Objectives:
Reduction of postoperative scarring after unilateral cleft lip cheiloplasty is a pertinent topic. Smaller scar formation results not only in a better lip function, but also - aesthetics. This systematic review aims to identify various supplementary treatment options which influence favourable scarring outcome after cheiloplasty.
Material And Methods:
The systematic review was conducted following PRISMA guidelines and Cochrane methodologies, using databases including PubMed, ScienceDirect, The Cochrane Library, and Google Scholar. Articles published between 2012 and 2024 evaluating supplementary measures for reducing scar tissue post-unilateral cleft lip cheiloplasty were included. Studies were assessed for bias using the Joanna Briggs Institute Critical Appraisal Checklist, and outcomes were measured using Vancouver Scar Scale, Visual Analog Scale, Hollander Wound Evaluation Score, and scar width metrics.
Results:
Nine studies were analysed, highlighting platelet-rich plasma and botulinum toxin A as effective in reducing scar width and improving aesthetics. Silicone-based products enhanced wound healing, while non-absorbable sutures and tissue adhesives showed superior outcomes compared to absorbable sutures. Overall, supplementary measures significantly improved postoperative scar appearance.
Conclusions:
The use of platelet-rich plasma or botulinum toxin injections in musculus oribucalaris oris during the cheiloplasty significantly improves postoperative scar formation outcome. Wound edges approximation by non-absorbable sutures or tissue glue equally results in smaller scar formation and better aesthetic outcome. Suturing with absorbable sutures increases the incidence of complications and results in poor aesthetics. Postoperative wound care with products containing silicone significantly reduces scarring and aids in aesthetics.
