In 45 patients with absence of the stapedial arch, including 24 with a history of radical surgery and without ossicles, the head of an allograft stapes was placed on the patient's footplate and on top of this an incus body, either as allograft or autograft. The results of this assembly, judging by different methods of analysis, are the same as in 45 ears having approximately the same pathologic condition treated by an autograft or allograft incus as the columella between the footplate and eardrum. The allograft stapes-incus assembly is an alternative method to the commonly used incudal columella, particularly in patients previously subjected to radical surgery in whom all ossicles are absent.
在45例镫骨弓缺失的患者中，包括24例有根治性手术史且无听小骨的患者，将同种异体镫骨的头部置于患者的镫骨足板上，并在其上方放置砧骨体，砧骨体可为同种异体或自体。通过不同分析方法判断，这种组合的结果与45只耳朵相同，这些耳朵具有大致相同的病理状况，采用自体或同种异体砧骨作为镫骨足板和鼓膜之间的柱状体进行治疗。同种异体镫骨 - 砧骨组合是常用砧骨柱状体的替代方法，特别是在先前接受过根治性手术且所有听小骨均缺失的患者中。
