FDA's MAUDE database holds 3,452 reports that name the brand "HiRes 90K" (cochlear implant), received between October 2003 and August 2026; the manufacturer given most often on reports is Advanced Bionics. Spellings of one product vary from report to report.

30 reports arrived in the 12 months to August 2026, down 14% from 35 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (59%), injury (40.6%) and death (0.1%); across all implant, cochlear reports (product code MCM) death is recorded in 0.1% and malfunction in 43.1%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device remains implanted (24.2%), device operates differently than expected (19.4%) and explanted (14.5%). The patient problems coded most often are hearing impairment, hearing loss and surgical procedure. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
