This paper describes the neural response telemetry (NRT) results obtained f
rom the first 30 patients tested at this centre. One hundred per cent of pa
tients tested intra-operatively had NRT responses on at least one electrode
; this compared to 82.4% of patients tested post-operatively. Reasonable co
rrelations existed between post-operative NRT thresholds and psychophysical
threshold and comfort levels, although there was too much variability for
the data to be used to set these parameters directly. Post-operative NRT th
resholds were always at levels audible to patients.
