【摘要】： 目的:咽鼓管声测法(Sonotubometry)是利用吞咽时咽鼓管开放瞬间在管腔内通过空气传导声音的原理,对咽鼓管的开闭功能进行检测。目前国外咽鼓管声测法应用相对普及,而国外使用的声测仪价格昂贵,国内无厂家生产,亦无引进。本研究拟利用电脑软、硬件平台设计一新型实用、价廉的数码化咽鼓管声测法检查仪,供科研使用。本试验主要为将前一阶段试制的数码化声测法检查仪CHN-08提高性能后,试用于临床,测试相关数据,为下一阶段的实验做准备。方法:以试制仪器CHN-08为主要蓝本,提高扬声器的稳定性和拾音器的灵敏度,并选择门诊病人为研究对象,共计69例,136耳,记录其症状,体征及鼓室图等检查结果,用CHN-08仪器选择中心频率8kHz带宽为2kHz的窄带噪音做为信号输出,对其进行咽鼓管功能检查,并计算其咽鼓管开放的潜伏期,开放持续时间及开放时的声压增加值。结果:69例门诊病人,136耳中,咽鼓管功能正常80耳,异常56耳。筛选无临床症状及体征16耳,作为对照组,其咽鼓管开放的潜伏期24.5±20.1ms,持续时间332.5±178.9ms,声压增加值18.7±6.4dB;将患者按症状及体征分组讨论,具有耳闷胀感与否其咽鼓管功能正常率相同;鼓膜正常与内陷及穿孔均具有相同的咽鼓管功能正常率;记录鼓室图法结果66耳,将声测法与鼓室图法检测结果行配对设计的检验(kappa检验),得出两种检测方法呈中度一致。结论:1数码化咽鼓管声测法检查仪CHN-08在临床试用中,可得到患者较好的配合,与传统的鼓室图法检出一致性比较呈中度一致,灵敏度特异度较好,初步试用有一定价值,需要进一步扩大样本加以深入探讨。2声测法检查仪对于咽鼓管开放时潜伏期,持续时间及开放程度的研究是其它检查方法无法替代的。
[Abstract]:Objective: Sonotubometry is to detect the opening and closing function of eustachian tube by using the principle that the eustachian tube opens and transports through the air in the tube at the moment of swallowing. At present, eustachian tube sound measurement method is widely used in foreign countries. In this study, a new and inexpensive digital eustachian tube acoustic detector is designed on the platform of computer software and hardware for scientific research. The main purpose of this experiment is to apply CHN-08, a digital acoustic detector, which was developed in the first stage, to clinical practice, to test the relevant data, and to prepare for the next stage of the experiment. Methods: using CHN-08 as the main blueprint, the stability of loudspeakers and the sensitivity of the pickup were improved. The outpatients were selected as the study subjects. The symptoms, signs and tympanograms were recorded. A CHN-08 instrument was used to select narrow band noise with a central frequency of 8 kHz bandwidth of 2 kHz as the signal output. The eustachian tube function was examined, and the latencies, duration and increase of sound pressure of the eustachian tube were calculated. Results of 136 ears of 69 outpatients, 80 ears had normal eustachian tube function and 56 ears had abnormal eustachian tube function. 16 ears without clinical symptoms and signs were selected as control group, the latent period of eustachian tube opening was 24.5 卤20.1ms, the duration was 332.5 卤178.9msand the increased value of sound pressure was 18.7 卤6.4dB.The patients were divided into groups according to their symptoms and signs, and the normal rate of eustachian tube function was the same. The normal rate of eustachian tube function was the same as that of invagination and perforation of tympanic membrane, 66 ears were recorded by tympanogram, and the results of sound test and tympanogram were tested by paired design (kappa test), and the two methods were found to be moderately consistent. Conclusion CHN-08, a digital eustachian tube acoustic detector, can get better cooperation with the patients in clinical trial. It is moderately consistent with the traditional tympanogram method and has a good sensitivity specificity. The study of latency, duration and degree of eustachian tube opening is irreplaceable by other methods.
