Warnings
Medical Treatments Generating Induced
Currents
Some medical treatments generate induced currents that
may cause tissue damage or permanent damage to the
cochlear implant. Warnings for specific treatments are
given below.
· Electrosurgery: Electrosurgical instruments are capable
of inducing radio frequency currents that could flow
through the electrode array.
Monopolar electrosurgical
instruments must not be used on the head or neck of a
cochlear implant patient as induced currents could cause
damage to cochlear tissues or permanent damage to the
implant.
Bipolar electrosurgical instruments may be
used on the head and neck of patients, however, the
cautery electrodes must not contact the implant and
should be kept more than 1 cm (~ ½ in.) from the
extracochlear electrodes.
