Abstract
Severe disabling tinnitus (SDT) refers to a symptom severe enough to disrupt affected patients’ routine and keep them from performing their daily activities. SDT of a predominantly central origin has been treated successfully with benzodiazepines and GABAergic drugs. Our aim was to test the control of SDT of predominantly cochlear origin by benzodiazepines and GABAergic drugs. We followed the format of a prospective, randomized, single-blind clinical trial at an academic tertiary-care hospital. We studied 30 patients, all with SDT of clear cochlear origin. We treated 10 patients with placebo (group 1), 10 with benzodiazepine drugs (group 2), and 10 with benzodiazepine and GABAergic drugs (group 3). We recorded a decrease in the annoyance and intensity of SDT as measured by a visual analog scale ranging from 1 (negligible) to 10 (unbearable). We found statistically significant improvement in comparing groups 2 and 3 with group 1 but found no significant difference when groups 2 and 3 were compared. Addition of GABAergic to benzodiazepine drugs does not modify the treatment results in SDT of a predominantly cochlear origin.
