A method of preserving the glans penis as a clitoris in sex conversion operations in male transsexuals

Application of embryonic equivalents in male-to-female sex reassignment surgery

Introduction:

The feeling of incongruence between phenotypic sex and psychological recognition of self-gender is termed gender dysphoria. Transsexualism is the most extreme form of this disorder.

Aims and Objectives:

The aims and objectives of the study are to evaluate the esthetic and functional outcome of embryonic equivalents-based male-to-female sex reassignment surgery in transwomen using the institutional scoring system.

Materials and Methods:

Thirty transwomen who had undergone male-to-female embryonic equivalents-based sex reassignment surgery (MFEEbSRS) from October 2012 to March 2016 were retrospectively studied. The outcome was evaluated by two independent plastic surgeons, based on interview with the individuals, visual assessment, and measurements.

Surgical Technique:

Clitoris was created from reduced glans on dorsal penile pedicle mounted on the crura of the conjoined corpora cavernosa. De-gloved unfurled proximal penile skin formed the introitus, hood for clitoris and labia minora. Neo-external urethral meatus was fashioned from the distal portion of the bulbar urethra. Distal de-gloved inverted penile tube flap was used for the creation of neovagina. Reduced scrotal flaps formed the labia majora.

Observation and Results:

The maximum length of neovagina in the study was 12 cm, and the average length was 9.8 cm. Based on our institutional scoring system for the assessment of esthetic and functional outcome, we got excellent results in all transwomen.

Conclusion:

The esthetic and functional outcome in all the patients was good. All patients were relieved of their primordial feminine tension and satisfied with the surgery. Their personality, lifestyle, and self-esteem improved remarkably following surgery.

Sigma-lead Male-to-Female Gender Affirmation Surgery: Blending Cosmesis with Functionality

Supplemental Digital Content is available in the text.

Background:

Current male-to-female (MtF) sex-reassignment-surgery techniques have not been fully successful to achieve the ideal objectives. The ordeal of multiple procedures, associated complications, and suboptimal results leads to high rate of dissatisfaction. We have tried to overcome functional inadequacy and address the esthetic issues for outer genitalia and vagina with our innovative “true shape sigma-lead SRS: Kaushik’s technique,” which has now become the technique of choice for MtF genital SRS for our patients.

Methods:

Between April 2007 and April 2017, authors performed 386 sigma-lead SRS in MtF transsexuals. Results were analyzed based on complications, resurgeries, and esthetic/functional outcomes. Corrective SRS using rectosigmoid constituted 145 cases and is not a part of this study.

Results:

Maximum follow-up was 7 years (average 34 months). Seventy-eight (20.2%) patients had complications, majority being minor (97.4%). Forty-four (11.4%) required resurgeries, 10 (2.6%) were corrective for introital stricture and mucosal prolapse, whereas 34 (8.8%) opted for optional minor esthetic enhancement. The overall satisfaction rate for cosmetic and functional outcomes was 4.7 out of 5. In addition to review of the literature, innovations in the technique have been explained.

Conclusions:

Kaushik’s sigma-lead MtF SRS technique is a step short to become the gold standard of genital SRS because it has proven to be safe and reliable. It allows faster healing, minimal dilation, and nearly natural cosmetic results in the form of clitoris/clitoral hood, labia minora, labia majora along with self-lubricating, fully deep, and sensate neovagina with orgasmic capabilities. This is perhaps the largest reported series of rectosigmoid use in transsexuals carried out for primary vaginoplasty.

An overview of neovaginal reconstruction options in male to female transsexuals

Transsexualism is a complex condition in which the person experiences the inconsistency between the desired gender and their biological gender. Absence of the vagina is devastating in male to female transsexuals. Creation of the neovagina is the main surgical problem in these patients. Historically, beginnings of the neovaginal creation have their roots in the treatment of Mayer-Rokitansky syndrome and conditions such as cloacal anomalies, certain intersex disorders, vaginal malignancies, or severe vaginal trauma, but have more recently found great purpose in male to female sex reassignment surgery. Many operative procedures have been described but none is ideal. Therefore, the search for new, improved solutions continues. In neovaginoplasty reconstruction of the vulvovaginal complex is performed in its entity. The gold standard in neovaginal reconstruction in male to female sex reassignment surgery is penile skin inversion technique with or without scrotal flaps, which enables adequate sensation of the neovagina, good neovaginal depth, good erotic sensitivity of the neclitoris, and esthetically acceptable labia minora and maiora.

Current management of male-to-female gender identity disorder in the UK

Gender identity disorder (GID), or transsexualism as it is more commonly known, is a highly complex clinical entity. Although the exact aetiology of GID is unknown, several environmental, genetic and anatomical theories have been described. The diagnosis of GID can be a difficult process but is established currently using standards of care as defined by the Harry Benjamin International Gender Dysphoria Association. Patients go through extensive psychiatric assessment, including the Real Life Experience, which entails living in the desired gender role 24 h a day for a minimum period of 12 months. The majority of GID patients will eventually go on to have gender realignment surgery, which includes feminising genitoplasty. The clinical features, diagnostic approach and management of male-to-female GID in the UK are reviewed, including the behavioural, psychological and surgical aspects.

Development of Feminizing Genitoplasty for Gender Dysphoria

INTRODUCTION

Determining the history and development of feminizing genitoplasty is fascinating and instructive but fraught with difficulty. Earliest examples relate to practices carried out in ancient cultures. Gender reassignment surgery (GRS) developed from reconstructive procedures for congenital abnormalities. Some surgery was disguised, techniques were not recorded, and operations were carried out in secret.

AIM

The aim of this article is to review the historical development of male-to-female GRS.

METHODS

Information was gleaned from Medline and general Internet searches. Further evidence was found by reviewing the references of early articles. A fascinating insight was also found in the autobiographies of GRS patients.

RESULTS

The first recorded case was by Abrahams in 1931. Techniques evolved from the early vaginal absence work of Beck and Graves. Pioneers of GRS were Sir Harold Gillies in England and Georges Burou of Casablanca. In the 1950s, they both used invagination of the penile skin sheath to form a vagina. Howard Jones, of Johns Hopkins, published the second classic technique using penile and scrotal skin flaps. These two methods form the basis of male-to-female GRS today. The history of GRS reveals a struggle to improve functionality as well as cosmesis. In particular, the neovagina but also a functioning neoclitoris, which has developed from a cosmetic swelling into an innovated organ, derived from the glans penis and harvested penile neurovascular bundle.

CONCLUSIONS

Improved function and cosmesis continue to be the aim of the gender dysphoria surgeon. However, this review suggests the future management of transwomen should address not only refinements of surgical techniques but also prospective collection of posttreatment quality-of-life issues.

Genital sensitivity after sex reassignment surgery in transsexual patients

BACKGROUND

Tactile and erogenous sensitivity in reconstructed genitals is one of the goals in sex reassignment surgery. Since November 1993 until April 2003, a total of 105 phalloplasties with the radial forearm free flap and 127 vaginoclitoridoplasties with the inverted penoscrotal skin flap and the dorsal glans pedicled flap have been performed at Ghent University Hospital. The specific surgical tricks used to preserve genital and tactile sensitivity are presented. In phalloplasty, the dorsal hood of the clitoris is incorporated into the neoscrotum; the clitoris is transposed, buried, and fixed directly below the reconstructed phallic shaft; and the medial and lateral antebrachial nerves are coapted to the inguinal nerve and to one of the 2 dorsal nerves of the clitoris. In vaginoplasty, the clitoris is reconstructed from a part of the glans penis inclusive of a part of the corona, the inner side of the prepuce is used to reconstruct the labia minora, and the penile shaft is inverted to line the vaginal cavity.

MATERIAL AND METHODS

A long-term sensitivity evaluation (performed by the Semmes-Weinstein monofilament and the Vibration tests) of 27 reconstructed phalli and 30 clitorises has been performed.

RESULTS

The average pressure and vibratory thresholds values for the phallus tip were, respectively, 11.1 g/mm and 3 microm. These values have been compared with the ones of the forearm (donor site). The average pressure and vibratory thresholds values for the clitoris were, respectively, 11.1 g/mm and 0.5 microm. These values have been compared with the ones of the normal male glans, taken from the literature. We also asked the examined patients if they experienced orgasm after surgery, during any sexual practice (ie, we considered only patients who attempted to have orgasm): all female-to-male and 85% of the male-to-female patients reported orgasm.

CONCLUSION

With our techniques, the reconstructed genitalia obtain tactile and erogenous sensitivity. To obtain a good tactile sensitivity in the reconstructed phallus, we believe that the coaptation of the cutaneous nerves of the flap with the ilioinguinalis nerve and with one of the 2 nerves of the clitoris is essential in obtaining this result. To obtain orgasm after phalloplasty, we believe that preservation of the clitoris beneath the reconstructed phallus and some preservation of the clitoris hood are essential. To obtain orgasm after a vaginoplasty, the reconstruction of the clitoris from the neurovascular pedicled glans flap is essential.

Gender identity disorder: general overview and surgical treatment for vaginoplasty in male-to-female transsexuals

LEARNING OBJECTIVES

After studying this article, the participant should be able to discuss: 1. The terminology related to male-to-female gender dysphoria. 2. The different theories regarding cause, epidemiology, and treatment of gender dysphoria. 3. The surgical goals of sex reassignment surgery in male-to-female transsexualism. 4. The surgical techniques available for sex reassignment surgery in male-to-female transsexualism.

BACKGROUND

Gender identity disorder (previously "transsexualism") is the term used for individuals who show a strong and persistent cross-gender identification and a persistent discomfort with their anatomical sex, as manifested by a preoccupation with getting rid of one's sex characteristics, or the belief of being born in the wrong sex. Since 1978, the Harry Benjamin International Gender Dysphoria Association (in honor of Dr. Harry Benjamin, one of the first physicians who made many clinicians aware of the potential benefits of sex reassignment surgery) has played a major role in the research and treatment of gender identity disorder, publishing the Standards of Care for Gender Dysphoric Persons.

METHODS

The authors performed an overview of the terminology related to male-to-female gender identity disorder; the different theories regarding cause, epidemiology, and treatment; the goals expected; and the surgical technique available for sex reassignment surgery in male-to-female transsexualism.

RESULTS

Surgical techniques available for sex reassignment surgery in male-to-female transsexualism, with advantages and disadvantages offered by each technique, are reviewed. Other feminizing nongenital operative interventions are also examined.

CONCLUSIONS

This review describes recent etiopathogenetic theories and actual guidelines on the treatment of the gender identity disorder in male-to-female transsexuals; the penile-scrotal skin flap technique is considered the state of the art for vaginoplasty in male-to-female transsexuals, whereas other techniques (rectosigmoid flap, local flaps, and isolated skin grafts) should be considered only in secondary cases. As techniques in vaginoplasty become more refined, more emphasis is being placed on aesthetic outcomes by both surgeons and patients.

Male perineogenital anatomy and clinical applications in genital reconstructions and male-to-female sex reassignment surgery

To determine the possibility of providing alternative surgical techniques for male genital reconstruction and for male-to-female sex reassignment surgery, the authors undertook an anatomic investigation of the perineogenital region in male cadavers. Anatomic dissection was performed on 14 male adult human cadavers (fresh and formalin-preserved) studying the main afferent vessels to the anterior perineal region and their mean internal diameters: deep external pudendal artery (0.60 mm), superficial perineal artery (0.50 mm), and funicular artery (0.37 mm). We established their exact topography, together with vascular anatomic variations, main vascular anastomosis circuits (base of the penis, scrotal septum, and perineal fat and lateral spermatic-scrotal fascia), angiosomes, anatomy of the rectovesical septum cavity, and their "critical" key points of dissection. The authors discuss the clinical possibility of elevation of a "tree" of previously described paragenital-genital flaps including mainly those based on the terminal branches of the internal pudendal vascular system, the erectile tissue pedicled flaps, and finally, flaps of the external pudendal system. The authors indicate the concrete vascularization system for each flap.

Vaginoplasty in male transsexuals using penile skin and a urethral flap

OBJECTIVES

To describe and present the results of a one-stage vaginoplasty in male-to-female sex reassignment surgery.

PATIENTS AND METHODS

The present technique is based on penile disassembly and the use of all penile components for vaginoplasty (except the corpora cavernosa). The neovagina consists of two parts; a long vascularized urethral flap and a pedicled island tube skin flap created from the penile skin. The urethral flap is embedded into the skin tube. The tube, consisting of skin and the urethral flap, is inverted, thus forming the neovagina. The new vagina is inserted into the previously prepared perineal cavity between the urethra, bladder and rectum. The neovagina is then fixed to the sacrospinous ligament. The labia minora and majora are formed from remaining penile and scrotal skin. The new method was used in 89 patients (mean age 28 years, range 18-56) with a mean (range) follow-up of 4. 6 (0.25-6) years.

RESULTS

Good cosmetic and functional results were obtained in 77 of the 89 patients (87%). Importantly, the neovagina produced in most patients was of satisfactory depth and width. There was only one major complication, a rectovaginal fistula caused by intraoperative injury to the rectum.

CONCLUSIONS

The technique produces a vagina with more normal anatomical and physiological characteristics than those produced by other methods, as all the penile components are used (except for the corpora cavernosa) to form almost normal external female genitalia. Vaginoplasty using pedicled penile skin with a urethral flap is a good alternative to other methods of vaginoplasty in male-to-female sex reassignment surgery.

Labial masses following vaginoplasty in male transsexuals: the differential diagnosis

Following vaginoplasty and vulvoplasty for male-to-female transsexualism, a mass may evolve in one of the major labia in a minority of patients. From April of 1989 to April of 1994, we treated seven patients with such masses. The case reports presented illustrate some of the differential diagnoses of this long-term complication. More often than not, the swelling was caused by infection. The funiculus or even testicular rest in itself also may represent the mass. Intralabial urethral fistula appears to be the second cause of swelling, either with or without inflammation. As an exceptional cause we observed a swelling representing a cyst of prostatic origin. In all, the mass could be excised completely.
