中耳整形再手術例

抄録

In one of 16 cases of plastic operation of the middle ear performed in the authors' clinic, no increase of hearing was seen. By a reoperation, the authors saw fairly good increase of hearing. As the authors did not use the binocular magnifying glass with light in the first operation, they could not find the granulation surrounding the stapes and that the leg of the stapes was broken. In the reoperation the authors took off the granulation sufHciently and saw fairly good result.
