Otol Neurotol 2020 May 28. Epub 2020 May 28.

University of Connecticut, School of Medicine, Farmington, Connecticut.

: Microvascular decompression (MVD) is curative treatment for primary Hemifacial Spasm, in cases where a vascular loop impinges on the facial nerve. Surgical techniques for MVD may be extended to MVD of the glossopharyngeal nerve and trigeminal nerve in cases of primary glossopharyngeal neuralgia and trigeminal neuralgia. Stroke is a rare complication of these procedures that may occur during the separation of a vascular loop from nervous tissue, particularly when materials such as Teflon are used to separate the structures.

Ophthalmology.

Handb Exp Pharmacol 2020 Apr 9. Epub 2020 Apr 9.

Department of Ophthalmology, Harvard Medical School, Boston, MA, USA.

Botulinum toxin is an important treatment for many conditions in ophthalmology, including strabismus, nystagmus, blepharospasm, hemifacial spasm, spastic and congenital entropion, corneal exposure, and persistent epithelial defects. The mechanism of action of botulinum toxin for both strabismus and nystagmus is the neuromuscular blockade and transient paralysis of extraocular muscles, but when botulinum toxin is used for some forms of strabismus, a single injection can convey indefinite benefits. There are two unique mechanisms of action that account for the long-term effect on ocular alignment: (1) the disruption of a balanced system of agonist-antagonist extraocular muscles and (2) the reestablishment of central control of alignment by the binocular visual system.

Microvascular decompression: is routine postoperative CT imaging necessary?

Acta Neurochir (Wien) 2020 05 19;162(5):1095-1099. Epub 2020 Mar 19.

Department of Neurosurgery, Hannover Medical School, Carl-Neuberg-Straße 1, 30625, Hannover, Germany.

Background: Postoperative head CT imaging is routinely performed for detection of postoperative complications following intracranial procedures. However, it remains unclear whether with regard to radiation exposure, costs, and possibly lack of consequences this practice is truly justified in various operative procedures. The objective of this study was to analyze whether routine postoperative CT imaging after microvascular decompression (MVD) is necessary or whether it may be abandoned. Read More

Which factors impact on quality of life for adults with blepharospasm and hemifacial spasm?

Orbit 2020 Mar 1:1-10. Epub 2020 Mar 1.

Moorfields Eye Hospital NHS Foundation Trust, London, UK.

: Benign essential blepharospasm (BEB) and hemifacial spasm (HFS) are debilitating conditions causing spasms to the eyes and/or face and can significantly impact on quality of life (QoL). Initial research has highlighted potential factors impacting on QoL in BEB, but there remains a wealth of demographic, clinical, and psychosocial factors that may contribute to QoL but have not received attention.: Cross-sectional baseline data were collected before a single-masked randomised controlled trial from 130 adults with BEB and HFS recruited from botulinum toxin clinics at Moorfields Eye Hospital, London.

[Hemifacial Spasm Caused by Vertebral Artery Fusiform Aneurysm and the Anterior Inferior Cerebellar Artery].

No Shinkei Geka 2020 Feb;48(2):143-149

Department of Neurosurgery, National Defense Medical College Hospital.

We report a case of hemifacial spasm in which the root exit zone(REZ)of the facial nerve was compressed by both the vertebral artery(VA)aneurysm and the anterior interior cerebellar artery(AICA). A 60-year-old female had suffered left hemifacial spasm for 2 years. Three-dimensional rotational angiography with selective arterial infusion of contrast medium(3DRA-IA)revealed that a distal part of the left AICA looping at the cisternal region was contacting the dome of the left VA aneurysm, although other imaging modalities did not show the exact course of the ipsilateral AICA.

Botulinum toxin A is a kind of neurotoxin produced by clostridium botulinum, and has been applied for nearly thirty years in China.The target of BTX-A is to selectively cleave the synaptosome-associated protein of 25 KD molecular mass, commonly abbreviated SNAP-25, thereby inhibiting neurotransmitter release and causing chemodenervation. The potential application of botulinum toxin A in treating the spasmodic dysphonia, hemifacial spasm, tinnitus, rhinitis has been confirmed both in clinical practice and previous studies. Read More

The efficacy of temporary clamping of V3 with a suboccipital far-lateral approach in microvascular decompression for Hemifacial spasm associated with the vertebral artery.

Neurosurg Rev 2020 Feb 13. Epub 2020 Feb 13.

Department of Neurosurgery, NTT Medical Center Tokyo, 5-9-22, Higashigotanda, Shinagawa-ku, Tokyo, 141-0022, Japan.

Hemifacial spasm (HFS) is often caused by compression of the vertebral artery (VA) directly or indirectly as a result of other intervening vessels, so VA-associated HFS is difficult to treat. Recently, we have achieved good surgical outcomes using a far lateral approach and temporary clamping of V3 for VA-associated HFS. Herein, we present our method with an accompanying surgical video.

Hemifacial Spasm Due to Bony Stenosis of the Internal Auditory Meatus: Look Beyond the Loop.

World Neurosurg 2020 05 4;137:179-182. Epub 2020 Feb 4.

Department of Neurosurgery, Lenox Hill Hospital, New York, New York, USA. Electronic address:

Background: Hemifacial spasm (HFS) is a neuromuscular disorder resulting from cranial nerve VII compression at the root entry zone, characterized by brief, involuntary, progressive spasms of muscles on one side of face. The cisternal part of cranial nerve VII myelinated by Schwann cells is considered relatively resistant to compression. Rarely, direct compression over this segment without coexistent root entry zone compression may also result in HFS. Read More
