  • Abstract
  • Look Inside

 The bone conduction acuity of 874 cases who had tympanoplasty was reported. The bone conduction acuity decreased postoperatively in about 10% of the subjects with better preoperative bone-conduction threshold and in about 16% of those with less preoperative acuity. This tells us that the operation of the patients with mixed type hearing loss should be carried out with special care. The postoperative loss in the bone conduction acuity was mostly found in those whose tympanums showed severe pathological changes. From the long-term observation it was found that some cases increased, while some decreased, the bone conduction acuity after tympanoplasty.
