Phalloplasty: A Review of Techniques and Outcomes

Imaging the acute complications of gender-affirming surgeries: a primer for radiologists in the emergency setting

Gender-affirming surgery (GAS) is increasingly being performed. GAS is tailored to the patient leading to a diverse spectrum of radiologic post-operative findings. Radiologists who are unfamiliar with expected anatomic alterations after GAS may misdiagnose important complications leading to adverse patient outcomes. This collaborative multi-institutional review aims to: Describe relevant embryology and native anatomy. Describe relevant Gender-Affirming Surgery (GAS) techniques and expected neo-anatomy with associated complications, including common terminology. Review expected imaging appearance of neo-anatomy/postoperative findings. Review multi-modality [ultrasound, plain film, retrograde urethrogram, computed tomography] emergent imaging findings. Understand unique patient evaluation and imaging protocol considerations in the GAS population. Discuss pearls and pitfalls of imaging in the acute post-GAS setting.

Sexual Function in Post-surgical Transgender and Gender Diverse Individuals

Surgical treatment for gender dysphoria consists of facial, chest, and genital surgery. Chest and genital gender affirmation surgeries alter the form and function of the native organs. This can have a profound impact on sexual function for transgender and gender- diverse individuals. In this article, the authors will discuss the impacts that chest and genital gender affirmation surgeries can have on sexual function.

Individualized care for patients with intersex (differences of sex development): Diagnosis and treatment of aphallia

This review discusses issues and concerns in the management of aphallia, updating status of a post-pubertal individual who required further surgery after having initial surgery for aphallia as an infant. Through this case, which discusses an 18-year-old young adult who had penile agenesis, who desired further phalloplasty involving glanuloplasty and implantation of an erectile device, we highlight the importance of periodic evaluation and close follow up. Surgery during infancy or early childhood to create a penis is important for gender development in a boy, especially if there were functional testes during fetal life, even if this surgery would only be the first stage. There is a strong probability of subsequent surgery after initial phalloplasty before puberty, even with the use of currently refined techniques. Here we discuss the changing techniques that document the ongoing, continued refinement of these procedures, highlighting that further outcome data are needed to identify ways to further optimize current techniques.

Trends in Gender-Affirming Surgeries in the United States from 2010 to 2021

Introduction:  In 2017, an estimated 1.6 million adults and 150,000 teenagers identified as transgender in the United States. With ever-changing legislative developments regarding health care benefits for this population and the increasing number of patients presenting for gender-affirming surgery (GAS), there is a scarcity of literature on the temporal trends within the past decade. The objective of this study was to examine the temporal trends of the utilization of GAS. Methods:  We conducted a cross-sectional study using TriNetX, a federated research network containing deidentified aggregate patient data. Using International Code of Disease (ICD) and Current Procedural Terminology (CPT) codes, we identified patients with a diagnosis of gender dysphoria who underwent GAS from 2010 to 2021. Basic demographic information and complications were analyzed. Complications of interest included site failure, infection, and systemic complications. Results:  We identified a total of 8,403 patients who underwent GAS between January 2010 and December 2021. The number of procedures per year increased nearly 500% between 2016 and 2021 from 421 procedures to 2,224 procedures. Our demographic results were consistent with previous survey-based studies. The average age of patients who underwent masculinizing surgeries was consistently younger than those who underwent feminizing surgeries. Most patients undergoing GAS were of white race. The overall complication rate was 4.7%. Conclusion:  In conclusion, our study reveals a significant and rapid rise in the utilization of GAS in the United States, with a fivefold increase in procedures between 2016 and 2021. The demographic characteristics and low complication rates observed highlight the evolving landscape of health care for transgender individuals and the need for ongoing assessment and support in this field.

The Most-Cited Publications in Gender-Affirming Surgery: A Cross-Sectional Bibliometric Analysis

Background: Gender-affirming surgery is becoming more common among reconstructive surgeons. Bibliometric analyses are statistical evaluations of published scientific correspondence and are a validated method of measuring influence in the scientific community. As no such bibliometric analysis has been done as of yet, the purpose of this study is to identify the characteristics of the 50 most-cited peer-reviewed articles on gender-affirming surgery. Methods: The Scopus abstract and citation database was utilized in April 2020 to search for English-language publications related to gender-affirming surgery. The 50 most-cited publications that met inclusion criteria were reviewed for various metric tabulations. Results: The 50 publications have been cited a total of 4402 times. Thirty-one (62%) were published in 2000 or later. Phalloplasty was the most discussed surgical technique, and 18 of the articles focused on female-to-male (FtM) patients. Case series (46%) and review articles (24%) were most common and there were no Level I or Level II studies. The Netherlands contributed the most, with 13 articles. Among the most frequent keywords in the 50 abstracts were "flap" and "complication". The earliest author keywords used were "transsexual" and "sex reassignment". Conclusions: The keyword usage in these abstracts over time seems to follow the trend of a more socially inclusive lexicon. A focus on studies with a higher level of evidence may optimize surgeon education and more appropriately guide clinical practice. This study reveals that the most influential and commonly referenced studies may not be sufficient to appropriately guide clinical practices.

Phalloplasty Flap Salvage Using a Superficial Circumflex Iliac Artery Perforator Propeller Flap

Background

Partial phalloplasty flap loss presents an evolving challenge, largely due to the complex demands required for both aesthetics and function. We describe our novel experience using the superficial circumflex iliac perforator (SCIP) propeller flap for neophallus salvage when skin grafting alone provides insufficient soft tissue bulk or coverage.

Methods

We retrospectively reviewed patients who underwent SCIP propeller flap reconstruction after phalloplasty partial flap loss. After suprafascial dissection, superficial circumflex iliac vessel perforator(s) were isolated toward the femoral origin. The flap was rotated 180 degrees and inset into the ventral or distal neophallus depending on the region of flap loss. If glans reconstruction was required, the flap was tubularized before inset. Division and inset were performed at a second stage, followed by subsequent glansplasty, urethral creation, and/or penile implant placement.

Results

SCIP propeller flap reconstruction was performed for four patients after one to six debridements at a mean of 6.5 (range 1.0-19.2) months following the initial phalloplasty. Three patients had lost the ventral phallus due to venous insufficiency, arterial insufficiency, and excessive postoperative swelling, respectively. The fourth patient experienced near-total loss of the glans following penile implant insertion. Division and inset was performed at an average of 7.5 (range 5.0-12.0) weeks after SCIP flap. There were no complications related to SCIP flap viability.

Conclusion

The SCIP propeller flap allows salvage of partial flap loss following phalloplasty by providing thin, pliable soft tissue bulk and skin coverage with minimal donor site morbidity, without the need for microsurgery, allowing progression with subsequent reconstructive stages.

[Choice of flaps for phalloplasty: what is the contemporary standard? Consensus Statement of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels]

The ever-expanding number of transmen as well as their surgeons share an increasing interest in the construction of a neophallus. While the indication for surgery and the positive effect of a phalloplasty on the quality of life, mental health and sexual function has already been thoroughly analysed, there is a lack of data comparing and evaluating the surgical steps. During the consensus conference on the "choice of flaps for phalloplasty" at the annual meeting of the German-Speaking Society for Microsurgery of Peripheral Nerves and Vessels, the current literature was discussed and a consensus on the surgical technique of a phalloplasty was reached. This manuscript publishes jointly developed recommendations on the following topics: choice of flaps for phalloplasty, preoperative diagnostic tests before phalloplasty, urethral construction in the radial forearm flap and anterior lateral thigh flap, preformation of the urethra at the forearm or thigh, venous drainage of the radial forearm flap, innervation of the phallus, staged phalloplasty, coronaplasty and managing the donor site of a radial forearm flap.

[Phalloplasty by radial forearm free flap in the context of female-to-male gender reassignment surgery]

AIMS

The aims of this article are to provide an overview of the technique of phalloplasty by radial forearm free flap in the context of female-to-male gender reassignment surgery, with a specific focus on surgical technical details and the prevention of postoperative complications.

METHODS

In the light of our 30 years of experience in caring for female-to-male transgender individuals and conducting a critical review of the literature, we exhaustively present our technique of radial forearm free flap phalloplasty in female-to-male gender reassignment surgery.

RESULTS

The technique of radial forearm free flap phalloplasty, utilizing a one-stage approach for neourethral and neophallus construction based on the "tube within a tube" principle, not only achieves an aesthetically pleasing appearance of the neophallus resembling a normal penis with tactile and erogenous sensitivities but also yields a functional neourethra and satisfactory penile rigidity using implants for standing voiding and sexual intercourse. This intricate surgical procedure demands not only meticulous execution of all surgical maneuvers but also high-level postoperative care. Despite refinements in technique over recent decades, aesthetic sequelae at the donor site of the flap remain subject to criticism, and postoperative complications, particularly of vascular and urological nature, remain significant.

CONCLUSION

Future optimization of the surgical technique for this procedure will be imperative to minimize postoperative complications and establish a true technical "gold standard" for phalloplasty in female-to-male transgender individuals.

[Genital gender affirming surgery in trans men]

OBJECTIVE

Genital surgery for masculinisation in the context of gender incongruence is characterised by the reconstruction of male genitalia using multiple surgical techniques - free flap phalloplasty, pedicled flap phalloplasty or metaoidioplasty - which this article aims to describe.

MATERIAL AND METHODS

A narrative review of the literature on these trans surgeries was carried out.

RESULTS

Each technique has specific advantages and disadvantages, and does not produce the same results in terms of surgical risks, size of the reconstructed phallus, sensitivity, sexual function and urinary function.

CONCLUSION

This surgical decision must therefore be shared with the person concerned, based on a clear understanding of their expectations and objectives. Long-term follow-up is recommended.

Modified Surgical Model for Genitourinary Vascularized Composite Allotransplantations: An Anatomical Study

SUMMARY

Total penile reconstruction represents a surgical challenge. Autologous reconstructions offer limited aesthetic results and variable urinary function recovery. To date, five genitourinary vascularized composite allotransplantations have been performed worldwide. However, in all cases, vascular complications have been reported. The objective of this study was to develop a modified surgical model for penile allotransplantation to limit the number of microsurgical anastomoses and ensure vascular reliability. The authors studied penile allotransplantation by performing dissections on 12 subjects. The study was carried out to ensure the vascularization of the entire penis shaft while limiting the number of anastomoses. The penis vasculature includes numerous angiosomes between its different subunits. The penile skin envelope is supplied by both external and internal pudendal vessels. The cavernous and spongy bodies are supplied by terminal branches of the internal pudendal vessels. The anterior pubic osteotomy approach allows access to the root of the cavernous bodies and to the Alcock ducts. This modified surgical model for penile allotransplantation could help future teams involved in genitourinary vascularized composite allotransplantations to improve urinary and sexual function.

CLINICAL RELEVANCE STATEMENT

The authors introduce an improved surgical technique for penile transplantation that enhances vascularization and graft viability. This innovative procedure optimizes blood flow through meticulous microsurgical anastomosis, resulting in improved functional outcomes. Its potential to revolutionize penile transplantation warrants further exploration and validation within the surgical community.

Deep inferior epigastric vessels for free scapular flap phalloplasty

We aimed to present our 20-year experience of using the deep inferior epigastric vessels as recipient vessels for free scapular flaps phalloplasty and evaluate the outcomes. Penile reconstruction was performed using a free scapular flap between 2000 and 2020 by the same surgical team. Deep inferior epigastric vessels were used in all the cases. The surgical techniques and outcomes were described. Overall, 73 patients used the deep inferior epigastric artery (DIEA) as the recipient artery. Regarding the recipient veins, 2 veins were anastomosed in 72 (98.6%) patients, 1 deep inferior epigastric vein (DIEV) was used in 1 patient, 2 DIEV in 14, 1 DIEV + superficial inferior epigastric vein (SIEV) in 13, 1 DIEV + superficial circumflex iliac vein (SCIV) in 38, great saphenous vein (GSV) + SCIV in 4, and GSV + SIEV in 3. The mean age and body mass index of the study cohort was 28 years and 24.3 kg/m2, respectively. The shortest follow-up time was 7 months. Eleven patients had flap-related complications. Three patients were readmitted to the operating room within 24 hours, and 2 of them underwent salvage procedures with venous revision. Two patients lost the entire flap. One patient with 3-cm distal portion necrosis required surgical intervention. Three patients experienced urethral necrosis. DIEA is a suitable receptor artery for inflow. The DIEV, SIEV, and SCIV are available options for venous drainage according to the patient anatomical characteristics. The GSV can be an excellent backup for outflow and salvage procedures.

Emergency Medicine Considerations in the Transgender Patient

Transgender patients are at high risk for poor health outcomes and many harbor fear of healthcare settings secondary to prior discrimination, perceived sensationalism, clinician unfamiliarity, and unwanted exams. It is essential to approach transgender patients without judgement and with empathy. Asking open ended questions with explanation as to why your questions are pertinent to their specific care will help create rapport and trust. Through a basic working knowledge of terminology, types of hormone therapy, non-surgical techniques, garments, and surgical procedures typically encountered by such patients, and their respective potential side effects and complications, clinicians can provide quality care to transgender patients.

Determining the outcomes of urethral construction in phalloplasty

OBJECTIVE

To evaluate the surgical and functional outcomes of urethral reconstruction associated with phalloplasty, depending on the surgical techniques and patient history.

MATERIALS AND METHODS

We conducted a single-centre retrospective study including 89 patients who underwent phalloplasty with urethral reconstruction between 2007 and 2018. Patients included were trans-male patients undergoing gender-affirming surgery and cis-male patients undergoing penile reconstruction after trauma, congenital malformation, or cancer. Urethral reconstructions were performed by free flap or skin graft (total or thin). Secondary urethroplasty may include direct vision urethrotomy, excision-anastomosis, or augmentation urethroplasty (skin graft, buccal mucosa graft). Patient demographics, medical history, peri- and postoperative data were collected from patient files. Functional results were evaluated using individual questionnaires.

RESULTS

The mean (±sd) follow-up duration was 5.5 (±3.7) years. No significant difference was found for total urethral complication rate (fistula and/or stricture) according to type of urethral construction (70.9% for free flap urethra vs 73.5% for skin graft urethra; P = 0.911), nor according to the patient's grounds for surgery (72.7% for cis-male vs 71.8% for trans-male patients; P = 1). A total of 36 patients (40.5%) answered the functional questionnaire, of whom 80.5% reported usually voiding while standing and 47.5% were comfortable with urinating in public.

CONCLUSIONS

Urethral construction in phalloplasty is associated with a high complication and revision rate regardless of the type of urethral reconstruction. Voiding in a standing position is generally possible but should not conceal feeble functional results.

Lessons learned from the first 15 years of penile transplantation and updates to the Baltimore Criteria

Since 2006, five penis transplants have been performed worldwide. Mixed outcomes have been reported, and two of the five penile transplants have required explantation. However, the long-term outcomes have been encouraging when compliance is implemented, whether standard induction and triple therapy maintenance, or single therapy maintenance. Follow-up monitoring of transplant recipients has enabled a synthesis of technical considerations for surgical success and has shown stable leukocyte counts and renal function after a donor bone-marrow-based immunomodulatory regimen followed by tacrolimus monotherapy as long as 3 years post-transplant, as well as continuous nerve regeneration of penile allografts 3 years post-transplant. Areas of uncertainty include the ethics of donor-recipient colour mismatch, surveillance for sexually transmitted infections and how to optimize patient compliance. Questions also remain with respect to the long-term immunological sequelae of penile tissue, functional outcomes, psychosocial implications and patient selection. Patient counselling should be modified to mention the possibility of long-term improvement in nerve regeneration and sufficient renal function with single-therapy maintenance, and to build a longitudinal dialogue and partnership between the patient and the multidisciplinary care team regarding the risks of sexually transmitted infection instead of surveillance.

Functional and surgical outcomes after phalloplasty in cis men

PURPOSE

Evaluate the surgical outcomes along with a comprehensive assessment of functional outcomes in cis men (non-trans) who underwent phalloplasty.

METHODS

All consecutive cis men who underwent phalloplasty from 2008 to 2018 for penile insufficiency due to various causes were included. These underwent phalloplasty by either a radial forearm free flap (RFFF) or suprapubic phalloplasty (SPP). Data were collected from medical files. A questionnaire was sent a minimum of 1 year after surgery to each patient to evaluate sexual function and self-esteem, satisfaction with genitals, and urinary function.

RESULTS

Among the 19 patients included, 12 underwent RFFF and 7 SPP; 25% of those who had RFF and 14.3% of those with SPP had a Clavien-Dindo ≥ 2 complication. A total of 16 patients had a urethroplasty procedure, 50.0% of whom had a Clavien-Dindo ≥ 2 complication. Penile prostheses were implanted in 14 patients; 64.3% of whom had a complication. Seven patients answered the questionnaire (36.8%); the relationship satisfaction score was 89.5/100 and the confidence score was 100/100. Among the 5 patients who had a sexual relationship, all reported having a lot of pleasure during sexual intercourse and reached orgasm at least "regularly". At least 66.7% of the patients were "satisfied" or "very satisfied" about the size and the appearance of genitals. Among the 5 patients who answered questions regarding urinary function, 60.0% had standing micturition, and 80.0% reported being comfortable in public toilets.

CONCLUSION

Despite the high frequency of complications and the need for revision surgery, phalloplasty seems to allow a satisfying psychosexual and urinary functions for cis men suffering from penile insufficiency.

Outcomes Following Gender Affirming Phalloplasty: A Systematic Review and Meta-Analysis

INTRODUCTION

Phalloplasty is one of the genital genders affirming surgeries sought by transmasculine transgender patients during transition. Despite current advances in surgical techniques, the lack of consistency in outcomes evaluation for phalloplasty leads to significant challenges in guiding patients in clinical decision making.

AIMS

This systematic review and meta-analysis aims to assess outcomes for different phalloplasty surgical techniques.

METHODS

The literature was searched using Medical Literature Analysis and Retrieval System Online (MEDLINE; PubMed), Excerpta Medica database, and Cochrane Database of Systematic Reviews. All English-language randomized control trials, prospective and retrospective cohort studies, case series, and case reports of at least 4 patients were included. The primary outcome was postoperative complications, and the secondary outcomes were functional and aesthetic results. Proportional meta-analysis was used to pool complication rates using a random-effects model.

RESULTS

Database searching generated 39 final articles, with 19 case series, 3 cross-sectional studies, and 17 retrospective cohort studies. A total of 1731 patients underwent phalloplasty, with the most common type of reconstruction performed being the radial forearm free flap (75.1%). Overall complication rate was high at 76.5%, of which urethral complications were high in all reconstructive subgroups (urethral fistula rate of 34.1% and urethral stricture rate of 25.4%). Postoperative functional outcomes were reported in 57.6% of patients, finding that most had tactile sensation (93.9%) and can void while standing (92.2%). Aesthetic outcomes were only reported in 6.3% of patients, with mean length achieved being 12.26 cm (SD = 0.81 cm) and mean circumference being 10.18 cm (SD = 3.69 cm).

CONCLUSION

In the transmasculine transgender population, current evidence of the various phalloplasty surgical techniques and their expected postoperative outcomes is weak. Future research may consider developing a standardized core outcome set to improve clinical decision making. Wang AMQ, Tsang V, Mankowski P, et al. Outcomes Following Gender Affirming Phalloplasty: A Systematic Review and Meta-Analysis. Sex Med Rev 2022;10:499-512.

A Novel Technique of Urethroplasty Could Reduce Urethra-Related Complications in Phalloplasty With Urethral Lengthening

INTRODUCTION

Urethral lengthening in phalloplasty could bring many postoperative complications, such as urethra fistula and stricture, which greatly affects the patient's mental health and quality of life.

AIM

To describe a novel technique of vaginal mucosal graft for prelamination urethra (VMGPU) combined with modified urethral anastomosis (MUA) for the reconstruction of a neourethra.

METHODS

A retrospective study of transgender men between January 2006 and March 2021 was conducted. Patients were divided into three groups according to the surgical methods : traditional group（TG，VMGPU group（VG） and VMGPU+MUA group (VMG).

MAIN OUTCOME MEASURE

The main outcomes measures were demographics, surgical characteristics, complications, International Prostate Symptom Score（IPSS，Quality of Life（QOL） score，and voiding frequency conditions.

RESULTS

Of 80 eligible transgender men（TG:n = 39，VG:n = 31, VMG:n = 10), the urethral fistula developed in 19/39 (49%) patients in TG, 8/31 (26%) in VG, and 1/10 (10%) in VMG (P = 0.034). The urethral stricture formed in 15/39 (38%) patients in TG, 4/31 (13%) in VG, and 1/10 (10%) in VMG (P = 0.028). Compared with TG, the VG got more favorable IPSS. The QOL scores showed that patients in VG or VMG were more satisfied with their postoperative status.

CLINICAL IMPLICATIONS

VMGPU combined with MUA may help reduce urethral complications for transgender men who wish to undergo phalloplasty with urethral lengthening.

STRENGTH & LIMITATIONS

VMGPU combined with MUA focuses on reducing the urethra-related complications in the anastomotic stoma between the fixed and the penile urethra, which has not been noticed in the past. The limitations of this study are that the retrospective study design is prone to bias; the study using VMGPU+MUA technique is only in the preliminary stage, and more cases are needed to prove its effectiveness; the median follow-up in VMG was only 2 years, and longer-term follow-up results are inconclusive; the IPSS, QOL, and the voiding frequency chart were not validated in transgender men.

CONCLUSION

Our pilot study suggests that VMGPU combined with MUA may reduce the urethra-related complications, especially the urethral fistula in the anastomosis stoma between the fixed and the penile urethra.

Standards of Care for the Health of Transgender and Gender Diverse People, Version 8

Background: Transgender healthcare is a rapidly evolving interdisciplinary field. In the last decade, there has been an unprecedented increase in the number and visibility of transgender and gender diverse (TGD) people seeking support and gender-affirming medical treatment in parallel with a significant rise in the scientific literature in this area. The World Professional Association for Transgender Health (WPATH) is an international, multidisciplinary, professional association whose mission is to promote evidence-based care, education, research, public policy, and respect in transgender health. One of the main functions of WPATH is to promote the highest standards of health care for TGD people through the Standards of Care (SOC). The SOC was initially developed in 1979 and the last version (SOC-7) was published in 2012. In view of the increasing scientific evidence, WPATH commissioned a new version of the Standards of Care, the SOC-8. Aim: The overall goal of SOC-8 is to provide health care professionals (HCPs) with clinical guidance to assist TGD people in accessing safe and effective pathways to achieving lasting personal comfort with their gendered selves with the aim of optimizing their overall physical health, psychological well-being, and self-fulfillment. Methods: The SOC-8 is based on the best available science and expert professional consensus in transgender health. International professionals and stakeholders were selected to serve on the SOC-8 committee. Recommendation statements were developed based on data derived from independent systematic literature reviews, where available, background reviews and expert opinions. Grading of recommendations was based on the available evidence supporting interventions, a discussion of risks and harms, as well as the feasibility and acceptability within different contexts and country settings. Results: A total of 18 chapters were developed as part of the SOC-8. They contain recommendations for health care professionals who provide care and treatment for TGD people. Each of the recommendations is followed by explanatory text with relevant references. General areas related to transgender health are covered in the chapters Terminology, Global Applicability, Population Estimates, and Education. The chapters developed for the diverse population of TGD people include Assessment of Adults, Adolescents, Children, Nonbinary, Eunuchs, and Intersex Individuals, and people living in Institutional Environments. Finally, the chapters related to gender-affirming treatment are Hormone Therapy, Surgery and Postoperative Care, Voice and Communication, Primary Care, Reproductive Health, Sexual Health, and Mental Health. Conclusions: The SOC-8 guidelines are intended to be flexible to meet the diverse health care needs of TGD people globally. While adaptable, they offer standards for promoting optimal health care and guidance for the treatment of people experiencing gender incongruence. As in all previous versions of the SOC, the criteria set forth in this document for gender-affirming medical interventions are clinical guidelines; individual health care professionals and programs may modify these in consultation with the TGD person.

Genital Reconstruction following Fournier's Gangrene

INTRODUCTION

Fournier's gangrene is a urological emergency, comprising of type I necrotizing fasciitis resulting in anatomic defects affecting the perineum, perianal region, and external genitalia in both men and women, often requiring reconstruction.

OBJECTIVES

The aim of this article is to provide a comprehensive review of the different reconstructive techniques for Fournier's gangrene.

METHODS

A literature search was performed on PubMed with the search terms "Fournier"s gangrene" "genital reconstruction" and "Fournier's gangrene phalloplasty." The European Association of Urology's guidelines on Urological infections were also consulted for recommendations.

RESULTS

Reconstructive procedures include primary closure, scrotal advancement flaps, fasciocutaneous flaps, myocutaneous flaps, skin grafts, and phalloplasty. There is insufficient evidence to support that flaps lead to better outcomes than skin grafts, or vice versa, particularly for scrotal defects. Both techniques have been shown to have satisfactory aesthetic results, with good skin color match and natural scrotal contour. With regards to phalloplasty, there is a lack of data specifically relating to Fournier's gangrene, as most articles were addressed toward gender affirmation surgery. Furthermore, there is a lack of guidelines in both the immediate and reconstructive management of Fournier's gangrene. Lastly, the outcomes reported following reconstructive surgery have been objective rather than subjective, meaning that patient satisfaction was rarely recorded.

CONCLUSION

Further research is required in the field of reconstructive surgery specific to Fournier's gangrene, which should also take into consideration patient demographics and subjective reports regarding cosmesis and sexual function.

A Comparative Study of Urinary Complication Rates before and after the Incorporation of a Urethral Lengthening Technique during Masculinizing Genital Gender Affirmation Surgery

Objectives  Masculinizing genital gender affirmation surgery (MgGAS) consists of operative procedures designed to help the transition of transmen in their journey toward male gender role. Phalloplasty and urethral lengthening remain the most challenging of these surgeries, as the female urethra (4 cm long) must be lengthened to male dimensions (15–29 cm) with anastomosis at two sites, the native urethra/pars fixa urethra and the pars fixa urethra-penile urethra. As a result, there is a high incidence of urinary complications such as strictures and fistulae. Authors incorporated a urethral lengthening technique to reduce urinary complications in MgGAS. They compare the rates of urinary complications rates in cohorts before and after the introduction of this technique.

Materials and Methods  Authors have been performing phalloplasty since past 27 years, utilizing mainly free radial artery forearm flap (fRAFFp 431 cases) and pedicled anterolateral thigh flap (pALTp 120 cases). A retrospective review and comparison of urinary complications were performed before and after the introduction of their new technique since March 2017.

Results  There was a statistically significant reduction in the incidence of stricture with and without fistulae (25.94% with conventional and 4.17% with urethral lengthening technique p  = 0.001) and fistulae alone (12.81% with conventional and 2.78% with urethral lengthening technique p  = 0.011) in fRAFFp cases. In pALTp cases, the respective reductions were 43.08 to 17.07%, p  = 0.006 (significant), and 13.85 to 4.88%, p  = 0.197 (not statistically significant).

Conclusion  Over years, the rates of urinary complications in MgGAS have remained constant, varying from 25 to 58% for strictures and 17 to 75% for fistulae as noted by many authors. Authors noted that in most of their cases, strictures occurred at distal pars fixa urethra (DPFU)-penile urethra anastomosis and incorporated a urethral lengthening technique, which lengthens the DPFU by 3 to 5 cm at this anastomotic site, thus significantly reducing the anastomotic tension and the rate of urinary complications.

Primary Use of the Deep Inferior Epigastric Pedicle for Free-flap Phalloplasty: Rationale, Technique, and Outcomes

Most free-flap phalloplasty reports describe the femoral artery and great saphenous vein as recipient vessels, with the deep inferior epigastric artery and venae comitantes (DIEA/V) only rarely reported. We review our experience with preferentially using the DIEA/V as recipient vessels in gender-affirming free-flap phalloplasty, with DIEV as primary venous outflow.

Gender-Affirming Surgeries: A National Surgical Quality Improvement Project Database Analyzing Demographics, Trends, and Outcomes

BACKGROUND

Gender affirmation surgery is an exponentially growing field within plastic surgery. The aim of our study is to analyze demographics, procedure type, trends, and outcomes in the surgical management of gender identity disorder in the past few years.

METHODS

The American College of Surgeons NSQIP database was queried for the years 2015 to 2019. International Classification of Diseases codes were used to identify all gender-affirming cases. Patients were categorized by procedure type using Current Procedural Terminology codes for feminizing/masculinizing top, bottom and head/neck procedures. Patient demographics, comorbidities, and postoperative complications were analyzed using SPSS statistics software. A comparative analysis was performed among the procedure type.

RESULTS

From 2015 to 2019, 4114 patients underwent a gender-affirming surgery (GAS) increasing the number of surgeries by over 400%, according to the NSQIP database. Demographics include age (mean = 32 years), body mass index (mean = 28 kg/m2), race (60% White, 22% unknown, 13% African American, 4% Asian, 1% other). Female to male procedures represented the most commonly performed (n = 2647; 64%), followed by male to female (n = 1278; 31%) with head/neck procedures representing 5% (n = 189) of all procedures. Top surgeries were also the most common (n = 2347, 57%), followed by bottom surgeries (n = 1578, 38%). The overall complication rate was 6% (n = 247), 2.1% (n = 4) for head/neck procedures, 8% (n = 134) for bottom procedures, and 3.5% (n = 84) for top surgeries.A reoperation within 30 days and related to the initial GAS occurred for 52 patients. Postoperative complication rates were statistically different between bottom surgeries compared with the top and head/neck procedure groups (P < 0.001). Increasing age and body mass index showed a significantly higher odds of having a complication.

CONCLUSIONS

Gender-affirming procedures have significantly increased over the past 5 years. Increased exposure through literature and research, as well as an improvement in social climates, including increasing insurance coverage have contributed to the expansion of these procedures. Low serious complication rates within 30 days prove GAS to be safe.

Significance and Surgical Options for Nontranssexual Phalloplasty: A Retrospective Single-Center Analysis of 166 Patients

OBJECTIVE

This study aimed to evaluate the long-term outcomes of phalloplasty and explore the clinical significance and selection of methods for penile reconstruction.

METHODS

The same surgical team performed primary phalloplasty in 166 nontranssexual patients using different surgical approaches between September 2000 and September 2020. All patients had at least 6 months of follow-up. Surgical techniques, complications, and outcomes were retrospectively recorded.

RESULTS

A total of 166 patients with indications such as penile trauma (n = 68 [41%]), amputation injury (n = 15 [9%]), iatrogenic (n = 13 [8%]), penile aplasia (n = 54 [32%]), genital ambiguity (n = 15 [9%]), and Peyronie disease (n = 1 [0.6%]) underwent different techniques of phalloplasty. Four patients (2.4%) had total flap necrosis, and 17 (10%) had partial flap necrosis. The total urethral complications rate was 32.5% (54 of 166); however, all the patients were able to void while standing after successful corrective surgery.

CONCLUSIONS

Individualized selection of appropriate penile reconstruction methods tailored to the cause of penile defect, patients' personal needs, thickness of donor site, and the blood supply of the flap are conducive to achieving satisfactory treatment results, reducing complications, and improving patient satisfaction. We believe that a scapular flap has certain advantages in nontranssexual patients, whereas other flaps also have their own indications.

Complications of free-flap procedures for phalloplasty in female-to-male transgender surgery: 25-year experience a single medical center

BACKGROUND

To present the complications of free-flap phalloplasty in three-staged female-to-male transgender surgery.

METHODS

This retrospective study included patients who underwent a three-staged free-flap phalloplasty for female-to-male transgender surgery between January 1988 and December 2013. Data regarding demographics, operative techniques, and complications were collected and analyzed.

RESULTS

A total of 101 patients with a mean age of 30.2 years were included. Phalloplasty with traditional free forearm tube-in-tube fasciocutaneous flap was performed in 25 (24.8%) patients, free forearm fasciocutaneous flap with vaginal mucosa for a prefabricated urethra in 30 (29.7%) patients, free radial forearm osteocutaneous flap with vaginal mucosa for a prefabricated urethra in 22 (21.8%) patients, and free fibula osteocutaneous flap with vaginal mucosa for a prefabricated urethra in 24 (23.8%) patients. Complication rates of partial flap loss, urethrocutaneous fistula, urethral stricture, and hair or stone formation were 12.9%, 49.5%, 24.8%, and 5.0%, respectively. Patients receiving fibula osteocutaneous flap phalloplasty had the lowest overall complication rate (33.3%), followed by those with radial forearm osteocutaneous flap (40.9%), forearm fasciocutaneous flap (43.3%), and forearm tube-in-tube fasciocutaneous flap (80.0%). Forearm tube-in-tube fasciocutaneous flap procedure was associated with significantly higher rates of overall complications (p = 0.05), urethrocutaneous fistula (p = 0.005), and hair or stone formation (p = 0.002) compared with the other three types of procedures. Rates of all complications did not significantly differ among fibula osteocutaneous flap, radial forearm osteocutaneous flap, and forearm fasciocutaneous flap procedures.

CONCLUSION

In free-flap phalloplasty for female-to-male transgender surgery, utilization of free fibula osteocutaneous flap with vaginal mucosa for a prefabricated urethra resulted in the lowest complication rate. Further comparisons among different procedures of phalloplasty are warranted.

Urethra Reconstruction and Revision Urethroplasty in Pedicled Anterolateral Thigh Flap Penile Reconstruction

OBJECTIVE

Neophallic urethroplasty remains a significant challenge in penile reconstruction. Currently, there is no ideal recognized method. Through this article, we aimed to share our experiences of urethral reconstruction in the pedicled anterolateral thigh flap penile reconstruction using modified techniques and alternative flaps.

METHODS

In this single-center study from 2010 to 2020, 49 patients underwent penile reconstruction with a pedicled anterolateral thigh flap; 17 patients had a micropenis, 3 had iatrogenic defects, and 29 had penile defects after trauma. Different urethroplasty methods, complications, and revision methods were separately described. The tube-in-tube technique was used in 6 cases; the superficial iliac circumflex artery perforator (SCIAP) flap and pudendal-thigh flap were used in 26 and 11 cases, respectively, and the pedicled scrotal flap was used in 6 cases. Revision urethroplasty due to postoperative necrosis (n = 3), stricture (n = 8), and fistula (n = 2) were performed in 13 cases.

RESULTS

The urethral complications (flap necrosis, urinary fistula, and stricture) were as follows: tube-in-tube, 66.7%; SCIAP flap, 46.2%; pudendal-thigh flap, 38.5%; and scrotal septum flap, 50%. After revision procedures, all patients could urinate while standing.

CONCLUSIONS

The characteristics and requirements of patients should be considered before designing a surgical plan. The tube-in-tube technique is the first choice for reconstructing the penis and urethra in a single stage for thinner patients. For other patients, a different flap can be used as a substitute for urethral reconstruction. The SCIAP, pudendal-thigh, and pedicled scrotal flaps can be used to reconstruct the urethra. The tubed SCIAP flap and pudendal-thigh flap are reliable, simple, and suitable for revision urethroplasty.

Autologous rib cartilage as implanted stiffener of phalloplasty: comparing three different methods

BACKGROUND

Maintaining the length, rigidity, and appearance of a reconstructed phallus in the long term has been challenging for phalloplasty and may depend on choosing the optimal implanted stiffener. The aim of this study was to determine the best type of stiffener for a reconstructed phallus regarding aesthetic and functional parameters.

METHODS

From 1987 to 2018, 376 individuals underwent phalloplasty at a single institution of which 81 met the following inclusion criteria: biological male gender, age between 18 and 60 years, radial forearm flap for tube-within-a-tube phalloplasty with rib cartilage and secondary glans sculpting and unimpaired urination preoperatively. Those were divided into three groups with regard to different types of autologous rib cartilage stiffener. A group with a cartilage strip, T-shaped cartilage, and mushroom-shaped cartilage group were evaluated regarding preserved length and aesthetic features of the phallus during a minimum period of 12 months. The rib cartilage length in the phallus was 10.5 cm in all groups.

RESULTS

The length of the phallus was 10.8 ± 0.5 cm in the cartilage strip group, 11.3 ± 0.3 cm in the T-shaped cartilage group and 11.3 ± 0.3 cm in the mushroom-shaped cartilage group at 1-year postoperatively. The aesthetic appearance score of mushroom-shaped cartilage group was 1.67 ± 0.48, significantly higher than the cartilage strip group (1.38 ± 0.50, p = 0.03) at 1 year after surgery.

CONCLUSIONS

The mushroom-shaped autologous rib cartilage group showed superior length preservation and aesthetic appearance and appeared as the best type of stiffener for one-phase phalloplasty.

Vascularized composite allotransplantation of the penis: current status and future perspectives

Given the multifunctional role of the penis in daily life, penile loss can be a physically and emotionally devastating injury. Options to restore penile loss have traditionally relied on autogenous free flap, local flaps, and skin grafts. These techniques provide satisfactory outcomes but carry high rates of urologic and prosthesis-related complications. Vascularized composite allotransplantation may offer a novel solution for these patients through reconstruction with true penile tissue. Still, penile transplants pose ethical, logistical, and psychosocial challenges. These obstacles are made more complex by the limited cases detailed in published literature. A review of the literature was conducted to assay current practices for penile reconstruction. Most modern complex penile reconstructions utilize autogenous pedicled or free tissue flaps, which may be harvested from a variety of donor sites. A total of five penile transplants have been described in the literature. Of these, four report satisfactory outcomes. The advent of genital allotransplantation has recently broadened the landscape of treatment for penile loss. Reconstruction using true penile tissue through vascularized penile allotransplantation has the possibility to engender increased penile function, sensation, and overall quality of life.

Defining Aesthetic Preferences for the Penis: A Photogrammetric and Crowdsourcing Analysis

BACKGROUND

Achieving an aesthetic phalloplasty result is important for patients with acquired or congenital defects of the penis, or with genital-related dysphoria. However, aside from length and girth, the aesthetic proportions of the male penis have not been defined.

OBJECTIVES

This study aimed to determine proportions of the male penis through photogrammetric analysis of nude male photographs and to verify these proportions with a crowdsourcing-based survey.

METHODS

Nude male photographs (n = 283) were analyzed to define aesthetic proportions of the male penis. Photographs were analyzed for the position of the penis on the torso in relation to the umbilicus and for the ratio of the dorsal and ventral glans of the penis in relation to the entire shaft length. Proportions were then further studied by crowdsourcing 1026 respondents with Amazon mechanical Turk.

RESULTS

The ideal position of the penis below the umbilicus is about 55% (6/11th) of the distance from the jugular notch to the umbilicus (measured average, 53.6%; survey-weighted average, 58.9%). The dorsal glans of the penis is about 33% (1/3rd) of the length of the entire shaft (measured average, 32.1%; survey-weighted average, 37.5%). The ventral glans of the penis is about 12.5% (1/8th) of the length of the entire shaft (measured average, 12.6%; survey-weighted average, 11.7%).

CONCLUSIONS

Measured proportions of the human penis follow exact fractions. Crowdsourcing data helped support photogrammetric analysis, with survey-preferred ratios within 5% of measured ratios. With further validation, these data can aid surgeons performing phalloplasty.

Salvage of a Near-Total Penile Amputation following Urinary Fistulization and Carbapenemase-Producing Klebsiella pneumoniae Infection with a Composite ALT Flap and Vascularized Fascia Lata

Reconstruction of complex penile defects is always challenging, as some defects are not possible to reconstruct with skin or mucosa grafts, and even local flaps may be precluded in complex wounds. We present a case of a 63-year-old otherwise healthy man, who underwent transurethral resection of the prostate for benign prostatic hyperplasia. After the procedure, he developed panurethral necrosis with consequent stricture. Three urethroplasties for reconstruction of the bulbar and distal urethra using buccal mucosa grafts, a preputial flap, and penile skin were performed by urology team in different institutions, but serious urinary fistulization and carbapenemase-producing Klebsiella pneumoniae (KPC) infection translated in a chronic wound, urethra necrosis, and near-total penile amputation. A composite anterolateral thigh flap and vascularized fascia lata were used with success together with a perineal urethroplasty in different stages, improving the ischemic wound condition. The extended segment of fascia lata was used for Buck's fascia replacement and circumferential reinforcement to cover the erectile bodies of the penis. The postoperative period was uneventful and after 12 months, there were no signs of recurrence or wound dehiscence. He was able and easily adapted to void in a seated position through the perineal urethrostomy that was made. To the best of our knowledge, this procedure has not been reported previously as a salvage procedure in a fistulizated and KPC infected penis, but it may be considered to avoid penile amputation in chronic infected and intractable wounds.

Transgender Scrotoplasty and Perineal Reconstruction With Labia Majora Flaps: Technique and Outcomes From 147 Consecutive Cases

PURPOSE

Labia majora, the embryologic homologs of the scrotum, are ideal donor tissue for transgender scrotoplasty. The technique is detailed, and surgical outcomes are assessed for scrotoplasty using labia majora rotational advancement flaps.

METHODS

We retrospectively reviewed the outcomes of phalloplasty patients who underwent either primary or secondary labia majora flap scrotoplasty and perineal reconstruction from October 1, 2017, to December 1, 2019. Bilateral elevation and rotational flap advancement from the posterior to anterior position formed a pouch-like scrotum. Perineal reconstruction involved multilayered closure with apposition of the inner thigh skin.

RESULTS

The mean follow-up was 12.5 months (0.5-26 months). One hundred forty-seven scrotoplasties were performed. Of the 147 total scrotoplasty patients, 133 had labia majora flap scrotoplasty and perineal reconstruction with single-stage phalloplasty. Distal flap necrosis occurred in 6 patients (4.1%); 5 were ipsilateral to the groin dissection required for phalloplasty. Large (>1 cm diameter) perineoscrotal junction dehiscence occurred in 7 patients (4.7%). All wounds were managed conservatively except for 3 patients who developed urethrocutaneous fistulas at the perineoscrotal junction. All 3 patients required fistula repair. Two (1.4%) scrotal hematomas and 3 (2.0%) perineal hematomas were seen; all required operative intervention.

CONCLUSIONS

Labia majora flap scrotoplasty via the bilateral rotational advancement technique and perineal reconstruction can be safely performed during phalloplasty. Minor wound complications are common and frequently heal with conservative management. Wounds that do not heal may be associated with urethral complications. Hematomas are rare but usually require operative intervention.

Treatment of Urethral Strictures in Transmasculine Patients

Background: Urethral strictures are a common complication after genital gender-affirming surgery (GGAS) in transmasculine patients. Studies that specifically focus on the management of urethral strictures are scarce. The aim of this systematic review is to collect all available evidence on the management of urethral strictures in transmasculine patients who underwent urethral lengthening. Methods: We performed a systematic review of the management of urethral strictures in transmasculine patients after phalloplasty or metoidioplasty (PROSPERO, CRD42021215811) with literature from PubMed, Embase, Web of Science and Cochrane. Preferred Reporting Items for Systematic reviews and Meta-Analysis-(PRISMA) guidelines were followed, and risk of bias was assessed for every individual study using the 5-criterion quality appraisal checklist. Results: Eight case series were included with a total of 179 transmasculine patients. Only one study discussed the management of urethral strictures after metoidioplasty. Urethral strictures were most often seen at the anastomosis between the fixed and pendulous urethra. For each stricture location, different techniques have been reported. All studies were at a high risk of bias. The current evidence is insufficient to favor one technique over another. Conclusions: Different techniques have been described for the different clinical scenarios of urethral stricture disease after GGAS. In the absence of comparative studies, however, it is impossible to advocate for one technique over another. This calls for additional research, ideally well-designed prospective randomized controlled trials (RCTs), focusing on both surgical and functional outcome parameters.

Masculinizing gender-affirming surgery for trans men and non-binary individuals: what you should know

Gender dysphoria, the discordance between one's gender identity and anatomy, affects nearly 25 million people worldwide, and the prevalence of transgender and non-binary identities is increasing because of greater acceptance and awareness. Because of the improved accessibility to gender-affirming surgery (GAS), many providers will care for patients during and after gender transition. For trans men (female-to-male), GAS represents a combination of procedures rather than a single surgery. The particular combination of masculinizing procedures is chosen on the basis of informed patient-provider discussions regarding the patient's goals and anatomy and implemented through a multidisciplinary team approach. In this review, we describe the common procedures comprising masculinizing GAS to improve delivery of specialized care for this patient population.

Gender-Affirming Surgeries in Transgender and Gender Diverse Adolescent and Young Adults: A Pediatric and Adolescent Gynecology Primer

Transgender and gender diverse adolescent and young adults (AYA) may seek gender-affirming surgeries (GAS) as part of their gender affirmation. A number of GAS are related to reproductive and sexual health, and pediatric and adolescent gynecology (PAG) clinicians are well positioned as sexual and reproductive health experts to provide care in this area. PAG clinicians may encounter patients presenting for preoperative counseling (including discussions regarding fertility, family building, future sexual function, and choice of oophorectomy at time of hysterectomy), requesting referrals to GAS clinicians, or requiring GAS aftercare, or those seeking general sexual and reproductive health care who have a history of GAS. This article reviews presurgical considerations for AYA seeking GAS, types of GAS, their impact on pelvic, sexual, and reproductive health, and aftercare that may involve PAG providers, with the goal of helping PAG clinicians to better understand these procedures and to empower them to engage collaboratively with GAS teams. With this knowledge, reproductive health clinicians can have an integral role as skilled collaborators in the world of AYA GAS in partnership with GAS surgeons.

Flap Selection Algorithm Based on the Body Mass Index for Phalloplasty in Female-to-Male Transgender: Techniques and Outcomes

Background Various phalloplasty methods have been reported; however, a consensus has not been reached. Therefore, we suggest an alternative algorithm for an ideal phalloplasty considering the factors that affect flap selection.

Methods We retrospectively examined 32 phalloplasty cases of female-to-male transgender. Flaps used for phalloplasty were classified into three groups as follows: (1) radial forearm (RF) group, (2) anterolateral thigh (ALT) group, and (3) flap combination (FC) group. Statistical analyses were performed to determine the significance of age and body mass index (BMI) as well as differences in the rates of postoperative complication, reoperation, esthetic acceptability, tactile or erogenous sensibility, and the ability to urinate while standing.

Results Ten cases were included in the RF group and 7 and 15 cases in the ALT and FC groups, respectively. With respect to BMI, the RF group (mean [standard deviation (SD)] = 25.9 [3.3]) showed significantly higher BMI than the ALT (21.7 [0.9]) or FC group (22.2 [4.5]). The RF (mean [SD] = 3.7 [0.4]) and ALT groups (3.5 [0.9]) had significantly higher esthetic acceptability evaluation scores (from 1 to 4) than the FC group (2.5 [1.2]). Moreover, the RF and ALT groups were superior than the FC group in terms of tactile or erogenous sensibility rates.

Conclusion BMI effected flap choices for phalloplasty because of the correlation between BMI and skin thickness. FC becomes an option between ALT flap and RF flap in terms of flap choice based on BMI. Our alternative algorithm for an ideal phalloplasty based on BMI will be useful for objective flap choices.

Planned and Unplanned Delayed Anterolateral Thigh Flap Phalloplasty

Background:

Pedicled anterolateral thigh (ALT) flap phalloplasty can be limited by inadequate perfusion. Vascular delay increases perfusion, as delay causes blood vessel formation by limiting the blood supply available to a flap before transfer. We hypothesized that delayed ALT flap phalloplasty would decrease rates of partial flap or phallus loss and other postoperative complications when compared with previously reported complication rates of undelayed single-stage ALT phalloplasty in our practice.

Methods:

A retrospective medical record review was performed on all phalloplasty patients in our practice between January 2016 and September 2019. We found those patients who had completed delayed ALT flap phalloplasty with at least 6 months of delay and 12 months of follow-up. For these patients, we recorded postoperative complications, simultaneous surgeries, subsequent surgeries, and demographic characteristics.

Results:

Five female-to-male transsexuals underwent delayed ALT flap phalloplasty (two were unplanned procedures, three were planned). Planned delay: The average time between Stage 1 and Stage 2 was 6.5 months. Complications for the planned delay cohort were as follows: partial loss of the neophallus not requiring repair (33%), urethral stricture requiring surgical repair (33%). Unplanned delay: The average time between Stage 1 and Stage 2 was 9.1 months. The following complication was seen in the unplanned delay cohort: urethral stricture requiring surgical repair (50%).

Conclusions:

Vascular delay of ALT flap phalloplasty is a successful emergency salvage procedure. Planned delay of ALT flaps provided similar results compared with those previously reported by our practice with standard single-stage approach.

Caring for Transgender Patients: Complications of Gender-Affirming Genital Surgeries

Patients who undergo gender-affirming genital surgeries may present to the emergency department for their postsurgical complications. In this paper, we briefly describe the transfeminine and transmasculine genital procedures, review the diagnosis and management of both common and potentially life-threatening complications, and discuss the criteria for hospitalization and time frame for surgical consultation and referral.

Multimodal evaluation of donor site morbidity in transgender individuals after phalloplasty with a free radial forearm flap: a case-control study

BACKGROUND

In phalloplasty, there is a lack of standardized follow-up examinations of motor function and strength after harvesting oversized radial forearm free flaps (RFFF).

METHODS

We evaluated the donor site of 20 transmen after phalloplasty, using a multimodal, standardized approach, assessing the following parameters: opposition of the thumb, composite range of motion of the finger joints, grip strength, mobility of the wrist, lesion of the superficial branch of the radial nerve, the dorsal branch of the ulnar nerve, the sensation of pain, and cold intolerance. The contralateral, nonoperated forearm was used as a control.

RESULTS

No impairment of the mobility of the thumb (Kapandji score median 10, range 5-10) or fingers (all fingers at both sides pulp-to-palm 0 cm, nail-to-table 0 cm) were detected. Grip strength (median 36,3kg, p=0.629) and wrist extension (62.5°vs.70°, p=0.357), flexion (70°vs.70°, p=0.535), pronation (90°vs.90°), supination (90°vs.90°), radial (30°vs.30°, p=0.195), and ulnar deviation (40°vs.50°, p=0.125) did not statistically differ between donor and control hand. Injury of the dorsal branch of the ulnar nerve was uncommon (0% hypoesthesia, 10% positive Tinel's sign). We did not observe any persistent pain of the donor forearm (NRS median 0, range 0-9). We did observe irritation of the superficial branch of the radial nerve (hypoesthesia 40%, neuroma 45%).

CONCLUSION

The harvest of an oversized RFFF for phalloplasty does not cause any significant difference in motor function or strength between the donor and nonoperated hand. A potential risk of injuring the radial nerve branch is to be avoided. An aesthetic impairment could be addressed in future studies.

Total phallic construction techniques in transgender men: an updated narrative review

From 2012, the World Professional Association Transgender Health defined a structured therapeutic path and standards of care for transgender patients undergoing genital gender affirming surgery (GGAS). The main goal of GGAS in transgender males is to provide patients with an aesthetically appealing appearance of the neophallus that should allow standing micturition and enabling penetrative intercourse along with erogenous and tactile sensitivity. The optimal procedure should be safe, reproducible and performed in the fewest number of surgical stages. The ideal technique for total phallic construction (TPC) has not yet been demonstrated; TPC remains challenging and, from a functional point of view, it is also make more demanding as yet there are no perfect replacement materials for erectile and urethral tissues. Several procedures and different type of flaps (pedicled and free-flaps) have been proposed and investigated over time to address TPC with significant advances over the years especially after microsurgical procedures introduction. Due to its high complexity TPC is not free from complications. Local tissue ischaemic complications, complete and partial flap loss, donor site morbidity and urethral complications (fistulae and strictures) are reported. This narrative review aims to provide the readers with a contemporary overview of surgical procedures for TPC in transgender males focusing on key surgical steps, as well as surgical and functional outcomes.

The role of androgens in clitorophallus development and possible applications to transgender patients

BACKGROUND

The clitorophallus, or glans, is a critical structure in sexual development and plays an important role in how gender is conceptualized across the life span. This can be seen in both the evaluation and treatment of intersex individuals and the use of gender-affirming masculinizing therapies to help those born with a clitoris (small clitorophallus with separate urethra) enlarge or alter the function of that structure.

OBJECTIVES

To review the role of testosterone in clitorophallus development from embryo to adulthood, including how exogenous testosterone is used to stimulate clitorophallus enlargement in masculinizing gender-affirming therapy.

MATERIALS AND METHODS

Relevant English-language literature was identified and evaluated for data regarding clitorophallus development in endosex and intersex individuals and the utilization of hormonal and surgical masculinizing therapies on the clitorophallus. Studies included evaluated the spectrum of terms regarding the clitorophallus (genital tubercle, clitoris, micropenis, penis).

RESULTS

Endogenous testosterone, and its more active metabolite dihydrotestosterone, plays an important role in the development of the genital tubercle into the clitorophallus, primarily during the prenatal and early postnatal periods and then again during puberty. Androgens contribute to not only growth but also the inclusion of a urethra on the ventral aspect. Exogenous testosterone can be used to enlarge the small clitorophallus (clitoris or micropenis) as part of both intersex and gender-affirming care (in transmasculine patients, up to 2 cm of additional growth). Where testosterone is insufficient to provide the degree of masculinization desired, surgical options including phalloplasty and metoidioplasty are available.

DISCUSSION AND CONCLUSION

Endogenous testosterone plays an important role in clitorophallus development, and there are circumstances where exogenous testosterone may be useful for masculinization. Surgical options may also help some patients reach their personal goals. As masculinizing gender-affirming care advances, the options available for clitorophallus modifications will likely continue to expand and improve.

Single versus two-stage phalloplasty for transgender female-to-male patients: a systematic review of the literature

Phalloplasty is the main treatment for gender dysphoria disorder. It is difficult to ascertain if staging of phalloplasty influences the rate of complications. We aim to describe and compare the rates of complication between single versus two-stage phalloplasty for transgender female-to-male patients. PubMed, Ovid Medline, EMBASE and SCOPUS databases were queried for studies reporting complications of female-to-male transgender patients who underwent phalloplasty. The keywords "phalloplasty", "female to male", "outcome", "complication" and synonyms in different combinations were used for the search. Only studies that could identify whether phallic shaft creation was performed in a single or two-stage procedure were included. From a total of 336 articles, 20 met the inclusion criteria. Sixteen studies reported complications associated with a single-stage phalloplasty and seven studies identified complications after a two-stage procedure. The most common complications found for both groups of staging were fistula, stricture and total/partial flap necrosis. Patients who underwent two-stage phalloplasty had higher complication rates (partial or total flap necrosis and fistulas), compared with the single-stage procedure (P<0.05). In conclusion, this systematic review identified the impact of staging in the rate of complications related to phalloplasty for transgender female-to-male patients; a two-stage phalloplasty has a higher rate of complications.

An Updated Overview of Gender Dysphoria and Gender Affirmation Surgery: What Every Plastic Surgeon Should Know

Gender dysphoria refers to the medical condition experienced by individuals whose physical anatomy is not consistent with their gender identity. Surgery is a safe and effective treatment for many individuals, yet the current demand for surgery exceeds the number of trained surgeons. This article reviews gender-affirming surgical procedures and emphasizes an individualized approach within the context of a multidisciplinary team. We review pre-, intra-, and postoperative care including the preoperative requirements for surgery.
