About this trial

The purpose of the study is to evaluate the long-term safety and effectiveness of cochlear implantation of the approved population in adults and children with single-sided deafness and asymmetric hearing loss.

Eligibility criteria

Qualifiers

Five years of age or older at the time of implantation

Unilateral profound hearing loss, as defined by a pure-tone average (500, 1000, 2000, and 4000 Hz) of 90 dB or greater in the ear to be implanted

Sensorineural hearing loss in the ear to be implanted, as defined by an air-bone gap less than or equal to 10 dB at two or more frequencies out of 500, 1000, 2000, and 4000 Hz and a diagnosed pathology of the outer or middle ear

Normal hearing or mild to moderate hearing loss in the non-implanted ear, as defined by a pure-tone average (500, 1000, 2000, and 4000 Hz) of 55 dB or less

Disqualifiers

Duration of profound hearing loss of 10 years or more

Absence of cochlear development or non-functionality of cochlear nerve

Other retrocochlear hearing loss

Evidence of severe cochlear malformation (i.e., common cavity or ossification)
