Objective: The objective of this study is to assess the usefulness of perineoplasty for introital stenosis related to vulvar lichen sclerosus. Study Design: The records of 64 patients who underwent perineoplasty for this indication were reviewed retrospectively. The median age of patients was 49 years, and the median duration of lichen sclerosus was 60 months. Ninety percent of patients complained of dyspareunia. Patient satisfaction with the outcome was assessed by means of a questionnaire. Persistence of dyspareunia and impaired quality of sexual intercourse were considered as treatment failure. Risk factors of failure that were evaluated included duration of lichen sclerosus, age, previous topical steroid therapy, previous perineotomy, time since surgery, and histologic stage. Statistical analysis was performed by use of Fisher exact test. Results: Of the 64 patients, 12 were lost to follow-up and 2 patients did not respond to the questionnaire. Perineoplasty improved dyspareunia in 45 of the 50 patients (90%) and quality of sexual intercourse in 43 of 50 patients (86%). None of the risk factors evaluated were associated with failure of perineoplasty. Conclusion: Perineoplasty provides good functional results for women with introital stenosis related to vulvar lichen sclerosus. (Am J Obstet Gynecol 2002;186:49-52.)
