Abstrakt:	Objectives: Detection of antichoclear antibodies in patients with sudden deafness (SD) ranges from five to forty one percent depending on authors. We tried to correlate the level of antibodies measured by Western-blot (WB) and hearing loss. Patients and Methods: Forty nine subjects bearing of SD and a positive WB for bovine cochlear antigen. Hearing loss average was measured at the onset and after treatment with deflazacort 1 mg/kg per day by means of audiometry, and antibody titles were quantified in the diluted sera. Results: Initial loss was 49.4+/-20.6%, and after corticotherapy it was 15.9+/-18.0%. There was no statistically significative correlation titles-hearing loss (y=0.1122x+30.613; R2=0.7552) nor titles-recovery (y=-0.0818x+8.,65; R2=0.3229). Conclusions: Although predictive capability for treatment response is accepted for WB, quantifying of the antibody titles in patients with SD does not allow to make a prognosis about the average hearing recovery.
