Hematoma following gender-affirming mastectomy: A systematic review of the evidence

Efficacy of topical tranexamic acid in gender-affirming mastectomy

INTRODUCTION

Bleeding complications, such as hematoma, are frequently encountered after breast surgery. To mitigate these complications, the use of tranexamic acid (TXA), has become increasingly popular in breast procedures. This study aims to investigate the impact of topical moistening of the surgical wound with TXA on the reduction of postoperative bleeding complications in patients undergoing gender-affirming mastectomy (GAM).

METHODS

A single-center retrospective cohort study examined postoperative bleeding outcomes in patients who underwent GAM between April 2014 and March 2024. The use of intraoperative topical TXA was documented, along with rates of hematoma, seroma, and other postoperative complications.

RESULTS

The study included 456 patients: 62 who received topical moistening with 10 mL of 50 mg/mL TXA on each breast and 394 control patients who received standard hospital protocol for intraoperative hemostasis. Postoperative hematoma occurred in 3 patients (4.9%) who received topical TXA and 18 patients (4.6%) who did not (p=0.92). The incidence of other postoperative complications did not significantly differ between the groups.

CONCLUSION

This study found no statistically significant differences in postoperative bleeding complication rates between patients who received TXA and those who followed the standard hemostasis protocol. Although our results suggest that topical TXA is safe and does not increase thromboembolic risk, its efficacy in reducing bleeding complications in GAM patients remains uncertain. The study's limitations, including its single-center design and small sample size, highlight the need for larger, multicenter randomized trials to establish the role of topical TXA in improving postoperative outcomes for GAM procedures.

Topical Tranexamic Acid and Chest Masculinization Surgeries-Impact on Postoperative Hematoma Incidence

Introduction

Postoperative hematoma requiring intervention occurs more frequently in chest masculinization surgeries than in other types of breast surgeries, with incidences ranging from 0.7% to 13.2% per patient. Although there is increasing evidence that topically applied tranexamic acid (TXA) effectively reduces postoperative bleeding in breast surgeries, its impact on masculinization surgeries is understudied.

Aims

Examining the significance of topical TXA in reducing postoperative hematoma in chest masculinization surgeries.

Methods

This retrospective cohort comprises female-to-male transgender and non-binary patients who underwent chest masculinization at Helsinki or Tampere University hospitals between 2018 and 2024. Topical TXA (20 mg/ml, 25 ml per breast) was incorporated into routine use in October 2022, replacing the previous practices; Helsinki mainly operated without TXA, whereas Tampere routinely used intravenous (i.v.) TXA.

Results

A total of 198 patients undergoing chest masculinization surgery were included. Among them, 9 (4.5%) major hematomas occurred. The need for reoperation due to postoperative hematoma was lower in the topical TXA (3.2%, 2 out of 63 patients) and i.v. TXA (3.4%, 2 out of 58 patients) groups compared to the non-TXA group (6.5%, 5 out of 77 patients). Subpectoral incisions (71.2%, 141 patients) resulted in a 5.0% hematoma rate, whereas periareolar incisions (28.8%, 57 cases) had a 3.5% hematoma rate.

Conclusions

Our study suggests that topical and i.v. TXA effectively reduce postoperative bleeding in chest masculinization surgeries, with similar outcomes between the 2 methods. Albeit our results lack statistical significance and they support the potential benefit of prophylactic TXA use in hematoma reduction.

Comparative Outcome Study of Gynecomastia Surgery and Gender-Affirming Mastectomy With 100% Nipple Preservation

BACKGROUND

Gynecomastia and gender-affirming top surgery share similarities in objectives. Traditionally, a subcutaneous mastectomy using a semicircular incision has been recommended for most gynecomastia patients. In recent years, mastectomies and nipple grafting have become the most popular treatment for gender-affirming top surgery. Nipple grafting is very debilitating to this unique body part, which also provides erogenous sensation. This study was undertaken to compare methods, complications, and outcomes using an approach that preserves nipples in 100% of patients.

METHODS

A retrospective study was conducted, comparing all gynecomastia patients and gender-affirming top surgery patients treated by the author over the period 2016-2024. Most (92%) gynecomastia patients were treated with liposuction in combination with a semicircular incision and subcutaneous mastectomy. Twelve top surgery patients (71%) were also treated with this method. Two gynecomastia patients and 5 top surgery patients with pendulous breasts underwent vertical mammaplasties incorporating a medial pedicle. A telephone survey was also administered.

RESULTS

Fifty-three patients were evaluated, including 36 gynecomastia patients and 17 top surgery patients. The complication rate was 21%. Three patients (6%) developed hematomas. Five patients (9%) underwent revisions. No patient experienced complications of the nipple/areola complex. All surveyed patients reported that nipple preservation was important. Two patients (11%) reported reduced nipple sensation after surgery. No patient reported scar dissatisfaction. Fifteen patients (83%) were comfortable exposing their chest after surgery, compared with 1 patient (6%) before surgery.

DISCUSSION

Today, a major disparity exists in treatment recommendations, with almost all gynecomastia patients being offered nipple-preserving methods and the majority of top surgery patients undergoing mastectomies with nipple grafting, or even without grafting. In view of the importance of nipple sensation, and the success of an alternative approach, surgical priorities should be realigned to preserve nipple/areola complexes.

CONCLUSIONS

Nipple preservation is offered to all patients. Subcutaneous mastectomies are often sufficient, and limit scarring. Vertical mammaplasties with a medial pedicle are effective in patients with pendulous breasts. Liposuction is offered as a second-stage procedure, although many patients are satisfied with some residual breast fullness. The need for secondary surgery of the nipple/areola complex and scar revisions is minimized.

Breast Reduction Epidemiology and Complications in Nonbinary, Transgender, and Cisgender Adults

INTRODUCTION

Research in gender-affirming chest surgery has primarily compared cisgender versus transgender and gender-diverse (TGD) people, without specifically addressing nonbinary people. This study will assess surgical complications between cisgender, transgender, and nonbinary adults undergoing breast reductions.

METHODS

The National Surgical Quality Improvement Program databases from 2015 to 2021 were used to identify TGD patients who underwent breast reduction (Current Procedural Terminology code: 19318) and cisgender patients who underwent this procedure for cosmesis or cancer prophylaxis. Analysis of variance tests, chi-squared tests, unpaired t-tests, and regression models compared complications among cisgender, transgender, and nonbinary patients.

RESULTS

A total of 1222 patients met the inclusion criteria: 380 (31.1%) were cisgender, 769 (62.9%) were transgender, and 73 (6.0%) were nonbinary. The proportion of TGD patients grew significantly relative to cisgender patients over the study period (P < 0.001). The overall all-cause complication rate was 3.4%, with 4.2% of cisgender, 1.4% of nonbinary, and 3.1% of transgender patients experiencing surgical complications. After adjusting for confounding variables, no statistically significant difference was observed in all-cause complication rates between the cohorts. In the sample, 19 transgender patients (2.5%) underwent reoperation. Transgender patients had a lower likelihood of wound complications (odds ratio: 0.172; 95% confidence interval: 0.035-0.849; P = 0.031) compared to cisgender patients and nonbinary patients. None of the patients experienced a severe systemic complication.

CONCLUSIONS

The findings emphasize the growing demand and safety of gender-affirming breast reductions. They underscore the importance of continued research and tailored approaches to delivering care to nonbinary and transgender patients, addressing their diverse needs and improving access to gender-affirming surgeries.

Gender-affirming surgeries for transgender and gender diverse individuals and associated health outcomes

Gender-affirming care is treatment that recognizes and affirms the gender identity of transgender and gender-diverse (TGD) individuals. Though not all TGD people choose to surgically transition, gender-affirming surgeries (GAS) are an important part of many TGD people's transition. GAS can include a wide array of procedures aimed at aligning an individual's physical characteristics and gender identity. This review describes the most common procedures considered to be GAS, detailing important relevant considerations for each procedure. These include transfeminine procedures (i.e., breast augmentation, penile inversion vaginoplasty, orchiectomy, tracheal shave, and facial feminization); transmasculine procedures (i.e., chest masculinization, hysterectomy, phalloplasty, and metoidioplasty); and other procedures (i.e., fertility preservation and hair removal). Patient outcomes and the legal landscape for GAS are also discussed to contextualize these procedures within largest discourses surrounding gender-affirming care.

Use of Tranexamic Acid in Gender-Affirming Mastectomy Reduces Rates of Postoperative Hematoma and Seroma

BACKGROUND

The established safety and efficacy of tranexamic acid (TXA) in minimizing perioperative blood loss has led to increased interest within plastic surgery. Prior studies have demonstrated decreased edema and ecchymosis and reduced rates of postoperative collection with administration of TXA; however, its use has not been reported in gender-affirming mastectomy. This represents the first study to evaluate the effects of TXA on postoperative outcomes in patients undergoing gender-affirming mastectomy.

METHODS

A single-center cohort study was performed analyzing all consecutive patients undergoing gender-affirming mastectomy with the senior author (R.B.-L.) between February of 2017 and October of 2022. Beginning in June of 2021, all patients received 1000 mg of TXA intravenously before incision and 1000 mg at the conclusion of the procedure. Patients were stratified according to intraoperative administration of TXA, with demographic characteristics, surgical characteristics, and postoperative outcomes compared between groups.

RESULTS

A total of 851 patients underwent gender-affirming mastectomy. Of these, 646 cases were performed without TXA, and 205 patients received intravenous TXA intraoperatively, as described previously. Patients who received TXA had significantly lower rates of seroma (20.5% versus 33.0%; P < 0.001) and hematoma (0.5% versus 5.7%; P = 0.002). There was no difference in rates of surgical-site infection ( P = 0.74). TXA use was not associated with increased rates of venous thromboembolism ( P = 0.42).

CONCLUSIONS

Intraoperative administration of TXA in patients undergoing gender-affirming mastectomy may safely reduce the risk of postoperative seroma and hematoma without increased risk of thromboembolic events. Additional data collection and prospective studies are warranted to corroborate these findings.

Patterns of Perioperative Hormone Therapy for Gender-Affirming Surgery

INTRODUCTION

There is no consensus regarding perioperative hormone replacement therapy (HRT) for gender-affirming surgery (GAS). Common concerns for continuing perioperative HRT included risk of deep vein thrombosis (DVT) or hematoma. However, discontinuing HRT is not risk free and may cause mood swing or increased anxiety. Our study aimed to investigate current patterns of HRT before GAS worldwide.

METHODS

The first stage of Delphi technique was implemented by sending a 27-item survey to all surgeons (total n = 150; 94 plastic surgeon, 35 urologist, and 21 gynecologists) of the World Professional Association for Transgender Health who perform GAS. Survey themes included the hormone type, duration, and usage of DVT prophylaxis.

RESULTS

Overall survey response rate was 34% (total n = 51; 8 urologists, 35 plastic surgeons, and 8 gynecologists). The majority of surgeons are US-based (n = 39, 76%). The most common HRTs are in injection form (n = 28, 55%). The majority of surgeons do not stop HRT before GAS and do provide DVT prophylaxis to all patients <1 week after GAS. The most common procedure that surgeons discontinue HRT is feminizing bottom surgery (43%). For surgeons who discontinue HRT before GAS, there is a wide variation on discontinuation schedule.

CONCLUSIONS

There is considerable variation in perioperative HRT patterns for GAS. Further research is needed to develop a data-driven consensus guideline to provide high quality of care for transgender and nonbinary patients.
