Gender-Affirming Facial Surgery: Experiences and Outcomes at an Academic Center

The Effects of Perioperative Gender-affirming Hormone Therapy on Facial Feminization Surgery Adverse Events, Facial Features Addressed, and Esthetic Satisfaction: A Multimodal Analysis

OBJECTIVE

Facial feminization surgery (FFS) treats gender dysphoria in transfeminine patients by addressing the facial bony and soft tissue components. Individuals seeking FFS may be taking gender-affirming hormone replacement therapy [gender-affirming hormone therapy (GAHT)]. This study aims to better characterize the GAHT's impact on venous thromboembolism (VTE) risk, surgical planning, and outcomes.

METHODS

A systematic review and meta-analysis of the literature were carried out to assess the effect of perioperative GAHT continuation on VTE. Cochrane Q and I2 statistics measured study heterogeneity with the following meta-regression exploring these results. Simultaneously, a retrospective review of the senior author's FFS cohort was conducted to investigate GAHT duration's impact on FFS revision rate, complication incidence, and facial structures operated on.

RESULTS

Eleven articles were included: 602 patients stopped GAHT, of whom 3 VTEs were recorded (0.49%). This is compared with one episode among the 925 who continued GAHT perioperatively (0.11%). Study heterogeneity was low (0%), but limited VTE sample size precluded meta-analytic conclusions. Gender-affirming hormone therapy duration does not impact the incidence of all-cause complications (P = 0.478), wound infection (P = 0.283), hematoma (P = 0.283), or VTE (P = 1). The only procedures significantly less associated with higher GAHT were tracheal shaving (P = 0.002) and mandibuloplasty (P = 0.003). Finally, the FFS revision rate was not associated with GAHT duration (P = 0.06).

CONCLUSION

There is a paucity of data to assess the safety or harm of continuing GAHT in the FFS perioperative period. Thus, a shared provider-patient decision-making process examining the risks and benefits of GAHT perioperative continuation is warranted. As patients seeking gender-affirming care are diverse, a "one-protocol-fits-all" is not appropriate.

Technical Pearls and Pitfalls of Facial Feminization Surgery: A Review of Techniques From a Single Institutional Practice

BACKGROUND

Facial feminization surgery (FFS) is an emerging practice that falls under the broader umbrella of gender-affirming surgery. Various approaches exist to feminize the face, yet few published articles describe in detail the techniques of each component procedure. Considering the diversity of interventions employed, the objective of this manuscript is to highlight FFS techniques utilized by the senior author and create a corresponding media gallery.

METHODS

All patients with the diagnosis of gender dysphoria that were referred to the senior author for FFS consultation between June 2017 and August 2022 were reviewed. Data were retrospectively collected from electronic medical records according to the institutional review board (IRB)-approved study protocol. Data collected and analyzed included demographics, operative documentation, and postoperative follow-up. Multimedia material was collected intraoperatively and postoperatively.

RESULTS

A total of 231 patients underwent 262 operations with a total of 1224 FFS procedures. The average follow-up time was 7.7 ± 11 months. Out of the 262 operations, 24 (9.2%) patients experienced minor complications, including 3 (1.1%) with wound dehiscence, 13 (5.0%) with hematomas, and 14 (5.3%) with postoperative infection requiring antibiotics. Of those, 3 (1.1%) required a return to the operating room for washout or removal of malar implants.

CONCLUSION

Although there is a consensus on the fundamental surgical principles to achieve adequate feminization of the facial architecture, the specific techniques to do so differ according to individual practices. As techniques diverge, so do their risk profiles and outcomes; techniques must, thus, align with patients' interventional goals. The material presented here is one of many that can support trainees and junior surgeons as they build a gender-affirming practice.

Ambulatory facial feminization surgery: a comparative analysis of outcomes and complications

BACKGROUND

To date, there are no studies investigating the safety and outcomes of facial feminization surgery (FFS) as an outpatient procedure. This is the first study of its kind analyzing the outcomes of ambulatory FFS based on a comparison of complications, post-operative emergency department or urgent care (ED/UC) visits, and readmissions between patients who underwent FFS with admission versus same-day surgery.

METHODS

A retrospective analysis was conducted on all patients who underwent FFS in a single integrated healthcare system. Patient charts were reviewed for operative details, complications, post-operative ED/UC visits, readmission, and demographic factors. Major outcomes including complications, readmissions, and ED/UC visits were compared between groups with same-day discharge and post-operative hospital admission.

RESULTS

Of 242 patients included in the study, ED/UC visits were comparable between patients discharged same-day (18.2%) and patients admitted post-operatively (21.6%, p = 0.52). Logistic regression showed no significant difference in the composite outcomes of minor complications, major complications, and readmissions (15.6% for ambulatory versus 19.3% for admission, p = 0.46). Temporary nerve palsy, infection, and hematoma were the most common post-operative complications. However, covariates of a lower face procedure and operative time were shown to have significant differences in the composite complication outcome (p = 0.04 and p = 0.045, respectively).

CONCLUSION

Ambulatory FFS is a safe practice with no associated increase in adverse outcomes including complications, ED/UC visits, and readmission when compared to post-operative admission. Adoption of same-day FFS should be considered by high-volume gender health centers to potentially benefit from increased scheduling flexibility and efficiency, increased access to care, and lower healthcare costs.

Facial Feminization: Middle Third of the Face

Facial feminization surgery (FFS) as applied to the midfacial region targets modifications to the nasal and malar esthetic complexes. Although a global assessment is paramount in achieving desired functional results, most patients benefit from malar feminization in the form of bony and soft tissue augmentation, and nasal feminization in the form of reductive rhinoplasty. For patients with signs of aging, additional interventions in the form of rhytidectomy are powerful adjuncts to feminization. As with FFS techniques directed toward the upper and lower thirds, the overarching goal is to obtain complementary outcomes that enhance facial harmony and beauty.

Developing Gender-Affirming Surgery Curricula for Plastic Surgery Residency and Fellowship via Delphi Consensus

BACKGROUND

Gender-affirming surgery (GAS) is a rapidly growing field within plastic surgery, and residents and fellows must receive appropriate training. However, there are no standardized surgical training curricula. The objective of this study was to identify core curricula within the field of GAS.

METHODS

Four GAS surgeons from different academic institutions identified initial curricular statements within six categories: (1) comprehensive GAS care, (2) gender-affirming facial surgery, (3) masculinizing chest surgery, (4) feminizing breast augmentation, (5) masculinizing genital GAS, and (6) feminizing genital GAS. Expert panelists consisting of plastic surgery residency program directors and GAS surgeons were recruited for three rounds of the Delphi-consensus process. The panelists decided whether each curriculum statement was appropriate for residency, fellowship, or neither. A statement was included in the final curriculum when Cronbach α value was greater than or equal to 0.8, meaning that 80% or more of the panel agreed on inclusion.

RESULTS

A total of 34 panelists (14 plastic surgery residency program directors and 20 GAS surgeons representing 28 US institutions) participated. The response rate was 85% for the first round, 94% for the second, and 100% for the third. Out of 124 initial curriculum statements, 84 reached consensus for the final GAS curricula, 51 for residency, and 31 for fellowship.

CONCLUSIONS

A national consensus on core GAS curriculum for plastic surgery residency and GAS fellowship was achieved by a modified Delphi method. Implementation of this curriculum will ensure that trainees in plastic surgery are adequately prepared in the field of GAS.

Frontal Osteomyelitis and Sinusitis Complication After Type III Frontal Bone Cranioplasty for Facial Feminization

Background: Forehead contouring can be a component of facial feminization surgery (FFS). Its complications have been rarely reported on and are often described as "hypothetical." Methods: A case report of complications from forehead contouring resulting in frontal osteomyelitis and sinusitis. Results: A female patient presented with frontal osteomyelitis, sinusitis, and forehead contour deformity after a type III forehead contouring surgery. She had failed prior treatment including oral antibiotics, IV antibiotics, revision sinus surgery, and revision nasal surgery. For definitive treatment, she underwent an anterior table resection, sinus obliteration with bony contouring, and pericranial flap. Conclusions: Forehead contouring represents a recent significant advancement in FFS and gender-affirming therapy. Descriptions of complications and their management are important when novel therapies such as FFS are introduced. This case demonstrates complications from type III forehead contouring including osteomyelitis, frontal sinusitis, and forehead deformity.

Objective Outcomes of Trichophytic Brow Lift and Hairline Advancement in Facial Feminization Surgery

Importance: The upper facial third is an important area to address in facial feminization surgery (FFS). Objective: This study seeks to quantify the changes in eyebrow, hairline, and forehead heights associated with brow lift and hairline advancement surgery in the transgender patient population. Design, Setting, and Participants: A cohort study performed at an academic medical center. Main Outcomes and Measures: Pre- and postoperative frontal view photographs underwent computer-aided photograph analysis. Brow position, hairline position, and forehead height were measured. Patient self-identified race, ethnicity, as well as other demographic factors were also collected. Results: Forty-six patients underwent FFS with brow lift and hairline advancement with photographs permitting measurement. Eyebrow analysis was performed in 33 patients. Hairline and forehead analyses were accomplished in 30 patients. The mean brow elevation was 4.6 mm across all locations. The forehead reduction achieved was 9.8-11.3 mm. Conclusion and Relevance: Trichophytic brow lifting with hairline advancement outcomes was able to be reliably quantified from standardized clinical photographs. On average, 4-5 mm of brow lift, 6-7 mm of hairline lowering, and 10-11 mm of forehead reduction were achieved, contributing to a more feminine appearance of the upper facial third.

Sex Differences in Adult Facial Three-Dimensional Morphology: Application to Gender-Affirming Facial Surgery

Background: Gender-affirming facial surgery (GFS) is pursued by transgender individuals who desire facial features that better reflect their gender identity. Currently, there are a few objective guidelines to justify and facilitate effective surgical decision making. Objective: To quantify the effect of sex on adult facial size and shape through an analysis of three-dimensional (3D) facial surface images. Materials and Methods: Facial measurements were obtained by registering an atlas facial surface to 3D surface scans of 545 males and 1028 females older than 20 years of age. The differences between male and female faces were analyzed and visualized for a set of predefined surgically relevant facial regions. Results: On average, male faces are 7.3% larger than female faces (Cohen's D = 2.17). Sex is associated with significant facial shape differences (p < 0.0001) in the entire face as well as in each sub-region considered in this study. The facial regions in which sex has the largest effect on shape are the brow, jaw, nose, and cheek. Conclusions: These findings provide biologic data-driven anatomic guidance and justification for GFS, particularly forehead contouring cranioplasty, mandible and chin alterations, rhinoplasty, and cheek modifications.

Developments in facial feminization surgery

PURPOSE OF REVIEW

Facial feminization surgery (FFS) is being performed by facial plastic surgeons with increasing frequency. As insurance companies expand benefits to cover these procedures, more and more institutions are developing programs to treat transgender patients. The purpose of this review is to summarize recent literature on the subject so that those interested in this subject may have a framework to analyze these works.

RECENT FINDINGS

The most significant findings are that FFS does appear to be safe with low complication rates, despite long operative times due to multiple procedures performed. Much of the recent literature is reviews of each practice's techniques. This is valuable to educate those interested in beginning to perform these surgeries. Further, these reviews can eventually be compiled into a standard of care. Virtual surgical planning is currently being used by some departments, but its value is yet to be determined.

SUMMARY

FFS is performed with increasing frequency. Current literature reviews best practices with the goal of eventually establishing a standard of care.
