MRI & Other Questions

MRI (Magnetic Resonance Imaging)

If you are to undergo an MRI (Magnetic Resonance Imaging), remove the sound processor prior to the procedure. The implant and abutment remain in place.

Caution:

• The Baha sound processor is a digital, electrical, medical instrument designed for specific use. As such, due care and attention must be exercised by the user at all times.
• The titanium screw of the Baha is screwed from outside into the bone. Because of this procedure, there is some risk of infection. With proper healing and normal precautions, this is not an issue for the great majority of recipients.
• Daily care is required. This consists of using a very soft toothbrush-like tool (provided in your aftercare kit) to scrub around the post and skin area to keep it clean and not infected. Regular use of an antibiotic ointment assists in minimizing the possibility of infection.
• The sound processor is not waterproof! Never wear it in heavy rain, in the bath or shower!
• Do not expose the sound processor to extreme temperatures. The sound processor is designed to operate within the temperature ranges +5°C (+41°F) to +40°C (+104°F). In particular, battery performance deteriorates in temperatures under +5°C. The processor should not be subject, at any time, to temperatures below -20°C (-4°F) or above +50°C (+122°F).
• This product is not suitable for use in flammable and/or explosive environments.
• Always use the audio adapter when connecting an external audio source to your sound processor.
• Portable and mobile RF (radio frequency) communications equipment can affect the performance of your sound processor.
• The sound processor is suitable for use in electromagnetic environments with mains power of typical commercial or hospital quality, and power frequency magnetic fields of typical commercial or hospital levels. It is intended for use in an electromagnetic environment in which radiated RF (radio frequency) disturbances are controlled.

You should also know:

A sound processor will not restore normal hearing and will not prevent or improve a hearing impairment resulting from organic conditions.

• Infrequent use of a sound processor may not permit a user to attain full benefit from it.
• The use of a sound processor is only part of hearing rehabilitation and may need to be supplemented by auditory training and instructions in lip-reading.
