Abstract

Hemifacial spasm (HFS) is often caused by arterial compression of the root exit zone of the facial nerve. HFS caused by venous compression is rare. In this report, we describe a case of microvascular decompression (MVD) for hemifacial spasm caused by venous compression, with excellent results. The patient was a 68-year-old man with right HFS for 3 years (2019~2022). Preoperative magnetic resonance imaging (MRI) demonstrated that the facial nerve was compressed by a vein rather than an artery. We performed MVD of the facial nerve. Interposition of the vein led to sufficient nerve decompression. The HFS disappeared immediately after surgery. Preoperative diagnosis of venous compression is possible with MRI. During surgery, it is necessary to be careful not to cause venous circulation disorders because veins, unlike arteries, are sometimes difficult to move.
