title: Impact of Otolaryngology theses in their authors' scientific production.
abstract: OBJECTIVE
  The writing of a thesis has 2 main objectives: the appropriate training to be a good researcher and the publication of the first original research work. This study attempted to check this statement applied to theses in Otolaryngology by analysing the variation in the authors' publications.
  
  
  METHODS
  We used the database TESEO to obtain the data relative to Otolaryngology theses in Spain published between 1993 and 2003. We found the publications of each author by using de programme "Publish or Perish" and we analysed the variations in their work in 3 periods (prior to, around and after thesis publication).
  
  
  RESULTS
  The publications, the citations and the parameters analysed all increased in the second and third periods (around and after) with regard to the first period. However, there were no significant differences in some of them in the first 2 periods.
  
  
  CONCLUSIONS
  The elaboration of a thesis in Otolaryngology increased the scientific production of its author. Almost a third of the authors did not publish any work. There was a significant increase in all the parameters studied and the bibliometric indices between the period before thesis publication and the around and after thesis periods.
