Abstrakt		Objective: Reliable preoperative assessment of the central auditory pathways is advisable in cochlear implant candidates. In order to decide the reliable technique, subjective and objective test techniques are correlated to each other. Patients and Methods: Electroaudiometry (EAM) is a subjective, noninvasive investigation where the stimulating electrode lays in the external ear canal. It was performed in 86 deaf patients. In contrast, to detect the electrically evoked auditory brainstem responses (EABR), myringotomy is necessary and a stimulating electrode has to be inserted close to the round window. EABR is was performed in 52 deaf patients. The Results of both examination techniques were compared by using logistic regression. The data obtained were also compared with the hearing results obtained following cochlear implantation (CI) in 62 patients.Results: Using EAM, the positive respondse was obtained in 154 of the 172 ears (90 %). In EABR, positive responses were obtained in 67 of 104 ears (64%). Among them unilateral cochlear implantation was performed in 62 patients. Logistic regression tests showed a significant correlation between EAM and EABR. The comparison of EAM and EABR prior to CI with the post CI hearing data revealed a strongly significant correlation.Conclusion: Results of EAM and EABR were comparable. Results obtained with EAM or EABR were predictive for successful cochlear implant usage.
