title: Electrode and device problems: manifestation and management.
abstract: A total of 119 children were implanted with the Nucleus 22 implant on the Nottingham program by March 1996. Twenty-five (i.e. 21%) of these had an electrophysiologically confirmed fault on at least 1 channel and 6 (i.e. 5%) had experienced total device failure. How these problems were first manifested and what the subsequent effects were on the child and family were determined by means of questionnaires and detailed examination of clinical notes. Our findings indicated that 76% of all internal device faults were initially detected in tuning or electrophysiological measurement. All parents expressed deep anxiety about the threat of device failure; cases of total failure occurring over a long period of time resulted in the greatest distress and effect on the family. Recommendations are made for companies to assist clinics in minimizing such effects.
