Background:
Electrobrasion, like dermabrasion, is a method of surgical planing that is purported to improve postoperative scarring. Data regarding its benefits and harms relative to dermabrasion are absent.
Objective:
To compare the efficacy and potential harms of electrobrasion and dermabrasion.
Methods:
This was a pragmatic, randomized, double-blind, split-scar intervention in patients with suboptimal surgical outcomes. Half of the wound was randomized to treatment with dermabrasion and half to electrobrasion. At 3-month follow-up, both the patient and a blinded investigator evaluated the wound.
Results:
Electrobrasion and dermabrasion reduced the mean scores of the Manchester Scar Scale 1·6 and 1·3 points from baseline, respectively (P = 0·0003). The difference between treatments was not significant (P = 0·08). Global cosmetic improvement by physician and patient assessment indicated clinical improvement for both procedures but did not demonstrate statistical significance between treatments (P = 0·57, P = 0·32 for physician and patient, respectively).
Conclusions:
Both dermabrasion and electrobrasion improved scars, but there was no significant difference between the outcomes of the two procedures on several measures. Procedure time and bleeding time were significantly lower for electrobrasion.
