Bone Conduction Hearing Devices

Passive devices

A passive implant means that no working parts are contained in the implant. The working part, the vibrating transducer, is encased together with the sound processor in one unit which is worn externally on the head behind the ear. The surgical part is most often a titanium abutment, which protrudes through the skin, or occasionally a magnet, which is placed under the skin.

The abutment is inserted surgically through the skin and a few millimetres into the bone.

At Bradford Royal Infirmary the passive implantable devices we provide are:

Cochlear™ Baha® System

The Cochlear™ Baha® System consists of three different devices:

  • Cochlear™ Baha® 5 Sound Processor – this is the smallest device suitable for a mild hearing loss
  • Cochlear™ Baha® 5 Power Sound Processor – suitable for a moderate hearing loss
  • Cochlear™ Baha® 5 SuperPower Sound Processor – suitable for a moderate-severe hearing loss

The Baha® 5 range can be worn on an abutment, on a magnet, or on a temporary wear option including a Cochlear™ Baha® SoundArc™, headband, and softband. Each device is available in a range of colours to suit different hair types.

When clipped on to the abutment, the processor sits just behind the ear. This is the smallest of the range, the Baha® 5.

Surgery for abutments (Baha® connect) or magnets (Baha® attract) is available from the age of 5 years old.

Anyone from infants to adults can be fitted with a softband.

A soundarc® and headband are made of harder material, so are often not as comfortable to wear for very young children.

OTICON MEDICAL PONTO

For a mild hearing loss, we can fit the Ponto 4.

For a moderate hearing loss, we fit the Ponto 3 SuperPower, which is also available in a range of colours as above, and is larger than the Ponto 4. This is the reverse view of a Ponto 3 SuperPower in black. The grey disc clips onto the patient’s abutment (Image courtesy of Oticon Medical).

An Oticon Ponto device can be worn on an abutment. Surgery for an abutment is possible for patients aged 5 years and older.

They can also be worn on a non-permanent fitting, using either a softband or a headband. A softband can be worn from infancy, a headband is usually only used for older children and adults.

MED-EL ADHEAR

The Adhear from Med-El is worn on an adhesive patch. The patch is designed to be worn on the skin behind the ear, and to stay in place for up to 5 days. It is suitable to be worn whilst showering and bathing – without the BCHD attached!

This is only suitable for patients with a mild hearing loss, or for single-sided deafness.
