The Hirsch (h) index is an original and simple new bibliometric measure incorporating both quantity and quality. In this study, our aim was first to present characteristics of the statistical correlation between the h index and several standard bibliometric indicators and secondly we compared the h index between otolaryngologists from Europe and US. We used the Institute of Scientific Information (ISI) Web of Knowledge to identify citation reports from a random sample of influential editors from six otolaryngology journals: Journal of Laryngology and Otology (n = 21), Clinical Otolaryngology (n = 16), European Archives of Oto-Rhino-Laryngology (n = 49), The Laryngoscope (n = 66), Otolaryngology-Head and Neck Surgery (n = 15), and Archives of Otolaryngology-Head and Neck Surgery (n = 15). The following data were gathered: Number of publications (P), total citations received by P(C), total citations received by P without self-citations (Cs), average number of citations per publication (CPP), and Hirsch index (h). Statistical analysis was used to correlate the above data and we also compared the h index of European and North American editors. There were 182 randomly selected editors. We observed a good correlation between the h index and other standard bibliometric indicators. Using the non-parametric Mann–Whitney test, the median P between Europe and US was not statistically significant. However, the median C, CS and h were statistically significant. In conclusion, the h index is a simple yet powerful indicator as it combines productivity and impact. Overall, the US editorial panel have a higher h index.
