{Abstract}: <B>UNASSIGNED: </B>This study aims to identify determinants of high impact, measured by Impact Factor (IF) and Eigenfactor score, among otolaryngology journals.<BR><B>UNASSIGNED: </B>Bibliometric data of "otorhinolaryngology" journals were collected from the Journal Citation Reports (JCR) database. For the years 2009-2020, we collected normalized Eigenfactor score, 5-year IF, immediacy index, fraction of IF from journal-self citation, proportion and magnitude of published citable articles, and total citation counts. High-IF and -Eigenfactor journals were considered those within the top-quartile of that metric each respective year.<BR><B>UNASSIGNED: </B>High-IF and -Eigenfactor otolaryngology journals displayed higher 5-year IFs, immediacy indexes, and IF without self-citation (p < .05 for all years) including total citations counts and citable articles when ranked by Eigenfactor (p < .05 for all years). Otolaryngology IF correlated with 5-year IF and immediacy index within the same year (p < .05 for all years) and from previous years (p < .05 for all years; p < .05 for 2017-2018; p > .05 for 2009-2016). Eigenfactor correlated with 5-year IF, total citation counts, and citable articles within the same year (p < .05 for all years) and previous years (p < .05 for 2013-2018). Multilinear regression revealed that 5-year IF (p < .05 for 2009-2018) and immediacy index from the prior 2 years (p < .05 for 2017-2018; p > .05 for 2009-2016) predicted 2019 IF. Similarly, 5-year IF, total citation counts, and citable articles (p < .05 for 2013-2018) predicted 2019 Eigenfactor score.<BR><B>UNASSIGNED: </B>Sustained publication of impactful articles is the dominant driver of high IF and Eigenfactor score. Eigenfactor score reflects a unique evaluation of otolaryngology journals; ranking otolaryngology journals by their Eigenfactor scores significantly alters journal ranking compared to ranking by IF.<BR><B>UNASSIGNED: </B>NA.
