Lateralisation of sound in temporal-lobe epilepsy: Comparison between pre- and postoperative performances and ERPs

► Sound-lateralisation performance of temporal-lobe epilepsy (TLE) patients and the amplitudes of their N1 and P2 responses to auditory directional stimuli proved to be lower than those of the normal population. ► Only insignificant effects of anterior temporal lobectomy on TLE patients' sound-lateralisation performance and on their auditory directional ERPs were noted. ► Standard audiometry should be supplemented with detailed directional hearing tests in TLE patients.
