摘要

頭部外傷所造成的傳音性聽障，除了鼓室積血(hemotympanum)及外傷性鼓膜穿孔外，聽小骨鏈斷離亦是重要的鑑別診斷項目。聽小骨鏈斷離的形式以砧骨镫骨關節分離(incudo-stapedial joint separation)最為常見。我們在民國80年2月至民國81年9月間經歷兩例病患，皆是頭部外傷有持續性傳音性聽障，由外科轉至本科，在疑似聽小骨鏈斷離的診斷下，以鼓室探查術做聽小骨鏈重建。兩例患者術後的聽力都有顯著進步。

Conductive hearing impairment result- ing from head injury can be classified into three groups, ie a) hemotympanum, b),traumatic preforation of the eardrum and c), ossicular chain discontinuity. The most common form of ossicular chain lesion following head injury is incudo-stapedial joint separation.
We managed two patients with incudo-stapedial joint separation very successfully through exploratory tympanotomy with ossiculoplasty during the past two years. Both of them young females who had sustained bead injury without other major complication except conductive hearing impairment. They acqured signfifcant hear-ing gain postoperatively.
