The Research Trend of Soft Tissue Filler Injection from 2000 to 2022: A Bibliometric and Visualized Analysis

The demand for soft tissue filler injections has experienced a significant increase in recent years. Therefore, this study used bibliometric analysis to identify prominent research areas and emerging trends within the field.

Publications concerning research on soft tissue filler injections were collected from the Web of Science Core Collection database. Subsequently, VOSviewer 1.6.18 and CiteSpace 6.2.R4 software were used to analyze the co-authorship, co-occurrence, and citations of countries, institutions, authors, hotspot keywords, and journals associated with these studies.

A total of 1370 records pertaining to filler injection research conducted between 2000 and 2022 were identified. The United States (524 publications) emerged as the country with the highest number of publications in this field, with Mayo Clinic (37 publications) making the most substantial contribution. Dermatologic Surgery emerged as the leading journal in this field, publishing the highest number of research articles (151 publications) and also being the most frequently co-cited. Cotofana proved to be the most prolific author with 51 publications, and Lemperle emerged as the most frequently co-cited author with 628 citations (including total link strength: 6587). The most popular keywords, in descending order of popularity, were "dermal filler," "injection," "soft-tissue augmentation," "complications," and "hyaluronic acid."

The findings of this study offer a comprehensive overview of the main directions in filler injection research. Furthermore, they underscore the imperative of intensifying efforts to prevent complications linked to filler injections.
