Dermabrasion
Dermabrasion
Kurtin presented the first large case series of patients demonstrating the efficacy of dermabrasion in 1955 with his cohort of 273 patients, some followed for up to 4 years after treatment.13 Despite the lack of a control group, his paper generated significant interest in the field of dermabrasion.
In 1987, Robinson studied the use of dermabrasion on a series of 192 full-thickness skin grafts to the nose, periorbital area, and ear.21 Half the group was randomized to receive dermabrasion at 18 months following surgery, while the control group used sun protection and topical lubricants only. Photographs were taken at 6, 18, and 24 months
after grafting and judged by the investigator after 5 years. Robinson found that grafts with elevated rims appeared to respond best to dermabrasion, whereas depressed grafts and hypertrophic scars in areas of full-thickness loss of skin and adnexal structures performed poorly. However, the scars in the dermabrasion group were no better than those in the control group.
Yarborough investigated the optimal time interval for dermabrasion treatment following wound injury.16 He abraded 97 facial scars 4 to 8 weeks following injury and 64 mature scars of 3 months to 13 yearsโ duration. He found 89% of scars abraded at 4 to 8 weeks showed no visible scarring at 6 months, while all scars in the mature scar group were all still apparent, even if modestly improved.
