Study Summary
Tinnitus is the perception of sound when no external noise is present. The Center for Disease Control (CDC) estimates over 50 million - nearly 15% of the general public -experience some form of tinnitus. Roughly 20 million people struggle with burdensome chronic tinnitus, with 2 million experiencing extreme and debilitating symptoms. The 2014 Clinical Practice Guideline on tinnitus from the American Academy of Otolaryngology - Head and Neck Surgery summarized the existing state of tinnitus management by stating "A cure for primary tinnitus does not yet exist, and despite claims to the contrary, no method has been proven to provide long-term suppression of tinnitus." The purpose of this study is to look at the safety and efficacy of cochlear promontory stimulation in the short term relief of tinnitus. The secondary goal of the study is to determine the optimum region(s) of the cochlear promontory in planning for an implantable electrical device for long term tinnitus suppression.
Primary Outcome
The Tinnitus Handicap Inventory (THI) has 25 questions with possible answers of Yes (4 points), Sometimes (2 points), and No (0 points). Scores categories are (1-16: Slight or no handicap - Grade 1), (18-36: Mild handicap - Grade 2), (38-56: Moderate handicap - Grade 3), (58-76: Severe handicap - Grade 4), (78-100: Catastrophic handicap - Grade 5). Total score ranges from 0 to 100 with higher scores indicating a worse outcome.
