Abstarct

Twelve deaf adults and two deaf children were treated with the Ineraid (formerly Symbion) four channel intracochlear implant between September 1989 and October 1991 at Addenbrooke's Hospital in Cambridge. All were post-lingually totally deaf and had found themselves beyond the reach of hearing aids. The effect of the implant upon the patients ability to lip-read was tested with the speech tracking test, BKB sentences (comparable to CID sentences) and Boothroyd word lists (comparable to NU6 word lists). All patients showed an improvement in their ability to understand speech with the help of the implant. Discrimination of speech without lip-reading was tested with Boothroyd word lists and BKB sentences, eight patients (57 per cent) demonstrated some ‘open set’ speech discrimination. The acceptability of the carbon percutaneous pedestal is discussed from the patient's, audiologist's and surgeon's points of view.
