Reduction clitoroplasty via ventral approach

Ventral clitoroplasty preserves dorsal nerves in case of partial androgen insensitivity syndrome: 4 years follow-up

Androgen insensitivity syndrome (AIS) causes feminization of the external genitalia, in 46XY individuals. We report a notable case of partial AIS (PAIS), which was treated with ventral clitoroplasty and vaginal dilatation. The patient is a 17-year-old phenotypically female, presented with primary amenorrhea, infantile vagina, clitoromegaly, and presence of testes. Feminizing genitoplasty was done in form of ventral clitoroplasty with gonadectomy and was put on hormone replacement therapy and advised regular use of vaginal dilators to improve vaginal length. In ventral approach, the erectile tissues are excised without disturbing the neurovascular structure. Vibratory threshold perception of clitoris assessed by biothesiometer was normal 4 years after the surgery. Vaginal corrective surgery is not required when presentation is at later stage and has some vaginal depth to work out with vaginal dilators. Regular psychiatric consultations and support are needed in patients with PAIS to develop their confidence in gender identity and sexual orientation.

Surgical Outcomes of Clitoroplasty in Children with Congenital Adrenal Hyperplasia and Clitoral Hypertrophy: A 19-Year Experience of a Single Surgeon

This study aimed to describe the experience with clitoroplasty for clitoral hypertrophy in patients with congenital adrenal hyperplasia of a single surgeon. The medical records of female pediatric patients with congenital adrenal hyperplasia who underwent clitoroplasty at a tertiary referral hospital between 2002 and 2020 were retrospectively analyzed. Three different surgical techniques were applied for clitoroplasty: recession without reduction, reduction and recession, and girth reduction and recession. A total of 104 patients underwent clitoroplasty for clitoral hypertrophy. The median patient age at the time of surgery was 10 months (range, 4 months to 10 years). The operation time was longer in reduction clitoroplasty than in recession clitoroplasty without reduction (median, 153 vs. 111 min, p = 0.003). The mean postoperative pain score of the patients did not differ among the different clitoroplasty techniques. During the mean follow-up of 37.7 months, nine (8.6%) patients underwent reperformed clitoroplasty. The rate of reperformed operation was significantly higher in patients who underwent reduction clitoroplasty (17.3%) than in those who underwent recession without reduction (2%) or girth reduction and recession (0%) (p = 0.031). Early clitoroplasty in patients with congenital adrenal hyperplasia yielded good mid-term surgical outcomes in terms of cosmesis and recurrence rate, with minimal perioperative complications.

Is nerve sparing clitoroplasty really a nerve sparing?

Background

Surgery for clitoral reduction has been practised for over half a century. The aim of clitoral surgery is to achieve normal clitoral morphology without compromising sexual function. To achieve these purposes, many techniques were developed since Young first reported reduction clitoroplasty in 1937. As the importance of the neurovascular bundle was realized, attempts were made to preserve this structure aiming at preservation of the sensory supply to the clitoris to achieve sexual satisfaction.

Methods

The study was conducted on six patients with congenital adrenal hyperplasia, who were operated upon with reduction clitoroplasty with neurovascular bundle preservation as a part of the genital reconstruction; surgery was done by single author (first author). Whole surgically removed corporal bodies were processed. Examination of the sections was done for the presence of nerve bundles related to the anatomical location of the neurovascular bundle using S100 immunohistochemical staining.

Results

In four cases, the presence of nerve fibers in the removed part of the corpus stained by S100 was high on the dorsal surface, with the presence of large nerve fibers (score 3–4), and low on the ventral surface with the presence of small nerve fibers (score 1). In the other two cases, it was low on both surfaces (score 1).

Conclusion

Subfacial clitoroplasty technique carries an inevitable risk of nerve injury and should be replaced by the subtunical technique.

Treatment of the Enlarged Clitoris

Management of the enlarged clitoris, because of its import for sexual function, has been and remains one of the most controversial topics in pediatric urology. Early controversy surrounding clitoroplasty resulted from many factors including an incomplete understanding of clitoral anatomy and incorrect assumptions of the role of the clitoris in sexual function. With a better understanding of anatomy and function, procedures have evolved to preserve clitoral tissue, especially with respect to the neurovascular bundles. These changes have been made in an effort to preserve clitoral sensation and preserve orgasmic potential. It is the goal of this manuscript to describe the different procedures that have been developed for the surgical management of clitoromegally, with emphasis on the risks and benefits of each. Equally important to any discussion of such a sensitive topic is an understanding of long-term patient outcomes. As we will see, despite its importance, there has been a dearth of data in this regard. Future work in the arena of patient satisfaction will undoubtedly play a major role in directing our surgical approach.

Nerve Sparing Ventral Clitoroplasty: Analysis of Clitoral Sensitivity and Viability

PURPOSE

Enlargement of the clitoris is often a prominent manifestation of virilizing congenital adrenal hyperplasia and other disorders of sexual development. Controversy persists regarding the viability and sensitivity of the clitoris following clitoroplasty. We present 51 consecutive cases of nerve sparing ventral clitoroplasty performed by a single surgeon.

MATERIALS AND METHODS

Nerve sparing ventral clitoroplasty was performed in all patients. Postoperative evaluation for clitoral viability included gross examination and capillary perfusion testing. Patients older than 5 years were evaluated for clitoral sensory testing and vibratory sensory testing.

RESULTS

A total of 51 patients 4 months to 24 years old (mean age +/- SD 4.6 +/- 6.8 years) with clitorimegaly underwent nerve sparing ventral clitoroplasty. Of the patients 41 had capillary perfusion testing of the clitoris, of whom all had a viable clitoris. Ten of the 41 patients underwent clitoral sensory testing. Patients reported an average degree of sensation of 3.6 +/- 0.9 at the labia minora and 4.8 +/- 0.4 at the clitoris. Nine of the 10 patients also underwent vibratory sensory testing. Average values for the introitus, clitoris, labia and thigh were 3.56, 1.61, 5.08, and 5.83, respectively. Mean time after surgery for the patients who underwent clitoral sensory testing/vibratory sensory testing was 2.0 +/- 0.8 years. No variations in the sensitivity results were reported at followup in 2 patients.

CONCLUSIONS

To our knowledge this is the largest report of followup testing of clitoral viability and sensation after clitoroplasty. Continued long-term followup is ongoing to document long-term sexual function using this nerve sparing ventral approach for clitoroplasty.

Clitoroplasty: past, present and future

This paper reviews the history of clitoral surgery throughout the twentieth century. The changing operations, from amputation through to attempts to produce a normal clitoris mirror the changing attitudes and available knowledge. It also examines the current issues that arise out of available data on long-term outcomes of clitoroplasty.

Anatomical studies of the female genitalia: surgical reconstructive implications

Surgery for patients with genital ambiguity must be based on an accurate diagnosis, thorough understanding of the genital anatomy and realistic expectations for the patient, family and treating multi-specialty team. The goal is to create a functional and cosmetic outcome consonant with the gender assignment with the least amount of morbidity to the patient and family. An understanding of the normal genital neuroanatomy is essential for a successful surgical approach and outcome. Based on fetal human specimens, we have refined the three-dimensional relationship of the dorsal nerve of the clitoris, the female cavernosal nerve and the vaginal plexus. The surgical approach to patients with severe clitoral virilization should preserve erectile function and the neural innervation of the clitoris. When indicated, surgery should be performed in infancy to minimize psychological trauma and surgical complications from scarring. Herein, we review the neuroanatomy of the female genitalia and the implications for the rare patient who needs surgical reconstruction.

The effect of clitoral surgery on sexual outcome in individuals who have intersex conditions with ambiguous genitalia: a cross-sectional study

BACKGROUND

The effects on sexual function of surgical removal of parts of the clitoris are unknown. For infants with intersex conditions and ambiguous genitalia being raised female, this surgery is often undertaken in early childhood. Our aim was to assess the effects of surgery on sexual outcome in this population.

METHOD

We did a cross-sectional study to which we recruited 39 adults who had intersex conditions with ambiguous genitalia who were living as female from clinical (n=15) and peer-support (n=24) settings. We obtained data by use of a postal questionnaire, incorporating a validated sexual function assessment inventory. We also obtained hospital notes of 36 respondents who did not want to remain anonymous, and did genital examinations of 19 women. We assessed sexual problems in relation to surgical history and compared the results for our population to those of a healthy control group.

FINDINGS

Of the 39 individuals enrolled, 28 had been sexually active and all had sexual difficulties. The 18 women who had undergone clitoral surgery had higher rates of non-sensuality (78%) and of inability to achieve orgasm (39%) than did the ten who had not had surgery (20% [p=0.002] and 0% [p=0.03], respectively).

INTERPRETATION

Sexual function could be compromised by clitoral surgery. Debate on the ethics of the use of this surgery in children should be promoted and further multicentre research is needed to ensure representative samples and comprehensive outcome assessment. Meanwhile, parents and patients who consent to clitoral surgery should be fully informed of the potential risks to sexual function.

Anatomical studies of the human clitoris

PURPOSE

Endogenous or exogenous testosterone exposure to the fetus during gestation may result in masculinization of the external genitalia. Surgical correction requires a clear understanding of normal female anatomy. We report observations from our anatomical dissections on which we base our approach to reduction clitoroplasty.

MATERIALS AND METHODS

A total of 14 normal human fetal clitoral specimens at 8 to 24 weeks of gestation were serially sectioned after formalin fixation. Every tenth section was stained with Masson's trichrome, smooth muscle alpha-actin and the neuronal markers PGP 9.5 or S-100. Computer reconstruction using imaging software permitted 3-dimensional analysis of the nerves, corporeal bodies and glans clitoris. These specimens were compared with 2 obtained postnatally at feminizing genitoplasty.

RESULTS

The normal fetal clitoris consists of 2 corporeal bodies with a midline septum. The ultrastructure of the female corporeal bodies is similar to that of the male counterpart. The glans clitoris forms a cap on top of the distal end of the narrowed corporeal bodies. There is a midline septum starting on the ventral aspect and extending approximately halfway into the glans. Large bundles of nerves course along the corporeal bodies with the highest density on the dorsal aspect or top. No nerves were noted at the 12 o'clock position, although nerves extend completely around the tunica in a fashion similar to that of the fetal penis. Glans innervation is provided by multiple perforating branches entering at the dorsal junction of the corporeal body and glans. The lowest density of nerves in the glans is on the ventral aspect in juxtaposition to the glans septum. In surgical specimens obtained from patients with congenital adrenal hyperplasia nerves were adjacent to the excised tunica of the corporeal bodies, especially on the lateral aspect.

CONCLUSIONS

A clear understanding of the anatomy of the human clitoris is important for surgical reconstruction. As in the human penis, nerves in the clitoris form an extensive network around the tunica of the corporeal body with a nerve-free zone at the midline 12 o'clock position. Care should be taken to preserve all nerves. Reduction of the glans clitoris should not violate the extensive innervation that predominates on the dorsal aspect of the glans. The normal clitoris has corporeal bodies that are smaller but analogous to those of the penis. One may consider their function when extensive resection is considered.

The surgical management of incomplete testicular feminization syndrome in three sisters

Three sisters with incomplete testicular feminization syndrome are presented. Most of the patients with this syndrome are females and surgery is an important part of their multidisciplinary treatment. Two of the sisters had gonadectomies, herniorrhaphies, vaginoplasty with neurovascular pudendal thigh flaps, reduction clitoroplasty and labia minora reconstruction. The third sister had sufficient vaginal depth and had release of an introitus skin web, clitoroplasty and labia minora reconstruction. All patients had a good result. The reconstructed vaginas are stable and sensate.

A new 1-stage procedure for clitorovaginoplasty in severely masculinized female pseudohermaphrodites

A new 1-stage procedure for clitorovaginoplasty in severely masculinized female pseudohermaphrodites is presented. The technique consists of clitoral reduction with preservation of the neurovascular supply to the glans and vaginal formation by joining the inverted penile skin and the divided distal "urethra" (urogenital sinus) to form a cylinder that is then inserted into the perineum and anastomosed to the true vagina. For high and small vaginas Monfort's transtrigonal approach is suggested. This operation, 4 of which have been performed to date, can be done at any age, and it offers excellent cosmetic and functional results.

Trends in conservative clitoroplasty

The authors present their trends in conservative clitoroplasty on the basis of 27 cases from January 1980 to August 1985. The technique described preserves as much of clitoral tissue as possible, and gives safe and very satisfying morpho-functional results regardless of the virilization degree. Preserved skin of clitoral shaft and of the foreskin is used to reconstruct labia minora. Erectile function is preserved by freeing and burying corpora cavernosa in the omolateral labial region. Clitoral glans, suitably trimmed when necessary, is preserved on its ventral muco-cutaneous pedicle.
