The author describes a new prosthesis used in functional rehabilitation when the chain is destroyed. It consists of a tripod part in gold, anchored in the attic region with its foot resting on the plate of the stapes. This prosthesis is covered with a piece of autologous cartilage freshly removed from the tragus which forms the junction with the tympanic membrane or covering fascia. 60 cases are presented, some with a follow-up of 4 years. All of the patients were suffering from the sequelae of chronic otorrhoea, with varying degress of destruction of the chain and tympanic membrane, leaving a mobile plate. Functional rehabilitation in one stage was good in 66% of cases, poor in more than 8% of cases and nil in 25% of cases. Tolerance of the prosthesis was comparable to that of other metallic or plastic materials used in the middle ear. The plate of the stapes would appear to tolerate the prosthesis perfectly since no secondary labyrinthisation was seen. The author suggests the use of this chondro-metallic prosthesis was a reliable means of ensuring functional rehabilitation in the presence of a post-otitic empty middle ear.
作者描述了一种在听骨链遭到破坏时用于功能康复的新型假体。它由金色的三脚架部分组成,其足部固定在镫骨板上,锚定在鼓室上隐窝区域。该假体覆盖有一块刚从耳屏取下的自体软骨,该软骨形成与鼓膜或覆盖筋膜的连接处。文中呈现了60例病例,部分病例随访了4年。所有患者均患有慢性耳漏后遗症,听骨链和鼓膜有不同程度的破坏,仅留活动镫骨板。一期功能康复效果良好的病例占66%,效果差的病例超过8%,无效果的病例占25%。该假体的耐受性与中耳使用的其他金属或塑料材料相当。镫骨板似乎能很好地耐受该假体,因为未观察到继发性迷路化。作者认为,在耳炎后中耳腔空虚的情况下,使用这种软骨 - 金属假体是确保功能康复的可靠方法。
