Comparisonof 2-Octylcyanoacrylate Versus 5-0 Fast-Absorbing Gut During Linear Wound Closures and the Effect on Wound Cosmesis.

BACKGROUND
Although the use of 2-octylcyanoacrylate (OCA) in cutaneous surgery offers increased efficiency, there is scant data comparing scar outcomes achieved with OCA versus 5-0 fast-absorbing gut suture (FG).


OBJECTIVE
To compare scar cosmesis achieved with OCA versus FG for surgical wound closure.


MATERIALS AND METHODS
A total of 44 patients with postoperative defects of at least 3 cm were included. Half of each wound was randomized to receive closure with either OCA or FG. At 3 months, patients and 2 blinded observers evaluated each scar using the Patient and Observer Scar Assessment Scale (POSAS).


RESULTS
The total observer POSAS score (mean [SD]) for the side repaired with OCA (12.3 [4.72]) and the side that received FG (11.6 [4.36]) did not differ significantly (p = .40). There was no significant difference in the total patient POSAS scores between closure with OCA (14.9 [8.67]) and FG (14.6 [8.90]) (p = .70). Based on observer POSAS scores, scar pigmentation was significantly worse on the scar half repaired with OCA (1.98 [0.91]) compared with FG (1.79 [0.80]) (p = .05).


CONCLUSION
With the exception of inferior scar pigmentation with OCA, there was no statistically significant difference in wound cosmesis after linear wound closure with OCA versus FG.
