WARNINGS
CONDITION 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 ionizing 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.
