Objective To investigate the effect of upper respiratory tract surgical treatments on the auditory function in adult patients with severe OSAHS. Methods The OSAHS group included 73 adult patients with severe OSAHS, and the control group included 20 non-snoring healthy people, Polysomnography monitoring (PSG), pure tone audiometry, tympa⁃nometry, auditory brainstem responses (ABR) and otoacoustic emissions (OAE) were performed in control group subjects and in patients in the OSAHS group before and 6 months after surgical treatments. Results 1) Of the 73 patients who under⁃went surgical treatments, symptoms resolved in 48 patients, significantly improved in 22 patients and somewhat improved in 3 patients at 6 months followed-up, yielding a total effective rate of 100%. 2) There were no significant differences in hear⁃ing thresholds across 250 to 4000 Hz on pure tone audiometry between the OSAHS and the control group (P > 0.05), al⁃though hearing thresholds at high frequencies showed significant differences (P<0.05). 3) The latencies of ABR waves I and V in the OSAHS group were significantly longer than in the control group (P<0.05), and showed no significant differ⁃ence before and after surgery (P>0.05) . 4) DPOAE detection rate and amplitudes at all frequencies were poorer in the OSAHS group before surgery compared with the control group (P<0.05) and showed significant changes after surgical treat⁃ ments (P < 0.05). Conclusion OSAHS can impair auditory function, probably from chronic hypoxia, which can be im⁃proved by surgical treatments in adult patients with severe OSAHS.% 目的通过成年人重度阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea-hypopnea syndrome, OSAHS)患者手术前后听觉功能检查的对照研究,了解OSAHS患者术后听力康复的情况.方法对73例手术治疗的成年人重度OSAHS患者在术前和术后6个月分别行多导睡眠监测(PSG)、纯音测听及声导抗、听性脑干电位(ABR)及耳声发射(OAE)检测.另对20例无打鼾的健康志愿者同样行上述各项检测.结果①73例OSAHS患者术后随访治疗6月,其中治愈48例,显效22例,有效3例,总有效率为100%.②两组250~4000 Hz气导纯音测听结果无显著差异(P>0.05),>4000 Hz高频听阈有显著差异(P<0.05)；术后患者主观听觉明显改善,高频区听域提高>30dB(P<0.05).③OSAHS组听性脑干反应波l、V潜伏期较对照组显著延长(P展开▼
