Abstract

The brainstem auditory evoked potentials (BAEP) of twenty-seven Myelomeningocele (MMC) patients were analyzed and compared with the results of a normal population. The longest wave V or V-I interpeak latencies were seen in patients with shunted hydrocephalus and cranial nerve defects. The shortest wave V and V-I interpeak latencies were found in patients without hydrocephalus. However, these latencies of MMC patients were significantly longer than the latencies of a normal population. Wave I latencies of all MMC subgroups were not significantly different from the results of the normal probands. It is assumed that V-I interpeak latency prolongation in MMC patients, which is related to the severity of the clinical signs of the Arnold Chiari malformation, is mostly due to an elongation of the brainstem.
