Patterns of auditory nerve and brainstem-evoked responses (ABR) in different types of peripheral hearing loss.
Auditory brainstem response (ABR) recordings were made in different types of peripheral hearing loss (sensorineural, conductive, and mixed). Scatter diagrams were constructed by plotting different expressions of the hearing loss (audiometric and electrophysiologic) against the obtained wave latencies and for these two sets of variables, correlation coefficients and the parameters of the regression equation were calculated. Consideration is given to the possibility of diagnosing the type of peripheral hearing loss by correlating wave latencies and the electrophysiologic (ABR) threshold.
