1. A method, comprising:
forming at least a portion of a hole in an apical region of an inner ear of a recipient;
positioning at least one electrode of a first electrode assembly at the at least the portion of the hole in the apical region of the inner ear of the recipient;
performing one or more electrical measurements via electrodes of a second electrode assembly implanted in, or in proximity to, the inner ear; and
analyzing data obtained as a result of the one or more electrical measurements performed via the electrodes of the second electrode assembly to determine whether the at least one electrode of the first electrode assembly has a low-impedance path to a perilymphatic fluid space of the inner ear.
