2 Sound Processor Clinician's Quick Guide
®
Intended use
The Cochlear Osia System uses bone conduction to transmit sounds
to the cochlea (inner ear) with the purpose of enhancing hearing.
Indications
• The Cochlear Osia System is indicated for patients with conductive,
mixed hearing loss and single-sided sensorineural deafness (SSD).
• Patients should have sufficient bone quality and quantity to
support successful implant placement.
• The Osia System is indicated for patients with up to 55 dB SNHL.
Wear the sound processor
To achieve the optimal hearing outcome, it is important that you
show recipients how to correctly place the Cochlear
Processor on their implant.
To reduce the risk of losing the sound processor, you can use the
Safety Line or Cochlear Headband. See the Osia 2 Sound Processor
User Manual for details.
CAUTION: It is important to position the sound processor
correctly to get the best performance.
Selecting magnet strength
Selecting the magnet strength is key to effective retention of the
sound processor. If a magnet is too weak, the processor may fall off
the head. If it is too strong, the recipient can experience discomfort
or skin irritation. Magnet strength ranges from 1 (weakest) to
4 (strongest).
Magnet selection can be affected by several factors:
• skin flap thickness
• use of a Cochlear SoftWear
Pad
™
(for recipient comfort)
• use of retention aids (e.g. Cochlear Headband, Safety Line)
• thickness of the recipient's hair
Inserting and removing a magnet
•
To insert a magnet
Use the magnet tool to pick up the magnet. To couple it correctly make
1
sure that the gripping edges in the tool are aligned with the notches in the
•
magnet.
Insert the magnet into the sound processor and turn clockwise to lock in
2
to place.
NOTE: Using the tool will ensure that the magnet is inserted with
the correct magnetic pole orientation.

Clinical benefit
Most recipients of a bone conduction hearing solution will experience
improved hearing performance and quality of life compared to
unaided listening.
Serious incidents
Serious incidents are rare, any serious incident in relation to your
device should be reported to your Cochlear representative and to the
medical device authority in your country, if available.
