Hemifacial spasm (HFS) is due to the vascular compression of facial nerve at its root exit zone (REZ). Microvascular decompression (MVD) near REZ an effective and curative treatment for HFS. Since cochlear lies directly adjacent nerve, postoperative hearing loss frequently occurs during MVD surgery However, rate has decreased since introducing intraoperative neurophysiologic monitoring (IONM) b...

OBJECTIVE Precise assessment of the complex nerve-vessel relationship at the root entry zone of the trigeminal nerve is useful for planning microvascular decompression in patients with idiopathic trigeminal neuralgia. We have applied a fusion imaging technique of three-dimensional (3-D) magnetic resonance cisternography and co-registered 3-D magnetic resonance angiography (MRA) that allows virt...

plants available. For this reason we have found that Teflon provides the most effective decompression because of its pliability. If compression by the implant is the proposed cause of recurrence, why is the recurrence rate so low? Drs. Ryu and Yamamoto propose an interesting alternative technique for performing microvascular decompression by coapting the vascular loop to the dura with the use o...
