- Abstract
Using a four-channel implant system with a vocoder-based processor developed at UCSF over an extensive period of research, clinical trials of the UCSF/Storz device were initiated in February 1985 under the sponsorship of Storz Instrument Company. To date, 13 patients have been implanted with the UCSF/Storz device, 10 of whom have been fitted with their external processor and transmitter and have received at least their initial postoperative evaluations. Of these 10 patients, nine are able to use all four channels of their implant system. The device fitting/adjusting process for these patients has been remarkably easy, requiring only approximately 30 to 60 minutes. Patient results have been extremely good, with eight of the 10 patients obtaining some open-set auditory only speech understanding. Without extensive rehabilitation and training, most patients have demonstrated an improvement in speech reception over time. Lip-reading and tracking results indicate that all patients have attained an enhancement of lip-reading ability with the use of the device, suggesting that improved general communication skills have been provided for each UCSF/Storz patient.
