Global Trends and Performances of Acupuncture Therapy on Bell's Palsy from 2000 to 2023 A Bibliometric Analysis

Purpose: Recent studies have shown that acupuncture may have great potential in the treatment of Bell's palsy. However, the bibliometric analysis of this field has not been summarized properly. Thus, the purpose of this study is to analyze the hotspot of acupuncture for Bell's Palsy. Methods: The core collection database of Web of Science was searched for relevant publications from 2000 to 2023, and countries, institutions, authors, keywords, and literature were analyzed and visualized by bibliometric softwareCiteSpace 5.1.R6, Vosviewer, BICOMB, and gCLUTO to explore the scientific achievements, research collaboration networks, research hot spots, and research trends. Results: 229 publications were included in this study. The most cited journal is Journal of Otolaryngology-Head & Neck Surgery; the most prolific country is China; the most prolific author is Li Ying, moreover, the collaboration among scholars is poor; Kyung Hee University is the most prolific institution studying acupuncture for Bell's Palsy. Reference burst detection indicates that traditional Chinese Medicine philosophy, the role of acupuncture in the prognosis of facial palsy, mechanism of acupuncture to improve facial nerve function, and the use of electroacupuncture are starting to become new research hotspots. Conclusion: The field of acupuncture for Bell's Palsy has developed rapidly in recent years, and new research trends are mainly: combination with traditional Chinese medicine, the role of acupuncture in the prognosis of facial palsy, mechanism of acupuncture to improve facial nerve function, and the use of electroacupuncture. However, research in this field is still dominated by case reports and clinical trials, and there is a lack of large-scale, multicenter clinical trials and animal experiments there are still many problems in institutional cooperation and experimental design, which requires relevant researchers to strengthen cooperation and improve experimental design.
