Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The MonaLisa Touch (MLT) procedure involves the superficial application of fractionated CO2 laser, to the vaginal mucosa by a specifically designed vaginal probe. The 5 minute treatment claims to 'rejuvenate' the mucosa and reverse postmenopausal vulvovaginal symptoms. Patients will receive the typical treatment course, which will consist of 3 treatments, each at least 4 weeks apart. These treatments will be performed by a suitably qualified gynaecologist.

Topical anaesthetic (2.5g of 4% lignocaine cream) will be applied the vulva for a minimum for 30 minutes. The treatment involves slow insertion of the vaginal probe into the vagina until it reaches the cervix or vaginal vault. The laser is set at dot power 40 watt, dwell time 1000 microseconds, dot spacing 1000 micrometres, smart stack parameter 2 and emission mode DP. The laser will then be activated as it is withdrawn to provide complete treatment of the vaginal walls. Energy is applied to vaginal walls in a pattern pre-determined by perforations in the probe matrix which covers the laser probe, allowing for even-spacing of energy and preventing treatment of confluent areas. Furthermore, a mirror at the end of the probe angled at 45 degrees protects the cervix from treatment. The duration of the procedure is anticipated to be approximately 5 minutes.

Adherence will be monitored by in-person attendance.

Treatment: Devices
Comparator / control treatment
The control group will undergo the same treatment setup as in the intervention group, including application of topical anaesthetic, insertion and incremental withdrawal of the probe down the vagina. For the placebo treatment, laser will be set at lowest energy settings of 0.5W, dwell time of 100 microseconds, spacing of 2000 micrometres, smart stack of 1 and emission mode smart pulse.
Control group
Placebo

Outcomes
Primary outcome [1] 298612 0
Visual analogue scale (VAS) score of the most severe postmenopausal vulvovaginal symptom- intensity of symptoms including vaginal burning, vaginal itching, vaginal dryness, dyspareunia and dysuria
Timepoint [1] 298612 0
At screening consultation, first treatment, second treatment (4 weeks after first), third treatment (8 weeks after first), follow-up consultation 3-months after last-treatment, and follow-up consultation 12-months after first-treatment.
Secondary outcome [1] 324762 0
Level of procedural pain/discomfort, assessed using a visual analogue scale.
Timepoint [1] 324762 0
After first treatment, second treatment (4 weeks after first treatment) and third treatment (8 weeks after first treatment).
Secondary outcome [2] 324763 0
Overall satisfaction with the procedure, assessed using a 5-point Likert scale.
Timepoint [2] 324763 0
At follow-up consultation, 3-months after final treatment.
Secondary outcome [3] 324764 0
Procedural complication rates, such as vaginal bleeding, infection, pain, and vaginal discharge.
These are reported by the patient to the practitioner, or the practitioner's observations.
Timepoint [3] 324764 0
After first treatment, second treatment (4 weeks after first treatment) and third treatment (8 weeks after first treatment).
Secondary outcome [4] 327814 0

Timepoint [4] 327814 0
Before and after treatment course
Secondary outcome [5] 327815 0
Vaginal Health Index Scores (VHIS) - based on vaginal elasticity, fluid volume, pH, epithelial integrity and moisture
Timepoint [5] 327815 0
At screening consultation, first treatment, second treatment, third treatment, follow-up consultation 3-months after last-treatment, and follow-up consultation 12-months after first-treatment.
Secondary outcome [6] 327816 0
Occurrence of adverse events since previous visit, assessed by symptom and scored on severity (mild, moderate, severe), noting treatment required (none, concomitant medication required, other), outcome (resolved, ongoing, other), duration (hours, days, weeks) and relationship to study (no relation to definite relation, or unknown).
Timepoint [6] 327816 0
At first treatment, second treatment, third treatment, follow-up consultation 3-months after last-treatment, and follow-up consultation 12-months after first-treatment.
Secondary outcome [7] 371670 0
Histological assessment of vaginal skin at baseline (taken on the right side of the vagina 3cm above the hymenal remnant) and repeated at the 6 monthly assessment on the left side of the vagina (3cm above the hymenal remnant) following the completion of the intervention by laser or placebo. Histological assessment will be completed in a blinded fashion by a suitably qualified histopathologist unaware of the group the woman is randomised to, or the order of the assessments (baseline or 6 months).
Timepoint [7] 371670 0
Baseline and 6 months

Eligibility
