中文摘要 | 對於主訴聽力損失、耳鳴或眩暈的病患,臨床聽力學可以幫助耳鼻喉科醫師診斷 病變發生的部位。常用來篩檢耳蝸後病變的傳統特殊聽力檢查包括聲微增敏感指數檢查、聽 反射閾值檢查、聽反射衰退檢查、閾上音衰退檢查和語音均衡詞實引語度檢查等。因原因不 明之感覺神經性聽力損失或眩暈來就診的病人中,曾接受上述傳統特殊聽力檢查及電腦斷層 或磁振影像檢查者共 103 名 (105 耳 )。 各種聽力檢查對耳蝸後病變診斷的靈敏度和特異 度分別為: 聲微增敏感指數檢查 67%、 66%; 聽反射閾值檢查 36%、 86%; 聽反射衰退檢查 23 %、 98%; 閾上音衰退檢查 39%、 1005; 語音均衡詞引語度檢查 rol1-over rate 23%、 93%。如果病側耳只要有 1 種特殊聽力檢查結果疑似耳蝸後病變,即視為聽力檢查 (+),則 診斷耳蝸後病變的靈敏度和特異反分別為 555、82%。 故上述傳統特殊聽力檢查,不宜只用 1 種檢查來篩檢耳蝸後病變; 如果要片檢耳蝸後病變時,最好同時施行多種傳統特殊聽力檢 查,且只要其中 1 項檢查 (+), 就要懷疑有耳蝸後病變,如此才能增加診斷耳蝸後病變的 靈敏度,而不會降低特異度。 |
英文摘要 | We evaluated the efficacy of audiological tests of 105 ears for the diagnosis of retrocochlear lesions. The audiological tests included short increment sensitivity index (SISI), acoustic reflex threshold (ART), acoustic reflex decay (ARD) , suprathrshold adaptation test (STAT) and performance intensity function of phonetically balanced words (PIPB). MRI or CT was done for all cases. Retrocochlear lesions were shown in 33 ears by MRI or CT. The sensitivity and specificity for these special tests were as following: SISI 67%/66%, ART 36%/86%, ARD 23%/98%, STAT 39%/100%, PIPB 23%/93%. According to the results, no single test was a satisfied predictor for site of lesion. Audiologic special tests should be regarded as a battery. A pattern of audiometric findings with even one test result consistent with retrochchlear abnormality should be viewed with strong suspicion, and image study should be done. |
