OBJECTIVES/HYPOTHESIS: Evaluate the use of Twitter by otolaryngology journals and determine the relationship between social media altmetrics and measures of academic impact.
Cross-sectional analysis.
Twitter profiles from the top 50 otolaryngology journals per 2016 SCImago Journal & Country Rank (SJR) were included. Twitter activity for each profile was calculated using Twitonomy analytics and Riffle software. Social media influence was measured using Klout scores. Annual SJR rank and H-Index scores between 2008 and 2016 were recorded for each journal. Associations between social media influence and academic indices were assessed using Wilcoxon rank sum test, Spearman's rank order test, and Pearson correlation coefficients (α = .05).
Average SJR was 0.86 ± 0.3 and H-Index was 50.9 ± 24. Eighteen journals had Twitter profiles. Journals with social media accounts had significantly higher SJR (P = .03) and H-Index (P = .01) scores compared to those without. The average Klout score of Twitter profiles was 32.5 ± 13. There was a significant association between a journal's Klout score and SJR rank (P = .004). Older Twitter profiles had higher Klout scores (P = .04). There was a direct relationship between a journal's total Twitter followers and H-Index score (P = .009), and a direct relationship between tweets and academic influence (P = .03 and .01 for SJR and H-Index, respectively).
Social media is often underutilized and remains an untapped resource by many journals to increase readership and disseminate research. Journals with social media profiles had significantly higher academic metrics, and among journals with profiles, increased online activity was a predictor for academic influence. Future studies are warranted to elucidate causal relationships.

目的/假设：评估耳鼻咽喉科学期刊对推特的使用情况，并确定社交媒体替代计量指标与学术影响力衡量指标之间的关系。
横断面分析。
纳入2016年《Scimago期刊与国家排名》（SJR）中排名前50的耳鼻咽喉科学期刊的推特账号。使用Twitonomy分析软件和Riffle软件计算每个账号的推特活动情况。使用Klout评分衡量社交媒体影响力。记录各期刊在2008年至2016年期间的年度SJR排名和H指数得分。使用Wilcoxon秩和检验、Spearman等级顺序检验和Pearson相关系数评估社交媒体影响力与学术指标之间的关联（α = 0.05）。
平均SJR为0.86±0.3，H指数为50.9±24。18种期刊有推特账号。与没有社交媒体账号的期刊相比，有社交媒体账号的期刊SJR得分（P = 0.03）和H指数得分（P = 0.01）显著更高。推特账号的平均Klout评分为32.5±13。期刊的Klout评分与SJR排名之间存在显著关联（P = 0.004）。较老的推特账号Klout评分更高（P = 0.04）。期刊的推特总关注者数量与H指数得分之间存在直接关系（P = 0.009），推文与学术影响力之间存在直接关系（SJR和H指数的P值分别为0.03和0.01）。
社交媒体常常未得到充分利用，对许多期刊而言仍是一种未开发的资源，无法用于增加读者数量和传播研究成果。拥有社交媒体账号的期刊学术指标显著更高，在有账号的期刊中，网络活动增加是学术影响力的一个预测因素。未来有必要开展研究以阐明因果关系。
