Topical Adjuncts to Pulsed Dye Laser for Treatment of Port Wine Stains: Review of the Literature.
Review
Overview
abstract
BACKGROUND: Port wine stains (PWS) pose a therapeutic challenge. Pulsed dye laser (PDL) is the treatment of choice; however, treatment is often ineffective and recurrences are common. OBJECTIVE: This article provides a review of topical therapies that have been investigated to improve efficacy of PDL for the treatment of PWS. MATERIALS AND METHODS: A literature search was performed through PubMed, EMBASE, Web of Science, and CINAHL, using the search terms "port wine stain," "pulsed dye laser," and "topical." RESULTS: Clinical trials have investigated the topical agents, timolol, imiquimod, and rapamycin (RPM) in combination with PDL for the treatment of PWS. Topical timolol with PDL failed to show improved efficacy compared with PDL alone. Two clinical trials using imiquimod and PDL showed enhanced blanching of PWS compared with controls. Rapamycin and PDL were more effective than controls for facial PWS, but not for nonfacial PWS. CONCLUSION: Topical imiquimod and RPM have shown some efficacy in treating PWS with PDL, but to date there is no topical adjuvant to PDL that reliably improves results for PWS.
