title: [Intact canal wall mastoidectomy and tympanoplasty in treating patients with cholesteatoma of the middle ear and mastoid].
abstract: OBJECTIVE
  To evaluate the value of intact canal wall mastoidectomy and tympanoplasty in treating patients with cholesteatoma of the middle ear and mastoid.
  
  
  METHODS
  Fifty-seven patients underwent intact canal wall mastoidectomy and tympanoplasty.
  
  
  RESULTS
  In all cases who had been followed up for 1-8 years, 5 ears were infected, 2 patients needed second operation, and 3 ears suffered from cholesteatoma recurrence. Tympanic membrane of 29 ears kept integrity although with pocket retraction to some extent. Extrusion of the prosthesis occurred in 2 cases. The postoperative audiometric measurement (the average hearing threshold at 0.5, 1.0, 2.0 kHz HL) was improved by more than 10 dB HL in 39 ears (72.2%), the mean air bone gap (ABG) of 29 ears was reduced to less than 20 dB HL.
  
  
  CONCLUSIONS
  Intact canal wall technique could remain anatomical structure and improve hearing effectually in treating the patients with cholesteatoma in the middle ear and mastoid.
