Surgical treatment of vulvar lichen sclerosus: a review.
Surgical therapy of lichen sclerosus of the vulva consists of three main operations: vulvectomy (with or without a skin graft), cryosurgery, and laser ablation. It is indicated in two conditions, either when malignant transformation is present or is likely to occur, or when medical treatment has failed. The overall risk for malignant transformation of vulvar lichen sclerosus is low, ranging between 0 and 9 percent. However, specific histological criteria, such as mixed dystrophy, have recently been associated with higher malignancy rates. Vulvectomy is indicated only when these criteria are met. Both skinning and simple vulvectomies are associated with recurrence rates as high as 50 percent. However, better sexual function and cosmetic results have been reported in the former, especially with concomitant split skin grafting. Cryosurgery also has high recurrence rates, although short-term results are favorable. Although only small series have been reported, laser therapy seems to carry better long-term results than other modes of treatment. Convalescence is complete within 6 weeks posttreatment, and remission rates are as high as 85 percent at 3 years of follow-up. The high recurrence rate of all surgical modalities makes surgical treatment suitable only for patients who failed to respond to multiple medical treatments such as topical high potent steroid ointments, testosterone, and retinoids.
