Teflon has been commonly used as a surgical material. In particular, Teflon has been considered suitable for microvascular decompression of cranial nerves, as it is a stable, inert substance that does not resorb or migrate. Giant cell foreign body reactions after microvascular decompression (MVD) have been reported, but this rare complication has not been well recognized. Here, we report one case of Teflon granuloma that occurred 4 years after MVD for hemifacial spasm. We discuss the cause, histopathological analysis, particular MVD surgical methods, and management of Teflon granuloma.
聚四氟乙烯一直被广泛用作外科材料。特别是，聚四氟乙烯被认为适用于颅神经微血管减压术，因为它是一种稳定、惰性的物质，不会吸收或迁移。微血管减压术（MVD）后曾有巨细胞异物反应的报道，但这种罕见的并发症尚未得到充分认识。在此，我们报告1例因面肌痉挛行MVD术后4年发生聚四氟乙烯肉芽肿的病例。我们讨论了聚四氟乙烯肉芽肿的病因、组织病理学分析、特定的MVD手术方法及处理。
