Evaluation of Deep Brain Stimulation (DBS) of the Right Operculum 3 (OP3) in Permanent Non-pulsatile Disabling Tinnitus (TINNOP3-DBS)

This study is testing whether a brain implant (deep brain stimulation device) can reduce severe, constant ringing in the ears (tinnitus) that has not responded to other treatments. The device sends small electrical signals to a specific part of the brain to interrupt the tinnitus signal. **You may be eligible if...** - You are between 18 and 75 years old - You have constant, non-pulsing tinnitus in one or both ears - Your tinnitus is rated 7 or higher on a pain/severity scale of 10 - Your tinnitus severely affects your quality of life (THI score above 76) - Your tinnitus has not improved with other treatments - You have social health insurance coverage **You may NOT be eligible if...** - You have balance or vestibular disorders - You have epilepsy or a brain tumor - You cannot safely undergo surgery or anesthesia - You take blood thinners that cannot be safely stopped around the time of surgery - You are pregnant or breastfeeding - You have progressive dementia or a serious psychiatric illness - You have a contraindication to MRI scans Talk to your doctor to see if this trial is right for you.
