To investigate the function of central auditory, Speech-perception-in-noise test (SPIN test) was used to assess that whether temporal lobe epilepsy patients have central auditory processing disorders. Four audiological test were performed in 9 patients with temporal lobe epilepsy and 19 age-matched normal hearing persons as controls, which include pure tone audiometry, acoustic immittance measurement, ABR (auditory brainstem response) and SPIN test. All the temporal lobe epilepsy patients were performed by CT or MRI and diagnosed by the neurologists prior to the test. The testing materials of speech and noise in SPIN test was recorded in independent tracks and the S/N was identified by -25 dB by pre-experiment. In the test, every words were read twice and both the results were recorded. In the ABR test, only wave V latency showed longer values in the left ear, other waves like I, III and inter-peak intervals had'nt shown significant statistical differences in both ears of temporal lobe epilepsy patients. However, in the SPIN test, there's no significant statistical differences in both left and right ears of the controls by the first-time hearing (P = 0.107), and the differences showed by the second-time hearing (P = 0.048); but in the comparison of both ears in temporal lobe epilepsy patients, both time of hearing showed no significant statistical differences with P = 0.174 and P = 0.163. In additional, the SPIN recognition score of the temporal lobe epilepsy patients, whether in the fist or second time hearing, whether in the monaural or binaural models, presented significant statistical differences compared to the controls (P = 0.000). There was no statistically significant difference in pure tone audiometry and ABR test for all the groups. But the speech recognition score obtained from SPIN test of tempol lobe epilepsy patients is lower than the normal persons, which has statistically significant difference. (P < 0.001) Then we can come to the conclusion that Temporal lobe epilepsy patients had central auditory dysfunctions and SPIN test is a sensitive way to assess this abnormal.
