Mapping the Evolving Trend and Prospect of Transoral Robotic Surgery: A Bibliometric Analysis

Abstract

OBJECTIVES: To conduct a comprehensive bibliometric analysis elucidating the global research landscape, collaborative networks, and evolving hotspots in transoral robotic surgery (TORS) from 2005 to 2024. MATERIALS AND METHODS: Publications related to TORS were retrieved from the Web of Science Core Collection database (2005-2024). In addition, the keyword "oropharyngeal cancer" was added to explore research hotspots. The data were primarily analyzed using bibliometric software based on publication date, country, authors, and keywords. RESULTS: A total of 1722 publications were initially analyzed, revealing a fluctuating upward trend that peaked at 177 publications in 2021. North America (led by the United States) and Europe dominated production, with Asia rising recently. Extensive collaboration involved 51 countries (11 clusters) and 7 author teams, spearheaded by pioneers Weinstein Gregory S. and O'Malley Bert W. Jr North American publications demonstrated the highest citation impact and journal influence. Keyword evolution shifted from surgical techniques (eg, minimally invasive surgery) to human papillomavirus (HPV), functional outcomes, and quality of life. A subanalysis of oropharyngeal cancer research (n=749 publications) confirmed these hotspots (HPV, outcomes, dysphagia) and highlighted regional disparities in research impact. CONCLUSIONS: This study systematically summarizes the current state of TORS and provides insights into global research priorities and future hotspots.
