title: [Potential risk factors of excessive epistaxis after endoscopic endonasal surgery].
abstract: OBJECTIVE
  To investigate the potential risk factors and management of excessive epistaxis after endoscopic endonasal surgery (EES).
  
  
  METHODS
  Six hundred and forty-one patients who underwent EES in our hospital from December 2011 to December 2012 were reviewed retrospectively. Factors which potentially affect the incidence of excessive epistaxis after EES were analyzed with univariate and multivariate logistic regression model.
  
  
  RESULTS
  The incidence rate of excessive epistaxis after EES was 8.4% in our study. Multivariate logistic regression analysis revealed that history of previous EES, along with other four factors, correlated significantly with the occurrence of excessive epistaxis after EES.
  
  
  CONCLUSIONS
  Previous EES, along with other three factors, may increase the chance of excessive epistaxis after EES, while pre-operative corticosteroid therapy may reduce the risk to some extent.
