【摘要】：目的分析Gelle(蓋萊)試驗假陰性的原因。方法 2013年8月~2014年7月間因耳聾或耳鳴就診的60例(120耳)患者行純音聽閾(PTA)、聲導抗、畸變產(chǎn)物耳聲發(fā)射(DPOAE)測試和Gelle試驗,根據(jù)Gelle試驗為陰性、但純音測聽顯示為感音神經(jīng)性聾或聽閾正常則初步判定為Gelle試驗"假陰性";分析Gelle試驗陰性耳中假陰性耳數(shù)及可能原因。結果 60例(120耳)純音測聽顯示:7耳為傳導性聾,23耳為混合性聾,52耳為感音神經(jīng)性聾,38耳純音聽閾正常,這4類純音測聽結果相對應的Gelle試驗陰性耳分別為5、11、16、3耳,其中19耳判定為"假陰性"(3耳純音聽閾正常,16耳為感音神經(jīng)性聾)。110耳同時進行了聲導抗測試,鼓室圖為A、B及C型者分別為102、2、6耳,這三類鼓室導抗圖者Gelle試驗陰性者分別為22、2、4耳(其中假陰性分別為A型12耳,As型2耳,Ad型1耳,C型2耳);113耳同時進行了DPOAE測試,56耳可引出,57耳未引出,Gelle試驗陰性者DPOAE引出和未引出分別為12、17耳(其中假陰性分別為DPOAE引出10耳、未引出8耳)。結論各種類型的聽力損失患者中均存在Gelle試驗陰性者,但部分受試者可能為Gelle試驗假陰性。在診斷聽骨鏈異常時,Gelle試驗檢查只能作為輔助檢查手段,須結合病史、純音測聽、聲導抗、DPOAE等檢查綜合判斷。
[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.
