Post-circumcision penile skin loss: reporting the outcome of one-stage anterolateral scrotal based flaps in children

Introduction

Improper penile assessment, together with carrying out circumcision by an inexperienced person, results in major complications. One of the complex complications is the complete or sub-complete penile skin loss, which in many cases, necessitates one or staged repair.

Purpose

To evaluate modified one-stage bilateral anterolateral scrotal-based flaps to compensate for penile skin loss after circumcision.

Methods

This study was performed on patients with almost penile skin loss after circumcision from February 2013 to July 2021. In all cases, one-stage modified bilateral anterolateral scrotal skin flaps were used to compensate for penile skin loss. The modification includes scrotal skin flap fashioning in a novel way, in addition to the use of penodermal fixation sutures at the penoscrotal junction, to create a stable penoscrotal junction and new penile skin coverage. Patients were discharged from the hospital on the same day of surgery. The dressing was left for 5 days. Follow-up visits were scheduled weekly in the first month, 3 and 6 months later, then annually.

Results

Forty-six children were included in this study. Their mean age was 4.5 ± 1.5 years. The mean operative time was 139.6 ± 11.5 min. No flap ischemia or necrosis was reported. One case (2.2%) developed a scrotal hematoma managed conservatively. Three (6.5%) cases presented with wound dehiscence at the penoscrotal angle. Three (6.5%) cases had self-limited penile edema. Two (4.3%) cases had dorsal midline hypertrophic scar; one improved after treatment with triamcinolone acetonide ointment, and the other needed scar revision. The mean follows up was 23.33 ± 9.13 months.

Conclusion

The modified scrotal skin flap technique provides a good substitution for stable penile skin coverage and a one-stage reconstruction of penile skin loss. It results in good parents' satisfaction with acceptable complications.

Normal penile, scrotal, and perineal anatomy with reconstructive considerations

A broad overview is provided of the normal anatomy of the male genitalia to offer the best surgical outcomes in cases related to congenital abnormalities, trauma, cancer-related extirpation, and aesthetics. Neural and vascular anatomy is discussed in depth due to its critical role in maintaining function and in assuring tissue viability.

Patient-reported complications and functional outcomes of male-to-female sex reassignment surgery

This study examined preoperative preparations, complications, and physical and functional outcomes of male-to-female sex reassignment surgery (SRS), based on reports by 232 patients, all of whom underwent penile-inversion vaginoplasty and sensate clitoroplasty, performed by one surgeon using a consistent technique. Nearly all patients discontinued hormone therapy before SRS and most reported that doing so created no difficulties. Preoperative electrolysis to remove genital hair, undergone by most patients, was not associated with less serious vaginal hair problems. No patients reported rectal-vaginal fistula or deep-vein thrombosis and reports of other significant surgical complications were uncommon. One third of patients, however, reported urinary stream problems. No single complication was significantly associated with regretting SRS. Satisfaction with most physical and functional outcomes of SRS was high; participants were least satisfied with vaginal lubrication, vaginal touch sensation, and vaginal erotic sensation. Frequency of achieving orgasm after SRS was not significantly associated with most general measures of satisfaction. Later years of surgery, reflecting greater surgeon experience, were not associated with lower prevalence rates for most complications or with better ratings for most physical and functional outcomes of SRS.

Measurement of sexual arousal in postoperative male-to-female transsexuals using vaginal photoplethysmography

Men's sexual arousal patterns are category-specific: Men typically display significantly greater physiological responses to sexual stimuli depicting members of their preferred gender category. Category-specific patterns of sexual arousal have not been consistently reported in natal women. We used vaginal photoplethysmography to examine patterns of sexual arousal in 11 male-to-female (MtF) transsexuals following sex reassignment surgery (SRS) and in 72 natal women. Subjective arousal was measured with a continuous response lever. Video clips depicting sexual activity between two males, two females, or one male and one female were used as erotic stimuli. All transsexual participants displayed category-specific sexual arousal. Five homosexual transsexual participants (attracted exclusively to males before sex reassignment) showed greater genital and subjective responses to male than to female stimuli, while six nonhomosexual transsexual participants showed the opposite pattern. Vaginal pulse amplitude (VPA) was lower in transsexual participants than in natal women. The mean correlation between VPA and subjective responses was high in nonhomosexual transsexuals, but was significantly lower in homosexual transsexuals and in natal women. One transsexual participant who reported a change in sexual orientation following sex reassignment displayed VPA and subjective responses consistent with her pre-reassignment sexual orientation. We conclude that male-to-female transsexuals display male-typical category-specific sexual arousal following SRS, and that vaginal photoplethysmography is a promising methodology for studying patterns of sexual arousal in postoperative transsexuals.
