【摘要】：目的分析Gelle(盖莱)试验假阴性的原因。方法 2013年8月~2014年7月间因耳聋或耳鸣就诊的60例(120耳)患者行纯音听阈(PTA)、声导抗、畸变产物耳声发射(DPOAE)测试和Gelle试验,根据Gelle试验为阴性、但纯音测听显示为感音神经性聋或听阈正常则初步判定为Gelle试验"假阴性";分析Gelle试验阴性耳中假阴性耳数及可能原因。结果 60例(120耳)纯音测听显示:7耳为传导性聋,23耳为混合性聋,52耳为感音神经性聋,38耳纯音听阈正常,这4类纯音测听结果相对应的Gelle试验阴性耳分别为5、11、16、3耳,其中19耳判定为"假阴性"(3耳纯音听阈正常,16耳为感音神经性聋)。110耳同时进行了声导抗测试,鼓室图为A、B及C型者分别为102、2、6耳,这三类鼓室导抗图者Gelle试验阴性者分别为22、2、4耳(其中假阴性分别为A型12耳,As型2耳,Ad型1耳,C型2耳);113耳同时进行了DPOAE测试,56耳可引出,57耳未引出,Gelle试验阴性者DPOAE引出和未引出分别为12、17耳(其中假阴性分别为DPOAE引出10耳、未引出8耳)。结论各种类型的听力损失患者中均存在Gelle试验阴性者,但部分受试者可能为Gelle试验假阴性。在诊断听骨链异常时,Gelle试验检查只能作为辅助检查手段,须结合病史、纯音测听、声导抗、DPOAE等检查综合判断。
[Abstract]:Objective to analyze the causes of false negative Gelle test. Methods from August 2013 to July 2014, 60 patients (120 ears) with deafness or tinnitus underwent pure tone threshold (PTA), acoustic impedance test, distortion product otoacoustic emission (DPOAE) test and Gelle test. According to Gelle test, 60 patients (120 ears) were negative. But if pure tone audiometry showed sensorineural hearing loss or normal hearing threshold, it was preliminarily determined as "false negative" by Gelle test, and the number of false negative ears in negative ears of Gelle test and the possible causes were analyzed. Results the pure tone audiometry of 60 cases (120 ears) showed that 23 ears were conductive deafness and 23 ears were mixed deafness, 52 ears were sensorineural deafness and 38 ears had normal pure tone hearing threshold. The negative ears of Gelle test corresponding to the four kinds of pure tone audiometry were 5111,163 ears, respectively. Among them, 19 ears were diagnosed as "false negative" (3 ears with normal pure tone hearing threshold and 16 ears with sensorineural hearing loss) .110 ears were tested for acoustic conductance at the same time. These three types of tympanograms were negative for Gelle test in 22 / 22 ears (including false negative for A type 12 ears and as type 2 ears for Ad 1 ear / C type 2 ears), and 56 ears were tested for DPOAE, 57 ears were negative for Gelle test and 57 ears were negative for Gelle test. The DPOAE elicitation and uneliction were 12 and 17 ears, respectively (10 ears were false negative for DPOAE, respectively). No 8 ears). Conclusion Gelle test is negative in all kinds of hearing loss patients, but some of them may be false negative in Gelle test. In the diagnosis of ossicular chain abnormalities, the Gelle test can only be used as an auxiliary examination method. It should be combined with medical history, pure tone audiometry, acoustic conductance and DPOAE, and so on.
