Erythematotelangiectatic Rosacea Clinical Trial
Official title:
Effects of Botulinum Toxin Type a Treatment on Clinical and Biophysical Parameters in Patients With Erythematotelangiectatic Rosacea: A Prospective, Randomized, Placebo-controlled, Double-masked Study
Investigation of the effectiveness of intradermal botulinum toxin A treatment in the treatment of erythematotelangiectatic rosacea (ETR) using clinical, biophysical, dermatoscopic and videocapillaroscopy.
There is no gold standard treatment for erythematotelangiectatic rosacea (ETR). In recent years, some studies have been conducted to demonstrate the efficacy of intradermal botulinum toxin A (BoNT-A) treatment in ETR and facial erythema. Studies including objective and quantitative measurements are limited. This study aims to investigate the efficacy and safety of intradermal BoNT-A treatment in ETR patients. This randomised, double-blind, split-face study included 30 participants with erythematotelangiectatic rosacea (ETR). They were randomly randomised to intradermal BoNT-A on one side of the face and placebo on the other side. Clinician's erythema assessment (CEA) score, patient self-assessment (PSA) score, erythema index (EI), melanin index (MI), dermatoscopic and capillaroscopic analyses of background erythema and vascular structure were assessed at baseline and one month after treatment. ;
