The anterior neck scar outcomes of conventional thyroidectomy using a wound protector: a multicenter double-blinded randomized controlled trial.

PURPOSE:This study aimed to investigate the effectiveness of a novel wound protector in enhancing the cosmetic outcomes of thyroidectomy. MATERIAL AND METHODS:This multicenter, double-blinded randomized controlled trial enrolled 129 patients undergoing open thyroidectomy. The patients were divided into a wound protector group and a control group. Subjective patient assessments were conducted, measuring wound satisfaction, pain, and itchiness. Additionally, blinded observers evaluated scars using the Vancouver Scar Scale. RESULTS:The Vancouver Scar Scale revealed significant advantages for the wound protector group, demonstrating improvements in pigmentation (P=0.002), vascularity (P=0.014), pliability (P=0.001), and height (P=0.001). CONCLUSION:The thyroid wound protector offers a potential to improve post-operative cosmetic outcomes. Further research is warranted to explore patient experiences and optimize the application of this innovative wound protector across diverse surgical contexts.
