Abstract
• To find a way of improving the results of ossicular reconstruction in ears that were rendered hard of hearing by chronic otitis media, the suitability of two biocompatible materials has been investigated. After three years' experience with Proplast and two years with Plastipore, it is concluded that for ears which lack an incus and stapes arch, these materials provide results at least as good as those previously reported with homologous materials and have the advantage of easy manipulation, timesaving, and ready availability. As with all foreign material in the chronically infected middle ear, the risks of extrusion cannot be ignored. The results so far indicate that this problem can be overcome with the use of cartilage film to separate the prosthesis from the tympanic membrane. (Arch Otolaryngol 104:345-351, 1978)
