You may be eligible if
18 years or older, at time of consent.
Postlinguistic moderately severe to profound sensorineural hearing loss, defined by a four frequency (500, 1000, 2000, 4000 Hz) pure-tone average unaided threshold (PTA4) ≥ 60 decibels hearing level (dB HL), in the ear to be implanted (For this study, moderately severe is defined by a four-frequency, pure-tone average threshold (PTA4) over the range 500 through 4000 Hz of more than 55 dB HL through 70 dB HL, inclusive. Profound is defined by a PTA4 of more than 90 dB HL).
Pure-tone average unaided threshold (500 through 4000 Hz) ≥ 30 dB HL, in the contralateral ear.
Preoperative aided word score ≤ 40% correct in the ear to be implanted.
Evidence of pneumococcal vaccination (e.g., Pneumovax) according to local guidelines.
Candidate is proficient in the language used to assess speech perception performance.
Willing and able to provide written informed consent.
You may not be if
Intra-axial (within the brain) lesions or deafness due to lesions of the acoustic nerve affecting the ear to be implanted.
Middle ear infection (including acute otitis media, chronic otitis media, suppurative otitis media, or serous drainage) in the ear to be implanted either at the time of surgery or within 3 months prior to enrolment.
Active autoimmune disease or active immunosuppressive therapy.
Presence of a tympanic membrane perforation or a history of otologic surgery within 3 months prior to enrolment, in the ear to be implanted.
Previously reported diagnosis of auditory neuropathy, in the ear to be implanted.
Previously reported diagnosis, in the ear to be implanted, of Large Vestibular Aqueduct Syndrome (LVAS), Meniere's disease, or cochlear hydrops.
Ossification, otosclerosis, malformation or any other cochlear anomaly, such as common cavity, that might prevent complete insertion of the electrode array, in the ear to be implanted.

Previously reported diagnosis of bacterial meningitis.
Known allergic reaction or contraindication to dexamethasone or corticosteroids.
Severe, or poorer, bilateral sensorineural hearing loss prior to 5 years of age, as reported by the subject. (For this study, severe is defined by a PTA4 of more than 70 dB HL through 90 dB HL, inclusive).
Severe, or poorer, sensorineural hearing loss for more than 20 years, as reported by the subject, in the ear to be implanted.
Prior cochlear implantation in either ear.
Medical plan for cochlear implantation during the clinical investigation, contralateral to the ear to be implanted.
Medical or psychological conditions that contraindicate general anaesthesia, surgery, or participation in the clinical investigation as determined by the Investigator.
Unrealistic expectations on the part of the subject regarding the possible benefits, risks, and limitations inherent to the surgical procedure(s) and prosthetic devices, as determined by the Investigator.
Women who are pregnant.
Additional disabilities that may affect the subject's participation or safety during the clinical investigation.
