Abstract :

Tinnitus is often accompanied by hearing impairment, although in some cases normal hearing (<25 dB), may mislead the presence ofcochlear or retrocochlear dysfunction. Therefore, further evaluation using OAE and BERA are needed. The purpose of this study isto analyze the relation between cochlea and retrocochlear with normal-hearing tinnitus. A cross-sectional study on 14 normalhearingtinnitus subjects was conducted in out patient otolaryngology Dr.Soetomo Hospital Surabaya with a control group of 11normal-hearing subjects without tinnitus. Statistic analysis were used including Fischer exact test, Mann-Whitney, independent t test,McNemar test and association test Kappa and Likelihood Ratio. From the study, TEOAE there was no significant difference inTEOAE results between study group and control group (p=0.230). DPOAE there was a significant difference in DPOAE resultsbetween study group and control group (p=0.046). In DPOAE evaluation using frequency of 1 KHz, p = 0,003, at 4 kHz the p =0,020, at 6 kHz the p = 0,008 this shows significant difference at frequency of 1, 4 and 6 kHz (p<0,05). Study of BERA thereforethere was no significant difference in BERA (p=0.008). Therefore, the result of BERA between the two groups only latency wave Iwere significantly different (p=0.044). Statistically, none of TEOAE, DPOAE and BERA fulfilled coherency.(FMI 2013;49:272-276)
