- Perioperative and postoperative complications [ Time Frame: 5 years from date of surgery ]We will track any major and minor complications intraoperatively and postoperatively in all study participants.
- Audiologic performance [ Time Frame: 5 years from date of surgery ]We will complete physiological, psychophysical, and speech based tests to determine audiologic performance following ABI surgery.
- ABI electrophysiologic parameters [ Time Frame: 5 years from date of surgery ]We will examine parameters for electrode activation postoperatively in all study participants.
