The Type I+ Forehead in Facial Feminization Surgery.

BACKGROUND: Feminizing fronto-orbital reconstruction involves one of four possibilities with the Ousterhout Type III anterior table frontal sinus osteotomy and setback performed in most patients while the Type I reduction recontouring is reserved for patients without frontal sinuses or thick anterior tables. However, patients with frontal sinuses and either a moderately thick anterior table or a shallow frontal sinus in the sagittal plane represent an intermediate morphology. For such morphologies, we introduce the novel Type I+ fronto-orbital reconstruction technique, consisting of frontal bone recontouring supplemented with anterior table reconstruction and split cranial bone graft. METHODS: Transgender and gender non-conforming patients who underwent Type I+ or Type III feminizing fronto-orbital reconstruction (2019-2023) were included for retrospective review and comparison of techniques. RESULTS: In the 123 patients (mean age 32.2 ± 9.5 years) included, 6.5% underwent Type I+ and 94.5% underwent Type III feminizing fronto-orbital reconstruction. Morphologically, Type I+ patients displayed a shallower frontal sinus compared to Type III patients (median anterior to posterior table depth 4.1[interquartile range, IQR, 1.1-5.0] versus 9.8[IQR 7.5-12.0]mm, p<0.001). At the maximum prominence, Type I+ patients also demonstrated thicker anterior tables compared to Type III patients (median 6.6[IQR 5.0-8.8] versus 2.2[IQR 0.4-4.7]mm, p=0.001). Patients receiving Type I+ procedures underwent an anterior table reduction of 2.7±1.2mm versus 4.2 ± 1.2mm for Type III procedures in the sagittal plane (p=0.002). CONCLUSIONS: The current work introduces a novel solution to an intermediate frontal sinus phenotype for gender-affirming facial feminization surgery.

Patient-Reported Preoperative Depression as a Predictor of Psychosocial Outcomes After Gender-Affirming Facial Feminization Surgery.

OBJECTIVE: To understand psychosocial functioning before and after gender-affirming facial feminization surgery (FFS) as well as identify predictors of postoperative psychosocial functioning. SUMMARY BACKGROUND DATA: Few investigations have rigorously explored the impact of gender-affirming FFS on psychosocial functioning in transgender and gender non-binary (TGNB) individuals. This knowledge gap hinders the identification of methods to optimize mental health quality-of-life outcomes after FFS and carries repercussions for access to care. METHODS: Adult TGNB participants awaiting gender-affirming FFS were prospectively enrolled and administered Patient-Reported Outcomes Measurement Information System (PROMIS) instruments assessing anxiety, anger, depression, global mental and physical health, positive affect, emotional support, social isolation, companionship, and meaning and purpose before and 3-6 months after FFS. Paired t-tests compared pre- and postoperative scores. Multivariable linear models identified predictors of postoperative psychosocial outcomes. RESULTS: Among the domains, psychosocial scores improved for anxiety, depression, global mental health, social isolation, and positive affect after FFS. When accounting for potential variables contributing to postoperative psychosocial scores including other gender-affirming surgeries, hormone therapy duration, and private versus public insurance type, we found that preoperative depression scores independently predicted the variance in all other postoperative scores with global mental health (ß=-0.52, 95%CI -0.58--0.31 P<0.001), anxiety (ß=0.40, 95% CI 0.21-0.51, P<0.001), and meaning and purpose (ß=-0.52, 95% CI -0.78--0.42 P<0.001) as the strongest models. CONCLUSIONS: This study suggests that gender-affirming FFS improves psychosocial functioning; however, such improvements are highly influenced by the baseline psychological functioning of each individual. These findings indicate that preoperative psychological functioning may be a potential avenue for improving outcomes after FFS via perioperative psychological interventions.

Estrogen hormone therapy stabilizes lateral hairline in transfeminine patients: Implications for facial feminization surgery.

BACKGROUND: Although several studies report on the suppressing effects of estrogen therapy on facial and body hair in transgender and nonbinary (TGNB) individuals, few studies have elucidated its effects on hairline stability on the scalp. In this study, we assessed the influence of estrogen therapy on forehead length. METHODS: All TGNB patients, aged 30 years or older, assigned male at birth (AMAB) seeking facial feminization surgery were included in the study. Central and forehead lengths were collected at the initial consultation visits. Variables, including age, duration of hormone replacement therapy (HRT), presence of spironolactone, and presence of other hair treatments, such as finasteride, dutasteride, or minoxidil, that potentially influence hair growth were collected by chart review. Multivariable linear regressions were constructed with relevant predictor variables while also incorporating global health scores as a proxy for psychological effects on hair loss. RESULTS: Overall, 171 patients were included in this study, with a median age of 36.0 (interquartile range (IQR) 32.0-46.0) years and median HRT duration of 2.0 (IQR 1.0-6.0) years. Multivariable linear regressions revealed no significant predictors for central forehead length. However, lateral forehead length was positively predicted by age (B=0.06, 95% confidence interval (CI) [0.03-0.08], p < 0.001) and hair treatment (B=0.66, 95% CI [0.14-1.18], p = 0.01), but negatively predicted by HRT duration (B=-0.07, 95% CI [-0.10 to -0.04], p < 0.001). CONCLUSIONS: Although older age is a predictor of lateral hairline recession in TGNB AMAB individuals, lateral forehead length was also predicted to decrease by 0.07 cm with each year of feminizing hormone therapy in patients over 30 years of age.

Virtual Modeling in Gender-Affirming Facial Masculinization Surgery.

SUMMARY: The increase in access to facial gender-affirming surgery has resulted in a rise in facial feminization surgeries for transfeminine and gender non-binary populations. However, refined execution of facial masculinization is challenged by the lack of defined measurements for facial augmentation, the lack of long-term predictability in autologous bone grafting in augmentation procedures, and the lack of precision in traditional facial augmentation procedures with generic alloplastic implants. In this work, we describe an innovation in facial masculinization surgery using modern reconstructive craniofacial surgical techniques with preoperative virtual modeling and the fabrication of three-dimensionally printed, patient-specific custom implants.

Correlating Material Properties to Osteoprotegerin Expression on Nanoparticulate Mineralized Collagen Glycosaminoglycan Scaffolds.

Precision material design directed by cell biological processes represents a frontier in developing clinically translatable regenerative technologies. While understanding cell-material interactions on multipotent progenitor cells yields insights on target tissue differentiation, equally if not more important is the quantification of indirect multicellular interactions. In this work, the relationship of two material properties, phosphate content and stiffness, of a nanoparticulate mineralized collagen glycosaminoglycan scaffold (MC-GAG) in the expression of an endogenous anti-osteoclastogenic secreted protein, osteoprotegerin (OPG) by primary human mesenchymal stem cells (hMSCs) is evaluated. The phosphate content of MC-GAG requires the type III sodium phosphate symporter PiT-1/SLC20A1 for OPG expression, correlating with ß-catenin downregulation, but is independent of the effects of phosphate ion on osteogenic differentiation. Using three stiffness MC-GAG variants that do not differ significantly by osteogenic differentiation, it is observed that the softest material elicited ≈1.6-2 times higher OPG expression than the stiffer materials. Knockdown of the mechanosensitive signaling axis of YAP, TAZ, ß-catenin and combinations thereof in hMSCs on MC-GAG demonstrates that ß-catenin downregulation increases OPG expression by 1.5-fold. Taken together, these data constitute a roadmap for material properties that can used to suppress osteoclast activation via osteoprotegerin expression separately from the anabolic processes of osteogenesis.

Medicaid coverage for gender-affirming surgery: A state-by-state review.

OBJECTIVE: To systematically review Medicaid policies state-by-state for gender-affirming surgery coverage. DATA SOURCES AND STUDY SETTING: Primary data were collected for each US state utilizing the LexisNexis legal database, state legislature publications, and Medicaid manuals. STUDY DESIGN: A cross-sectional study evaluating Medicaid coverage for numerous gender-affirming surgeries. DATA COLLECTION/EXTRACTION METHODS: We previously reported on state health policies that protect gender-affirming care under Medicaid coverage. Building upon our prior work, we systematically assessed the 27 states with protective policies to determine coverage for each type of gender-affirming surgery. We analyzed Medicaid coverage for gender-affirming surgeries in four domains: chest, genital, craniofacial and neck reconstruction, and miscellaneous procedures. Medicaid coverage for each type of surgery was categorized as explicitly covered, explicitly noncovered, or not described. PRINCIPAL FINDINGS: Among the 27 states with protective Medicaid policies, 17 states (63.0%) provided explicit coverage for at least one gender-affirming chest procedure and at least one gender-affirming genital procedure, while only eight states (29.6%) provided explicit coverage for at least one craniofacial and neck procedure (p = 0.04). Coverage for specific surgical procedures within these three anatomical domains varied. The most common explicitly covered procedures were breast reduction/mastectomy and hysterectomy (n = 17, 63.0%). The most common explicitly noncovered surgery was reversal surgery (n = 12, 44.4%). Several states did not describe the specific surgical procedures covered; thus, final coverage rates are indeterminate. CONCLUSIONS: In 2022, 52.9% of states had health policies that protected gender-affirming care under Medicaid; however, coverage for various gender-affirming surgical procedures remains both variable and occasionally unspecified. When specified, craniofacial and neck reconstruction is the least covered anatomical area compared with chest and genital reconstruction.

Feminization of the Forehead: A Scoping Literature Review and Cohort Study of Transfeminine Patients.

BACKGROUND: Facial feminization may be performed to alleviate gender dysphoria among transfeminine patients. The upper third of the face has several characteristics, including hairline shape and position, brow position, and forehead protrusion, that may confer feminine identity. The purpose of this study is to conduct a scoping literature review of techniques performed for forehead feminization and to additionally study clinical outcomes within an institutional cohort. METHODS: A systematic literature review was conducted to review articles that discussed techniques and clinical outcomes associated with procedures performed for feminization of the upper third of the face. A retrospective review of patients undergoing such procedures by the senior author was then conducted. Variables collected included demographic factors, operative details, and postoperative outcomes such as complications, revisions, and re-operations. RESULTS: Initial review yielded sixty-seven articles. Title and abstract review followed by standardized application of inclusion and exclusion criteria resulted in a total of twenty-two studies for analysis. Priorities of forehead feminization entail frontal bossing reduction, frontonasal angle widening, orbital contouring, brow lifting, and hairline advancement. Eighty-five patients were included for analysis. The majority were of Caucasian race (56%) and had type 3 forehead classification (92%). The average planned setback of the anterior table was 4.12 mm. CONCLUSIONS: The core tenets of the feminization of the forehead lie in the overall creation of a harmonic curvature of the forehead with other facial features. Our multi-pronged analysis presents an updated review of these principles, which may help plastic surgeons in performing procedures to feminize the upper third of the face.

Ethnic variation in lower face anthropometry on facial computed tomography scans for patients seeking facial feminization surgery.

BACKGROUND: Facial feminization surgery (FFS) is the most common form of facial gender-affirming surgery. One of the current knowledge gaps is the understanding of differences among racial groups in baseline craniofacial norms for transgender and nonbinary patients. METHODS: All patients who sought consultation for FFS and underwent craniofacial computed tomography (CT) scans at a single institution between 2018 and 2023 were included. Patients who underwent previous facial surgeries were excluded. Chart reviews were conducted for patient characteristics, including race, age, hormone therapy duration, and prior gender-affirming surgeries. Racial categorizations included White, Latinx, African American, or Asian. Patients with other or multiracial identities were excluded. Lower face measurements were derived from preoperative facial CT scans. Comparative analyses were performed on all measurements among the racial groups. RESULTS: In this study, 204 patients were included with an average age of 32.0 ± 10.2 years and a median hormone therapy duration of 2.0 years. The notable differences among the racial groups were: 1. Zygomatic width was the largest in Asian patients (13.5 ± 0.6 cm) compared to all other racial groups (p = 0.03), 2. Nasolabial angle was the smallest in African American patients (82.5 ± 13.1 degrees, p < 0.001), 3. Lower face height was the largest in African American patients (6.9 ± 0.7 cm, p < 0.001), and 4. Lateral mandibular flare was the largest in African American patients (0.4 ± 0.1 cm) and the smallest in Latinx patients (0.2 ± 0.1 cm, p < 0.001). CONCLUSIONS: Specific target areas of FFS should be carefully considered to account for possible baseline ethnic differences. Relative facial proportions may also be a more salient surgical planning tool in transgender and gender nonbinary patients rather than absolute measurements alone.

Floating electrode-dielectric barrier discharge-based plasma promotes skin regeneration in a full-thickness skin defect mouse model.

Wound healing involves a complex and dynamic interplay among various cell types, cytokines, and growth factors. Macrophages and transforming growth factor-ß1 (TGF-ß1) play an essential role in different phases of wound healing. Cold atmospheric plasma has a wide range of applications in the treatment of chronic wounds. Hence, we aimed to investigate the safety and efficacy of a custom-made plasma device in a full-thickness skin defect mouse model. Here, we investigated the wound tissue on days 6 and 12 using histology, qPCR, and western blotting. During the inflammation phase of wound repair, macrophages play an important role in the onset and resolution of inflammation, showing decreased F4/80 on day 6 of plasma treatment and increased TGF-ß1 levels. The plasma-treated group showed better epidermal epithelialization, dermal fibrosis, collagen maturation, and reduced inflammation than the control group. Our findings revealed that floating electrode-dielectric barrier discharge (FE-DBD)-based atmospheric-pressure plasma promoted significantly faster wound healing in the plasma-treated group than that in the control group with untreated wounds. Hence, plasma treatment accelerated wound healing processes without noticeable side effects and suppressed pro-inflammatory genes, suggesting that FE-DBD-based plasma could be a potential therapeutic option for treating various wounds.
