After microvascular decompression (MVD) for hemifacial spasm (HFS), a minority of patients realize little to no relief of spasms. In some patients, the absence of relief of spasms results from incomplete or inadequate decompression of vascular compression of the facial nerve, and these patients represent excellent candidates for repeat MVD. However, in other patients, repeat MVD is not appropriate because adequate decompression and resolution of neurovascular compression, as determined by postoperative high-resolution MRI, was achieved with the initial operation. ⋯ After FNM, durable and, at least, partial relief of spasms with a relatively low complication rate was observed in most patients with HFS with incomplete relief of spasms after technically adequate prior MVD.

Microscopic microvascular decompression (MVD) of the trigeminal nerve is the gold standard surgical treatment for medically refractory classical trigeminal neuralgia. Endoscopy has significantly advanced surgery and provides enhanced visualization of the cerebellopontine angle and its critical neurovascular structures. We present our initial experience of fully endoscopic microvascular decompression (e-MVD). ⋯ Our study demonstrated that e-MVD is a safe, possibly effective method of performing MVD with the added benefit of improved visualization of the operative field for the operating surgeon and the surgical team. Larger prospective studies are required to evaluate whether performing e-MVD confers any additional benefits in long-term clinical outcome of patients with trigeminal neuralgia.

Case description: A case of a 37-year-old female patient suffering from refractory bilateral trigeminal neuralgia is presented, who underwent various interventions such as acupuncture, block therapies and even microvascular decompression without effective pain relief. ⋯ Radiosurgery by CyberKnife is not yet the first line of management in trigeminal neuralgia, however, it should be considered since several studies have managed to demonstrate an increase in the quality of life of patients and pain relief in refractory or severe cases. of said pathology.

Hemifacial spasm is a cranial nerve compression syndrome caused by the anteroinferior cerebellar artery (AICA) and posteroinferior cerebellar artery (PICA), characterized by involuntary tonic/clonic contractions of the muscles. The refractory hemifacial spasm can be treated with microvascular decompression, and multivessel compression could require more than conventional microvascular decompression. Multivessel compression may be challenging, and placement of conventional materials may not be sufficient and risks migration. ⋯ This technique offers semielastic continuous isolation of the nerve keeping it away from the offending artery. In addition, the circumferential ePTFE fit between neurovascular structures could avoid migration out of position. No cases using this technique have been reported; beyond that, we would like to illustrate this procedure, which is not widely available as a video article.
