EVOLUCIÓN DE LA PRODUCCIÓN CIENTÍFICA GENERADA SOBRE LA DEHISCENCIA DEL CANAL SEMICIRCULAR POSTERIOR.

Introduction: The dehiscence of the posterior semicircular canal is a rare vestibulopathy, of low prevalence and whose symptomatology is explained by the phenomenon of the third window. It was not until 2003 that Krombach described the first cases. Objective: Evaluate the scientific production about the dehiscence of the posterior semicircular canal (DCSP) by a bibliometric and thematic analysis and observes its incidence at the scientific community level. Method: A search with subsequent review, selection and study was carried out using items related to DCSP indexed in the Pubmed, Web of Science, Alcorze and Scopus databases, from 2003 to 2019, selecting a total of 90 articles. Results: The 90 articles have been published in a total of 48 magazines. 52% were originals, 38% clinical cases, 9% reviews and 1% conferences. Clinical (32%) and etiology (27%) were the main themes. The articles were written in eight different languages, predominantly English (85%), and the United States has been the country with the highest number of publications (42%). Institutional activity and authorship rates are low. The quality of the journals is high: 70% of the publications were in the Q1-Q2 quartiles. The main area corresponds to otorhinolaryngology, with a total of 66 works, followed by radiology (14). The total number of downloads was 6958, with an average of 77.31 per article and the total citations were 1193, 13.25 per article. Conclusions: The bibliometric results reveal how the works on dehiscence of the posterior semicircular canal present a small scientific production, the subject is in a phase of sustained growth, the authorship, institutional and collaboration index are low, the publications are concentrated in a few journals of high quality and important visualization, with a clearly anglophone orientation [ABSTRACT FROM AUTHOR]
