Three Decades of Research Trends in Rhinology: A Bibliometric Analysis of the Journal of Rhinology

BACKGROUND AND OBJECTIVES: This study conducted a comprehensive bibliometric analysis of articles published in the Journal of Rhinology (JR), the official journal of the Korean Rhinologic Society, to examine research trends, thematic evolution, and emerging hotspots in rhinology. METHODS: A total of 836 JR articles (1994-2025) were retrieved from PubMed and Research Information Sharing Service (RISS) after duplicate removal. The R bibliometrix package was used to perform keyword trend and thematic evolution analyses. VOSviewer was used to visualize keyword co-occurrence networks and temporal relationships between keywords. Gephi was used to calculate centrality measures, providing insight into the structural characteristics of the research network. RESULTS: From 1994 to 2025, JR published an average of 26.6 articles per year, with publication activity increasing in recent years. Keyword and thematic analyses demonstrated that the research focus gradually shifted from basic disease- and anatomy-related topics and traditional clinical themes in the 2010s to functional conditions, infectious diseases, and increasingly surgical, procedural, and methodological research after 2020, while "rhinitis" and "sleep apnea syndromes" were consistently addressed. Co-occurrence analysis further identified "endoscopy" as a central keyword, highlighting its continued importance in JR research. CONCLUSION: The articles published in JR encompass a broad spectrum of rhinology research, integrating disease pathophysiology, clinical applications, surgical techniques, and evidence-based approaches. These findings highlight evolving research trends and provide guidance for future domestic and international studies in rhinology.
