Saint Luke’s Midwest Ear Institute has performed its 1000th cochlear implant operation. The Kansas City, Missouri facility has been in operation since 1980. Charles Luetje performed the procedure on 73-year-old Dan Neuenswander. He received a new hybrid implant as part of a national clinical trial. It's smaller than a traditional implant, and inserted only partway into the cochlea, replacing high pitches while leaving the patient’s natural low-pitch hearing intact.
