Importance

Although applying adhesive strips to a wound closure has been shown to have outcomes equivalent to those with cuticular suturing, it is unknown whether adhesive strips provide additional benefit compared with dermal suturing alone.

Objective

To determine whether the addition of adhesive strips to a wound closed with buried interrupted subcuticular sutures improves outcomes following wound closure.

Design, setting, and participants

A prospective, randomized split-wound intervention was conducted between November 14, 2013, and May 16, 2014, in patients who underwent cutaneous surgical procedures at the University of California, Davis, outpatient dermatology clinic. Fifty-seven patients 18 years or older with postoperative defects of at least 3 cm, resulting from either Mohs micrographic surgical procedures or surgical excision, were screened for participation. Nine patients were excluded and 48 were enrolled.

Interventions

Half of each wound was randomized to receive buried interrupted subcuticular sutures and overlying adhesive strips and the other half received buried interrupted subcuticular sutures only.

Main outcomes and measures

At 3 months' follow-up, each patient and 2 blinded observers evaluated the wound using the Patient Observer Scar Assessment Scale.

Results

The total mean (SD) Patient Observer Scar Assessment Scale score for observers for the side that received a combination of adhesive strips and buried interrupted subcuticular suturing (12.3 [4.8]) and the side that received sutures only (12.9 [6.3]) did not differ significantly at 3 months (P = .32). There was no significant difference in the total patient assessment scale score between the combination closure (14.0 [7.6]) and sutures only (14.7 [7.6]) sides at 3 months (P = .39). There was also no significant difference between the 2 closure methods in terms of mean (SD) scar width (both methods: 1.1 [0.8] mm, P = .89) at follow-up.

Conclusions and relevance

Combination closure with adhesive strips and buried interrupted subcuticular suturing was not significantly associated with improved overall scar assessment compared with buried interrupted subcuticular suturing alone when evaluated by blinded observers or the patients themselves. Our results do not support the use of adhesive strips as a means to improve cosmetic outcomes or reduce scar width.
