Abstract

It is difficult to predict the onset of clinical symptoms due to Chiari II malformation. Brainstem auditory evoked potentials (BAEPs) may be useful to select potential candidates for surgery. We studied 158 BAEPs in 134 asymptomatic children with meningomyelocele (MMC) during the first year of life. Both wave latencies (WLs) and interpeak latencies (IPLs) in asymptomatic children with MMC gradually became shorter during the first year of life. In particular, the shortening of III-V IPLs was observed in the asymptomatic children with MMC from 2 or 3 weeks to 4-6 months of age. This may be a characteristic parameter of the development of the intrinsic brainstem function in patients with MMC. Comparison of these data on BAEPs in asymptomatic children with MMC with the published data on BAEPs in normal neonates and infants showed that the maturation of brainstem function was delayed in the asymptomatic children with MMC during the first year of life. These data on asymptomatic neonates and infants with MMC could potentially be a good reference for selecting the modalities of treatment in patients with MMC associated with symptomatic Chiari II malformation.
