Warning
Electrosurgery
Electrosurgical instruments can induce
radio frequency currents that could flow
through the electrode.
Monopolar electrosurgical instruments
must not be used on the head or neck of an
implant patient as induced currents could
cause damage to cochlear/neural tissues or
permanent damage to the implant.
When using bipolar electrosurgical
instruments on the head and neck of a
patient, the cautery electrodes must not
contact the implant and should be kept
more than 1 cm (½ in.) from the electrodes.
Ionising radiation
therapy
Do not use ionising radiation therapy
directly over the implant. It may cause
damage to the implant.
Neurostimulation
Do not use neurostimulation directly over
the implant. High currents induced into the
electrode lead can cause tissue damage to
the cochlea/brainstem or permanent
damage to the implant
Therapeutic
ultrasound
Do not use therapeutic levels of ultrasound
energy directly over the implant. It may
inadvertently concentrate the ultrasound
field and cause tissue damage or damage to
the implant.
