Tinnitus is the perception of sound in the absence of an external sound. Prevalence in the general population is 10 to 15%, with tinnitus severely impacting quality of life in 1-2 percent of the population. Tinnitus therapy is based on counselling, cognitive and behavioural therapies in combination with sound therapies which mostly rely on masking.
For cochlear implant candidates, the ability to use hearing aids and maskers is limited by the degree of their hearing loss. Reports of tinnitus prevalence in this group range from 67 to 100% with a mean of 80%.
In cochlear implant (CI) recipients, tinnitus suppression primarily occurs during active use of the cochlear implant system. In some CI recipients residual inhibition of tinnitus occurs when the implant is switched off. While the benefits of CI implantation on tinnitus are well documented, there is a group of recipients where tinnitus remains a concern in the implanted ear post-operatively.
The primary aim of this study is to investigate the benefits of incorporating a tinnitus masking feature into the CI sound processor that optimises tinnitus suppression with minimal annoyance to the user. Furthermore a questionnaire will be employed to capture the prevalence, degree and nature of tinnitus in recipients.

Neural Substrates of Tinnitus in an Auditory Brainstem Implant Patient: A Preliminary Molecular Imaging Study Using H2 15 O-PET Including a 5-year Follow-up of Auditory Performance and Tinnitus Perception.
It was previously demonstrated that tinnitus due to profound unilateral hearing loss can be treated by the use of electrical stimulation via a cochlear implant (CI) with long-lasting positive effects....
Complete alleviation of tinnitus perception is rarely achieved by current therapeutic interventions. However, adequate therapy may induce a small or large decrement of the tinnitus. The assessment of ...
A nonspecific symptom of hearing disorder characterized by the sensation of buzzing, ringing, clicking, pulsations, and other noises in the ear. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; and other conditions.
Pathological processes of the VESTIBULOCOCHLEAR NERVE, including the branches of COCHLEAR NERVE and VESTIBULAR NERVE. Common examples are VESTIBULAR NEURITIS, cochlear neuritis, and ACOUSTIC NEUROMA. Clinical signs are varying degree of HEARING LOSS; VERTIGO; and TINNITUS.
Idiopathic inflammation of the VESTIBULAR NERVE, characterized clinically by the acute or subacute onset of VERTIGO; NAUSEA; and imbalance. The COCHLEAR NERVE is typically spared and HEARING LOSS and TINNITUS do not usually occur. Symptoms usually resolve over a period of days to weeks. (Adams et al., Principles of Neurology, 6th ed, p304)
The cochlear part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The cochlear nerve fibers originate from neurons of the SPIRAL GANGLION and project peripherally to cochlear hair cells and centrally to the cochlear nuclei (COCHLEAR NUCLEUS) of the BRAIN STEM. They mediate the sense of hearing.
An accumulation of ENDOLYMPH in the inner ear (LABYRINTH) leading to buildup of pressure and distortion of intralabyrinthine structures, such as COCHLEA and SEMICIRCULAR CANALS. It is characterized by SENSORINEURAL HEARING LOSS; TINNITUS; and sometimes VERTIGO.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
