【摘要】：【背景】目前,短聲ABR在臨床上得到了廣泛應(yīng)用,為評估受試者聽力水平和蝸后病變的診斷提供了客觀依據(jù)。隨著聽力學(xué)的發(fā)展.新生兒聽力篩查的普遍開展,發(fā)現(xiàn)全聾和/或極重度聽力損失患兒越來越多,患兒年齡也越來越小,助聽器驗(yàn)配技術(shù)的提高,為有殘余聽力的患兒提供了一線希望。但是由于短聲ABR反映的是2000Hz~4000Hz的聽力水平[1],它完全滿足不了現(xiàn)如今臨床聽力學(xué)的發(fā)展要求。在臨床中,獲得可觀有效的殘余聽力是非常重要和急迫的,所以具有頻率特異性的短純音ABR(tone burst ABR,tb-ABR)和CE-Chirp聲誘發(fā)的聽覺穩(wěn)態(tài)誘發(fā)電位(CE-Chirp ASSR)的研究受到極大的重視。因?yàn)樗鼈兙哂锌陀^性、頻率特異性、準(zhǔn)確性高的特點(diǎn),可用于嬰幼兒早期聽力損失的診斷與評估,它們能為我們提供500Hz~4000Hz具有頻率特異性的波V閾值。故目前在國內(nèi)外都得到了廣泛的應(yīng)用[2-6]。本文將對100例極重度感音性聽力損失嬰幼兒短純音ABR與CE-Chirp ASSR的結(jié)果進(jìn)行分析,觀察它們的異同點(diǎn),以期了解短聲ABR最大輸出無反應(yīng)的情況下,是否代表全聾,它們的短純音ABR與CE-Chirp ASSR各頻率的反應(yīng)閾值是否存在,兩者的反應(yīng)閾是否存在一定關(guān)系。【目的】對100例極重度感音神經(jīng)性聽力損失嬰幼兒進(jìn)行短純音聽性腦干反應(yīng)(tone burst auditory brainstem response,tb-ABR)和CE-Chirp聲誘發(fā)的聽性穩(wěn)態(tài)反應(yīng)(auditory steady-state response,CE-Chirp ASSR)測試,對各頻率反應(yīng)閾的結(jié)果進(jìn)行總結(jié)分析,比較兩種測試方法的異同點(diǎn)�！痉椒ā繉�100例極重度感音神經(jīng)性聽力損失嬰幼兒進(jìn)行短純音ABR與CE-Chirp ASSR各頻率反應(yīng)閾值的測試,分別記錄0.5k、1.0 k、2.0 k和4.0kHz的反應(yīng)閾值,所得數(shù)據(jù)采用SPSS 11.0統(tǒng)計(jì)軟件進(jìn)行相關(guān)性檢驗(yàn)和X2檢驗(yàn)�！窘Y(jié)果】短純音ABR與CE-Chirp ASSR各頻率能引出不同程度的閾值,V波引出閾值百分比主要集中在91-100dBHL,500~4000Hz波V閾值引出率之間的相關(guān)系數(shù)分別為:0.852、0.911、0.870、0.910,所有P值0.001。CE-Chirp ASSR與短純音ABR各頻率反應(yīng)閾的卡方檢驗(yàn)P值0.05�！窘Y(jié)論】短聲ABR提示極重度感音性聽力損失嬰幼兒,其短純音ABR與CE-Chirp ASSR各頻率均有不同程度的殘余聽力,短純音ABR與CE-Chirp ASSR各頻率反應(yīng)閾引出率有很好的相關(guān)性,耳別間也無顯著性差異。
[Abstract]:Background: at present, short-tone ABR has been widely used in clinical practice, which provides an objective basis for the evaluation of hearing level and diagnosis of retrocochlear lesions. With the development of audiology. With the widespread development of neonatal hearing screening, it is found that more and more children with total deafness and / or extremely severe hearing loss are getting younger and younger. The improvement of hearing aid matching technology provides a glimmer of hope for children with residual hearing. But because short tone ABR reflects the level of 2000Hz~4000Hz, it can not meet the requirements of clinical audiology. In clinical practice, it is very important and urgent to obtain significant and effective residual hearing. Therefore, the study of frequency specific short tone ABR(tone burst ABRtb-ABR and CE-Chirp acoustic-evoked auditory steady-state evoked potentials (CE-Chirp ASSRs) has received great attention. Because they have the characteristics of objectivity, frequency specificity and high accuracy, they can be used in the diagnosis and evaluation of early hearing loss in infants and children. They can provide us with frequency specific wave V threshold of 500Hz~4000Hz. So it has been widely used at home and abroad [2-6]. In this paper, the results of short-tone ABR and CE-Chirp ASSR in 100 infants with extremely severe sensorineural hearing loss were analyzed, and their similarities and differences were observed in order to find out if the maximum output of ABR represented total deafness. Whether there is a threshold of reaction between their short-tone ABR and CE-Chirp ASSR at each frequency, [objective] to measure the short tone auditory brainstem response (burst auditory brainstem responsetb-ABR) and the auditory steady-state response induced by CE-Chirp (auditory steady-state responseCE-Chirp ASSRs) in 100 infants with extremely severe sensorineural hearing loss. The results of each frequency response threshold were summarized and analyzed, and the similarities and differences between the two methods were compared. [methods] 100 infants with extremely severe sensorineural hearing loss were tested with short-tone ABR and CE-Chirp ASSR frequency response thresholds. The reaction thresholds of 0.5 kW 1.0 kg 2.0 k and 4.0kHz were recorded, respectively. The data were tested by SPSS 11.0 statistical software for correlation test and X2 test. [results] the percentage of threshold of short tone ABR and CE-Chirp ASSR can lead to different degrees of threshold / V wave extraction mainly in 91-100dBHL5004000Hz threshold rate. The correlation coefficients between them were 0. 852U 0. 9110. 8700. 910. the chi-square test P value of all P values of 0.001.CE-Chirp ASSR and short tone ABR was 0. 05. [conclusion] short tone ABR suggests very severe hearing loss in infants and young children with sensorineural hearing loss, P = 0. 05, P = 0. 05, P = 0. 05, P = 0. 05, respectively. The frequencies of short tone ABR and CE-Chirp ASSR had different degrees of residual hearing. There was a good correlation between short tone ABR and CE-Chirp ASSR. There was no significant difference among different ears.
