The relation of preoperative OAE test and final OAE was tested and it was significant (p<0.005). In male patients, hearing loss in on-pump operation was 18/6% (p=0.002) and in females in on-pump operation was 7/4% and in off-pump operation was 18.2 %( p=0.1). Hearing loss occurred in 4/2% in 1500, 2000 HZ; 12/5% in 2500, 3000 HZ and 83/3% in 3500, 4000 HZ.
