Middle-Ear Implant With MET V Transducer (Aka MET V System)

Inclusion Criteria

• •Adult men or women, 18 years of age or older
• •Moderate to severe mixed hearing loss, as a result of a combination of sensorineural hearing loss and chronic ear disease, prior failed tympanoplasties, severe otosclerosis, radical mastoidectomy, or congenital abnormality as evidenced by the following in the ear to be implanted:
• •* Bone conduction thresholds are measurable at 0.5,1,2,3 and 4 kHz
• •* Bone conduction thresholds are 20 dB or poorer at greater than 2 kHz
• •* Air conduction thresholds are 35 dB or poorer at 0.5,1,2,3 and 4 kHz
• •Air-bone gap in ear to be implanted is greater than 15 dB at three or more frequencies from 0.5 - 4 kHz
• •Word recognition appropriate for sensorineural component of loss
• •Non-fluctuating and stable hearing status
• •a. as defined as by no significant change or progression in the bone conduction thresholds \>15dB at two consecutive octaves for at least 12 months.
• •English Speaking (fluent)
• •Realistic expectations for the device
• •Willingness to sign the informed consent and participate in the study
