Neophalloplasty in female-to-male transsexuals with the island tensor fasciae latae 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.

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.

A Systematic Review of Staging and Flap Choice in Gender-Affirming Phalloplasty

Background As phalloplasty becomes more routinely performed, there is a growing need for an evidence base to guide surgical decision-making. Recent reviews have suggested that flap type and number of stages may affect the high rates of urethral complications seen with phalloplasty, but no rigorous comparison of both has been performed.

Methods A systematic review was conducted across PubMed, Google Scholar, and ScienceDirect (PROSPERO #158722). All included studies examined urethral complications following gender-affirming phalloplasty in transgender men. Data were extracted in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations system. All searches, extractions, and grading were completed by two authors.

Results Twenty-five studies were included with a total of 1,674 patients. Identified flap types included radial forearm, anterolateral thigh, abdominal, and fibular flaps. Surgical techniques varied widely within the flap types. Number of stages ranged from one to four. Stricture and fistula were the most frequently reported complications with considerable variation in the reported rates between studies, even within singular flap types. Data extraction indicated serious quality issues with the published literature, with the majority of studies at high risk of bias due to short follow-up times, inconsistent and incomplete reporting of outcomes, and inconsistent reporting of surgical technique.

Conclusion To date, there is insufficient data to support a preferred flap type to minimize the urethral complication rates of phalloplasty. Further high-quality literature is required to determine the impact of potential factors affecting complications of gender-affirming phalloplasty. Improved literature quality may be facilitated by a standardized set of reporting guidelines.

Options for Masculinizing Genital Gender Affirming Surgery: A Critical Review of the Literature and Perspectives for Future Directions

INTRODUCTION

Masculinizing genital gender affirmation surgery (MgGAS) has witnessed significant change in recent years. With the increasing number of patients seeking out GAS, optimization of techniques is mandated.

OBJECTIVES

To critically review the evolution of MgGAS, in a manner that encompasses the history and scope of the procedures, including phalloplasty with and without urethral lengthening, metoidioplasty with and without urethral lengthening, penile prosthesis placement, scrotoplasty, testicular prosthesis placement, vaginectomy, and hysterectomy.

METHODS

A comprehensive literature review was conducted in accordance with PRISMA guidelines, using PubMed. For our search, we generated a comprehensive list of MgGAS, combined with synonyms for GAS to ensure that articles included transgender cohorts. We identified a total of 547 articles from the search terms. Of these articles, 144 abstracts were relevant. Among these abstracts, 108 manuscripts were reviewed in full of which 98 were acceptable for inclusion. We excluded non-English-language studies without translation and studies that did not describe primary gGAS (eg, revision surgeries).

RESULTS

The evolution of MgGAS encompasses mostly refinements of pre-existing procedures, rather than new techniques or "watershed" procedures. The literature is somewhat lacking in outcomes-reporting that identifies the specific anatomy and surgical technique(s) used during gGAS. Without clarity regarding anatomy and technique, it is not feasible to compare surgical outcomes.

CONCLUSION

There is no ideal MgGAS; thus, it is critical that the physician assist the patient in understanding the outcomes and potential morbidity of the procedures to make the most informed decision. We envision that the future of MgGAS will advance with refinement of surgical techniques that minimize complications, improvement of tissue therapeutic technologies, new surgical tools and prosthetics designed for gGAS, advances in aftercare, and an immense selection of surgical options.

Terminology of the branches of the lateral circumflex femoral artery: Who is Who?

The anterolateral thigh flap and the tensor fasciae latae flap are supplied by the lateral circumflex femoral artery (LCFA). Different branching patterns of the LCFA have been described, leading to confusion, discrepancies and difficulties in clinical and cadaveric study comparisons. The aim of this study was to evaluate the branching patterns of the LCFA in dissected lower limbs and propose a simplified nomenclature. One hundred and two lower limbs fixed with Thiel's method were investigated. Meticulous dissection was performed, and the branching pattern of the arteries was documented by illustration and photography. These were analysed and allocated to the currently existing terminologies regarding the numbers of the branches (Part 1), and these subgroups were evaluated according to the variability of the trunk formations (Part 2). In Part 1, four subgroups could be classified (A, B, C and D). Group A included a total number of three branches (n = 50), Group B included four (n = 41), Group C included five (n = 5) and Group D included only two branches (n = 6). Part 2 showed in total 11 different trunk variations. Group A had four trunk variations: A1 (n = 38), A2 (n = 5), A3 (n = 2) and A4 (n = 6); Group B also had four variations: B1 (n = 16), B2 (n = 18), B3 (n = 3) and B4 (n = 4); Group C displayed two variations: C1 (n = 1) and C2 (n = 4); and in Group D, there was only one variation observed D1 (n = 6). Branching patterns were highly variable and inconsistent in terms of the number of branches and trunk variations, which resulted in different possible and justified interpretations and classifications. A new terminology should be defined cooperatively among anatomists and clinicians that will be useful for everybody. We propose a terminology oriented to the associated muscles.

Minimising the donor area morbidity of radial forearm phalloplasty using prefabricated thigh flap: A new technique

Phalloplasty is indicated in various conditions of penile loss or absence. There are numerous techniques for phalloplasty including the pedicle and free flaps with the ultimate goal of micturition in standing position, attaining adequate size, aesthesis and sensations for sexual intercourse. Radial forearm phalloplasty is the gold standard flap to achieve above results but gives a very bad scar on the forearm. We present a technique of using prefabricated thigh flap to reduce the morbidity of donor area. The descending branch of lateral circumflex femoral pedicle was placed in a subcutaneous plane over tissue expander. After attaining an adequate size of flap with tissue expansion, it was delayed 3 weeks before phalloplasty. Prefabricated flap was thin and of large size replicating the radial forearm flap used for phalloplasty. Whole forearm defect was covered with the thigh flap, and the thigh could be closed primarily. This new technique of using prefabricated thigh flap has significantly reduced the donor site morbidity both aesthetically and functionally without the use of skin grafting in the whole procedure.

Phalloplasty: A Review of Techniques and Outcomes

BACKGROUND

Acquired or congenital absence of the penis can lead to severe physical limitations and psychological outcomes. Phallic reconstruction can restore various functional aspects of the penis and reduce psychosocial sequelae. Moreover, some female-to-male transsexuals desire creation of a phallus as part of their gender transition. Because of the complexity of phalloplasty, there is not an ideal technique for every patient. This review sets out to identify and critically appraise the current literature on phalloplasty techniques and outcomes.

METHODS

A comprehensive literature search of the MEDLINE, PubMed, and Google Scholar databases was conducted for studies published through July of 2015 with multiple search terms related to phalloplasty. Data on techniques, outcomes, complications, and patient satisfaction were collected.

RESULTS

A total of 248 articles were selected and reviewed from the 790 identified. Articles covered a variety of techniques on phalloplasty. Three thousand two hundred thirty-eight patients underwent phalloplasty, with a total of 1753 complications reported, although many articles did not explicitly comment on complications. One hundred four patients underwent penile replantation and two underwent penile transplantation. Satisfaction was high, although most studies did not use validated or quantified approaches to address satisfaction.

CONCLUSIONS

Phalloplasty techniques are evolving to include a number of different flaps, and most techniques have high reported satisfaction rates. Penile replantation and transplantation are also options for amputation or loss of phallus. Further studies are required to better compare different techniques to more robustly establish best practices. However, based on these studies, it appears that phalloplasty is highly efficacious and beneficial to patients.

Phalloplasty: The dream and the reality

Phalloplasty has come a long way as Plastic Surgery has evolved over the years. The complication ridden multistage tube pedicles popularized by Gillis were, with the advent of microsurgery, replaced by radial forearm flaps. The composite osteo-cutaneous version of this flap promised ‘All for one and one for all’ assuring both a reliable urinary conduit and a phallus stiffener. Prelamination and prefabrication to make the neo-urethra came with the promise of reducing both fistula and strictures but that did not happen and flap failure rates increased. Penile stiffeners of various types have been introduced; the artificial ones were associated with high infection and failure rates and are best inserted after the neo-penis regains some sensitivity. With the introduction of perforator flaps the Anterolateral thigh flap in its sensate pedicled form has started replacing the Radial forearm free flap as the first choice flap because of a hidden donor area and lack of microsurgical expertise requirement. Being sensate it tolerates a stiffener better. It is now possible to reconstruct an aesthetically pleasing glans as well, thus meeting both the aesthetic and functional desires of the patient. Complications encountered in this reconstructive effort include flap failure, urethral fistula, urethral stricture and stiffener related problems.

Surgical outcomes and patients' satisfaction with suprapubic phalloplasty

INTRODUCTION

Many techniques, specifically forearm free flap phalloplasty, are used in penile reconstructive surgery. Although satisfying, a major disadvantage is the large, stigmatizing scar on the donor site, which leads many patients to explore alternatives.

AIM

The aim of this study is to assess the outcomes and satisfaction of patients offered the choice between metaidioplasty, forearm free flap, and suprapubic phalloplasty.

METHODS

Medical outcomes from the three-stage surgery were collected from the hospital files of 24 patients, who were also interviewed to assess their satisfaction, sexual function, and psychosexual well-being.

MAIN OUTCOME MEASURES

Medical complications, anthropometric measures, and interviewing questionnaire on satisfaction with appearance, sexual function, and psychological variables.

RESULTS

Duration of surgery and of hospital stay was relatively short in the first (1 hour 30 minutes; 3 days) and last (1 hour 40 minutes; 3 days) stage of surgery involving tissue expansion and neophallus release. These two stages were associated with few complications (17% and 4% minor complications respectively, 12% additional complications with hospitalization for the first stage). The second stage involving tubing was associated with longer surgery and hospital stay (2 hour 15 minutes; 5 days) and had more complications (54% minor complications and 29% requiring hospitalization) although fewer than one-step surgery. No loss of neophallus was reported. Overall, 95% of patients were satisfied with their choice of phalloplasty, 95% with the appearance, 81% with the length (Mean = 12.83 cm), and 71% with the circumference (Mean = 10.83 cm) of their neophallus. Satisfactory appearance was significantly correlated (P < 0.01) with penile length (r = 0.69) and diameter (r = 0.77). Sexual satisfaction was significantly correlated with penile diameter (r = 0.758), frequency of orgasm (r = 0.71), perceived importance of voiding while standing (r = 0.56), presurgery satisfaction with sexuality (r = 0.58), current masculine-feminine scale (r = 0.58), attractive-unattractive scale (r = 0.69), and happy-depressed scale (r = 0.63).

CONCLUSION

Suprapubic phalloplasty, despite the lack of urethroplasty, offers an interesting alternative for patients concerned with the stigmatizing scar on the donor site.

Sex Reassignment Surgery in the Female-to-Male Transsexual

In female-to-male transsexuals, the operative procedures are usually performed in different stages: first the subcutaneous mastectomy which is often combined with a hysterectomy-ovarectomy (endoscopically assisted). The next operative procedure consists of the genital transformation and includes a vaginectomy, a reconstruction of the horizontal part of the urethra, a scrotoplasty and a penile reconstruction usually with a radial forearm flap (or an alternative). After about one year, penile (erection) prosthesis and testicular prostheses can be implanted when sensation has returned to the tip of the penis. The authors provide a state-of-the-art overview of the different gender reassignment surgery procedures that can be performed in a female-to-male transsexual.

Sensibility following innervated free radial forearm flap for penile reconstruction

BACKGROUND

The free radial forearm flap has proven to be reliable for penile reconstruction. The purpose of this study was to determine whether neurotization of this flap improved sensation of the reconstructed penis.

METHODS

A long-term follow-up study of 45 patients undergoing penile reconstruction using free radial forearm flap was performed; 28 of the 45 patients received an innervated flap, and 17 received a noninnervated flap. A nerve repair between the dorsal nerve of the penis and the lateral antebrachial cutaneous nerve was performed for innervation. Sensory testing, including pain perception, temperature perception, vibratory threshold, and static two-point discrimination, was performed by one blinded examiner in a standardized pattern.

RESULTS

Mean follow-up time was 9.1 years. Mean patient age was 26.4 years (range, 18 to 48 years). Postoperative pain perception and vibratory threshold were similar between the two groups in the proximal part of the neophallus but were significantly better in the innervated flaps (p < 0.01) in the distal part. Noninnervated flaps displayed a pattern of increasing sensibility from the distal part toward the proximal part, whereas innervated flaps regained sensation throughout. The innervated group had a better result of temperature perception and static two-point discrimination in both the proximal and the distal parts.

CONCLUSIONS

Innervation of free radial forearm flap provides improved sensation to the reconstructed penis. If it is possible to find the functional recipient nerve, innervation should always be conducted.

Penile reconstruction: is the radial forearm flap really the standard technique?

BACKGROUND

The ideal goals in penile reconstruction are well described, but the multitude of flaps used for phalloplasty only demonstrates that none of these techniques is considered ideal. Still, the radial forearm flap is the most frequently used flap and universally considered as the standard technique.

METHODS

In this article, the authors describe the largest series to date of 287 radial forearm phalloplasties performed by the same surgical team. Many different outcome parameters have been described separately in previously published articles, but the main purpose of this review is to critically evaluate to what degree this supposed standard technique has been able to meet the ideal goals in penile reconstruction.

RESULTS

Outcome parameters such as number of procedures, complications, aesthetic outcome, tactile and erogenous sensation, voiding, donor-site morbidity, scrotoplasty, and sexual intercourse are assessed.

CONCLUSIONS

In the absence of prospective randomized studies, it is not possible to prove whether the radial forearm flap truly is the standard technique in penile reconstruction. However, this large study demonstrates that the radial forearm phalloplasty is a very reliable technique for the creation, mostly in two stages, of a normal-appearing penis and scrotum, always allowing the patient to void while standing and in most cases also to experience sexual satisfaction. The relative disadvantages of this technique are the rather high number of initial fistulas, the residual scar on the forearm, and the potential long-term urologic complications. Despite the lack of actual data to support this statement, the authors feel strongly that a multidisciplinary approach with close cooperation between the reconstructive/plastic surgeon and the urologist is an absolute requisite for obtaining the best possible results.

Thrombotic cutaneous gangrene with autoamputation of the penis: a rare extracolonic manifestation of ulcerative colitis in a child

We present a pediatric patient with ulcerative colitis who developed thrombotic cutaneous gangrene involving skin of the lower chest, abdomen, back, bilateral buttocks, bilateral thighs, perineum, and genitalia, ultimately resulting in autoamputation of the glans penis. After an extensive review of the literature, we describe the diagnosis and management of this devastating condition.

Innervated island pedicled anterolateral thigh flap for neo-phallic reconstruction in female-to-male transsexuals

Many techniques have been described to create an aesthetic and functional neo-phallus after penile amputation or in female-to-male transsexuals. Microsurgical free-flap phalloplasty seems to be the preferred method of penile reconstruction. For many years the radial forearm free flap has been considered the best procedure, but other flaps have been attempted to minimize donor site morbidity and optimize outcome. Pedicled flaps are considered to be reliable and to decrease the risk of total failure. Recently, a one-stage non-microsurgical technique was described for phallic reconstruction in a young male patient. We report successful total phallic reconstruction in a female-to-male transsexual patient using an island pedicled anterolateral thigh (ALT) flap. Urethral reconstruction was left as a possible further procedure due to patient's preference. A malleable soft silicone penile prosthesis was inserted within the flap and the lateral cutaneous femoral nerve stump was sutured to the dorsal clitoris branch from the pudendal nerve for flap sensation. After 6 months, the patient demonstrated successful aesthetic and functional reconstruction referring to satisfactory sexual activity. To our knowledge, this is the first report of an innervated island pedicled ALT flap used for female-to-male penile reconstruction in a transsexual patient. The pedicled ALT flap may be a reliable option to avoid visible scarring at the donor site on exposed parts of the body, and reduce the risk of total flap failure from microsurgical procedures for reconstruction of a neo-phallus in this increasing population of patients.

New technique of total phalloplasty with reinnervated latissimus dorsi myocutaneous free flap in female-to-male transsexuals

From December 2001 to September 2005, the technique of total penile reconstruction with a reinnervated free latissimus dorsi myocutaneous flap was used in 22 patients (24-38 years old) with gender dysphoria. These patients were followed up for at least 11 months (range, 11-44 months). All flaps survived. Complications include hematoma (7 cases), vascular thrombosis (2 cases), partial necrosis (1 case), excessive swelling of the neophallus (3 cases), and skin graft loss at the donor site (1 case). Of the 19 patients included in the final evaluation, the transplanted muscle was able to obtain contraction in 18 (95%) cases and 8 patients (42%) had sexual intercourse by contracting the muscle to stiffen and move the neopenis. The described technique of neophalloplasty proved to be a reliable technique and the muscle movement in the neophallus can be expected in almost all cases. The muscle contraction in the neophallus leads to "paradox" erection-stiffening, widening, and shortening of the neopenis, which allows for sexual intercourse in some patients. Subsequent reconstruction of the urethra is possible.

A true one-stage nonmicrosurgical technique for total phallic reconstruction

A new nonmicrosurgical technique for one-stage total phallic reconstruction is presented. In this procedure, an innervated anterolateral thigh (ALT) flap including the medial half of the fascia latae is combined with a sartorius perforator flap. Both flaps are elevated together as an island chimeric flap based on the lateral circumflex femoral vessels and tunneled to the recipient area. The neourethra is created with thin and hairless skin of the sartorius perforator flap, while the ALT flap is used to construct the shaft and glans of the neophallus. The rigidity was provided with a penile prosthesis covered with a neotunica albuginea created with vascularized fascia latae for the first time in the literature. The lateral femoral cutaneous nerve of the ALT flap is coapted to the pudendal nerve to provide erogenous sensibility. Here, a 15-year-old male in whom this new procedure was used for one-stage total phallic reconstruction is presented. Two years of follow-up revealed that an esthetically acceptable and functional neopenis with a nonhairy competent urethra, erogenous sensitivity, and a proper rigidity was achieved with no complication. This new technique, namely, the "Istanbul on the thigh" flap, is a one-stage, safe, and timesaving technique which fulfills all essential goals of phallic reconstruction but does not require microsurgical equipment and expertise. Moreover, the donor scar is located at an unexposed area, easy to conceal. Although more clinical experience is needed, this new procedure seems to be a useful alternative in phallic reconstruction.

Glans, urethra, and corporeal body reconstruction by free osteocutaneous forearm flap transfer

A 30-year-old man presented with short penile corporeal bodies hosting a 3-cm fibular graft, absence of glans, and proximal penile hypospadias. The patient underwent a forearm flap transfer with an "umbrella-like" skin flap for glans and urethra reconstruction and a radial bone strut to allow for rigidity. The postoperative course was uneventful and the patient was followed-up with fluximetry tests at 2 weeks, 4 weeks, 2 months, and 6 months, showing no stenoses and normal stable values. Masturbation started at month 3 postoperatively and intercourse began at month 4, with both resulting in orgasm. At 6 months postoperatively, touch sensation, pain, and sensibility to heat were present, but sensibility to cold was absent. Light touch pressure was detected with 4.74 Semmes-Weinstein monofilament, and static two-point discrimination was 20 mm at the neoglans. One year postoperatively, a stable increased length up to 9 cm at rest and 13 cm at erection with a satisfactory anatomic definition could still be proved.

Phalloplasty in a female-to-male transsexual using a double-pedicle composite groin flap

An operative procedure for phalloplasty in a 21-year-old female-to-male transsexual is reported that uses a double-pedicle composite groin flap. The surgical technique is described. Both the deep and the superficial circumflex iliac vessels were included in the pedicle to ensure well-vascularized extended skin and bone in the flap. The procedure was planned in two stages to prefabricate a neourethra before transfer of the flap. The large skin island and bone with its dual blood supply enabled the authors to reconstruct the penis in an appropriate size and stiffness without vascular compromise. The flap donor site was sutured easily. The patient is pleased with the operative results. His voiding and sexual intercourse are acceptable according to his report.

Surgery of the penis: reconstruction and prostheses

Implantation of penile prostheses was a very popular topic in the published literature on reconstructive urological surgery in the year 2000. Monocomponent, multicomponent, semirigid and inflatable prosthesis techniques were investigated. The best results were obtained with multicomponent inflatable prostheses. For penile reconstruction, various techniques were described. All authors used myocutaneous sensitive forearm flaps. Good results were reported.
