The MED‑EL Cochlear Implant System is also intended to evoke auditory sensations via
electrical stimulation of the auditory pathways for individuals with single–sided deaf‑
ness, which is defi ned as severe to profound hearing impairment in one ear and normal
hearing or mild to moderate hearing impairment in the other ear.
Indications
• The cochlear implant evokes acoustic perception via electrical stimulation of the
auditory nerve. A functional auditory nerve is thus a prerequisite for successful
cochlear implantation.
• MED‑EL strongly recommends using optimally fi tted hearing aids for a minimum of
three months before deciding that a cochlear implant is the preferential option.
However, if an individual was deafened by an infectious disease, which can lead to
ossifi cation and if there are signs of cochlear ossifi cation there may be no need to
try a hearing aid. In these cases, implantation should not usually be delayed.
• To obtain the optimal benefi t from the implant, the prospective implant users and
their families shall be highly motivated and have realistic expectations about the
expected benefi t of the implant and shall understand the importance of returning
to the implant centre for regular audio processor programming, assessment ses‑
sions and training.
• A preoperative assessment according to the local professional standards must be
conducted.
• Cochlear implants SYNCHRONY 2 Standard are intended to be used in open
cochleae (no obliteration or ossifi cation) for an electrode insertion depth of about
31 mm.
• Cochlear implants SYNCHRONY 2 Medium are intended to be used in open cochleae
(no obliteration or ossifi cation) with mild malformation for an electrode insertion
depth of about 24 mm as per request of the surgeon.
