[Reconstruction acusticus back wall and tympanoplasty with homograft costal cartilage]
Objective:
To eliminate the back wall defect of external canal and opened mastoid cavity which was remained from radical mastoidectomy.
Method:
We performed the operation on 17 cases after radical mastoidectomy by using reconstruction of the canal wall and fill-in opened mastoid cavity and ossicular replacement prostheses made of homograft costal cartilage. The tympanoplasty had been made operated for all patients, 8 ears were PORP, the others were TORP.
Result:
All cases were followed-up for 6 months-2 years. The external canal of all patients are normal in appearance. The total effective rate of gain (> 15 dB) was 14 ears (82.4%). Only one patient whose tympanic membrane was perforated postoperation 3 months.
Conclusion:
Reconstruction of acusticus back wall and hearing after radical mastoidectomy with homograft costal cartilage is effective to prevent mastoid cavity infection and improve hearing.
