Who is a suitable candidate for a Baha

The usual candidates for a BAHA system are those people who for a variety of reasons cannot wear standard 'in the ear' air conduction hearing aids or who would benefit most from amplification by bone conduction.

  • Some people have allergies to earmolds or cannot have molds in their ears due to irritation or infection which can become chronic.
  • People who have malformed or absent outer ear and ear canals as is common in medical conditions such as Treacher Collins syndrome or Microtia.
  • People who have single sided deafness due to surgery, head trauma or disease. For example people who have Meniere’s Disease or an acoustic neuroma.
  • In Canada, stage one surgery for BAHA has been implanted into children as young as 13 months at the Hospital for Sick Children in Toronto. Stage two surgery has been done as early as 22 months.
  • For infants, an interim measure young infants can be provided with a BAHA softband allowing them to use a BAHA. This is a tight headband which the infant wears to hold a BAHA against the skull.
