言语识别率对突聋疗效评估的意义

A Preliminary Study of the Clinical Significance of Word Recognition Scores in Evaluating the Curative Effects of Sudden Hearing Loss

目的初步探讨言语识别率(word recognition score,WRS)用于评估突聋疗效的意义。方法回顾性分析11例突聋患者的临床资料,对治疗前后的纯音听阈和言语识别率进行比较。结果 11例(11耳)突聋患者治疗前、后纯音平均听阈(pure-tone average,PTA)值分别为62.27±15.36和60.23±14.32dB HL,言语识别率平均值分别为42.91%±30.83%和72.73%±26.72%;治疗前后各例患者的纯音听阈及言语识别率测试声强度差异均无统计学意义(P>0.05),而治疗后言语识别率较治疗前明显提高,差异有统计意义(P<0.05)。结论部分突聋患者治疗后虽然纯音听阈无改善,但言语识别率可有所提高;言语识别率可辅助纯音听阈评估突聋疗效。

Objective To preliminarily explore the clinical significance of word recognition scores in evalua- ting the curative effects of sudden hearing loss. Methods Pure tone averages （PTA） and word recognition scores （WRS） in 11 cases of sudden hearing loss were obtained on the pre--treatment day and the post--treatment day, and the results were compared. Results The average PTA of 11 cases was 62.27±15.36 dB HL on the pre--treat- ment day, and 60.23±14. 32 dB HL on the post--treatment day. The average WRS in 11 cases was 42.91± 30.83% on the pre--treatment day, and 72.73% ±26.72% on the post--treatment day. There were no significant differences in PTA and the intensity of the sound for testing WRS before and after treatment（P〉0.05）, and the difference of the WRS between the pre-treatment and the post-treatment day was statistically significant （P〈 0.05）. Conclusion The WRS could be used in evaluating the curative effect of sudden hearing loss, which is a sup- plement for PTA.
