    Abstract:
    OBJECTIVE: To investigate the effect of open method tympanoplasty with mastoid obliteration with homograft tooth and reconstruction of the attic wall. METHOD: Fifty-two cases with cholesteatoma or skeletal ulcer otitis media were performed the open method tympanoplasty with mastoid obliteration with homograft tooth and reconstruction of the attic wall after radical mastoidectomy. RESULT: External auditory canals of 48 patients were normal in appearance. The transplanted membrane in 46 ears was survived. The dry-ears rate was 92.31% and the average time waited till dry-ears was 17.56 +/- 4.16 days. The air-conducting hearing levels of average language frequency have been enhanced over 15 dB HL in 41 ears. An air-bone gap of less than 20 dB HL was achieved in 31 ears. CONCLUSION: The open method tympanoplasty with mastoid obliteration with homograft tooth and reconstruction of the attic wall can recovery the anatomic structure and physiological function of external auditory canal and middle ear better. The long-term effect on improving hearing was significant.
