001). The rates of late partial flap loss and fat necrosis were significantly higher in the oximetry group (2.6%, 19/740 vs. 0.3%, 2/740; p = .04) and (18.2%, 135/740 vs. 13.6%, 85/627; p = .02), respectively. CONCLUSIONS: There is no statistical benefit to the use of tissue oximetry compared to handheld doppler in flap monitoring with regards to flap outcomes.

Characterizing Outcomes of Medial and Lateral Perforators in Deep Inferior Epigastric Perforator Flaps.

BACKGROUND: Perforators are typically found in rows in the deep inferior epigastric perforator (DIEP) flap. As methods to assess flap perfusion continue to improve, surgeons may be more likely to select perforators traditionally avoided. The purpose of this article is to describe clinical outcomes based on row and number of perforators to reevaluate flap and abdominal donor site morbidity. METHODS: A retrospective analysis was performed on patients who underwent breast reconstruction with DIEP flaps by four microsurgeons from 2013 to 2020. The row and number of perforators were determined from operative reports. Chi-square and t-test or nonparametric Fisher's exact test and Wilcoxon two-sample test were used for discrete and continuous variable, respectively, as applicable. Logistic regression was used for multivariable analyses. RESULTS: Of 628 flaps, 305 were medial row (58.7%), 159 were lateral row (30.6%), and 55 had both rows (10.6%). Partial flap loss was higher in both rows (p = 0.003). Fat necrosis was higher with medial (p = 0.03) and both rows (p = 0.01) when compared with lateral using multivariable analysis. Hernia or bulge was higher in lateral row flaps (lateral: 8/157, 5.1%; medial, 5/299, 1.7%; both, 0/55; p = 0.05); however, mesh was more commonly used in both row flaps (p = 0.05). There was no difference in fat necrosis or abdominal morbidity between single and multiple perforators. CONCLUSION: There was no difference in fat necrosis based on the number or row of perforators. The lateral row provides adequate perfusion but may be associated with an elevated risk of hernia or bulge. Patients may benefit from mesh, especially when both rows are dissected.

A Paradigm Shift: Outcomes of Early Autologous Breast Reconstruction after Radiation Therapy.

BACKGROUND: Radiation creates significant challenges for breast reconstruction. There is no consensus regarding optimal timing for autologous reconstruction following radiation. This study explores clearly defined, shorter time intervals between completion of radiation and reconstruction than previously reported. METHODS: A retrospective review was performed on patients who underwent autologous reconstruction by five microsurgeons at an academic institution from 2009 to 2020. Cohorts were selected by time elapsed between radiation and autologous reconstruction including <3 months, 3 to 6 months, 6 to 9 months, 9 to 12 months, 12 to 24 months, and >24 months. Analysis compared baseline characteristics, operative details, complications, revision rates, and BREAST-Q scores. Analysis of variance was used for continuous variables and chi-square for discrete variables. RESULTS: In total, 462 radiated patients underwent 717 flaps. There were 69 patients at <3 months (14.9%), 97 at 3 to 6 months (21%), 64 at 6 to 9 months (13.9%), 36 at 9 to 12 months (7.8%), 73 at 12 to 24 months (15.8%), and 123 at >24 months (26.6%). Age, time from mastectomy, and failure of primary reconstruction were higher at >24 months (p < 0.001). There was no difference between cohorts in intraoperative complications in radiated or nonradiated breasts. There was no difference in acute and late postoperative complications between cohorts. Wound-healing complications in radiated sides were lowest at <3 months and 3 to 6 months (5/69 [7.3%] and 11/97 [11.3%], respectively) compared with other groups (18.8-22.2%) but did not reach significance (p = 0.11). More fat graft revisions occurred at <3 months (p = 0.003). CONCLUSION: Reconstruction can be safely performed within 3 months after radiation without increases in intraoperative, acute, or late reconstructive complications.

Closed-Incision Negative Pressure Therapy Prevents Major Abdominal Donor-Site Complications in Autologous Breast Reconstruction.

BACKGROUND: Outcomes in autologous breast reconstruction continue to improve with refinements in microsurgical techniques; however, donor-site morbidity remains a concern. Closed-incision negative pressure therapy (ciNPT) has been shown to reduce wound complications. Limited evaluation in abdominal donor sites has shown promising results. We hypothesize that ciNPT will reduce abdominal donor-site complications. METHODS: A retrospective chart review was performed of patients who underwent abdominally based autologous free tissue transfer for breast reconstruction by 4 microsurgeons at an academic institution from 2015 to 2020. The application of a commercial ciNPT for donor-site management was at the discretion of the operating surgeon. Demographics, operative details, and management of donor-site complications were analyzed. RESULTS: Four hundred thirty-three patients underwent autologous breast reconstruction; 212 abdominal donor sites were managed with ciNPT and 219 with standard dressings. Demographics were statistically similar between groups. Abdominal wound healing complications were noted in 30.2% of ciNPT patients (64/212) and 22.8% of control patients (50/219, P = 0.08); however, overall wound complications were attributed to obesity on multivariable analysis. Closed-incision negative pressure therapy significantly decreased complications requiring reoperation (ciNPT 6.2%, 4/64; control 26.5%, 13/51; P = 0.004). There were no significant differences in surgical site infection rates (P = 0.73) and rates of abdominal scar revisions (ciNPT 11.8%, 25/212; control 9.1%, 20/219; P = 0.37). CONCLUSIONS: Use of ciNPT in abdominal donor-site management significantly decreases the incidence of delayed wound healing requiring surgical intervention, with one major wound healing complication prevented for every 6 donor sites managed with ciNPT.

Evaluating the Importance of Sub-Internships on the 2022 Integrated Plastic Surgery Match During Continued COVID-19 Regulations.

OBJECTIVE: Following the 2021 integrated plastic surgery match, we found a significant increase in home match rates and decrease in match rate for students without a home plastic surgery program with the elimination of visiting sub-internships and the initiation of virtual interviewing. With the return of visiting sub-internships in the 2022 match cycle, we hypothesize that these rates will approach values more consistent with historical controls. DESIGN: Program match data was obtained from posts to residency program Instagram pages and posts associated with the hashtag #PRSMatch2022. Data on visiting sub-internship matches was obtained from a publicly available Google Sheet with applicant contributors. The Chi square test was used to assess for differences. SETTING: Medical schools and plastic surgery programs were categorized into west, midwest, south, and northeast regions. PARTICIPANTS: Matched applicants to integrated plastic surgery residency programs. RESULTS: In total, 192 of 194 (99%) of applicants matched to integrated plastic surgery residency positions were identified. The match rate for applicants without an affiliated plastic surgery program (31.3%) increased from 2021 (p = 0.03) and returned to a level consistent with historical controls (p = 0.38). Similarly, the home program match rate (15.1%) and match rate for applicants from Top 40 medical schools (34.2%) decreased from 2021, returning to pre-pandemic levels (p = 0.63, p = 0.12). Finally, regional match preferences remained generally consistent with historical controls, apart from a higher proportion of northeast applicants matching to programs in the northeast (72.5%, p = 0.04), and a lower proportion of west applicants matching to programs in the west (26.3%, p = 0.002). CONCLUSIONS: The 2022 integrated plastic surgery match cycle saw a reversal of many of the changes to match rates seen in the 2021 cycle. These changes may be due to the reintroduction of visiting sub-internships following updates in COVID-19 policies.

Effect of COVID-19 Restrictions on 2021 Integrated Plastic Surgery Match Outcomes.

OBJECTIVE: Due to the Coronavirus Disease 2019 Pandemic (COVID-19), guidelines regarding both elimination of visiting subinternships and substitution of virtual interviews for the 2021 match were adopted. We hypothesize that these changes will result in an increase in home institution match rates compared to previous years. DESIGN: Program match data was obtained using information posted to residency program Instagram pages and the hashtag #PRSMatch2021. Chi square was used to assess differences between groups. SETTING: Medical school regions were categorized as West, Midwest, South, and Northeast and compared to match program region. PARTICIPANTS: Matched candidates to integrated plastic surgery residencies RESULTS: A total of 181/187 (96.8%) integrated plastic surgery matched candidates were identified. Compared to historical controls, there was a statistically significant increase in the home match rate (24.3%, p = 0.004) and statistically significant decrease in match rate for students without a home plastic surgery program (21.0%, p = 0.004). Similar to prior years, applicants were more likely to match in their own region for all regions (p < 0.001); however, there was a statistical increase in students staying in the South region for residency compared to previous years (p = 0.007). CONCLUSIONS: The 2021 match cycle resulted in an increase in home program match rates, while decreasing match rates among students without a home plastic surgery program. COVID-19 polices may have resulted in disadvantages to students from diverse institutional backgrounds. Influences of virtual subinternships and virtual interviews should be further evaluated.

A Systematic Review of Breast Reconstruction Options After Mastectomy in Massive Weight Loss Patients.

ABSTRACT: Given global trends in obesity and bariatric surgeries, there are an increasing number of women presenting for breast reconstruction after massive weight loss. There is a paucity of literature about breast reconstruction after mastectomy in patients with a history of massive weight loss. A literature review revealed 10 articles that discussed outcomes of different reconstruction techniques in patients with massive weight loss. Autologous reconstruction techniques and implant-based reconstruction techniques were assessed to evaluate the advantages, disadvantages, and indications of each approach specific to this unique patient population. This article provides a summary of expected outcomes, including complication profiles. Ultimately, consideration should be given for breast reconstruction of mastectomy defects in patients with a history of massive weight loss, as satisfactory results are demonstrated to be possible. Both autologous reconstruction and implant-based reconstruction present feasible options, although reconstruction in this patient population may be associated with increased need for revisions and a higher complication rate compared with patients without a history of massive weight loss. For this reason, it is imperative to appropriately manage preoperative expectations in patients with a history of massive weight loss.

Patient Satisfaction Increases with Nipple Reconstruction following Autologous Breast Reconstruction.

BACKGROUND: Nipple reconstruction has been linked to patient satisfaction; however, there is debate about the validity of these findings in autologous breast reconstruction patients. This study hypothesized that satisfaction would increase with nipple reconstruction following autologous breast reconstruction. METHODS: A comparison study was performed of autologous breast reconstruction patients. Patients completed a survey that included BREAST-Q and nipple satisfaction measures. A chart review identified reconstructive details. RESULTS: A total of 191 patients completed the survey (48 percent response rate), with an average age of 53.7 ± 10.0 years and follow-up time of 2.8 ± 1.5 years. Nipple-areola complex reconstruction was completed in 33 percent of patients (63 of 191). Nipple-areola complex tattoos were used most frequently [n = 37 (58 percent)], followed by local flaps [n = 10 (16 percent)], free nipple-areola complex grafts [n = 9 (14 percent)], and a combination of local flaps and tattoos [n = 7 (11 percent)]. In comparison to women who did not undergo nipple-areola complex reconstruction, women who underwent any type of nipple reconstruction had a statistically higher BREAST-Q score for Sexual Well-Being (60 ± 24 versus 50 ± 22; p = 0.01), Postoperative Satisfaction with Breasts (65 ± 11 versus 61 ± 12; p = 0.01), and Satisfaction with Surgeon (97 ± 6 versus 93 ± 16; p = 0.009). The average nipple satisfaction score was 74 ± 19. There were correlations between the nipple satisfaction score and BREAST-Q scores for Sexual Well-Being (r = 0.50; p < 0.001), Psychosocial Well-Being (r = 0.43; p < 0.001), and Postoperative Satisfaction with Breasts (r = 0.43; p < 0.001). CONCLUSION: Reconstruction of the nipple-areola complex is an important part of autologous breast reconstruction, resulting in increased sexual well-being and satisfaction with reconstructed breasts.

Global Trends in Plastic Surgery on Social Media: Analysis of 2 Million Posts.

BACKGROUND: Plastic surgeons and patients increasingly use social media. Despite evidence implicating its importance in plastic surgery, the large volume of data has made social media difficult to study. OBJECTIVES: The aim of this study was to provide a comprehensive assessment of plastic surgery social media content worldwide by utilizing techniques for analyzing large-scale data. METHODS: The hashtag "#PlasticSurgery" was used to search public Instagram posts. Metadata were collected from posts between December 2018 and August 2020. In addition to descriptive analysis, 2 instruments were created to characterize textual data: a multilingual dictionary of procedural hashtags and a rule-based text classification model to categorize the source of the post. RESULTS: Plastic surgery content yielded more than 2 million posts, 369 million likes, and 6 billion views globally over the 21-month study. The United States had the most posts of 182 countries studied (26.8%, 566,206). Various other regions had substantial presence including Istanbul, Turkey, which led all cities (4.8%, 102,208). The classification model achieved high accuracy (94.9%) and strong agreement with independent raters (κ = 0.88). Providers accounted for 40% of all posts (847,356) and included the categories physician (28%), plastic surgery (9%), advanced practice practitioners and nurses (1.6%), facial plastics (1.3%), and oculoplastics (0.2%). Content between plastic surgery and non-plastic surgery groups demonstrated high textual similarity, and only 1.4% of posts had a verified source. CONCLUSIONS: Plastic surgery content has immense global reach in social media. Textual similarity between groups coupled with the lack of an effective verification mechanism presents challenges in discerning the source and veracity of information.

A Comparative Analysis of Outcomes of Free Nipple Areolar Grafting in Autologous Breast Reconstruction.

BACKGROUND: Preserving the nipple areolar complex (NAC) increases satisfaction in breast reconstruction. This study aims to describe outcomes using free NAC grafts in microvascular breast reconstruction. METHODS: A case-control study evaluated prospective outcomes of microvascular breast reconstruction with free NAC grafts compared with matched controls with tattoo or local flap nipple reconstruction. Eligible patients for NAC grafting required correction of ptosis or nipple malposition. Postoperative photographs were rated for complications and aesthetics by the four study authors and two additional unbiased board-certified plastic surgeons. Satisfaction was measured with the BREAST-Q. RESULTS: Twenty patients who underwent 35 autologous breast reconstructions were analyzed. Nipple areolar reconstruction with grafts was completed with 13 NACs in 7 patients. The majority of free NAC grafts (11/13, 85%) were completed in immediate reconstruction, and 15% (2/13) were completed in delayed reconstruction. Partial graft hypopigmentation (mean 18.0%, standard deviation [SD] 7.5) was noted in all grafts. Less than half of grafts had areas of depigmentation (6/13, mean 6.1%, SD 7.5). Minor areas of partial loss occurred in 6/13 grafts (mean 2.9%, SD 4.6). Nipple projection was maintained in 54% of nipples (7/13). Depigmentation, hypopigmentation, graft loss, and projection were not statistically correlated with NAC aesthetic or overall aesthetic rating. However, NAC size (p = 0.003), position (p = 0.022), and symmetry (p = 0.028) were all correlated with aesthetic outcomes. Outcomes and satisfaction were similar to those seen with local flap reconstruction, although partial loss was less common in NAC grafts. CONCLUSION: Nipple reconstruction can successfully be performed in microvascular breast reconstruction using free grafts. Although partial graft hypopigmentation is common, smaller areas of graft loss or depigmentation are anticipated and do not affect aesthetic outcomes. The use of free NAC grafts may allow additional patients to use their own nipples as part of their microvascular reconstruction and avoid secondary NAC reconstruction procedures.

Do Nipple Necrosis Rates Differ in Prepectoral Versus Submuscular Implant-Based Reconstruction After Nipple-Sparing Mastectomy?

BACKGROUND: Nipple-sparing mastectomy (NSM) has become increasingly popular, given its oncologic safety and preserved nipple areolar complex (NAC) aesthetics. Reconstruction has recently shifted from traditional submuscular (SM) to prepectoral (PP) implant placement. It remains unclear how the plane of implant placement might affect NAC perfusion. Our goal was to assess postoperative outcomes following NSM with SM versus PP implant placement. METHODS: A retrospective single-institution review was performed of all patients undergoing NSM and immediate breast reconstruction in either the PP or SM plane from January 2015 to June 2019. Clinicopathologic details and 90-day complication rates were collected. SM and PP group complications were compared using Chi square analysis. RESULTS: A total of 288 breasts (160 patients) were included, including SM in 79 cases (44 patients) and PP in 209 cases (116 patients). Clinicopathologic features between groups were similar. Overall, the rate of NAC necrosis was 15.1%, with no differences between the SM and PP cohorts (p = 0.79). In cases of NAC necrosis, there was no difference between the SM and PP groups in return to the operating room for debridement (p = 1.0) or explant (p = 0.33). CONCLUSIONS: In our cohort, immediate implant-based reconstruction in the SM and PP planes following NSM was equally safe with respect to postoperative complications and NAC ischemia.
