Publishing Trends in Otology and Neurotology.

OBJECTIVES: 1) Describe publishing trends for otologic/neurotologic disorders over a 35-year span. 2) Compare trends in publishing with disease prevalence. 3) Evaluate changes in topic and journal specific ranking scores over time.

METHODS: PubMed searches were performed on 35 otologic/neurotologic disorders using medical subject headings (MeSH) terms from 1980 to 2015. Searches were limited in scope to the English language. A Mann-Kendall trend analysis evaluated changes in publication frequency as a discrete variable while correcting for total number of articles published per year. Scopus was used to identify SCImago Country and Journal Rank (SJR) indicator scores and weighted-averages used to calculate changes over time.

RESULTS: The total number of publications on the 35 topics increased from 853 in 1980 to a peak of 3,068 in 2013. Otitis media (τ = -0.799, p < 0.001) and Menière's disease (τ = -0.724, p < 0.001) showed strong decreasing publication trends. Temporal bone encephaloceles (τ = 0.743, p < 0.001) and cochlear implants (τ = 0.740, p < 0.001) showed strong increasing publication trends. Rapid rise in publications on superior canal dehiscence and vestibular migraine illustrate novel diagnoses. The weighted-average SJR score increased from 0.816 in 2000 to 1.160 in 2015 (p < 0.001).

CONCLUSION: This study displays trends in the literature over the past 35 years that are often inconsistent with common disorders seen by otologists/neurotologists. Certain diagnoses that are currently being researched less commonly continue to impact patients with the same regularity. Quality of otologic/neurotologic literature has become more reputable with regards to SJR scores.
