Fourty-one cases (47 ears) of tympanisclerosis were examined and the features of the disease were discussed on the basis of both the statistical analysis and the operation findings. A tympanosclerosis does not always take place an end-result of well controlled inflammation. It is frequently accompanied by a residual inflammation. According to our experiences with histologic examination of removed tissues, an inflamma tory mucosa around the ossicles may demonstrate a small focus of dense fibrosis. This focus possibly presents to us an initial pattern of onset of tympanosclerosis. Histological examination failed to demonstratean invasive type of tympanosclerosis. So we think the disease involves the mucous membrane alone. Tympanoplasty operation was successful in a case of localized tympanosclerosis, but frequently unsuccessful in an extensive case where a sclerotic tissue involves all the ossicles
