Summary
This is an exploratory pilot open-label study to identify the signal changes on fMRI of
patients with tinnitus and with temporary suppression of the tinnitus with IV lidocaine.
Patients will include those with hearing loss (both unilateral and bilateral) and tinnitus,
subjects with normal hearing and tinnitus, and control subjects with normal hearing and no
tinnitus. Eligible subjects will have functional and subjective data collected at baseline,
receive an IV lidocaine infusion, and have functional and subjective data collected
post-infusion for comparison and identification of involved neural networks.
