你知道中耳分析儀是什么嗎?就讓<span style="color: rgb(0, 112, 192); font-size: 18px;"><strong>聆康</strong></span>來告訴你中耳分析儀又稱是什么。</p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;">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。</p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;">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。</p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;"> 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:</p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;"> 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。</p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;"> 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。</p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;"> 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)。</p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;">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 </p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;"><br /></p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;"><br /></p><p style="margin: 5px 0px; font-family: sans-serif; font-size: 16px;"><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><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><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><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;">)</span></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="" /></p>" />
