Summary:To estimate binaural asymmetric sensorineural hearing loss in own material of patients treated in Dept. of Phoniatrics and Audiology. The retrospective analysis was performed on the group of 1816 patients hospitalized in 2008 due to hearing disorders. Asymmetry of hearing loss was classified on Margolis and Saly criteria in PTA, and in ABR results in children. Binaural asymmetric sensorineural hearing loss was found in 70 patients (3.9%). In a group of 46 differences of inter-aural threshold level in PTA were estimated on 21 to 30 dB. After audiological examination 14% of this patients were qualified for MRI investigation, in 2 (3%) of them acoustic neurinoma was found. The hearing aids fitting were performed in 44% of a group of 70 patients.
