| Abstract: | 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. |
