A Bibliometric Analysis of Publications on Tinnitus: A Study Based on Web of Science Data From 1980 to 2020

BACKGROUND: The incidence of tinnitus has been increasing together with its patient impact and societal costs. Much research has been conducted in the field of tinnitus, especially on treatment modalities because there still is no cure. This study aims to analyze the evolutions and developments in the scientific output relating to tinnitus. METHODS: We analyzed the Science Citation Index Expanded featured articles in the Web of Science Core Collection relating to tinnitus from 1980 to 2020. The publications were analyzed by characteristics such as the countries and institutions, journals, the most cited articles and references, and the most frequently used words in the abstracts and keywords. RESULTS: In total, 8282 articles relating to tinnitus were identified in the Web of Science. The number of publications has been significantly increasing after the 1990s. Of the 8282 articles, a major part originated from the American and European institutions. Most articles originated from high-impact journals, which consequently also covered the most cited papers. A major interest was seen in areas about treatment and pathogenic mechanisms. CONCLUSION: This bibliometric analysis here indicated an increasing trend in tinnitus research from 1980 to 2020, particularly with the increase in tinnitus burden and the societal costs by it. Specific interest has been seen in the specific tinnitus pathophysiological mechanisms and treatment. Individual researchers and institutions will gain a new perspective on their future studies based on the bibliometric data in our paper.
