We compared House single-channel and Nucleus multichannel cochlear prosthesis performance in the same individual. The Minimal Auditory Capabilities (MAC) battery was used to assess performance. In most instances, the reimplanted Nucleus device was equivalent to or outperformed the original House prosthesis, and compared favorably with reported data from a group of multichannel users. Results from this case tend to support the feasibility of explanting a House device and reimplanting a Nucleus prosthesis without a measurable decrement in performance.
