中文摘要 | 兩耳不對稱感覺神經性聽力損失的病人在耳鼻喉科門診相當常見,診斷此類病人 是否有耳蝸後病變,在臨床上非常重要。純音聽力圖顯示雙耳不對稱感覺神經性聽力損失且 接受腦幹聽性反應檢查和磁振影像檢查病人 46 名,男性 28 名,女性 18 名,年齡分佈由 25 歲至 78 歲。 影像檢查證實存在耳蝸後病變的病側耳 16 個,影像檢查無耳蝸後病變的 病側耳 32 個,比較此 48 個病側耳的腦幹聽性反應檢查結果和影像檢查結果。將腦幹聽性 反應無法判讀的 8 耳除外, 影像檢查顯示有耳蝸後病變且腦幹聽性反應檢查懷疑有耳蝸後 病變者 12 耳,影像檢查無耳蝸後病變且腦幹聽性反應檢查不疑耳蝸後病變者 20 耳,則腦 幹聽性反應檢查偵測耳蝸後病變之靈敏度為 80 %( 12/15 ), 特異度為 80 %( 20/25 )。對於腦幹聽性反應結果在正常值上限邊緣或偽陽性者應長期追蹤,我們建議此類病人應 於 6-9 個月後再評估其臨床變化並重複聽力檢查和腦幹聽性反應檢查。 |
英文摘要 | We experienced 46 patients with asymmetric sensorineural hearing loss. All patients received auditory brainstem response (ABR) and magnetic resonance imaging examinations. The image findings revealed 14 cases of retrocochlear lesions; including brainstem infarction, cerebello-pontine angle tumors (2 cases with bilateral tumors), cochleovestibular neuritis and arachnoid cyst. The eight ears with nonconclusive ABR results were excluded in this study. For those retrocochlear lesions, the retrocochlear signs of ABR were positive in 12 ears and negative in 3. Negative image findings were noted in 25 cases and negative ABR findings in 20. For diagnosis of the retrocochlear lesions with ABR, the sensitivity and the specificity were 80% (12/15) and 80% (20/25) respectively. Therefore, ABR is an effective and accurate tool in neurotology. |
