Title: Effects of chronic electrical stimulation on patients using a cochlear prosthesis. Author: Waltzman SB, Cohen NL, Shapiro WH. Journal: Otolaryngol Head Neck Surg; 1991 Dec; 105(6):797-801. PubMed ID: 1787969. Abstract: Eighteen patients using the Nucleus multichannel cochlear prosthesis underwent annual evaluations for electrical thresholds, dynamic range, and speech recognition abilities for a period of 1 to 5 years. Results revealed no correlation between length of usage of a cochlear implant and electrical thresholds. The dynamic range was initially wider in the patients with open-set speech recognition, but narrowed in subsequent years. There was a correlation between length of deafness and postoperative performance.[Abstract] [Full Text] [Related] [New Search]
