新聞專題(上):專訪耳鼻喉專科醫生鄭應平

Thursday, August 2nd, 2018

有時候,當你感到有眩暈、嘔吐的症狀時,身邊的人就會問:“你是不是耳水不平衡?”究竟耳水不平衡是怎麼一回事?而怎樣的感覺才能被稱為“眩暈”呢? 據了解,眩,是指目眩,眼花繚亂;暈,是指頭暈,頭部轉動不定。兩者若同時出現,便成為“眩暈”。 其實,我們的耳朵不只是負責聽覺的器官,它還負責身體的平衡,而引致眩暈的成因,有部分是由內耳問題所產生的。 耳鼻喉專科醫生鄭應平表示,眩暈是常見的一種疾病,且病因也有很多種。有時候,當你有眩暈的症狀並不一定是耳水不平衡所引起,或許是其他因素所引起的。 “因此,當你出現眩暈伴隨嘔吐現象時,雖可以掛耳鼻喉科瞭解內耳平衡是否有問題,但如果你覺得頭暈、嘔吐及身體半邊沒力(恐有中風之虞),又或是若感到頭暈及心跳異常加速(恐有心臟病問題),病患應前去緊急部門做檢查,先排除重症再說。” 所謂的耳水不平衡,可被稱為良性陣發型姿勢性眩暈(BPPV),它其實是一種內耳造成的問題。當你的頭部移動到某特定位置時會發生眩暈,這可能使你覺得頭昏眼花、失去平衡及感到噁心。 那又是什麼引起良性陣發型姿勢性眩暈?鄭應平透露,耳石是控制人身體平衡的重要器官,正常的耳石應在三個半規管中。 “當在我們頭部的移動下,耳石在球囊橢圓囊(Utricle)中,一旦耳石落下來並跑到三個半規管(Semicircular canals),就會發生良性陣發型姿勢性眩暈。” 他指出,耳石脫落是最常見的眩暈原因之一,當患者在移動頭部或改變姿勢時會感到眩暈,但有許多病人的病因是不明的。俗稱的耳水不平衡患者,較多為中年人,男女機率同等,且也沒有所謂的職業限制。 _________________________ Epley手法: 是最常見的一種周圍性眩暈,病變多在後半規管。以Epley手法可減輕或緩解眩暈不適症狀。(配合power point…
