Bibliometric analysis of research developments in oral and maxillofacial neuralgia from 2004 to 2023

This study employs bibliometric techniques to dynamically represent the research landscape of oral and maxillofacial neuralgia. Its goal is to pinpoint research hotspots and delineate forthcoming trends. A systematic search of the Web of Science Core Collection was performed using targeted keywords to retrieve literature from January 2004 to December 2023. Citespace version 6.2.6 was utilized to analyze countries, institutions, authors, co-cited journals, and keywords. The analysis indicates an annual increase in research literature on oral and maxillofacial neuralgia, albeit with a decline observed in the past 2 years. In the last 5 years, a total of 279 publications have been produced, predominantly by developed countries. The average betweenness centrality exceeds 0.1. Analysis of co-cited literature revealed 100 nodes, with research frontiers closely associated with trigeminal neuralgia, gamma knife radiosurgery, percutaneous balloon compression, among others. Keyword clustering analysis generated 61 nodes, primarily concentrated on 3 research areas: gamma knife, microvascular decompression, and hemifacial spasm. The emergence of keywords closely correlates with trigeminal neuralgia. Research frontiers in the field of oral and maxillofacial neuralgia are primarily focused on trigeminal neuralgia, with major therapeutic approaches including gamma knife radiosurgery and percutaneous balloon compression. These areas, along with botulinum toxin, represent current hotpots and are likely to drive the future direction of research in treating oral and maxillofacial neuralgia.
