title: [Mastoid surgery for secretory otitis media with mixed hearing loss].
abstract: OBJECTIVE
  To analyze the therapeutic effect of mastoid surgery for secretory otitis media with mixed hearing loss.
  
  
  METHODS
  A retrospective analysis was conducted of the data from 26 cases (43 ears) of secretory otitis media with bone conduction hearing loss collected from 2001 to 2008. Thirty-two ears were treated with mastoid surgery and myringotomy with insertion of ventilation tubes. All the patients received medications after the operation.
  
  
  RESULTS
  All the patients showed obvious improvement after mastoid surgery. The average pure tone of air conduction hearing threshold was about 25 dB after the surgery, with the average pure tone of bone conduction hearing threshold of about 15 dB. The patients were followed up for 1-2 years during which no significant change in hearing was recorded, and no middle ear effusion in the tympanic cavity was found after removal of the ventilation tubes.
  
  
  CONCLUSIONS
  Persistent secretory otitis media can be associated with mixed hearing loss, and mastoid surgery can significantly enhance the hearing level to produce positive therapeutic effects.
