The aim of this study is to compare hearing threshold shift of ASSR and hearing threshold shift by audiometry in order to prove efficiency of intraoperative measurement of hearing by ASSR
Efficacy
Comparison thresholds shift of ASSR during operation and hearing threshold shift by audiometer before and after operation.

Not applicable |
Not applicable |
Male and Female
1. Patients whose pure tone audiometey are available
before operation.
2. Patients who undergo operations with possibility of hearing improvement such as tympanplasty, stapes surgery and myringoplasty.
3. Patients (or their guardians if they are not adults) who agree to join this study by consent form.
1. Inappropriate patients judged by operators ex. patients whose hearing may not improve.
2. Patients who undergo operation by local anesthesia.
