阻塞性睡眠呼吸暂停低通气综合征纯音听阈检测结果分析

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阚情况。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χ^2检验。结果：青年组在4、6和8kHz处的听阙略高（P〈0．05）；成年组随着年龄的增长，听阚值有逐渐提高的趋势（P〈0．05）。高频听阚测试显示青年组的听阚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组的高频听阚较成年组明显增高（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阚均比正常同年人高，以此给OSAHS监测工作提供参考。

Analysis of the hearing of patients with obstructive sleep apnea-hypopnea syndrome

OBJECTIVE: To investigate the hearing at extended high frequencies of patients with obstructive sleep apnea-hyponea syndrome (OSAHS). METHOD: The youth group, adult group and OSAHS group were tested with pure tone audiometry and high frequency audiometry, and the response ratio was calculated. The results were statistically analysed with chi2-test and ANOVE. RESULT: In youth group, thresholds of pure tone audiometry in 4, 6, 8 kHz were increased slightly (P < 0.05). The hearing lose gradually with aging in adult group (P < 0.05). The high frequencies thresholds increased with the frequency increasing in youth group (P < 0.05). For each frequencies, the thresholds increased with aging (P < 0.05). At common frequencies hearing loss appeared in OSAHS group (P < 0.05), and more with aging (P < 0.01). The high frequency thresholds increased obviously when OSAHS group comparing with the adult group (P < 0.01), and the indicating ratio decreased obviously (P < 0.05). CONCLUSION: The common and high frequency thresholds in OSAHS group of the same age were worse than that of the adult group and it could provide the reference for the clinic.
