The Research Trend of Non-surgical Rhinoplasty: A Bibliometric and Visualized Analysis.

Background: Rhinoplasty is one of the most common aesthetic surgeries, with non-surgical rhinoplasty (NSR) gaining popularity due to its affordability and minimal risks. The aim of this study is to use bibliometric analysis to identify prominent research areas and emerging trends within this field.

Methods: Research articles on NSR were gathered from the Web of Science Core Collection database. Following this, the analysis of co-authorships, keyword co-occurrences, and citation patterns involving countries, institutions, authors, and key journals was conducted using bibliometric tools VOSviewer and CiteSpace.

Results: In total, 197 documents related to research on NSR from the years 1900 to 2024 were retrieved. The USA led globally with 61 publications, with the University Of Verona contributing the highest number of articles (11). The journal Aesthetic Plastic Surgery was the most prominent in this specialty, having published 28 articles and Plastic and Reconstructive Surgery receiving the most frequent citations and co-citations. Bertossi D was the most productive author and the most co-cited author. The keywords most commonly associated with these studies, ranked by frequency, included "rhinoplasty," "hyaluronic acid" and "nose." Moreover, the issues related to complications from filler injections and the strategies for their prevention have attracted considerable interest.

Conclusion: This study provides a detailed overview of the primary trends in NSR research. Additionally, it highlights the critical need to enhance efforts to minimize complications associated with filler injections.
