11.2 Anesthesia for Dermabrasion

The area to be dermabraded is cleaned with soap and water, 70% ethanol and painted with povidone iodine and at last, washed thoroughly with normal saline. It is anesthetized with use of eutectic mixture of local anesthetics (EMLA), infiltration anesthesia, nerve blocks and regional anesthesia. In extensive vitiligo, general anesthesia may be needed.

11.3 Mechanical Dermabrasion Tools

11.3.1 Dermabrader

The dermabrader consists of an electric hand engine with a high-speed rotary motor and an interchangeable abrading end piece (Figs. 11. 1 and 11. 2). The surgeon controls the speed with a foot pedal. Pressure exerted on the hand piece and the revolutions per minute of the hand piece are the two most important variables. Avoiding excessive pressure on the hand piece is important because this can result in gouging. Suggested rotational speeds of 12,000–15,000 rpm for the abrading heads result in controlled gradual planing of the treated surface.
