Clinical Trial to Demonstrate That the Dual Laser Therapy is Effective for the Treatment of Vulvar Lichen Sclerosus
Clinical Trial to Demonstrate That the Dual Laser Therapy is Effective for the Treatment of Vulvar Lichen Sclerosus
The aim of this study is to test a new, minimally invasive dual laser technique to treat
 vulvar lichen sclerosus. Efficacy and safety of the thermal non-ablative Nd:YAG laser and the
 ablative Er:YAG laser is determined and compared to the current standard treatment with high
 dose steroids. The hypothesis is that laser therapy is effective and similar to standard
 steroid therapy.
Lichen sclerosus (LS) is a chronic inflammatory skin disease that usually involves the
 anogenital area where it causes itching and burning pain, pain during sexual intercourse, and
 anal or genital bleeding due to fissuring of the damaged tissue. In this study a treatment
 with dual laser application combining thermal non-ablative Nd:YAG with ablative Er:YAG laser
 is used to reduce the symptoms of LS. Results will be compared to the standard therapy with
 topical steroid cream.
