In hospital outcomes of autologous and implant-based breast reconstruction in patients with chronic obstructive pulmonary disease.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common comorbid condition that can be associated with postoperative mortality and morbidity. However, the outcome profile of patients with COPD after breast reconstruction has yet to be established. Therefore, this study aimed to assess the postoperative outcomes in patients with COPD who underwent autologous (ABR) and implant-based breast reconstruction (IBR). METHODS: National Inpatient Sample was used to identify patients who underwent ABR or IBR from Q4 2015 to 2020. Multivariable logistic regressions were used to compare inhospital outcomes between COPD and non-COPD patients while adjusting for demographics, primary payer status, hospital characteristics, and comorbidities. RESULTS: There were 1288 (9.92%) COPD and 11,696 non-COPD patients who underwent ABR. Meanwhile, 1742 (9.70%) COPD and 16,221 non-COPD patients underwent IBR. In both ABR and IBR, patients with COPD had higher rates of seroma (ABR, aOR = 1.863, 95% CI = 1.022-3.397, and p = 0.04; IBR, aOR = 1.524, 95% CI = 1.014-2.291, and p = 0.04), infection (ABR, aOR = 1.863, 95% CI = 1.022-3.397, and p = 0.04; IBR, aOR = 1.956, 95% CI = 1.205-3.176, and p = 0.01), and prolonged LOS (p < 0.01). Specifically, patients with COPD in ABR had higher risks of respiratory complications (aOR = 1.991, 95% CI = 1.291-3.071, and p < 0.01) and incurred higher total hospital charges (p < 0.01). Meanwhile, patients with COPD undergoing IBR had elevated risks of renal complications (aOR = 3.421, 95% CI = 2.108-5.55, and p < 0.01), deep wound complications (aOR = 3.191, 95% CI = 1.423-7.153, and p < 0.01), and a higher rate of transfers out (aOR = 1.815, 95% CI = 1.081-3.05, and p = 0.02). CONCLUSION: COPD is an independent risk factor associated with distinct adverse outcomes in ABR and IBR. These findings can be valuable for preoperative risk stratification, determining surgical candidacy, and planning postoperative management in patients with COPD.

In hospital outcomes of autologous and implant-based breast reconstruction in patients with diabetes mellitus: A population-based study of 2015-2020 national inpatient sample.

BACKGROUND: Breast reconstruction encompasses autologous (ABR) and implant-based breast reconstruction (IBR) each with its own sets of potential complications. Diabetes mellitus (DM) is associated with breast reconstruction complications, although most of the studies did not differentiate between the reconstruction procedures. This study conducted a population-based study examining impact of DM on inhospital outcomes in ABR and IBR. METHODS: Patients underwent ABR or IBR were identified in National Inpatient Sample from Q4 2015 to 2020. A 1:2 propensity score matching was used to address differences in demographics, hospital characteristics, primary payer status, comorbidities, and reconstruction staging between DM and non-DM patients. In hospital outcomes were assessed separately in ABR and IBR. RESULTS: There were 997 (7.68%) DM and 11,987 (92.32%) non-DM patients in ABR. Meanwhile, 1325 (7.38%) DM and 16,638 (92.62%) non-DM patients underwent IBR. DM cohorts in ABR and IBR were matched to 1930 and 2558 non-DM patients, respectively. After matching, DM patients in both ABR and IBR had higher risks of renal complications (ABR, 3.73% vs. 1.76%, p < 0.01; IBR, 1.83% vs. 0.78%, p = 0.01) and longer length of stay (ABR, p = 0.01; IBR, p = 0.04). In ABR, DM patients had higher respiratory complications (2.82% vs. 1.19%, p < 0.01), excessive scarring (2.72% vs. 1.55%, p = 0.03), and infection (2.42% vs. 1.14%, p = 0.01), while in IBR, DM patients had higher hemorrhage/hematoma (5.40% vs. 3.40%, p < 0.01) and transfer out (1.52% vs. 0.78%, p = 0.04). CONCLUSION: DM was associated with distinct sets of inhospital complications in ABR and IBR, which can be valuable for preoperative risk stratification and informing clinical decision-making for DM patients.

Simultaneous Free Flap Breast Reconstruction Combined With Contralateral Mastopexy or Breast Reduction: A Propensity-Matched National Surgical Quality Improvement Program Study on Postoperative Outcomes.

BACKGROUND: Simultaneous free flap breast reconstruction combined with contralateral mastopexy or breast reduction can increase patient satisfaction and minimize the need for a second procedure. Surgeon concerns of increases in operative time, postoperative complications, and final breast symmetry may decrease the likelihood of these procedures being done concurrently. This study analyzed postoperative outcomes of simultaneous contralateral mastopexy or breast reduction with free flap breast reconstruction. METHODS: By using the American College of Surgeons National Surgical Quality Improvement Program database (2010-2020), we analyzed 2 patient cohorts undergoing (A) free flap breast reconstruction only and (B) free flap breast reconstruction combined with contralateral mastopexy or breast reduction. The preoperative variables assessed included demographic data, comorbidities, and perioperative data. Using a neighbor matching algorithm, we performed a 1:1 propensity score matching of 602 free flap breast reconstruction patients and 621 with concurrent contralateral operation patients. Bivariate analysis for postoperative surgical and medical complications was performed for outcomes in the propensity-matched cohort. RESULTS: We identified 11,308 cases who underwent microsurgical free flap breast reconstruction from the American College of Surgeons National Surgical Quality Improvement Program database from the beginning of 2010 to the end of 2020. A total of 621 patients underwent a free flap breast reconstruction combined with contralateral mastopexy or breast reduction. After propensity score matching, there were no significant differences in patient characteristics, perioperative variables or postoperative medical complications between the 2 cohorts. CONCLUSIONS: Simultaneous free flap breast reconstruction combined with contralateral mastopexy or breast reduction can be performed safely and effectively without an increase in postoperative complication rates. This can improve surgeon competence in offering this combination of procedures as an option to breast cancer survivors, leading to better patient outcomes in terms of symmetrical and aesthetically pleasing results, reduced costs, and elimination of the need for a second operation.

Thirty-Day Complication Rates After Gender-Affirming Bottom Surgery: An Analysis of the NSQIP Database From 2010 to 2020.

PURPOSE: Gender-affirming bottom surgeries (GABS) play a central role in treating gender dysphoria to improve quality of life for transgender and nonbinary (TGNB) patients. However, there exists limited data on operative risks and outcomes for patient populations undergoing GABS. The goal of this study is to identify sociodemographic and clinical risk factors for determining 30-day postoperative complications in patients undergoing GABS. METHODS: The ACS-NSQIP database from 2010 to 2020 was used to identify patients undergoing gender affirmation surgery (GAS) using Current Procedural Terminology (CPT) codes included in transfeminine and transmasculine bottom surgery. IBS-SPSS software was used to perform a multivariate analysis to determine risk factors for increased 30-day postoperative complications including unplanned reoperation and readmission rates. RESULTS: A total of 1809 GABS were performed in the NSQIP database from 2010 to 2020. There was an upward trend in GABS procedures throughout the years, with 2017 having the most GABS (n = 629). Transmasculine patients with a BMI of 29 and over were at a greater risk for wound complications (P < 0.05). Diabetic transfeminine patients were also at a greater risk for wound complications (P < 0.05). CONCLUSIONS: This study identified that several sociodemographic and clinical risk factors, such as BMI and diabetes mellitus type 2, had increased postoperative complications for patients undergoing gender-affirming bottom surgeries. Wound care management and patient education are essential in GABS to prevent long-term complications. Physician awareness of risk factors and social determinants of health can help prevent and improve postoperative care education and patient compliance.

Clinical and Financial Implications of Positive Margins After Nonmelanoma Skin Cancer Resection: A Longitudinal Evaluation.

BACKGROUND: Management of positive margins after nonmelanoma skin cancer (NMSC) excision is debated in the literature. The purpose of this study is to determine the rate of residual tumor in reexcised NMSC specimens after previous excision with positive margins, to determine the rate of recurrence in patients who had positive margins but did not undergo reexcision, and to define the financial burden of negative reexcisions. METHODS: An Institutional Review Board-approved retrospective review was conducted on all patients with NMSC excision over a 15-year period. Patients who met inclusion criteria and underwent initial NMSC excision with negative frozen section margins, but had positive permanent section margins were divided into 2 groups: those who underwent reexcision for clearance of tumor (n = 161) or those who did not undergo further reexcision (n = 105). Variables collected include demographics, previous skin cancer, tumor location, cancer subtype, excision measurements, and time between first and second excisions. For those patients who did not undergo reexcision, charts were examined for recurrence. RESULTS: Two hundred sixty-six patients met inclusion criteria with mean follow-up of 60 months. Eighty-three (52%) of 161 patients with positive margins on initial excision had no evidence of residual cancer upon reexcision. Residual tumor on permanent section was confirmed in 48% of patients. Patients with a previous history of basal cell carcinoma were more likely to have a true-positive margin after reexcision (P = 0.02). Larger reexcisions were more likely to harbor residual cancer (5.9 cm2, P = 0.04). Patients with positive margins that did not undergo reexcision, only 7 of 105 patients (6.6%) had recurrence. No mortalities were reported from NMSC recurrence. US $247,672 was spent in reexcision for negative margins in 98 patients for an average cost of US $2984 per case. CONCLUSIONS: Forty-eight percent of NMSC patients with positive margins had residual tumor upon reexcision. There were 6.6% of the patients who did not undergo resection after positive margins developed recurrence of disease at 5 years. Patients requiring larger reexcisions or those with a prior history of BCC were more likely to have residual cancer upon reexcision. This study suggests that observation is an appropriate option of care for certain patients with residual NMSC on permanent pathology.

The Use of Glabrous Skins Grafts in the Treatment of Pediatric Palmar Hand Burns.

BACKGROUND: An often overlooked, yet useful, technique in the treatment of palmar hand burns is the use of glabrous skin grafting, particularly in dark-skinned individuals. Pediatric palmar burns are a particularly unique subset of burns. The typical split-thickness or full-thickness skin grafts leave a notably different skin texture and pigmentation. It is also known that the psychological aspects of a pediatric burn can be quite burdensome for a child as he or she progresses through childhood and adolescence. For a dark-skinned patient the placement a standard full-thickness skin graft in a nonpigmented palm provides for a constant reminder of a traumatic event. We report a case series of pediatric patients who were managed with glabrous skin grafting from the plantar aspect of the foot. METHODS: A retrospective review of palmar skin burns requiring grafting at a single pediatric burn center experience over a 2 and a half year time period was performed. Seventeen patients were identified. Our treatment algorithm for deep partial thickness burns first relies on a combination of operative and nonoperative measures to expedite the demarcation of the burn injury. If the burn is full thickness in nature or if a lack of progression of healing is identified within the first 14 days of injury, then skin grafting is recommended. Our technique for performing the graft is described. RESULTS: The average age at time of surgery was 2.05 years (6 months to 6.8 years). Fourteen of the 17 patients had darker skin types (Fitzpatrick Type III-VI) and identified themselves as either Hispanic or African American. The average size of the area requiring skin graft after debridement was 0.94% total body surface area (0.5%-2.0%). Of the patients that were not lost to follow-up, 1 patient required additional grafting after developing a finger contracture for splint noncompliance. Aesthetically, the wounds went on to heal with an excellent pigment match and an inconspicuous donor site. CONCLUSIONS: In the management of deep-partial or full-thickness palmar skin burns in the pediatric population that require grafting, the use of plantar glabrous skin grafts offers a reliable option for coverage. The aesthetic and functional results are improved over standard techniques.

Impact of adjuvant chemotherapy on abdominal wall hernias and bulges after muscle-sparing free TRAM flaps for breast reconstruction.

BACKGROUND: Free tissue transfer from an abdominal donor site has become a popular method for postmastectomy breast reconstruction. The detrimental effects of adjuvant chemotherapy on healing and the resulting clinical impact on patient outcome remains somewhat unclear for abdominal bulges and hernias resulting after free tissue transfer from the abdominal donor site. METHODS: An institutional review board-approved retrospective review of 155 free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps performed for breast reconstruction was undertaken to evaluate the effect of adjuvant chemotherapy on abdominal donor-site morbidity. The primary outcome studied was the development of hernias and bulges. Statistical analysis was performed using univariate and multivariate classification and regression tree (CART) analysis. RESULTS: Of the 155 patients, 51 underwent bilateral MS-TRAM flaps and 104 underwent unilateral MS-TRAM flap reconstruction. Thirty-nine patients underwent adjuvant chemotherapy. A statistically significant association was seen between chemotherapy treatment and the incidence of hernias alone (P < 0.05; odds ratio, 6.42; 95% confidence interval, 0.88-73.58). Multivariable CART analyses corroborated these findings and revealed that presence of diabetes mellitus (DM), bilaterality, and receiving chemotherapy treatment were related to increased incidence of hernias (P = 0.011, 0.005, and 0.017, respectively) after controlling for clinical variables such as smoking status, chronic obstructive pulmonary disease, and type of closure. Univariate analyses also revealed a statistically significant association between bilaterality in conjunction with chemotherapy treatment and the incidence of hernias alone (P = 0.0002; odds ratio, 37.56; 95% confidence interval, 4.56-476.35). This highly significant finding is further augmented by multivariable CART analyses, which found that patients who were bilateral and underwent chemotherapy treatment or those with DM were significantly more likely to develop hernias (P < 0.001 and P = 0.016, respectively). CONCLUSIONS: To date, our study is the single largest series of abdominal donor-site complications in patients receiving chemotherapy and free MS-TRAM breast reconstruction. We have demonstrated an increase in the incidence of abdominal donor-site complications, specifically abdominal bulges and hernias, in patients undergoing chemotherapy for advanced stages of breast cancer. This increased complication rate is most pronounced in patients requiring chemotherapy who undergo bilateral reconstruction, and is also a significant risk for patients receiving chemotherapy who have preexisting DM.

The use of a dermal substitute for simultaneous flap delay and donor site coverage in two cases.

OBJECTIVE: Lower extremity traumatic wounds can be difficult to treat owing to limb ischaemia and large zones of injury. Often, muscle or fasciocutaneous flaps are used in the presence of severe open orthopaedic injuries with soft tissue defects. Sometimes local flaps may be the preferred or only option, but may not tolerate being rotated or advanced owing to resulting flap ischaemia. One well-studied technique that can increase the survival of various flaps involves the delay phenomenon. METHOD: In these case reports, Integra Dermal Regeneration template was used to simultaneously create delayed flaps and to cover the wound and flap donor site so that the donor site could be skin grafted at the time of flap inset. RESULTS: These cases demonstrate that use of Integra can enhance the delay phenomenon while simultaneously providing coverage of soft tissue defects in preparation for ultimately insetting delayed flaps and better covering donor areas. CONCLUSION: This technique may be applicable to many different flaps in many different anatomic locations and should be considered an option when reconstructing complicated wounds. DECLARATION OF INTEREST: none.

Effect of hypothyroidism on short-term outcomes after autologous and implant-based breast reconstruction.

Hypothyroidism has high prevalence in elderly women, which overlaps with the patient population who opt for post-mastectomy breast reconstruction. While hypothyroidism was shown to impact outcomes in other surgeries, its effect on breast reconstruction has not been established. This study aimed to compare the short-term outcomes of patients with and without hypothyroidism who underwent autologous (ABR) and implant-based breast reconstruction (IBR), respectively. Patients having ABR or IBR were identified in the National Inpatient Sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between patients with and without hypothyroidism, adjusted for demographics, socioeconomic status, comorbidities, and hospital characteristics. There were 12,765 patients underwent ABR, where 1591 (12.46%) of them had hypothyroidism, while 17,670 patients had IBR with 1,984 (11.23%) having hypothyroidism. Hypothyroid patients had a higher risk of hemorrhage/hematoma (aOR = 1.254, 95 CI 1.079-1.457, p < 0.01) after ABR. However, there were no differences in terms of mortality and organ system complications, nor wound dehiscence, superficial/deep wound complications, seroma, flap revision, excessive scarring, venous thromboembolism, pulmonary embolism, vascular complications, infection, sepsis, transfer out, length of stay (LOS), nor hospital charge between patients with and without hypothyroidism after ABR. All postoperative outcomes were comparable between hypothyroid patients and controls after IBR. While breast reconstruction is generally safe for hypothyroid patients, preoperative screening for hypothyroidism may be beneficial for those undergoing ABR. In ABR, hypothyroidism correction and blood management may help prevent bleeding complications in hypothyroid patients. Future studies should explore the long-term prognosis of hypothyroid patients after breast reconstruction.

African Americans have worse in-hospital outcomes in autologous and implant-based breast reconstruction: a population-based study from the National Inpatient Sample from 2015 to 2020.

African Americans have a long history of disparities in healthcare. However, whether their racial disparity exists in breast reconstruction outcomes is less clear. This study compared short-term outcomes of African Americans and Caucasians who underwent autologous (ABR) and implant-based breast reconstruction (IBR). Patients having ABR or IBR were identified in the National Inpatient Sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between African Americans and Caucasians, adjusted for demographics, socioeconomic status, comorbidities, and hospital characteristics. In ABR, there were 8296 (63.89%) Caucasians and 1809 (13.93%) African Americans. In IBR, there were 12,258 (68.24%) Caucasians and 1847 (10.28%) African Americans. During the same period, 32,406 (64.87%) Caucasians and 7702 (15.42%) African Americans underwent mastectomy, indicating a lower reconstruction rate in African Americans, particularly in IBR. African Americans presented with significant preoperative differences, including younger age, higher comorbid burden, and pronounced socioeconomic disadvantages. After accounting for preoperative differences, in ABR, African Americans had higher renal complications (aOR = 1.575, 95 CI = 1.024-2.423, p = 0.04) hemorrhage/hematoma (aOR = 1.355, 95 CI = 1.169-1.571, p < 0.01), and transfer rate (aOR = 2.176, 95 CI = 1.257-3.768, p = 0.01). In IBR, African Americans had higher superficial wound complications (aOR = 1.303, 95 CI = 1.01-1.681, p = 0.04), flap revision (aOR = 4.19, 95 CI = 1.229-14.283, p = 0.02), and hemorrhage/hematoma (aOR = 1.791, 95 CI = 1.401-2.291, p < 0.01). In both ABR and IBR, African Americans had longer hospital length of stay (p < 0.01). These results highlight evident racial disparities in breast reconstruction for African Americans. Targeted interventions are needed to guarantee equitable access to breast reconstruction services and to address postoperative complications in African Americans.

Preoperative depression is an independent risk factor for short-term morbidities in autologous and implant-based breast reconstruction.

BACKGROUND: Depression is notably common among patients who have undergone mastectomy. Several post-mastectomy patients opt for elective breast reconstruction. However, evidence on the influence of preoperative depression on breast reconstruction outcomes remains limited. This study aimed to evaluate the effect of preoperative depression on the short-term outcomes of autologous breast reconstruction (ABR) and implant-based breast reconstruction (IBR) using a comprehensive national registry. METHODS: Patients who underwent ABR or IBR were identified from the national inpatient sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between the patients with and without depression, adjusted for demographics, primary payer status, hospital characteristics, and comorbidities. RESULTS: Among the 12,984 patients who underwent ABR, 1578 (12 %) had depression whereas 1980 (11 %) out of 17,963 patients who underwent IBR had depression. In ABR and IBR, preoperative depression was associated with higher superficial wound complications (ABR, aOR = 1.386, 95 % CI = 1.035-1.856, p = 0.03; IBR, aOR = 1.281, 95 % CI = 1.001-1.638, p = 0.04), hemorrhage/hematoma (ABR, aOR = 1.164, 95 % CI = 1.010-1.355, p = 0.04; IBR, aOR = 1.614, 95 % CI = 1.279-2.037, p < 0.01), and longer hospital length of stay (p < 0.01). In ABR, patients with depression had higher incidences of infection (aOR = 1.906, 95 % CI = 1.246-2.917, p < 0.01) and sepsis (aOR = 15.609, 95 % CI = 1.411-172.65, p = 0.03). In IBR, patients with depression had higher risks of capsular contracture (aOR = 1.477, 95 % CI = 1.105-1.976, p = 0.01) and seroma (aOR = 1.489, 95 % CI = 1.005-2.208, p = 0.04). CONCLUSION: Preoperative depression is independently associated with major morbidities after ABR and IBR. Preoperative screening for depression can be beneficial. Findings from this study can facilitate preoperative risk stratification and post-operative care for patients with depression.

Concurrent abdominal body contouring and hernia repair are safe choices: An analysis of the 2015-2020 ACS-NSQIP database.

BACKGROUND: Concurrent hernia repair (HR) with abdominal body contouring procedures (ABD), panniculectomy, and abdominoplasty, has been discussed as a strategy. The purpose of this study is to evaluate potential medical and surgical complications following concurrent ABD-HR, with a greater emphasis on cosmetic abdominoplasty. METHODS: The 2015-2020 ACS-NSQIP datasets were utilized to identify patients who underwent ABD or ABD-HR. Propensity score (PS) matching was used to reduce selection bias by equating groups (ABD vs. ABD-HR) based on covariates. Bivariate analyses of independent variables by our outcomes of interest were performed using the Pearson Chi-Square and Fisher's Exact tests for categorical variables and the Wilcoxon rank-sum test for continuous variables. RESULTS: Of the 14,115 patients identified in the ACS-NSQIP, 13,634 had ABD, while 481 had both ABD and HR. Following PS-matching of the cohorts, ABD (n = 481) and ABD-HR (n = 481), bivariate analysis of the combination of incisional, umbilical, and epigastric hernias indicated longer operative times (mean: 209.6 min) (P < 0.001) and a longer hospital length of stay (mean: 1.9 days) (P < 0.001). The incidence rate of postoperative complications such as wound dehiscence, deep venous thromboembolism, DVT, unplanned return to the OR within 30 days, and other medical complications revealed no significant differences between the two cohorts. A sub-group analysis of wound complications found no significant difference for any wound type. Analysis was also conducted for each type of hernia separately, yielding the same results. CONCLUSION: Our results show no increase in postoperative morbidity when combining ABD and HR compared to ABD alone, suggesting that these procedures can be safely performed concurrently and regardless of the type of hernia.

Microsurgery in the Sickle Cell Trait Population: Can it Be Safely and Successfully Performed?

Free-tissue transfer reconstruction in patients with sickle cell anemia risks failure due to polymerization of sickle hemoglobin within the flap microcirculation. However, outcomes vary, as the amount of polymerization is dependent on factors such as disease phenotype/diagnosis, degree of hypoxia, and intracellular dehydration. Most of the literature focuses on patients with sickle cell disease, which produces higher concentrations of sickle hemoglobin and, therefore, is a contraindication to microvascular reconstruction. Fewer reports describe microsurgery in patients with sickle cell trait (SCT) who carry the heterozygous phenotype. Here, we present a case in which a patient with SCT underwent microsurgical breast reconstruction with deep inferior epigastric perforator free-tissue transfer. The 52-year-old woman had previously experienced a failed alloplastic-based reconstruction after radiation therapy for breast cancer. In our case, clinical and Doppler examinations demonstrated that arterial and venous anastomoses had remained patent; so the patient was discharged on postoperative day 4. Blistering developed on postoperative day 8, and by day 15 there was partial necrosis of the inferior-lateral aspect of the deep inferior epigastric perforator flap. Debridement and closure resolved the issue, and at 5 months postprocedure, the flap remained well-perfused and well-incorporated. This case, presented here with patient consent, reports a successful outcome of microsurgical reconstruction in a patient with SCT. It expands the limited evidence to support the safety and feasibility of autologous surgical interventions for patients with the heterozygous phenotype of sickle cell anemia.

Complications Following Breast Augmentation In Transfeminine Individuals: A Systemic Review And Meta-Analysis.

BACKGROUND: Breast augmentation is the most commonly performed procedure for gender affirmation in transfeminine individuals. While adverse events among breast augmentation in cis-gender females were well-described, their relative incidence in transfeminine individuals patients is less elucidated. AIM: This study aims to compare complication rates after breast augmentation between cisgender females and transfeminine patients and to evaluate the safety and efficacy of breast augmentation in transfeminine individuals. METHODS: PubMed, the Cochrane Library, and other resources were queried for studies published up to Jan 2022. A total of 1864 transfeminine patients from 14 studies were included in this project. Primary outcomes including complications (capsular contracture, hematoma or seroma, infection, implant asymmetry/malposition, hemorrhage, skin or systemic complications), patient satisfaction, and reoperation rates were pooled. A direct comparison of these rates was performed against historical rates in cisgender females. RESULTS: Within the transfeminine group, pooled rate of capsular contracture was 3.62% ((95% CI, 0.0038-0.0908); hematoma/seroma was 0.63% ((95% CI: 0.0014-0.0134); infection incidence was 0.08% (95% CI, 0.0000-0.0054); implant asymmetry was 3.89% (95% CI, 0.0149-0.0714). There was no statistical difference between rates of capsular contracture (p=0.41) and infection (p=0.71) between the transfeminine vs cis-gender groups, while there were higher rates of hematoma/seroma (p=0.0095) and implant asymmetry/malposition (p<0.00001) in the transfeminine group. CONCLUSION: Breast augmentation is an important procedure for gender affirmation, and in transfeminine individuals carries relatively higher rates of post-operative hematoma and implant malposition relative to cisgender females.
