Abstract

Background and Objectives: We evaluated if oxymetazoline therapy combined with 595-nm pulsed dye laser (PDL) will be more beneficial than topical oxymetazoline alone for the improvement of erythematotelangiectatic rosacea. Study Design/Materials and Methods: This was a randomized, controlled, prospective clinical trial approved by an independent Institutional Review Board, which enrolled 34 patients with moderate to severe clinical erythema (CEA) into a two-arm study of PDL with concomitant oxymetazoline cream (Arm 1) and oxymetazoline cream alone (Arm 2). Patients in Arm 1 were treated with 3 monthly laser sessions, which were started after 1 month of topical oxymetazoline cream. Thirty subjects continued with the study, and 25 subjects (Arm 1: 14, Arm 2: 11) completed the 6-month follow-up. With photographic comparison to baseline images, efficacy endpoints were based on clinical on-site grading by both the investigator and the patient, using the grading tools for CEA, Global Aesthetic Improvement (GAI) assessment, vessel size improvement, and subject self-assessment. These scales were assessed at baseline and/or at each clinical follow-up at 1, 2, 3, and 6 months. Subject satisfaction as well as post-treatment immediate response and treatment-associated pain scores were also evaluated. Results: Statistically significant improvement in CEA was seen in both arms at the 1-, 2-, and 3-month post-baseline visits (P < 0.01). Only Arm 1 presented statistically significant improvement in CEA (P < 0.001) at 6 months post baseline with a mean score of 1.6 (almost clear-mild) compared with 3.2 at baseline. Arm 1 showed significantly greater mean vessel size improvement at 3 months (P < 0.01) and 6 months (P < 0.05) post baseline compared to Arm 2. Significantly greater improvement (P < 0.05) in the investigator GAI score was reported at the 2- and 6-month follow-ups compared with Arm 2. Subject GAI scores showed statistically significant greater improvement in Arm 1 compared with Arm 2 at both the 3- and 6-month follow-ups (P < 0.01). There were no complications or long-term effects associated with PDL or topical oxymetazoline treatments. Conclusion: The prospective trial verifies a safe, enhanced clinical outcome with the combination of PDL therapy and topical oxymetazoline for the treatment of erythematotelangiectatic rosacea patients.
