Abstract:

Objective    To  investigate the methodology and efficacy of  endoscopic  eustachian  tube  dilated  catheter  for  chronic  secretory  otitis  media.  Methods    13  patients  with  chronic  secretory  otitis  media  were  performed eustachian  tube  dilated  catheter   placement to  the  isthmus  by   endoscopy.  The dilated catheter  had been prelumed and dilted for two  minutes.  After the  auripuncture，the tympanic was washed  by  hexadecadrol.  Then the tympanic wound has deen embrocated  with  mitomycin  C  spongio-golatine  for  five  minutes.   Results    All patients were successfully operated and  were followed up  for 4 to 5  months.  The fullness disappeared in 11 cases and types “A” tympanograms were found in all the ears. The pure-tone average of hearing thresholds were significantly improved with an average elevation of 10 to 20 dB. No  complications, such  as  middle  ear  infection, bleeding, tympanosclerosis or  tympanic  effusion  were  found  by  endoscopy.  Stuffied  turgidity  and  mild hearing disorder  occurred  in  2  cases  of  anaphylactic  rhinitis while no sever tympanic effusion.  Conclusion    The treatment of endoscopic  eustachian  tube  dilated catheter for  chronic  secretory  otitis  media is safe and easy for operation, in addition, it results in good effect and less injury.
