Aesthetic outcome of intermediate closure versus intermediate closure followed by 2-octyl cyanoacrylate: A randomized evaluator-blinded split-wound comparative effectiveness trial.

ABSTRACT

BACKGROUND: Dermatologic surgeons are increasingly using surgical adhesives in their practice. Studies comparing sutured wounds to those that utilize a combination of suturing and skin adhesive have not been previously conducted. OBJECTIVE: To compare the cosmetic outcome and patient wound care satisfaction of an intermediate suture closure with an intermediate suture closure followed by the application of 2-octyl cyanoacrylate (2-OCA). METHODS: Fifty patients were enrolled in a randomized, evaluator-blinded, split-scar study. Following intermediate sutured closure of a surgical defect, one side of the wound was randomized to receive an additional application of 2-OCA. After 3 months, the scar was assessed using the POSAS tool and patients reported wound care preferences. RESULTS: As the primary outcome measure, the mean sum of observer POSAS was 12.80 for sutured closure alone versus 12.40 for sutured closures followed by 2-OCA (P = .49). LIMITATIONS: Single-center study of a relatively homogenous population. CONCLUSION: Although there were no significant differences in scar cosmesis, both patients and observers tended to prefer the side with an additional application of 2-OCA in most POSAS components, in overall opinion, and in patient wound care satisfaction. Dermatologic surgeons may add this to their practice without sacrificing scar outcomes or patient satisfaction.
