目的:了解阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者的扩展高频纯音听阈情况。方法:对青年组、成年组和OSAHS组进行常频和扩展高频听阈及扩展高频各频率的检出率测试,并对检查结果进行方差分析和χ2检验。结果:青年组在4、6和8kHz处的听阈略高(P<0.05);成年组随着年龄的增长,听阈值有逐渐提高的趋势(P<0.05)。高频听阈测试显示青年组的听阈随频率的增高而增高(P<0.05),同时对于各个频率,随年龄的增长听阈也逐渐增高(P<0.05)。OSAHS组各小组在常频段就已经出现了听阈提高,且随着年龄的增长提高更明显(P<0.05),同年龄组中OSAHS组的高频听阈较成年组明显增高(P<0.05),检出率明显下降(P<0.05)。结论:OSAHS患者的常频和高频听阈均比正常同年人高,以此给OSAHS监测工作提供参考。
Objective: To investigate the extended high frequency pure tone hearing threshold in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods: The detection rate of high frequency hearing threshold and high frequency hearing rate were increased in young group, adult group and OSAHS group. The test results were analyzed by variance and χ2 test. Results: The hearing threshold of young group was slightly higher at 4, 6 and 8 kHz (P <0.05). The hearing threshold of adult group increased gradually with age (P <0.05). The high-frequency hearing threshold test showed that the hearing threshold of young patients increased with increasing frequency (P <0.05), and at each frequency, the threshold increased with age (P <0.05). In the OSAHS group, the hearing thresholds were increased in the normal frequency band and more significantly increased with age (P <0.05). In the same age group, the high-frequency hearing threshold of the OSAHS group was significantly higher than that of the adult group (P <0.05) The detection rate decreased significantly (P <0.05). Conclusion: OSAHS patients have higher frequency of common-frequency and high-frequency than the normal year-old, so as to provide reference for OSAHS monitoring.
