Evaluation of Cosmetic Outcome of Running Subcuticular Sutures Over Simple Interrupted Sutures in Linear Facial Lacerations

Abstract

Background: Facial lacerations are a common cause of presentation in the Emergency Room. The technique applied to close these lacerations may influence the aesthetic outcome of the scar formed. Our research objective was to compare the two most commonly used Running Subcuticular Sutures (RSS) or Simple Interrupted Sutures (SIS) techniques in terms of the aesthetic outcome of the resulting scar. Methods: This randomized controlled trial was conducted at Jinnah Hospital, Lahore, from January to June 2023 using a consecutive sampling technique. A total of 92 patients of both genders aged between 18 and 65 presenting in the Emergency Room with linear facial lacerations were assigned randomly to receive either RSS or SIS for closure of facial lacerations. The primary outcome was cosmetic results measured by the score on the Patient and Observer Scar Assessment Scale (POSAS) 6 weeks after treatment along with a 4-point scale score and rate of complication. The outcome statistics were analyzed using SPSS. Results: The RSS group had a mean Patient Scar Assessment Scale (PSAS) score of 9.0 and Observer Scar Assessment Scale (OSAS) score of 10.3 while SIS had a mean PSAS score of 9.8 and OSAS score of 11.7. Statistical analysis revealed that the two groups had no significant difference in cosmetic outcome (P-values 0.31 & 0.17). The rate of complications was also similar. Conclusion: The study highlights that the SIS technique does not have clinical superiority over RSS in terms of scar cosmesis or risk of complication and that both techniques can be used interchangeably.
