Early auditory evoked potentials in infants with craniofacial malformation

The early auditory evoked potential was evaluated for 10 infants with craniofacial malformation between the ages of 1--20 months. The stimuli were broadband clicks presented at 60 db re normal adult threshold. Resultant data were compared to the normative data of Salamy and McKean (EEG clin. Neurophysiol., 1976, 40, 418-426). Peripheral transmission times suggest varying degrees of hearing loss for 8 of the 10 infants; central transmission times were delayed for 6 of the 10 infants. The results suggest that brainstem auditory development may be altered in the infant population exhibiting craniofacial malformation.
