Evaluation of the efficacy of fractional CO2 laser in the treatment of vulvar and vaginal menopausal symptoms

Fractional CO2 Laser for Vulvar Tissue Rejuvenation: A Prospective Study

Objective: Aging and changes in hormone levels influence the appearance of the vulva, including the texture, pigmentation, and other manifestations, all of which may largely affect the physical and mental health of women. This study aimed to evaluate the efficacy and safety of fractional carbon dioxide (CO2) laser treatment for vulvar rejuvenation in Chinese women. Background: The limited options currently available for vulvar rejuvenation raise concerns. There is insufficient evidence to determine whether the fractional CO2 laser can safely and effectively rejuvenate the vulvar area for women of various ages and races. Methods: The study included 17 patients (mean age = 36.4 years) treated three times by continuous fractional CO2 laser with an interval of 1 month between each session. The primary outcomes were changes in vulva texture and pigmentation. Treatment was evaluated using images of the patients. Baseline and posttreatment images were collected and evaluated using a scoring system from 0 to 3 to grade the vulvar texture and pigmentation changes. In addition, patients rated their degree of vaginal rejuvenation after the treatment using a scoring system from 0 to 3. Results: Fractional CO2 laser treatment effectively and significantly increased vulvar texture and decreased vulvar pigmentation after three sessions (p < 0.05). Patients also self-reported noticeable improvement. There were no adverse reactions during the treatment and follow-up. Conclusions: Fractional CO2 laser treatment is a safe and effective method for vulvar rejuvenation in women.

Nonestrogen Therapies for Treatment of Genitourinary Syndrome of Menopause: A Systematic Review

OBJECTIVE

To systematically review the literature and provide clinical practice guidelines regarding various nonestrogen therapies for treatment of genitourinary syndrome of menopause (GSM).

DATA SOURCES

MEDLINE, EMBASE, ClinicalTrials.gov , and Cochrane databases were searched from inception to July 2021. We included comparative and noncomparative studies. Interventions and comparators were limited to seven products that are commercially available and currently in use (vaginal dehydroepiandrosterone [DHEA], ospemifene, laser or energy-based therapies, polycarbophil-based vaginal moisturizer, Tibolone, vaginal hyaluronic acid, testosterone). Topical estrogen, placebo, other nonestrogen products, as well as no treatment were considered as comparators.

METHODS OF STUDY SELECTION

We double-screened 9,131 abstracts and identified 136 studies that met our criteria. Studies were assessed for quality and strength of evidence by the systematic review group.

TABULATION, INTEGRATION, AND RESULTS

Information regarding the participants, details on the intervention and comparator and outcomes were extracted from the eligible studies. Alternative therapies were similar or superior to estrogen or placebo with minimal increase in adverse events. Dose response was noted with vaginal DHEA and testosterone. Vaginal DHEA, ospemifene, erbium and fractional carbon dioxide (CO 2 ) laser, polycarbophil-based vaginal moisturizer, tibolone, hyaluronic acid, and testosterone all improved subjective and objective signs of atrophy. Vaginal DHEA, ospemifene, tibolone, fractional CO 2 laser, polycarbophil-based vaginal moisturizer, and testosterone improved sexual function.

CONCLUSION

Most nonestrogen therapies are effective treatments for the various symptoms of GSM. There are insufficient data to compare nonestrogen options to each other.

Safety and efficacy of fractional CO2 laser treatment to the vestibule: a randomized, double-blind, sham-controlled, prospective 3-site clinical study in women with vestibular pain

BACKGROUND

Data are limited regarding fractional CO2 laser as a nonhormonal treatment for vestibular pain.

AIM

We sought to perform what is, to our knowledge, the first multisite prospective randomized, double-blind, sham-controlled clinical trial to assess the safety and efficacy of fractional CO2 laser treatment to the vestibule in women with vestibular pain.

METHODS

Subjects (n = 70) meeting inclusion/exclusion criteria at each of 3 sites were randomized 2:1 to active or sham (zero energy) fractional CO2 laser treatment using the vestibular probe (SmartXide2 V2LR - MonaLisa Touch, DEKA, Florence, Italy). Subjects in each treatment arm received 3 treatments 4 weeks apart. At the initial follow-up (week 12), subjects were unblinded and those initially assigned to sham started active treatment.

OUTCOMES

Outcome measures included changes from baseline in sexual activity diaries and scores for the Vulvoscopic Genital Tissue Appearance Scale (VGTA), vestibular cotton-tipped swab testing, McGill Pain Questionnaire, Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), and the O'Leary-Sant voiding and pain indices, the Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI).

RESULTS

After active treatment, VGTA scores significantly improved in 5 parameters. Pain associated with cotton-tipped swab testing was significantly reduced at weeks 4 through 16 (mean change from baseline -0.64 [95% CI, -0.79 to -0.50] and -1.31 [95% CI, -1.46 to -1.16], respectively). FSFI pain domain scores improved significantly at weeks 12 and 16 (mean change from baseline 0.925 [95% CI, 0.10-1.75] and 1.22 [95% CI, 0.40-2.05], respectively). FSFI total scores increased significantly at weeks 12 and 16 (mean change from baseline 6.24 [95% CI, 2.64-9.85] and 4.96 [95% CI, 1.36-8.57], respectively). FSDS-R scores decreased significantly at weeks 12 and 16 (mean change from baseline -5.84 [95% CI, -8.80 to -2.87] and -9.15 [95% CI, -12.11 to -6.18], respectively). ICSI scores decreased significantly at weeks 12 and 16 (mean change from baseline -0.91 [95% CI, -1.65 to -0.18] and -0.754 [95% CI, -1.49 to -0.02], respectively). ICPI scores decreased significantly at week 16 (mean change from baseline -0.99 [95% CI, -1.63 to -0.34]). In contrast, there were no significant changes in outcomes in the sham arm. No serious adverse events occurred.

CLINICAL IMPLICATIONS

Fractional CO2 laser treatment in women with vestibular pain resulted in improvement from baseline in multiple key outcome measures of vestibular health.

STRENGTHS AND LIMITATIONS

Strengths of the study were that it was a multisite prospective randomized double-blind, sham-controlled clinical trial that included multiple measures related to vestibular pain and sexual function. Limitations were the nonvalidated primary outcome measure and limited study cohort.

CONCLUSION

Fractional CO2 laser therapy is a safe and effective nonhormonal treatment for vestibular pain.

New Innovations for the Treatment of Vulvovaginal Atrophy: An Up-to-Date Review

Vulvovaginal atrophy (VVA) is a chronic progressive disease involving the female genital apparatus and lower urinary tract. This condition is related to hypoestrogenism consequent to menopause onset but is also due to the hormonal decrease after adjuvant therapy for patients affected by breast cancer. Considering the high prevalence of VVA and the expected growth of this condition due to the increase in the average age of the female population, it is easy to understand its significant social impact. VVA causes uncomfortable disorders, such as vaginal dryness, itching, burning, and dyspareunia, and requires constant treatment, on cessation of which symptoms tend to reappear. The currently available therapies include vaginal lubricants and moisturizers, vaginal estrogens and dehydroepiandrosterone (DHEA), systemic hormone therapy, and Ospemifene. Considering, however, that such therapies have some problems that include contraindications, ineffectiveness, and low compliance, finding an innovative, effective, and safe treatment is crucial. The present data suggest great efficacy and safety of a vaginal laser in the treatment of genital symptoms and improvement in sexual function in patients affected by VVA. The beneficial effect tends to be sustained over the long-term, and no serious adverse events have been identified. The aim of this review is to report up-to-date efficacy and safety data of laser energy devices, in particular the microablative fractional carbon dioxide laser and the non-ablative photothermal Erbium-YAG laser.

The evidence behind the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus: A state-of-the-art review

In recent years, LASER has been introduced as a minimally invasive treatment for a broad range of vaginal and vulvar symptoms and diseases. However, the efficacy and safety of vaginal and vulvar LASER has continuously been questioned. The aim of this study is to create an overview of the current literature and discuss the controversies within the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus. A search string was built in PubMed. The search was commenced on August 25, 2021 and closed on October 27, 2021. Two authors screened the studies in Covidence for inclusion according to the eligibility criteria in the protocol. The data were extracted from the studies and are reported in both text and tables. This review included 114 papers, of which 15 were randomized controlled trials (RCTs). The effect of LASER as a vaginal treatment was investigated for genitourinary syndrome of menopause in 36 studies (six RCTs), vulvovaginal atrophy in 34 studies (four RCTs) and urinary incontinence in 30 studies (two RCTs). Ten studies (three RCTs) investigated the effect of vulvar treatment for lichen sclerosus. Half of the included RCTs, irrespective of indication, did not find a significant difference in improvement in women treated with vaginal CO₂ or Er:YAG LASER compared with their respective controls. However, most non-comparative studies reported significant improvement after exposure to vaginal or vulvar LASER across all indications. Included studies generally had a short follow-up period and only a single RCT followed their participants for more than 6 months post treatment. Adverse events were reported as mild and transient and 99 studies including 51 094 patients provided information of no serious adverse events. In conclusion, this review found that the effect of vaginal and vulvar LASER decreases with higher study quality where potential biases have been eliminated. We therefore stress that all patients who are treated with vaginal or vulvar LASER should be carefully monitored and that LASER for those indications as a treatment should be kept on a research level until further high-quality evidence is available.

Treatment of Vulvovaginal Atrophy with Fractional CO2 Laser: Evaluating Real-World Data

Objective: We aimed to evaluate real-world data for the use of fractional CO₂ laser therapy for treating symptoms of vulvovaginal atrophy (VVA). Background: VVA is widespread and can reduce the patients' quality of life. There is a lack of data regarding its therapy with laser, especially for daily practice (i.e., real-world data). Methods: Thirty-six patients were treated in a single medical center. They consisted of pre- and postmenopausal women and received three fractional CO₂ laser therapy treatments with 3-6 weeks between each treatment. Each patient financed the treatment privately. The symptoms pain, pruritus, dyspareunia, burning, dryness, and dysuria were recorded with a visual analog scale (1-10) before the first, second, and third laser treatment. The data were examined retrospectively. Results: Pain was reduced from a mean of 2.5 points (minimum 0, maximum 9 points) to 1.1 (minimum 0, maximum 8 points) before the third laser treatment. Pruritus showed a mean score of 3.8 (minimum 0, maximum 10 points). This decreased to 1.4 (minimum 0, maximum 8 points). Dyspareunia scored a mean of 6.8 (minimum 0, maximum 10 points). After two laser therapies, the score was 3.3 (minimum 0, maximum 8 points). Burning showed 4.2 points (minimum 0, maximum 10 points). Having experienced two laser therapy sessions, the patients scored 1.5 (minimum 0, maximum 9 points) points. The severity of dryness dropped from 6.5 (minimum 0, maximum 10 points) to 3.3 (minimum 0, maximum 9 points). Dysuria was stated with 1.8 points (minimum 0, maximum 10 points) before the first and 0.5 points (minimum 0, maximum 6 points) before the third laser therapy. All changes showed statistical significance (p < 0.002). Conclusions: This real-world data propose fractional CO₂ laser to reduce VVA-associated genital discomfort, thus being a valuable therapy option for pre- and postmenopausal women.

Carbon Dioxide Laser Vulvovaginal Rejuvenation: A Systematic Review

Genitourinary syndrome of menopause (GSM) causes significant symptomatic aggravation that affects the quality of life (QoL). Vulvovaginal atrophy (VVA), the hallmark of GSM, is managed with topical non-hormonal therapy, including moisturizers and lubricants, and topical estrogen application. Patients not responding/being unsatisfied with previous local estrogen therapies are candidates for a noninvasive modality. Carbon dioxide (CO2) laser therapy, especially the fractionated type (FrCO2), has drawn considerable attention over the past two decades as a non-invasive treatment for GSM. This systematic review describes the accumulated evidence from 40 FrCO2 laser studies (3466 participants) in GSM/VVA. MEDLINE, Scopus and Cochrane databases were searched through April 2021. We analyze the effects of FrCO2 laser therapy on symptoms, sexual function, and QoL of patients with GSM/VVA. As shown in this review, FrCO2 laser therapy for GSM shows good efficacy and safety. This modality has the potential to advance female sexual wellness. Patient satisfaction was high in the studies included in this systematic review. However, there is a lack of level I evidence, and more randomized sham-controlled trials are required. Furthermore, several clinical questions, such as the number of sessions required that determine cost-effectiveness, should be addressed. Also, whether FrCO2 laser therapy may exert a synergistic effect with systemic and/or local hormonal/non-hormonal treatments, energy-based devices, and other modalities to treat GMS requires further investigation. Lastly, studies are required to compare FrCO2 laser therapy with other energy-based devices such as erbium:YAG laser and radiofrequency.

Vaginal laser therapy for genitourinary syndrome of menopause - systematic review

BACKGROUND

Genitourinary syndrome of menopause (GSM) can have a great impact on the quality of life (QOL), and affects between 53.8% and 90% of postmenopausal women. The literature suggests that vaginal laser therapy could be an effective treatment for GSM symptoms, but its efficacy and safety have not been established and international societies do not endorse its use. Despite that, there has been an increase in the use of vaginal laser therapy globally over the last decade.

OBJECTIVE

The objective of this review is to evaluate the literature which assesses the efficacy and safety of the vaginal laser therapy in the treatment of GSM.

METHODS

A comprehensive literature search was conducted electronically using Embase and PubMed to retrieve studies assessing evidence for the efficacy and safety of vaginal laser therapy for GSM or vulvovaginal atrophy up to June 2021.

RESULTS

A total of 64 studies were finally included in the review. There were 10 controlled intervention studies, 7 observational cohort and cross-sectional studies and 47 before-after studies without a control group.

CONCLUSION

Vaginal laser seems to improve scores on the Visual Analogue Scale (VAS), Female Sexual Function Index (FSFI) and Vaginal Health Index (VHI) in GSM over the short term. Safety outcomes are underreported and short-term. Further well-designed clinical trials with sham-laser control groups and evaluating objective variables are needed to provide the best evidence on efficacy.
