Eligibility Criteria
Inclusion Criteria
- •18 years of age or older
- •Definite Postlingual onset of severe\-to\-profound hearing loss as documented by completing main stream primary education
- •Preferably, aided mono\- or bisyllabic word score of \>\= 15 % at 65 dB SPL in quiet in the ear to be implanted
- •Local language proficiency
- •Bilateral, sensorineural hearing loss of a mild to moderate degree in the low frequencies and a severe or a greater degree of hearing loss in the mid\-to\-high frequencies, defined as pure\-tone thresholds (PT):
- •\- PT \<\= 60 dB HL at 250, 500, and 750 Hz BUT at one of these 3
- •frequencies a value \<\= 70 dB is acceptable
- •\- PT \>\= 70 dB HL at 2000, 4000, and 8000 Hz
- •Contralateral ear PTA ± 30 dB HL at 250, 500, 750 and 1000 Hz as compared to the ear to be implanted
Exclusion Criteria
- •Previous inner or major middle ear surgery or active middle ear pathology.
- •Cochlear malformation or obstruction as confirmed by pre OP MRI (an MRI is required to exclude obstruction when history indicates a higher risk for obstructions)
- •Presence of additional disabilities that would prevent or interfere with participation in the required study procedures
- •Medical or psychological conditions that contraindicate surgery or impact the ability to manage an implanted device or the study\-related procedures
- •Evidence of central auditory lesion or compromised auditory nerve
- •Concurrent participation in other study
