title: [Effect of multi-technique of intact canal and scute rebuilding in treatment of middle ear cholesteatoma].
abstract: OBJECTIVE
  To assess the results of multi-technique with intact canal and scute rebuild operation for middle ear cholesteatoma.
  
  
  METHODS
  Analysis of 113 cases (males 60, females 53, with mean 42.7 years old), of which with double ears of 11 cases, and totally 124 ears (11 ears for one review, an ear for third time review, and totally 137 operations) was retrospectively performed. Ten cases less than 19 years old were operated from September 2001 to January 2006 for middle ear cholesteatoma as well as ossiculoplasty with intact canal and scute rebuild etc multi-technique. All cases were followed up for a mean (36.58 +/- 20.47) months.
  
  
  RESULTS
  There were 118 ears (95.2%) without cholesteatoma recurrence. Six ears were found cholesteatoma recurrence. Other 6 post-operation ears with drum re-perforation and hearing drop were re-operated. The pre-operation air-bone gap (ABG, average of 0.5, 1, 2 kHz) of 124 ears, with in initial 112 ears, was (33. 61 +/- 12.35) dB, while that of post-operation ABG was (13.58 +/- 9. 27) dB, by partnership t test, t = 18.35, P < 0.01. The pre-operation ABG in reviewed 12 ears at the first pre-operation was (38.83 +/- 12.43) dB, but post-operation ABG (10.38 +/- 8.99) dB, by partnership t test, t = 5.38, P = 0.00022. The ABG closure to within 20 dB was tested in 100 ears while ABG over 20 dB but air conduct (AC) in 40 dB was in 6 ears, and then as succeed was in 106 ears (85.5%). ABG closure within 10 dB was in 50 ears and though ABG over 10 dB but ABG reduced over 30 dB was in 9 ears (59/124, 47.6%) as which as best result. Bone conduct (BC) threshold was tested of 21 ears (16.93%) with raise 1-9 dB, of 42 ears (33.9%) with no change and of 61 ears (49.2%) with descend 1-28 dB. Of 10 cases less than 19 years old post-operation ABG was (8.80 +/- 5.27) dB, which indicated that all cases was as succeed.
  
  
  CONCLUSIONS
  Using intact canal and scute rebuild etc multi-technique a normal canal, hearing improvement and very low recurrent could be gained for middle ear cholesteatoma, especially in juvenile and children. The multi-technique should be almost no damage for hearing bone conduct.
