Abstract：Objective To study the significance of word recognition scores in monitoring early hearing loss during treatment of thalassemia. Methods Pure tone audiometry (PTA) and word recognition scores (WRS) were obtained on the pre-treatment day and the day after treatment in 38 patients (76 ears) from September in 2013 to October in 2014. PTA in-cluded conventional and extended high frequencies. Results The mean PTA threshold for the 76 ears was 17.9±12.2 dB HL before treatment and 18.2±13.4 dB HL following treatment, and the mean WRS in the 76 ears was 93.6±5.9%prior to treat-ment day and 91.49 ± 8.02% after treatment. There were no significant differences in PTA before and after treatment (p>0.05), but the differences in WRS before and after treatment were statistically significant (p<0.05). Post-treatment PTA thresholds at 10, 12.5, 18, 19 and 20 kHz were elevated compared to before treatment. Conclusion WRS and extended high frequency audiometry may be valuable in evaluating early hearing loss during treatment for thalassemia.
