Surgical Resection of Vulvar Labial Venous Malformations: A Single Center Experience

BACKGROUND

Venous malformations (VMs) involving the vulva are rare but often cause debilitating pain, aesthetic concern, and functional impairment. Treatment with medical therapy, sclerotherapy, operative resection, or a combination thereof may be considered. The optimal therapeutic approach remains unclear. We report our experience resecting labial VMs in a large cohort of patients.

METHODS

A retrospective review of patients who underwent partial or complete resection of a labial VM was conducted.

RESULTS

Thirty-one patients underwent forty-three resections of vulvar VMs between 1998 and 2022. Physical examination and imaging demonstrated: 16% of patients had focal labial lesions, 6% had multifocal labial lesions, and 77% had extensive labial lesions. Indications for intervention included pain (83%), appearance (21%), functional impairment (17%), bleeding (10%), and cellulitis (7%). Sixty-one percent of patients underwent a single resection, 13% multiple partial resections, and 26% a combination of sclerotherapy and operative resection(s). Median age was 16.3 years at first operation. All patients requiring multiple operations had extensive VMs. Median blood loss was 200 mL. Postoperative complications included wound infection/dehiscence (14%), hematoma (2%), and urinary tract infection (2%). The median follow-up assessment was 14 months: 88% of patients had no complaints and 3 patients were experiencing recurrent discomfort.

CONCLUSIONS

Surgical resection is a safe and effective approach to treating vulvar labial VMs. Patients with focal or multifocal VMs can be successfully treated with a single resection, whereas patients with an extensive VM may require multiple partial resections or combined sclerotherapy and resection(s) to achieve long-term control.

Surgical treatment of vulvar venous malformations without preoperative sclerotherapy: Outcomes of 18 patients

BACKGROUND

Our aim was to evaluate the benefit of surgical resection of the venous malformations (VMs) of the external female genitalia.

METHODS

Over the period of 2009-2019, 18 consecutive females underwent surgical resection for vulvar VM. Evaluations included preoperative Doppler ultrasound, MRI, and pre-and postoperative photographic imaging. The main outcomes were: residual pain, cosmetic distortion, residual VM, and quality of life.

RESULTS

Over a 10 year periods, 18 females, mean age 35 years (range 9-71) were included in this study. All patients were symptomatic: 16 had intermittent pain or discomfort, 1 had bleeding and 2 requested cosmetic treatment. Of these cases, there were 5 isolated vulvar VM, 12 associated VM: 3 of the clitoral hood, 3 troncular pelvic vein insufficiency and 12 of the lower limb. Eight patients had undergone previous procedures: 2 sclerotherapy treatments (1-3 sessions), 4 partial surgical resections. There were 18 single resections in the vulva (7 focal, 11 complete), 2 partial resections in clitoral hood and 2 had resection of a VM in the perirtoneovaginal canal at the same time. The mean follow-up was 42. 9 months (range 6-120). Two patients were lost to followup at 6 months. For all patients, elimination of pain and soft tissue redundancy was achieved. Two patients had persistent discomfort and 2 requested cosmetic treatment.

CONCLUSION

Surgical resection of vulvar VM can be the best approach with few postoperative complications, good functional and cosmetic results. Appropriate preoperative evaluation is required to identify isolated VM or VM associated with ovarian vein or internal iliac vein insufficiency requiring to be treated before surgery.

Do external female genital measurements affect genital perception and sexual function and orgasm?

Objective:

To provide baseline data for the anatomy of the external female genitalia and to investigate the correlation between those measurements and sexual function and genital perception.

Materials and Methods:

This prospective cohort study consisted of 208 healthy premenopausal women. The Female Sexual Function index (FSFI) and the Female Genital Self-image scale (FGSIS) questionnaires were administered. Participants were divided into two groups according to their female sexual dysfunction (FSD) status. External genital measurements and anterior and posterior vaginal length were measured.

Results:

The external female genital measurements were (cm, mean ± standard deviation): clitoral prepuce length 2.05±0.48; clitoral glans length 0.87±0.21; clitoral glans width 0.60±0.15; clitoris to urethra 2.24±0.55; anterior fornix depth 7.75±0.92; posterior fornix depth 9.25±0.75; labia minora width, right 2.12±0.86, left 2.20±0.96. A weak negative correlation was found between total FGSIS scores and clitoral prepuce length (p=0.01, r=-0.17), whereas a weak positive correlation was seen between total FGSIS scores and anterior-posterior vaginal lengths (p=0.04, r=0.13; p=0.02, r=0.15, respectively). No statistically significant difference was found between the genital measurements of participants with FSD (n=82, 39.4%) and those without FSD (n=126, 60.6%), and the total FSFI scores and orgasm subdomain scores.

Conclusion:

The female genital measurements were found to be distributed over a wide range. Although the relationship between genital measurements and genital perception varied, no significant relationship was found between genital measurements and sexual functions or orgasm. These findings suggest that a more cautious approach should be taken towards genital surgeries for cosmetic purposes.

Are anogenital distance and external female genitalia development changed in neural tube defects? Study in human fetuses

BACKGROUND

Anogenital distance (AGD), the distance from the anus to the genitals, is a marker of normal genital development. AGD and other biometric parameters of external female genitalia are important as ultrasonographic markers that can determine fetal gender in the first trimester. Neural tube defects are one of the commonest congenital malformations of the central nervous system, with anencephaly being the most severe defect. Female genitalia development and their association with anencephaly have not been previously described.

AIM

The aim of this study was to compare the biometric parameters of external female genitalia in fetuses with anencephaly and compare it to the parameters of normocephalic fetuses at different gestational ages.

STUDY DESIGN

We studied 34 female fetuses, 22 normocephalic and 12 anencephalic, aged between 12 and 22 weeks post-conception. The fetuses were placed in the classic lithotomy position and before the fetal dissection, the external female genitalia were photographed with a digital camera. Biometric parameters were recorded and measurements were performed using the Image J software, version 1.46r. Clitoral length and width, clitoris to anus distance, vaginal opening length and width, vaginal opening to labia majora distance, and AGD were measured (Figure). For statistical analysis, the Wilcoxon-Mann-Whitney test was used (p < 0.05).

RESULTS

We observed a significant difference between some measurements of the groups: the vaginal opening width was significantly greater in anencephalic fetuses and the vaginal opening length, clitoris to anus distance and vaginal opening to labia majora distance were significantly greater in normocephalic fetuses. For the clitoris length and width, we did not find statistical differences. We also did not find statistical significance in AGD between groups (normocephalic 2.32 mm [2.46-6.42/SD = 2.17] vs. anencephalic 3.93 mm [1.15-6.65/SD = 1.93]; p = 0.499). The linear regression analysis indicated that AGD increased more with age in anencephalic than in the normocephalic group, but without significant differences (r² = 0.01677; p < 0.318).

DISCUSSION

This article is the first to report the female external genitalia parameters in fetuses with anencephaly. In our study we observed some alterations in biometry of the external genitalia in anencephalic fetuses, with a pattern of morphological reduction in this group. The vaginal opening length, clitoris to anus distance and vaginal opening to labia majora distance were significantly lower in anencephalic fetuses but we did not find statistical significance in clitoris measurements and AGD.

CONCLUSIONS

Anencephalic fetuses had some alterations in external genitalia development, but the anogenital distances did vary significantly between the groups.

Appearance of external genital organs and types of hymen in Turkish female foetal cadavers

The present study's purpose was to determine the size and morphometric development of the female external genital organs on foetal cadavers. Dimensions of labia majora, labia minora and clitoris, bilabial diameter, vertical and horizontal diameters of hymenal opening, distance between the external urethral orifice and hymenal opening, distance between the clitoris and external urethral orifice and anogenital distance were measured. The hymenal types were determined. Mean values of parameters according to gestational weeks, months and trimesters were calculated. Imperforate hymen were determined in the first trimester. Twenty-eight foetuses with annular hymen, 25 foetuses with imperforate hymen, and 1 foetus with septated hymen were determined in the second trimester. Twenty-four foetuses with annular hymen, 3 foetuses with imperforate hymen, 1 foetus with fimbriated hymen, and 1 foetus with hymenal tag were determined in the third trimester. All foetuses in the full term were determined with annular hymen.

Normal vulvovaginal, perineal, and pelvic anatomy with reconstructive considerations

A thorough insight into the female genital anatomy is crucial for understanding and performing pelvic reconstructive procedures. The intimate relationship between the genitalia and the muscles, ligaments, and fascia that provide support is complex, but critical to restore during surgery for correction of prolapse or aesthetic reasons. The external female genitalia include the mons pubis, labia majora and minora, clitoris, vestibule with glands, perineal body, and the muscles and fascia surrounding these structures. Through the perineal membrane and the perineal body, these superficial vulvar structures are structurally related to the deep pelvic muscle levator ani with its fascia. The levator ani forms the pelvic floor with the coccygeus muscle and provides vital support to all the pelvic organs and stability to the perineum. The internal female genital organs include the vagina, cervix, uterus, tubes, and ovaries with their visceral fascia. The visceral fascia also called the endopelvic fascia, surrounds the pelvic organs and connects them to the pelvic walls. It is continuous with the paraurethral and paravaginal fascia, which is attached to the perineal membrane. Thus, the internal and external genitalia are closely related to the muscles and fascia, and work as one functioning unit.
