Comparative Study Using Dermabrasion vs CO2 Laser & Collagen Dressing vs Vaseline Gauze in MKTP (MKTP)

February 22, 2017 updated by: Iltefat Hamzavi, Henry Ford Health System

Prospective Open Label Parallel Study Comparing Use of Carbon Dioxide Laser Versus Dermabrasion for Denuding Epithelium and Collagen Dressing Versus Vaseline Impregnated Gauze for the Melanocyte Keratinocyte Transplant Procedure

The purpose of this study is to:

  1. Compare two different techniques in the melanocyte keratinocyte transplant procedure: Use of carbon dioxide laser versus use of dermabrasion
  2. Compare two different dressings in the melanocyte keratinocyte transplant procedure: vaseline impregnated gauze versus collagen dressing

Study Overview

Detailed Description

The melanocyte keratinocyte transplant procedure (MKTP) has been shown to be effective in treating vitiligo and other conditions with depigmented skin. MKTP involves the transplantation of melanocytes and keratinocytes from normal skin onto the depigmented skin in order to repigment the skin.

Both dermabrasion and carbon dioxide lasers have been used effectively in MKTP to denude the epithelium. This study will compare the efficacy of these two techniques.

The study will also compare the efficacy of two different dressings used in MKTP, vaseline impregnated gauze and collagen dressings.
