Objective The aim of this article is to research the radical mastoidectomy and primary tympanoplasty to attain radical cure of the mastoid focus as well as rebuilding the sound- conducting structure of the tympanic cavity to improve the audition. Method The autobone and temporal fascia were taken as the transplants after the radical mastoidectomy under microscopy, and then to carry out the operation of Portmann｀ s tempanoplasty of 2nd and 3rd types of 2nd class.Result Non of the cholesteatoma was relapsed after follow- up for 1～ 4 years.The efficiency rate of tympanoplasty is of 89.47% .The average audition increased was 19 dB HL. Conclussion Radical operation for cholesteatoma should be associated with tympanoplasty if having condition. We recommend that the opening tympanoplasty should be used, and use autobone as a artificial auditory ossicles.
