Abstract:
Objective:To preliminarily explore the clinical significance of extended high frequency audiometry in evaluating the early hearing loss for thalassemia.Method:Pure tone audiometry(PTA) included conventional pure tone audiometry and extended high frequency audiometry were obtained on the pre and post-treatment day in 60(117 ears) patients from September in 2013 to October in 2014. Result:The averages of conventional pure tone audiometry for 117 cases were(15.72±11.62)dBHL on the pre-treatment day and(15.40±12.24)dBHL on the post-treatment day. There were no significant differences in PTA(P >0.05). But the hearing without detection rate was higher than before especially at 18 and 19 kHz. The differences of the hearing without detection rate between the pre-treatment and the post-treatment day were statistically significant(P <0.05).Conclusion:The extended high frequency may be more sensitive in evaluating the early hearing loss for thalassemia.
