Abstract
BACKGROUND AND OBJECTIVES: Erythema is one of the most common cosmetic concerns and usually responds well to pulsed dye laser (PDL) treatment. As this laser can cause significant discomfort, topical anesthesia is sometimes offered. However, it is still uncertain whether topical anesthetics can affect the outcome of the laser therapy. We performed a retrospective single site study to compare the efficacy of PDL for the treatment of erythema in patients with and without pretreatment with topical anesthetic.
STUDY DESIGN/MATERIALS AND METHODS: A chart review was performed and patients who presented with erythema of face, neck, chest, and extremities pretreated with topical anesthesia (23% lidocaine/7% tetracaine ointment or 7% lidocaine/7% tetracaine ointment) undergoing PDL were reviewed and compared with another group without anesthesia. Two blinded dermatologists evaluated the postlaser procedure photographs and gave an assessment compared with baseline.
RESULTS: A total of 69 patient charts were reviewed. The erythema resulted from various skin conditions including telangiectasia, cherry angioma, striae, and rosacea. The mean improvement was 2.2581 in the anesthesia group and 2.2632 in the nonanesthesia group. There was no significant difference between both groups as confirmed by a noninferiority test.
CONCLUSIONS: Topical anesthesia with lidocaine and tetracaine ointment do not interfere with the efficacy of the PDL. Since pain management is essential for any cosmetic procedure, the application of a local anesthetic will enhance patient comfort and satisfaction during treatment with PDL. Lasers Surg.
