Efficacy of a Tinnitus Implant for People With Severe Tinnitus Without Damaging the Acoustic Hearing. (EESPIT)
Extracochlear Electrical Stimulation in Patients With Intractable Tinnitus - a Feasibility Study
This is a prospective, intervention-based, non-randomized, pre-post, single-site feasibility study that will involve data collection from individuals with intractable tinnitus.
The study comprises a screening under local anesthesia and a surgery to implant the medical device.
The screening will allow for accurate selection of patients.
For patients not fulfilling the criteria for chronic extracochlear stimulation, the study will stop there.
Patients eligible for chronic stimulation will undergo a second surgery under general anaesthesia involving the implantation of a cochlear implant with an electrode placed outside the cochlea in the vicinity of the round window.
Each surgical procedure will be followed by a series of medical check-ups.
Following implantation, the safety and efficiency of extracochlear chronic stimulation will be evaluated as well as the tinnitus suppression and speech perception.

Hearing loss
大体时间：12months postoperatively
|
The primary objective of this clinical feasibility study is to evaluate safety, and usability of the cochlear implant system when implanted extracochlear, near the round window.
This includes no major deterioration of hearing thresholds.
Hearing thresholds will be measured by pure tone audiometry.

Tinnitus suppression
大体时间：6 months and 12 months
|
Demonstrate the efficiency of extracochlear electrical stimulation for tinnitus suppression after 6 and 12 months after chronic extracochlear electrical stimulation.The change in self-reported tinnitus severity after 12 months of chronic extracochlear electrical stimulation evaluated with the VAS-scores for tinnitus intensity and annoyance, and the TQ and TFI questionnaires.
