Abstract:
The brain-stem auditory evoked potentials(BAEPs) were evaluated in 5 adult patients with various posterior fossa lesions in the diagnosis and during operative manipulation to determine whether this technique was capable of providing useful information to the operating surgeon. The BAEPs were not only very sensitive noninvasive screening test in the diagnosis of small acoustic neuroma, but also very to preserve hearing during dissection of the tumor from the auditory nerve. In case of large acoustic neuroma, intraoperative BAEPs were helpful to monitor the effect of an operative procedure even on the contralateral brain-stem auditory pathway. Besides BAEP monitoring was also useful for operative manipulation in the region of the 8th nerve such as microvascular decompression of cranial nerve.
