Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with unilateral, severely invalidating tinnitus that has not responded to conventional treatments.

Probably not a fit

Patients with detectable causes for their tinnitus or those who do not meet the specific audiometric criteria may not benefit from this study.

What this trial studies

This study investigates the use of an auditory brainstem implant (ABI) to treat patients suffering from severely invalidating unilateral tinnitus. The ABI is designed to restore hearing in individuals with dysfunction of the cochlear nerve and has shown a side effect of tinnitus reduction in previous cases. The study aims to evaluate the efficacy and safety of the ABI specifically for tinnitus suppression, as this is the first time it is being used primarily for this purpose. Participants will undergo the implantation procedure and be monitored for outcomes related to their tinnitus symptoms.

Why it matters

Potential benefit: If successful, this approach could provide significant relief for patients suffering from debilitating tinnitus, improving their quality of life.

How similar studies have gone: While the use of ABI for tinnitus is novel, similar approaches with cochlear implants have shown promising results in reducing tinnitus symptoms.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Unilateral tinnitus
* Severely invalidating tinnitus
* Men or women, age \>18yr
* Tinnitus that is present \>1 years and was stable during the last year
* Tinnitus that is nonresponsive to indicated conventional existing treatments (hearing aids and cognitive behavioral therapy (CBT)). If a psychologist has indicated that CBT may ameliorate tinnitus complaints, the patient should have tried CBT for long enough time to reasonably argue that these treatments were not successful. This is the same for hearing aids.
* Ipsilateral ear: pure tone audiometry (PTA) thresholds \>40dB and \<90dB (mean over 1-2-4kHz)
* Functional hearing in the contralateral ear with pure tone audiometry thresholds \<35dB (mean over 1-2-4 kHz) and with a minimum Δ25dB compared to the ipsilateral ear.
* Informed consent after extensive oral and written information about the surgery, complications and the uncertain effect of the ABI on tinnitus

Exclusion Criteria:

* Detectable cause for tinnitus that requires causal therapy (e.g. vestibular schwannoma, glomus tumor, otosclerosis, arteriovenous malformation) as investigated by radiological and otological examination
* Psychiatric pathology and/or an unstable psychological situation as declared by a psychiatrist
* Unrealistic expectations as declared by the investigator and/or psychiatrist
* Life expectancy \<5 years
* History of blood coagulation pathology
* ASA \>II
* Pregnancy
* Anatomic abnormalities that would prevent appropriate placement of the stimulator housing in the bone of the skull
* Anatomical abnormalities or surgical complications that might prevent placement of the Auditory Brainstem Implant Active Electrode Array
* Known intolerance to the materials used in the implant (medical grade silicone, platinum, iridium and parylene C)
