Teflon granuloma after microvascular decompression for hemifacial spasm: a case report and literature review

Abstract

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.
