MATAS, Carla Gentile et al. Audiologic and electrophysiologic evaluation in Landau-Kleffner syndrome. Rev. soc. bras. fonoaudiol. [online]. 2007, vol.12, n.2, pp.79-85. ISSN 1982-0232.

PURPOSE: To describe the audiological and electrophysiological results of individuals with Landau-Kleffner syndrome, verifying the occurrence of peripheral and/or central auditory disorders. METHODS: Four individuals with Landau-Kleffner syndrome with ages ranging from nine to 19 years old, referred to the Auditory Evoked Potentials Laboratory of the Speech and Language Pathology and Audiology Course of the University of São Paulo, were submitted to audiologic (otoscopy, immitance measurements, pure tone and speech audiometry) and electrophysiological evaluation (short, middle and long-latency auditory evoked potentials). RESULTS: All individuals showed alterations in at least one of the evaluations performed, and it was observed a higher rate of alterations in the middle latency response (100% of the individuals showed alterations). CONCLUSIONS: A great occurrence of auditory disorders in audiological and electrophysiological evaluation of individuals with Landau-Kleffner syndrome was observed. It is emphasized the importance of the audiological investigation of these individuals, in order to verify possible relations between communication and auditory disorders in this population.
