Research involving animal models is crucial for the advancement of science, provided that experiments are designed, performed, interpreted, and reported well. In order to investigate the quality of reporting of articles in otorhinolaryngology research using animal models, a PubMed database search was conducted to retrieve eligible articles. The checklist of the ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines was used to assess the quality of reporting of articles published in ear, nose and throat (ENT) and multidisciplinary journals. Two authors screened titles, abstracts, and full texts to select articles reporting otorhinolaryngology research using in vivo animal models. ENT journals (n = 35) reported a mean of 57.1% adequately scored ARRIVE items (median: 58.3%; 95% confidence interval [CI; 53.4–60.9%]), while articles published in multidisciplinary journals (n = 36) reported a mean of 49.1% adequately scored items (median: 50.0; 95% CI [46.2–52.0%]). Articles published in ENT journals showed better quality of reporting of animal studies based on the ARRIVE guidelines (P < 0.05). However, adherence to the ARRIVE guidelines is generally poor in otorhinolaryngology research using in vivo animal models. The endorsement of the ARRIVE guidelines by authors, research and academic institutes, editorial offices and funding agencies is recommended for improved reporting of scientific research using animal models.
