Identifying Core Journals in Otolaryngology: A Bibliometric Analysis

OBJECTIVES

As research in otolaryngology continues to expand rapidly, it is important to identify core journals to keep clinicians updated with the latest advances. This study is the first to characterize core journals in otolaryngology.

METHODS

Using h-index and impact factor (IF), the top 15 NLM-indexed otolaryngology journals were selected for analysis. The references from all articles published in these journals in one randomized quarter were compiled into a citation rank list, with the most cited journal ranked the highest. Citation zonal distribution analysis was conducted to identify the zonal distribution of otolaryngology journals.

RESULTS

A total of 3150 journals containing 26876 articles were cited in otolaryngology literature in April-June 2019. Laryngoscope was the most cited journal containing 1762 citations. IF is significantly associated with the h-index for the top 10 otolaryngology journals (p = 0.032). Three core journal zones were identified, with Zone 1 containing 8 journals, Zone 2 containing 36 journals, and Zone 3 containing 189 journals. A linear relationship between the log journal rank for Zones 1-3 and a cumulative number of citations was found (R2  = 0.9948).

CONCLUSION

Eight core journals for otolaryngology were identified: Laryngoscope, Otolaryngology-Head and Neck Surgery, Otology & Neurotology, JAMA Otolaryngology-Head & Neck Surgery, Head & Neck, European Archives of Oto-Rhino-Laryngology, International Journal of Pediatric Otorhinolaryngology, Annals of Otology, Rhinology & Laryngology. In the face of rapidly evolving research and a multitude of journals, the high citation density within these core journals highlights their utility in updating busy clinicians.
