目的 研究低頻傳導性聽力損失與中耳共振頻率的相關性.
方法 納入84例參與者,測量其共振頻率,并用金標準測試.用ROC曲線測試診斷低頻傳導性聽力損失的最佳分界點,用Levene’s測試低頻傳導性聽力損失組與聽力正常組間共振頻率的差異.
結果 傳導性聽力損失和聽力正常組的共振頻率來自不同的總體.理想的分界點為850 Hz和1 050 Hz.共振頻率在850 Hz~1 050 Hz之間認為是正常的.當共振頻率小于850 Hz時,檢驗出傳導性聽力損失的效能較高,當共振頻率大于1 050 Hz時,檢驗出傳導性聽力損失的效能較低.
結論 當共振頻率小于850 Hz時,可以推斷有傳導性聽力損失;當共振頻率大于1 050 Hz時,檢驗效能較低.這可能與共振頻率受多因素影響有關.當共振頻率高于1 050 Hz時,耳鼻咽喉科醫師和聽力學家在解釋共振頻率的結果時必須慎重.
