你知道中耳分析儀是什么嗎？就讓聆康來告訴你中耳分析儀又稱是什么。中耳分析儀又叫聲導抗測聽儀。是利用一個或多個頻率的探測音來測試中耳系統(tǒng)的功能，從而判斷中耳的健康狀況，探測音的準確性直接影響中耳聲納聲導和聲導納測試結(jié)果的準確性。中耳分析儀可以對中耳炎癥、咽鼓管功能及鐙骨肌反射進行了解與診斷，一般用于傳音性聾，骨氣導間距大于15dB等病員的檢查。　兒童選配助聽器時，最好常規(guī)測定聲阻抗，由于兒童因解剖原因最易出現(xiàn)中耳炎所致聽力障礙。下面是臨床聲導抗測聽的結(jié)果：　　A 型：正常型，即峰壓點位于± 50daPa 之間，峰值 0.3-1.65ml ，兒童則為 0.35-1.4ml。　　B 型：平坦型，提示鼓膜及中耳系統(tǒng)不活動，如中耳積液、探頭耵聹阻塞等。　　C 型：鼓室負壓型，圖表現(xiàn)為峰壓點位于 -100daPa 以外，提示中耳頻壓狀態(tài)。常見原因多為中耳為咽鼓管不通；鐙骨肌的反射閾強度正常耳為10-100 dBL，平均為85dB  <img anchorname="OLE_LINK3" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" /><img anchorname="OLE_LINK2" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" /><a href="https://www.linkind.top/" target="_blank" _href="https://www.linkind.top/" style="font-size: 24px;"><span style="font-size: 20px; font-family: 宋體; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">聆康聽力集團官網(wǎng)：<span style="font-size: 20px; font-family: Arial, sans-serif; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">www.linkind.top(<span style="font-size: 20px; font-family: 宋體; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">點擊跳轉(zhuǎn)<span style="font-size: 20px; font-family: Arial, sans-serif; color: red; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">)</a><img anchorname="OLE_LINK4" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" /><img anchorname="OLE_LINK5" class="anchorclass" style="max-width: 50%; background: url("/public/plugins/Ueditor/themes/default/images/anchor.gif") left center no-repeat scroll transparent; cursor: auto; display: inline-block; height: 16px !important; width: 15px !important;" alt="" />" />
