Silastic prostheses of the middle ear proved useful in the reconstruction of the chain of auditory ossicles. Following an observation period of 6 months to 6 years they led in type PORP in a group of 49 subjects to early functional positive results in 78% and late positive results in 71%. The authors tested type TORP in 56 patients with a 57% success as regards early and late results. They used pistons only in obliterated fossae of the fenestra ovalis or in case of thick immobile plates. Despite this they achieved excellent and good early and late auditory gains in 58%. Of 105 prostheses type PORP and TORP administered during the entire observation period rejection occurred only in four subjects, i. e. in 3.8%. They inserted a strip of fascia between the cap of the prosthesis and tympanic membrane.
中耳硅胶假体在听小骨链重建中被证明是有用的。经过6个月至6年的观察期,在一组49名受试者中,PORP型假体在78%的患者中取得了早期功能阳性结果,71%的患者取得了晚期阳性结果。作者对56例患者进行了TORP型假体测试,早期和晚期结果的成功率为57%。他们仅在卵圆窗窝闭塞或存在增厚固定的镫骨板时使用活塞。尽管如此,他们在58%的患者中取得了优异和良好的早期和晚期听觉增益。在整个观察期内植入的105个PORP型和TORP型假体中,仅有4名受试者(即3.8%)出现排斥反应。他们在假体帽和鼓膜之间插入了一条筋膜条。
