Esthetic outcome of cleft lip repair with the use of tissue adhesive as opposed to suture for skin closure – A retrospective comparative study

Abstract

Background: Suture removal in infants and children operated for cleft lip is one of the cumbersome task for the surgeons because of missing compliance. For this reason, tissue adhesives have gained popularity among the surgeons as well as the patients over the past two decades for skin wound closure. Although there are several published reports of case series using tissue adhesive for skin closure during cleft lip repair, very few have established its advantage over conventional suture technique. Objective: The objective of this study was to compare the esthetic outcome of skin closure in cleft lip repair with suture technique and tissue adhesive, with respect to the quality of scar. Methodology: A retrospective observational study was conducted by analyzing the photographic records of patients who underwent surgical repair of cleft lip between January 2015 and December 2017. The patients were divided into two groups, one for whom skin closure performed with 5-0 monofilament polyamide suture and the other with tissue adhesive. Esthetic outcome in terms of the quality of scar was assessed using a 5 point Likert's scale by 10 independent observers who remained blind of the surgeon performed the surgery, to reduce the assessor-related bias to minimum. The statistical analysis was performed using the SPSS version 27.0 and the difference between mean scores of both the groups was calculated. Results: A total of 70 patients were included in this study with 35 in each group. The mean follow-up period of adhesive and the suture group was 13.97 and 17.85 months, respectively. Overall mean of the total scores of the entire patient population was 3.92 (+/‒0.38). For the tissue adhesive group, the mean score was 3.88 (+/‒0.367) and for the suture group, the mean score was 3.96 (+/‒0.401). The difference between mean scores of individual parameters of both the groups as well as the difference between the overall mean scores of both the groups was not found to be statistically significant. Conclusion: The use of tissue adhesive for the closure of skin during cleft lip repair is as good as sutures, with respect to esthetic outcome of scar. Hence, any of these two techniques can be used for this purpose depending on the surgeon's preference.
