Breast augmentation in the transgender patient: narrative review of current techniques and complications
Introduction
Any discussion of gender-affirming surgery (GAS) for transgender patients should begin with an examination of the field’s history. Regrettably, care for transgender patients has been obstructed on the individual and systemic levels. While gender affirming procedures have long-existed, awareness of transgender-specific surgical needs was propelled by Dr. Harry Benjamin and his care for Christine Jorgenson, an American actress and army veteran who publicly sought feminizing transition (1). Through his efforts, Dr. Benjamin laid the groundwork for GAS in the public sphere (1).
In the United States of America, as many as 0.6% of adults or 1.4 million people, currently identify as transgender; worldwide estimates of the transgender population range from 0.4% to 1.3% (2). Estimates show a slightly higher representation of transfeminine individuals (1:11,900 to 1:45,0000) when compared to transmasculine individuals (1:30,400 to 1:200,000) (3). Regional variation exists as well with some locations, such as the District of Columbia, reporting percentages of transgender individuals as high as 2.8% (2). Of note, formal epidemiologic studies on the true population of transgender individuals are challenging. Estimates often come from single institution data, which are then extrapolated to state-wide or nation-wide scales (3). These numbers only capture data on patients who both have access to transgender-specific healthcare and experience gender dysphoria to a degree in which transgender-specific healthcare is required (3-5). Gender dysphoria can be defined as the discrepancy between assigned sex at birth and gender identity that leads to discomfort or distress (3). The true population of transgender individuals is likely higher than reported.
In 1981, GAS was excluded as a covered expense by the United States Department of Medicare (1). It was not until 2014, that this ruling was overturned as research demonstrated the safety, efficacy, and non-experimental nature of GAS (1,6). Insurance coverage of GAS has been a well-documented barrier to healthcare access that is finally beginning to shift (7,8). Lane et al. analyzed Truven MarketScan data from 2009 and 2015 for all encounters coded for gender identity disorder, and their analysis discovered year-by-year increases in GAS utilization (9). Canner et al. performed a large-scale analysis of all inpatient healthcare encounters for transgender patients using 14 years of data from the National Inpatient Sample (NIS) (10). Their group discovered a three-fold increase in Medicare and Medicaid coverage for transgender patients in 2014 with incidence of GAS rising in parallel to the increased insurance coverage (10).
Unfortunately, healthcare coverage remains tumultuous as inclusions under Section 1557 of the Affordable Care Act continue to be debated. On June 12, 2020, the Department of Health and Human Services redefined discrimination of sex as strictly biological sex instead of the Obama-era definition including sexual orientation and gender identity, opening an avenue for insurance companies to decline payment and reimbursement (11). Three days later the Supreme Court ruled in a historic 6-3 decision that sex included gender identity and sexual orientation in a case regarding Title VII of the Civil Rights Act, setting the stage for lawsuits to challenge the Department of Health and Human Services’ reversal of transgender protection. While more work is necessary to topple pervasive exclusion from healthcare, our field is on track to increasingly provide for transgender patients.
We aim for this review to increase provider understanding of transfeminine breast augmentation. This review will take readers through (I) preoperative evaluation and guideline adherence (II) operative considerations unique to transfeminine patients and (III) early and late postoperative care. We present the following article in accordance with the Narrative Review reporting checklist (available at http://dx.doi.org/10.21037/atm-20-5087).
Methods
Literature review
We conducted a literature search for papers published up to the year 2020 on the approach to breast augmentation in transfeminine patients. Databases used in this search included PubMed and Ovid MEDLINE. Various MeSH terms, such as “Transgender”, “Transgender Persons”, “Gender Dysphoria”, “Gender Confirmation Surgery”, “Gender Confirmation Procedures”, and “Mammaplasty”, and keywords, such as “Transfeminine”, “Breast Augmentation”, and “Top Surgery”, were used to identify articles for inclusion in this review. Articles were limited to those published in the English language.
An initial pull of 5,803 articles was identified using these parameters. After screening article titles and abstracts, 59 papers and their reference lists were included for full-text review. While an exhaustive systematic review was not performed, standard systematic review methodology was used to ensure high-quality information was obtained for this review.
Surgical experience data
Transfeminine patients undergoing implant-based breast surgery between 2018 and 2020 were retrospectively reviewed. Patient demographics, such as age and race, and comorbid conditions, such as BMI, smoking history, and Charlson comorbidity index (CCI), were collected (12). Details on the surgical procedure, such as implant size, incisional location, and implant plane, were collected. A total of 37 patients were included.
Preoperative guidelines, evaluation, and considerations
Since 1979, the World Professional Association for Transgender Health (WPATH) has outlined Standards of Care (SOC) as clinical guidance for providers offering surgical and nonsurgical gender-affirming care. The SOC draws on current research to provide both mandatory and suggested components of the preoperative workup for transfeminine patients seeking top surgery. Before surgery, all patients must be at an accepted age for consent, and all patients must have the capacity to give informed consent (3). All transgender patients must have well-documented, persistent gender dysphoria before surgical intervention is undertaken (3). The SOC mandates that all transfeminine patients seeking breast augmentation receive one referral from a qualified mental health professional. Significant medical or mental health concerns must be appropriately managed preoperatively (3). While not mandatory, the SOC suggest that all transfeminine patients take exogenous hormones for a minimum of twelve months (3). This suggestion is to maximize an increase in parenchymal breast tissue, leading to a better cosmetic outcome after breast augmentation. In order to fulfill requirements and suggestions outlined in the SOC, a multidisciplinary team should be involved early in the preoperative period. Endocrinologists or primary care doctors experienced with transgender care can manage exogenous hormone use. Psychiatrists specializing in transgender health are needed for referrals and are instrumental in ensuring all psychiatric concerns are well-managed.
The preoperative period is especially important when offering surgical care to transgender patients. From the first patient visit, all providers must establish a respectful and equitable relationship. Unfortunately transgender patients face higher rates of suicidality, physical assault, sexual abuse, and lethal violence when compared to cisgender peers (13). Specific to healthcare, transgender patients report alarmingly high rates of unsupportive, ill-informed, and hostile physicians (13). Providers can work to overcome this history by affirming the patient’s gender identity and inquiring about the patient’s preferred name and pronouns (14). Patient preferences may not align with a particular gender or identity category, so providers must document what the patient prefers. Patients may refer to breast augmentation as “top surgery,” so it is important to acknowledge and document a patient’s preferred way of speaking about their procedure.
For transfeminine breast augmentation, providers must take a detailed patient history that focuses on any steps the patient has taken in the chest feminizing process. As previously mentioned, exogenous hormones should be taken for at least a year to prepare for surgical augmentation by maximizing growth of native tissues (15). Some groups advocate for stopping exogenous hormone use approximately two to four weeks prior to surgery (16). The thought is that exogenous estrogen increases the risk of thromboembolic events. However, this practice is controversial due to low incidence of thromboembolic events coupled with the deleterious effects of stopping hormone use in the transgender population (16). In our practice, we no longer stop exogenous hormone use, and we have not documented any changes in thromboembolic event frequency.
Unfortunately, some transfeminine patients seek “street” hormones and illicit silicone injections as an alternative to physician-prescribed gender affirming medications and procedures. These substances have been issued warnings by the U.S. Food and Drug Administration, but the low-cost and the ability to obtain these substances outside of the medical setting make them unfortunately attractive options for patients who distrust or cannot access the medical community (17,18). If a history of self-obtained substances is disclosed, providers should take this into account when formulating a surgical plan (19). In our practice we see a significant number of patients, who use both street hormones and illicit silicone injections. The 2015 U.S. Transgender Survey (USTS) discovered that approximately 8% of those surveyed used street hormones and 3% used illicit silicone injections (20). These numbers are estimated to be as high as 29–63% in urban transgender patient populations (21). Analysis of our transgender patients undergoing breast augmentation reveals that 21.5% of patients used street hormones, illicit silicone injections, or both in an attempt to meet their gender actualization needs. Despite these high rates of use, complication rates were incredibly low with no patients requiring revision. Breast augmentation can, in our opinion, be safely performed in patients with a history of illicit augmentation substance use as long as appropriate evaluation and expectation management is performed. Patient demographics and comorbid conditions are outlined in Table 1.

For all patients, systemic illnesses and medications must be assessed preoperatively to ensure risk of complications is reduced. Breast surgery impairs tissue vascularity, so any agents that cause vasoconstriction, such as nicotine, cocaine, and methamphetamines, must be stopped preoperatively (16). 40.5% of our transfeminine patients have some degree of tobacco history, highlighting the prevalence of tobacco use and the importance of screening for its use. Wound healing capabilities are maximized with smoking cessation as well (15). In patients with diabetes, HbA1c should be below 7.0% to minimize cardiovascular and infectious complications (16).
Surgical techniques
The most common method for transfeminine patients to achieve their desired chest appearance involves the surgical placement of implants. Surgical breast augmentation is very similar in transgender and cisgender patients, overall. Transgender-specific recommendations for implant sizing and selection, incision placement, and operative plane are developing (22). Providers must account for certain differences in their transgender patients in order to provide the optimal surgical and aesthetic outcomes. Figure 1 outlines considerations that should be made in the breast augmentation process.

The genetic male and genetic female anatomy differ in a few aspects that are necessary to evaluate and account for during transfeminine breast augmentation. A genetically male individual has years of exposure to androgenic hormones that develop relatively broad shoulders, wide sternum, shortened nipple to inframammary fold distance, hypertrophied pectoralis majors, and small, ovoid, lateralized nipple areolar complexes (NAC) (23,24). Transfeminine patients who take exogenous hormones commonly develop asymmetric breast tissue growth. Certain operative techniques can accommodate these differences and yield highly satisfactory surgical outcomes.
In the transfeminine patient, sizers are helpful to determine the best implant size to achieve a symmetric result. 16.2% of our transfeminine patients require implants of different size to achieve symmetry, with difference in volumes averaging 46.7 cc (SD 18.3). Genetic males often have a small, lateralized NAC. Achieving a feminized NAC requires both size increase and centralization of this structure. Size is often somewhat increased with the placement of implants, since they stretch the overlying skin (24). Implants should be placed directly behind the nipple, and implants with wider base width can help to balance nipple position and cleavage formation. In extreme lateralization, centralization of the NAC can be achieved via periareolar mastopexy. This procedure can be performed simultaneously with breast augmentation in experienced providers. Patients must be counseled of the risk carried by this additional procedure and incision location—nipple sensitivity changes, NAC necrosis, etc. Similarly, breast implant lateralization due to hypertrophied pectoralis major can be compensated for with elevation of medial pectoralis major fibers. However, over-elevation will lead to challenging medial migration of implants and symmastia.
Preoperatively, patient and provider must agree on implant sizing, implant selection, incision location, and operative plane. Of note, several studies demonstrate that provider and patient ideals for breast augmentation differ widely, with patients often desiring larger breasts with defined cleavage (24). In a 20-year follow-up study of transfeminine patients who had undergone breast augmentation, the most common reason for secondary procedures was to increase implant size (25). At revision, implant size increased significantly, with an average size increase of 107.0 cc (SD 48.1 cc) compared to the primary implants (25). Average initial implant size increased over the study period as well, indicating increased desire for larger breasts (25). It is imperative that providers counsel patients preoperatively about the limitations on size due to the native breast skin envelope and nascent breast tissue. Other authors report that more than half of their patients would select larger implant sizes if not for anatomic and operative restrictions (26). On average, implant size for our transfeminine patients is 448.1 cc (SD 121.4 cc) (Figure 2A,B).

Breast augmentation incision location for transfeminine patients can include any of the standard techniques used for cisgender patients—axillary, inframammary, or periareolar (27). In inframammary incisions, the new inframammary fold (IMF) should be placed lower than the native line to accommodate the future downward implant settling (27). This is especially important in transfeminine patients since failure to lower the IMF results in excessive upper pole fullness and a downward facing NAC (26). Mallucci and Branford proposed a simple, prospectively validated method for calculating the ideal location of the IMF incision. The “ICE” method takes the implant dimensions (I), breast capacity (C), and excess tissue (E) into account in the equation, I – C = E (28). I represents half of the implant height plus the projection; C is the nipple-to-IMF distance when the breast tissue is stretched; E is the distance by which the IMF must be lowered (28). The Ranquist formula is another useful system for appropriate lowering of the IMF. This formula uses the base width of the implant to suggest the new nipple to IMF distance (Table 2). For our transfeminine patients, we routinely use the Ranquist formula, and find that on average the IMF should be lowered at least 3 cm.

The implant plane for transfeminine breast augmentation is commonly in the prepectoral or subpectoral plane (25). Both methods have been used with success, but certain patient characteristics should sway provider decision on which plane to use. Tebbetts and Adams proposed a comprehensive algorithm for choosing the appropriate implant and procedural characteristics known as the High Five or TEPID system (29). Their group suggests dual-plane or partial subpectoral implant placement in patients with a “pinch test” less than 2.0 cm (29). A pinch test is performed by gently grasping native breast tissue superior to the NAC between the thumb and index finger. Implant plane placement based on pinch test results helps to reduce concerns with postoperative malposition or animation deformity. The pinch test has recently been adapted into a transfeminine-specific algorithm for plane selection (26). This updated algorithm suggests using the prepectoral plane in patients with a “pinch test” >1.5 cm and skin softening coupled with signs of androgen exposure Mallucciexcess sternal bone width and pectoral hypertrophy (26). Of note, their group recommends that patients who have a history of silicone injections should receive dual-plane subpectoral placement regardless of tissue characteristics (26). In our practice, we routinely use the prepectoral plane for patients with Tanner stage IV or V breast development, due to lower postoperative pain levels (27). Prepectoral implant placement may lead to higher rates of capsular contracture and a more lateralized breast (30). The majority of our transfeminine patients (n=34, 91.9%) undergo prepectoral implant placement. Few of our patients (n=3, 8.1%) require dual plane implant placement. Since revisions are more challenging to perform and it is difficult to obtain insurance coverage, we recommend thorough preoperative discussion of these risks and benefits. Of note, we do not routinely use drains in our breast augmentation practice (Figures 3A,B,C,D,4A,B,C).

Fat grafting is a useful adjunct to breast-implant placement to achieve desired volume. Fat grafting is rarely used as the sole method of transfeminine breast augmentation. However, this procedure is especially useful for reducing implant visibility and palpability and it offers a more natural appearing counter (16,27). Take rates for fat grafting range from 50–60%, so multiple procedures are often needed to achieve the desired outcome (15,27). Unfortunately, fat grafting is not routinely covered by insurance, and patients must pay out of pocket for this procedure. Having to pay out of pocket limits frequency of this procedure.
Of note, use of textured implants cannot be recommended for transfeminine patients due to the risk of anaplastic large cell lymphoma (ALCL). Case reports indicate that textured implant placement in transfeminine patients is linked to ALCL.
Postoperative care
The immediate postoperative care of transfeminine patients undergoing breast augmentation is similar to the care for cisgender patients. All postanesthesia care unit workers should be trained to care for transgender patients (31). Transgender patients face disproportionate amount of prejudice and hostility within the medical setting. Their immediate postoperative setting places them at increased vulnerability. All stuff must be trained on respectful terminology and pronoun use. Short-term care involves implant massage to soften the overlying breast skin and proper brasserie fitting (16). We recommend that patients avoid heavy lifting for at least four to six weeks (15).
Long-term postoperative care involves implant imaging and breast cancer screening. Breast implants are not classified by the FDA as lifetime devices. For silicone implants, patients should undergo magnetic resonance imaging (MRI) three years after implantation and every two years after that (15). Transfeminine patients who have taken exogenous hormones for at least five years and are 50 years or older should begin breast cancer screening. Although rare, all patients should be counseled on breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), which is related to textured implant placement (32-34). Presenting symptoms include late-onset fluid collection, overlying skin discoloration, and pruritis (33). We do not recommend use of textured implants for transfeminine breast augmentation. Patients who underwent a previous augmentation with a textured implant should be informed of the risk of BIA-ALCL, its symptoms, and avenues for implant exchange.
Complications
Complication rates in breast augmentation are low, regardless of whether the procedure is performed in cisgender or transfeminine patients. Recently, Cuccolo et al. reviewed 10 years of data from the National Surgical Quality Improvement Program (NSQIP) database. On dividing breast augmentation patients into cisgender and transfeminine cohorts, they identified low (1.8% versus 1.6%, respectively) and non-statistically different rates of 30-day complications (P=0.890) (35). Lane et al. investigated complication incidence over the full spectrum of GAS using data from TruvenMarket scan (9). In this catch-all analysis, total complications occurred in only 5.8% of operations. Of note, complications were lowest in breast-based procedures and highest in genital-based procedures. However, complications affect certain subpopulations disparately. Using data from NSQIP and the National Inpatient Sample (NIS), Tran et al. identified that being of black or African American race increased risk of reoperation and readmission independent of all other factors (36).
Long-term complications of breast implantation in transfeminine patients are the same as those in cisgender patients—symmastia, capsular contracture, reduced breast or nipple sensation, implant leakage, or implant migration. Anecdotally, revisional procedures in transfeminine patients are challenging due to already thin breast tissue and skin coverage. However, secondary procedures can be undertaken and produce acceptable results. Of note, revisional procedures are often not covered by insurance. We suggest thorough preoperative discussion with patients about this. Overall, implant-based breast augmentation remains a safe procedure. Patient regret after breast augmentation, while rare, occasionally occurs. A study noted that 0.6% of transfeminine and 0.3% transmasculine patients who underwent genital-based gender affirming surgery felt some degree of regret after 30-years of follow-up (37). Data on breast or chest-based procedures remains lacking. Supposed reasons for postprocedural regret include poor operative outcomes, surgical complications, and lack of social support from family and partners (38).
Conclusions
Breast augmentation is often a critical step in a transfeminine patient’s surgical experience. With thorough understanding of the unique personal and anatomic needs of transfeminine patients, providers will make appropriate breast augmentation decisions. This understanding allows providers to perform this procedure safely with highly acceptable aesthetic and patient satisfaction results. Complication rates are low and are comparable to those seen in cisgender patients undergoing analogous procedures. As the social and political climate continues to evolve, we anticipate increased numbers of transfeminine patients seeking breast augmentation.
