Microneedling on the external female genitalia's flaccidity in patients with Ehlers-Danlos: Case report

Comparative effects of fractional radiofrequency and microneedling on the genitalia of postmenopausal women: Histological and clinical changes

OBJECTIVES

The authors aimed to evaluate clinical and histological changes induced by Fractional Radiofrequency (FRF) and microneedling in vulvar tissue.

METHODS

Thirty postmenopausal women were randomly divided into G1 (FRF) and G2 (microneedling) groups. Sub-ablative FRF was executed using disposable fractionated electrodes with an intensity of 8 mJ. Microneedling was performed using a derma roller system. The authors evaluated before and after treatment using the Vaginal Laxity Questionnaire (VLQ), EuroQol Five-Dimensional (EQ-5D) questionnaire, and the Blatt and Kupperman Menopausal Index (BKMI). Additionally, the authors performed biopsies of the labia majora for histological analysis pre- and post-treatment. Data were expressed as mean (± standard deviation). A paired t-test was used for intra-group comparison (pre- and post-treatment), with an independent t-test used to compare intergroup data (both pre- and post-treatment).

RESULTS

In the G1 group, the VLQ values showed differences compared to the pre-treatment values with the data obtained 60 days after the beginning of the sessions (p = 0.01). Similarly, the data changes of the G2 group proved to be significant (p = 0.001) across the same time interval. In comparing the groups, VLQ values were not different (p > 0.05). Regarding histological analysis, FRF demonstrated improvement concerning the number of fibroblasts, blood vessels, and fatty degeneration (p < 0.05) compared to the control. Additionally, FRF and microneedling samples showed higher type III collagen and vimentin expression in the immunohistochemical analysis (p < 0.05).

CONCLUSIONS

The therapies were found to be effective in treating the flaccidity of the female external genitalia. Additionally, histological changes were observed after interventions suggesting collagen remodeling.

A Standardized Evaluation Method for Assessing Patients With Genital Dyschromia

Objective

The population's ever-growing concern with genital aesthetic dysfunctions reflects an increasing demand in the field of intimate aesthetics. For this reason, as well as the lack of a standardized evaluation, this paper aims to develop a form that facilitates the initial investigation of aesthetic genital dysfunctions. 

Methods

An evaluation form for female and male genital dyschromia was developed between July and November 2018. Following initial development, the form was evaluated for quality and was updated by a panel of specialists (a psychologist, two pelvic dysfunction physiotherapists, and two dermato-functional physiotherapists) via email and through a content validity questionnaire. The face validity of the form was assessed by five physiotherapy and medical students who were randomly selected. The students answered a questionnaire evaluating the proposed form. The reliability of the form was established through the test-retest procedure by evaluating its reproducibility over time.

Results

The “Genital Dyschromia Evaluation Form'' (composed of identification, anamnesis, and physical examination sections) was approved by the specialist panel. They suggested questions to be added in the anamnesis (dermatological lesions or fungal and bacterial infections) and physical examination (hyperemia, edema in the perianal and internal thigh region) sections. As for the image analysis, an increase in quality, resolution, and sharpness was suggested. Lastly, for the cutaneous phototype evaluation, the DoctorSkinFototipo® digital analyzer device was chosen since it is small, portable, easily positioned on the genital area, and can be readily cleaned between patients. 

Conclusion

The “Genital Dyschromia Evaluation Form” is a questionnaire approved by specialists and could represent a suitable option for health professionals.
