In a retrospective study 103 patients with acute acoustic trauma (AAT) were investigated. The control group (53 patients) was treated with Dextran 40 (10% solution), neurotrop vitamins and Betahistin. Bencyclan was administered additionally in the test group (50 patients). Statistical analysis of the audiometric data showed the following results: 1. Mean hearing levels of the test group showed better improvement of threshold shifts, if the therapy started within 2 days or after more than 10 days after the AAT. 2. Regression-and correlation coefficients, however, in a regression analysis of absolute hearing gains and hearing losses before therapy, did not indicate a substantial effect of Bencyclan. 3. Neither did statistical tests with relative hearing gains show any significant differences between test-and control groups. Consequently Bencyclan is not likely to have a positive effect in AAT, if it is administered in the above mentioned way. |
