2. In addition to meeting current cochlear implant indications, subjects must also
possess preoperative unaided hearing thresholds between 40 to 65 dB HL at 250 & 500Hz
in the ear to be implanted.

3. Fluent speaker in the local language used to assess clinical performance

4. Eighteen years of age or older at the time of implantation with no upper age limit
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Evidence of hearing loss prior to 5 years of age.

2. Sensorineural severe-to-profound hearing loss greater than 20 years at 2 kHz and
above.

3. Simultaneous bilateral cochlear implantation or prior cochlear implantation in the ear
to be implanted.

4. Additional disabilities that may affect the subject's participation or safety during
the clinical investigation.

5. Medical or psychological conditions that contraindicate undergoing general anaesthesia
or surgery.

6. Ossification, malformation or any other cochlear anomaly, such as common cavity, that
might prevent complete insertion of the electrode array, as confirmed by medical
examination.

7. Hearing impairment due to lesion or neuropathy of the acoustic nerve, VIII nerve or
central auditory pathway.

8. Active middle-ear infection,

9. Tympanic membrane perforation

10. Unrealistic expectations on the part of the subject, regarding the possible benefits,
risks, and limitations that are inherent to the surgical procedure(s) and prosthetic
devices

11. Unwillingness or inability of the candidate to comply with all investigational
requirements.

12. Patients with existing CSF shunts or drains, existing perilymph fistula, skull
fracture or CSF leak.

13. Patients with recurrent episodes of bacterial meningitis.

Summary
Brief summary
The purpose of the feasibility study is to examine audiological outcomes (audiometry and
speech perception) and safety (adverse events and adverse device effects) with the Nucleus
CI532 cochlear implant in group of adult subjects (n=12) who meet current criteria for
cochlear implantation.
