Microanatomy of the central myelin portion and transitional zone of the oculomotor and abducens nerves.

Folia Morphol (Warsz) 2022 Jun 13. Epub 2022 Jun 13.

Department of Anatomy, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand.

Deep Learning Based Real-Time Semantic Segmentation of Cerebral Vessels and Cranial Nerves in Microvascular Decompression Scenes.

Cells 2022 Jun 2;11(11). Epub 2022 Jun 2.

Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, Changchun 130033, China.

Automatic extraction of cerebral vessels and cranial nerves has important clinical value in the treatment of trigeminal neuralgia (TGN) and hemifacial spasm (HFS). However, because of the great similarity between different cerebral vessels and between different cranial nerves, it is challenging to segment cerebral vessels and cranial nerves in real time on the basis of true-color microvascular decompression (MVD) images. In this paper, we propose a lightweight, fast semantic segmentation Microvascular Decompression Network (MVDNet) for MVD scenarios which achieves a good trade-off between segmentation accuracy and speed.

Ingenuity using 3D-MRI fusion image in evaluation before and after microvascular decompression for hemifacial spasm.

Surg Neurol Int 2022 20;13:209. Epub 2022 May 20.

Department of Neurosurgery, Yamagata City Hospital Saiseikan, Yamagata, Japan.

Background: Hemifacial spasm (HFS) is most often caused by blood vessels touching a facial nerve. In particular, responsible vessels compress the root exit zone (REZ) of the facial nerve. Although we recognize these causes of HFS, it is difficult to evaluate the findings of precise lesion in radiological imaging when vessels compress REZ. Read More

Lateral Suboccipital Infrafloccular Approach with Extensive Arachnoid Dissection for Vertebral Artery-Associated Hemifacial Spasm: Two-Dimensional Operative Video.

World Neurosurg 2022 Jun 3;164:305. Epub 2022 Jun 3.

Department of Neurosurgery, Hamanomachi Hospital, Fukuoka, Japan.

Hemifacial spasm (HFS) is generally caused by compression of the root exit zone (REZ) of the facial nerve by the anterior and posterior inferior cerebellar arteries and occasionally the vertebral artery (VA). Owing to its large caliber and high stiffness, microvascular decompression (MVD) for VA-associated HFS is considered more difficult, and the result is worse than for HFS not associated with the VA. Therefore, a safer, more reliable MVD is required for VA-associated HFS. Read More

Factors Related to Hemifacial Spasm Recurrence in Patients Undergoing Microvascular Decompression-A Systematic Review and Meta-Analysis.

Brain Sci 2022 Apr 29;12(5). Epub 2022 Apr 29.

Department of Neuroscience, Neurosurgery Section, Università Cattolica del Sacro Cuore, 00168 Rome, Italy.

There is a lack of knowledge about the factors associated with the recurrence of hemifacial spam (HFS) following an initially successful microvascular decompression (MVD) surgery. The aim of the present study was to systematically review the pertinent literature and carry out a meta-analysis of factors linked to HFS recurrence in patients undergoing initially successful MVD treatment. An online literature search was launched on the PubMed/Medline and Scopus databases. Read More

Therapeutic Approach to Botulinum Injections for Hemifacial Spasm, Synkinesis and Blepharospasm.

Toxins (Basel) 2022 05 23;14(5). Epub 2022 May 23.

Department of Neurology, Shaare Zedek Medical Center, Jerusalem 9103102, Israel.

The aim of this study was to show our therapeutic outcome of botulinum injection to the facial muscles and thereby to find the best therapeutic concept which should be embraced. The decision to treat the lower eyelid with 1-point or 2-points injection was randomly taken as there is no consensus regarding this debate. Injections of the lateral end of the upper eyelid were performed more laterally to the conventional injection point, just lateral to the conjunction of the upper and lower eyelids. Read More

J Neurosurg Anesthesiol 2022 May 17. Epub 2022 May 17.

Departments of Anesthesiology.

Background: The lateral spread response (LSR) is an electromyography feature of hemifacial spasm; intraoperative reduction in the LSR is associated with positive surgical outcomes. This study examined the effects of different minimum alveolar concentrations (MACs) and durations of sevoflurane inhalation on the LSR.

The "ePTFE Sleeve" for Microvascular Decompression of the Facial Nerve.

World Neurosurg 2022 May 13;164:240. Epub 2022 May 13.

Department of Neurosurgery, Hospital Juárez de México, Avenido Instituto Politecnico Nacional, Magdalena de las Salinas, Gustavo A. Madero, Mexico City, Mexico.

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. Read More

Common trunk anomaly of the anterior and posterior inferior cerebellar artery in hemifacial spasm.

Acta Neurochir (Wien) 2022 May 7. Epub 2022 May 7.

Department of Neurosurgery, Koto Memorial Hospital, 2-1 Hiramatsu-cho, Higashiohmi-shi, Shiga, 527-0134, Japan.

Background: The common trunk anomaly of the anterior and posterior inferior cerebellar artery (APC) is a variant artery that causes a hemifacial spasm (HFS). The anatomical characteristics include a large diameter of the trunk and the existence of the bifurcation near the facial nerve root entry zone (REZ). Despite APC being encountered at a constant rate in microvascular decompression (MVD), the anatomical and technical issues of transposing APC have not been entirely focused on yet. Read More

Macrovascular Decompression for Hemifacial Spasm: Three-Dimensional Operative Video.

World Neurosurg 2022 Apr 26;164. Epub 2022 Apr 26.

Department of Neurosurgery, Hofstra Northwell School of Medicine, Manhasset, New York, USA. Electronic address:

In 1%-2% of patients with symptomatic vascular compression of a cranial nerve, the compression may be due to a tortuous dolichoectatic vertebrobasilar artery. The most common technique used for microvascular decompression relies on the placement of a polytetrafluoroethylene (Teflon) pledget or other buffer between the root of the nerve and the offending vessel loop, thereby decompressing the cranial nerve. In cases of macrovascular compression by a large tortuous artery, these buffering techniques fail to produce lasting results with risk for cranial nerve compression-related deficit, specifically the facial nerve.

Microvascular decompression for pediatric-onset hemifacial spasm: case series and literature review.

Childs Nerv Syst 2022 Apr 13. Epub 2022 Apr 13.

Department of Neurosurgery, XinHua Hospital (The Cranial, Nerve Disease Center of Shanghai), Shanghai JiaoTong University School of Medicine, Shanghai, 200092, China.

Objectives: Pediatric hemifacial spasm has been rarely reported in the literature, which contains only 44 cases. Although microvascular decompression (MVD) has been widely regarded as effective therapy for hemifacial spasm, the etiology and surgical treatment of pediatric patients are seldom reported. We report our experience with MVD for pediatric hemifacial spasm patients and review the literature with emphasis on the difference from adults. Read More
