Purpose
to describe the audiological and electrophysiological findings of a group of patients with autistic spectrum disorder.
Methods
this is a cross-sectional descriptive study. Nine patients with autistic spectrum disorder participated in these study and it was performed the audiological and electrophysiological evaluation. Results were expressed as descriptive statistics.
Results
all patients presented audiometric threshold within normal standards. Eight patients had type A tympanogram and one had type C. It was observed the presence of distortion product otoacoustic emission responses in all patients. The results of brainstem auditory evoked responses indicated the integrity of auditory pathways.
Conclusion
the population studied showed results consistent with normality in behavioral and electrophysiological assessment of hearing. Because there is no consensus, in specialty literature, regarding the audiological findings in this population, particularly with regard to electrophysiological assessment of auditory processing, we would like to suggest the performance of new studies.
