A bibliometric and visualized research on global trends of scar, 2011-2021

Objective: Pathological scars are the results of abnormal wound healing, which not only affect the appearance, but may also be accompanied by significant psychosocial burdens. In this study, we aimed to conduct a bibliometric and visualized analysis on pathological scars and provide directions for future research. Methods: The articles on scar research from 2011 to 2021 in the Web of Science Core Collection database were collected. The bibliometrics records were retrieved and analyzed with Excel, CiteSpace V and VOSviewer.Results: A total of 944 scar research records published between 2011 and 2021 were col-lected. Publication output has shown an upward trend as a whole. China ranked first in terms of country contributions (418 publications, 5176 citations), while Germany, with only 22 studies published, had the highest average citation rate (57.18). Shanghai Jiaotong University was the institution with the largest number of related articles published, fol-lowed by the fourth military medical university, the University of Alberta and the Second military medical university. Wound repair and regeneration, Burns, Journal of Burn Care & Research, Journal of Cosmetic Dermatology published the most research in this field. Dahai Hu was the most prolific author, while Rei Ogawa was the most cited. The cluster analysis of the reference contributions and keywords indicated that current research hotspots mainly include pathogenesis, treatment strategies, and the safety evaluation of new scar treatment options. Conclusion: This study provides a comprehensive summary and analysis of the current status and research trends of pathological scars. International research interest in pathological scars is on the rise, and high-quality studies related to the field have also increased in the last decade. The pathogenesis of pathological scars, treatment strategies, such as fractional ablative CO2 laser and molecular targeted therapy, and the safety evaluation of new treatment options will be the focus of future research.(c) 2023 Elsevier Ltd and ISBI.
