title: [Application of floating tube in dilation of eustachian tube under nasal endoscopy to treat post-irradiation secretory otitis media].
abstract: OBJECTIVE
  To analyse the function of eustachian tube in post-irradiation secretory otitis media and investigate the curative effect of dilating eustachian tube with Swan-Gans thermodilution catheter for treating post-irradiation secretory otitis media in NPC patients.
  
  
  METHODS
  Twenty-one (37 ears) post-irradiation secretory otitis media patients with NPC were selected in this study, by using eustachian tube function synthetic inspection facility (JK-04A model), the eustachian tube function was examined, and the obstructive eustachian tube was dilated with Swan-Gans thermodilution catheter under nasal endoscopy.
  
  
  RESULTS
  The eustachian tube function in 37 ears with post-irradiation secretory otitis media reveals normal, obstructive, insufficiency and opening model was 2, 21, 8, and 6 respectively. The total curative effect of dilating eustachian tube with Swan-Gans thermodilution catheter to treat post-irradiation secretory otitis was 43.2% (16/37).
  
  
  CONCLUSIONS
  The eustachian tube function in post-irradiation secretory otitis media mainly reveals obstructive disturbance. The application of Swan-Gans thermodilution catheter in dilation of obstructive eustachian tube under nasal endoscopy will increase the curability of post-irradiation secretory otitis media.
