OBJECTIVE:

To investigate the hearing at extended high frequencies of patients with obstructive sleep apnea-hypopnea 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.
