The Cervical Scar Outcomes of Thyroidectomy Using a New Wound Protector: A Multicenter Double-Blinded Randomized Controlled Trial Woochul Kim Department of Medicine, General Surgery Graduate School Seoul National University Purpose: This study aimed to investigate the effectiveness of a novel wound protector in enhancing the wound 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. Objective assessment included the analysis of Vancouver Scar Scale scores collected by blinded observers as well as recording of drain amount and color. Results: Changes in the median scores for pain (p=0.318), itchiness (p=0.406), and overall satisfaction (p=0.715) did not show significant statistical difference between the protector group and the control group. The drain amount was higher in the control group with 59.8cc compared to 55.4cc in the protector group with a higher proportion of turbidity was seen in the control group. The median scores for sum of all items in the Vancouver Scar Scale at two weeks after operation was 4.049 for the protector group and 4.574 for the control group. At three months after operation, it was 1.934 for the protector group and 3.412 for the control group. It showed lower median scores in the protector group, indicating better scar outcomes. Changes in the median scores for pigmentation (p=0.002), vascularity (p=0.014), pliability (p=0.001), and height (p=0.001) was also shown to have significant statistical differences between the two groups. Conclusion: The thyroid wound protector offers potential to improve post-operative symptoms and cosmetic outcomes. Further research is warranted to explore patient experiences and optimize the application of this innovative wound protector across diverse surgical contexts.
