中文摘要 | 頭部外傷所引起的傳音性聽力障礙,大致可分為三類,除了鼓室積血(hemotympanum)和外傷性耳膜穿孔(traumatic eardrum perforation)之外,聽小骨鏈斷離(ossicular chain discontinuity)亦是我們要考慮的項目。 聽小骨鏈斷離的型式以砧骨磴骨關節分離(incudostapedial joint separation)最為常見。在過去二年內,我們曾經歷過二例聽小骨鏈斷離的病例,她們均為年輕女性,在車禍頭部外傷後伴有持續性的聽力障礙,在懷疑聽小骨鏈斷離的診斷下,於外科病情穩定後,以中耳探查術做聽小骨鏈重建,兩名患者術後聽力皆有顯著改善。 |
英文摘要 | In addition to hemotympanum and traumatic eardrum perforation, traumatic ossicular chain discontinuity should also be considered in the differential diagnosis of conductive hearing impairment resulting from head injury. The most common form of these ossicular chain lesions following head injury is incudostapedial joint (I-S joint) separation. We sucessfully managed two patients with I-S joint separation resulting from head injury through exploratory tympanotomy with ossiculoplasty within the recent 2 years. Both were young females who had sustained head injury resulating from traffic accident with the sequelae of persistent hearing impairment. They both gained significant hearing improvement postoperatively. |
