Proplast is an ultra-porous composite material that has been used widely to augment the facial skeleton. In recent years, however, the popularity of this material has declined because of complications associated with its use. This paper presents a retrospective study of 36 cases treated with 88 Proplast implants at one unit over a nine-year period. The results suggest that infection of the implant is the most common post-operative complication. Infection may occur at any time following implantation and appears to be more likely when implantation is associated with an osteotomy procedure. In addition, the overall rate of infection in this study (16%) was higher than reported previously and the male-female ratio was 2:1. The possible factors involved in infection are discussed.
普罗普拉斯是一种超多孔复合材料，已被广泛用于面部骨骼的增大。然而，近年来，由于使用该材料相关的并发症，其受欢迎程度有所下降。本文对一个单位在九年期间用88个普罗普拉斯植入物治疗的36例病例进行了回顾性研究。结果表明，植入物感染是最常见的术后并发症。感染可能在植入后的任何时间发生，并且当植入与截骨手术相关时似乎更有可能发生。此外，本研究中的总体感染率（16%）高于先前报道的，男女比例为2:1。讨论了感染可能涉及的因素。
