Simultaneous recording of cochlear and brain stem potentials in man

Summary

In our clinic brain stem potentials recorded by a nonsurgical method have been used as a routine audiometric test for 4 years. The procedure has proved to be easier than ECoG and gives nearly the same information about cochlear and middle ear function if there is no VIIIth nerve or brain stem damage. For topical diagnosis of the lower auditory pathway additional recording of BCoG is necessary.

For a case of combined hearing loss corresponding audiometric results obtained by these two methods are demonstrated. In a case of an Apallic Syndrome brain stem potentials are found only for high intensity clicks, and latencies are abnormally increased. The cochlear potentials simultaneously recorded from the promontory are quite normal. So damage of the brain stem is confirmed.
