BackgroundWound edge eversion has been hypothesized to improve aesthetic outcomes after cutaneous wound closure. Data supporting this assertion are sparse.ObjectiveWe sought to determine if wound eversion, achieved with interrupted subcuticular sutures, improves aesthetic outcome compared with planar closures.MethodsWe undertook a prospective, randomized, split-scar intervention in patients who underwent cutaneous surgery. Half of the wound was randomized to an everted or planar repair; the other side received the opposite one. At 3- and 6-month follow-up, both the patient and 2 blinded observers evaluated the wound using the Patient Observer Self-Assessment Scale (POSAS).ResultsThe total observer POSAS score for the everted (13.59, 12.26) and planar (12.91, 12.98) sides did not differ significantly at 3 or 6 months, respectively. Similarly, there was not a significant difference in patient assessment between the everted (16.23, 12.84) and planar (15.07, 12.79) sides at 3 or 6 months, respectively. Finally, there was no significant difference between the 2 closure methods in terms of scar height or width at follow-up.LimitationsThis was a single-center trial, which used a validated but still subjective scar assessment instrument.ConclusionWound eversion was not significantly associated with improved overall scar assessments by blinded observers or patient assessment
