Abstract: To summarize the experience of treatment for tympanosclerosis. Methods: The clinical data of 25 cases of tympanosclerosis undergoing tympanoplasty from November 2001 to February 2005 were retrospectively analyzed. Tympanoplasty of grade Ⅰwas performed on all patients. In the operation, temporal fascia was used to repair the drum and self cortex of mastoid bone or artificial porcelain auditory ossicles were used to reconstruct the ossicular chain. Results: The lesion intruded into drum, promontory of tympanum, incudomalleus, stapes and its surroundings, and no cholesteatoma accompanied by. After operation, the hearing upregulated by 15?dB(96%) in 24 patients and vertigo was found in 4. Conclusions: To clear a sclerotic region around the stapes and to reconstruct ossicular chain and tympanic membrane are the key points of success. The response is closely related with the sclerotic region around the ossicular chain.
