摘要
目的分析单侧突聋患者健耳的扩展高频纯音听阈。方法对76例(年龄20～39岁,平均29.37±4.74岁)由突聋所致的单侧耳聋患者(病程≤半年60例,病程7个月～2年16例)行纯音测听及扩展高频测听,测试的气导频率范围0.125～20 kHz,并与30例(60耳)(年龄20～39岁,平均26.20±4.51岁)听力正常组比较。结果单侧耳聋组健耳扩展高频9、10、11.2、12.5、14、16、18、20 kHz各频率纯音听阈均高于听力正常组,差异均有统计学意义(P<0.05),0.125、0.25 kHz常频听阈亦高于听力正常组,差异有统计学意义(P<0.05)。与病程≤半年组相比,虽然病程7个月～2年组14、16、18、20 kHz健耳扩展高频听阈更高,但差异均无统计学意义(P>0.05)。结论单侧耳聋患者健耳可能出现隐性听力损失,建议对单侧耳聋患者的健耳常规行扩展高频听阈检测。
Objective To study the extended high-frequency pure tone hearing threshold of the healthy side ear of patients with unilateral deafness. Methods Pure tone audiometry and extended high-frequency audiometry were performed on 76 patients with unilateral deafness, the age ranged from 20 to 39 years old with an average age of 29.37 ± 4.74 years old. Among 76 cases, 60 cases had a course of hearing loss less than 6 months and 16 cases had a course of hearing loss 7 months to 2 years. The air conduction frequency ranged from 125 Hz to 20 kHz, and the results were compared with those of 30 healthy controls (60 ears), aged 20~39 years old with an average age of 26.20 ± 4.51 years. Results Compared with the normal hearing group, the extended high- frequency hearing threshold of the unilateral deafness group was reduced at 9, 10, 11.2 , 12.5 , 14 , 16 , 18 , 20 kHz ,and the difference was statistically significant ( P < 0.05 ).The constant frequency hearing threshold decreased at 0.125 and 0.25 kHz, and the difference was statistically significant ( P < 0.05 ).Compared with the normal hearing group, the full-frequency of the affected side of patients with unilateral deafness decreased at 0.125~20 kHz, and the difference was statistically significant ( P < 0.05 ).Compared with the group with a course of less than half a year, the group with a course of more than half a year, the extended high-frequency hearing threshold was worse in 14, 16, 18, 20 kHz,however, all frequency differences were not statistically significant( P > 0.05 ). Conclusion Patients with unilateral deafness may have hidden hearing loss in the healthy ear,which provides another new theoretical and experimental basis for early intervention of unilateral deafness.It is recommended to perform extended high-frequency routine testing on the healthy ear of patients with unilateral deafness.
