摘要
The noise levels in the cochlea when a drill is used in the mastoid process were calculated from vibration measurements on intact skulls of human cadavers and temporal bones. In ear surgery, the ipsilateral cochlea is apparently exposed to noise levels of about 100 dB and the contralateral cochlea to levels 5-10 dB lower every time the drill is used. This noise trauma may account for some of the high-tone sensorineural hearing losses after tympanoplasty.
