Abstract: OBJECTIVE To investigate and evaluate the effects of intact-bridge tympanoplasty using auricular cartilage in treating chronic otitis media. METHODS A retrospective review of 86 cases undergoing an intact-bridge tympanomastoidectomywas performed from July,2013 to May,2016.The auricular cartilage was placed on the attic and tympanic antrum entrance to reconstruct the attic. RESULTS The outcome of dry ear and well-epithelialized mastoid cavities was achieved after 4-6 weeks. After 6-month follow-up no recurrence occurred. The pure-tone average threshold improved by (25.4±6.3) dB HL after operation,and the mean air bone gap was elevated. CONCLUSION On the basis of combination of closed and open techniques,the IBM technique is a optimal cure strategy for chronic otitis media,which can not only remove the pathological changes thoroughly to prevent disease recurrence but also maximally improve the hearing of the diseased ear.The closure of attic with auricular cartilage can ensure the space of the ossicular chain.
