title: [Clinical therapeutic effects of staging tympanoplasty].
abstract: OBJECTIVE
  To explore the clinic characteristic and curative effect of staging tympanoplasty for chronic suppurative otitis media and cholesteatoma otitis media.
  
  
  METHODS
  Curative effects of 132 patients cured by staging tympanoplasty and 325 patients cured by no staging tympanoplasty were retrospectively analyzed. Curative effects include ABG value (the reduced value of air-bone conduct gaps after operation), recrudescence of cholesteatoma, tympanic membrane reperforation and wet ear after operation.
  
  
  RESULTS
  In staging tympanoplasty group, ABG is 28.4 dB, rate of tympanic membrane reperforation is 1.5%, recrudescence of cholesteatoma is 0% and rate of wet ear after operation is 0%. In no staging tympanoplasty group, ABG is 21.3 dB, rate of tympanic membrane reperforation is 2.2%, recrudescence of cholesteatoma is 4.0% and rate of wet ear after operation is 1.2%.
  
  
  CONCLUSIONS
  The ABG, the rate of recrudescence of cholesteatoma in staging tympanoplasty group is much better than that in no staging tympanoplasty group. Tympanic membrane reperforation and wet ear after operation rate have no significant difference in statistic between two groups. We can conclude that staging operations will maintain and improve hearing level more effectively compare to no staging operation.
