BACKGROUND: Microvascular decompression (MVD) is useful treatment for Hemifacial spasm (HFS) with refractory hypertension (RHTN). Biomedical glue sling technique is a new method for MVD. In this study, we retrospectively compared the outcome of biomedical glue sling technique with traditional technique in MVD for HFS with RHTN. METHODS: A retrospective study of HFS with RHTN treated by MVD was conducted between January 2010 and June 2016. There were 155 patients underwent their first MVD at our institution...

BACKGROUND: Microvascular decompression (MVD) of hemifacial spasm (HFS) associated with the vertebral artery (VA) shows higher rates of incomplete cure and complications compared to non-VA-related HFS. METHOD: Purely endoscopic MVD for VA-associated HFS via a retrosigmoid keyhole was performed. Neurovascular conflicts by a directly offending artery and VA around the root exit zone of the facial nerve were clearly demonstrated under 30° endoscopic view without significant cerebellar retraction...

We hypothesized the filtering of sensory input from face and hand at brainstem may reorganize in hemifacial spasm (HFS) and postparalytic facial syndrome (PFS). Thus, we examined the prepulse inhibition of blink reflex (BR-PPI) in HFS and PFS. We included 12 healthy subjects, 13 patients with HFS, and 11 patients with PFS. Baseline BR, BR recovery at interstimulus interval (ISI) of 300 ms and BR-PPI at ISI of 100 ms were performed on the right sides of healthy subjects and on both sides of patients. Within-subject analysis showed baseline BR and BR-PPI were similar between asymptomatic and symptomatic sides of patients with HFS whereas BR recovery was higher on the symptomatic side...

A 19-year-old male patient presented with facial hemi-atrophy with unilateral spasms of the masseter and temporalis muscles. Ultrasound therapy and Transcutaneous Electric Nerve Stimulation therapy, known as combination therapy, were given on alternate days for 2 weeks. At the end of 2 weeks of combination therapy the patient reported a drastic reduction in the number of episodes of muscle spasm. The visual analog scale score for tenderness of the masseter and temporalis was also markedly reduced. No one has previously used combination therapy for the treatment of facial hemi-atrophy with hemi-facial spasms...

When used therapeutically, botulinum toxin (BT) has to be injected into its target tissues. All manufacturers warn not to do so in patients with oral anticoagulation to avoid haematoma. We wanted to study the haematoma frequency (HF) in patients with anticoagulation receiving BT therapy. 32 patients (16 females, 16 males, age 69.3 ± 10.0 years) with blepharospasm (n = 6), hemifacial spasm (n = 8), post-stroke spasticity (n = 16), and cervical dystonia (n = 2) received BT therapy (needle size 27G, post-injection tissue compression) whilst on anticoagulation (anticoagulation group, AG)...

BACKGROUND: Glossopharyngeal neuralgia (GPN) is an uncommon craniofacial pain syndrome caused by neurovascular conflict. Compared to trigeminal neuralgia or hemifacial spasm, the incidence of GPN was very low. Until now, little is known about the long-term outcome following microvascular decompression (MVD) process. METHODS: Between 2006 and 2016, 228 idiopathic GPN patients underwent MVD in our department. Those cases were retrospectively reviewed with emphasis on intraoperative findings and long-term postoperative outcomes...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system. The etiology is insufficiently understood. Autoimmune, genetic, viral, and environmental factors have been hypothesized. MS is twice as common in women as in men between the ages of 20 and 50 years. There is no known cure for MS. Current medical treatment helps to prevent new attacks and improve function after an attack. MS is diagnosed by physical examination, diagnostic imaging, and examination of cerebral spinal fluid...

Hemifacial spasm(HFS) is a disorder characterized by intermittent, involuntary facial muscle contractions. Microvascular decompression(MVD) is the gold treatment for HFS. The aim of this research was to discuss whether patients undergoing MVD as their initial surgical intervention experience greater spasm control than patients experiencing an MVD performed as a subsequent surgical intervention. METHODS: The study included 976 HFS patients, 452 of which (group A) underwent MVD as their initial surgical intervention and 524 of which (group B) underwent subsequent MVD...

Vascular loops in the cerebellopontine angle (CPA) and their relationship to cranial nerves have been used to explain neurological symptoms. The anterior inferior cerebellar artery (AICA) has variable branches producing vascular loops that can compress the facial cranial nerve (CN) VII and vestibulocochlear (CN VIII) nerves. AICA compression of the facial-vestibulocochlear nerve complex can lead to various clinical presentations, including hemifacial spasm (HFS), tinnitus, and hemiataxia. The formation of arterial loops inside or outside of the internal auditory meatus (IAM) can cause abutment or compression of CN VII and CN VIII...

The purpose of this study was to analyze the pathogenesis of delayed epidural hematoma (EDH) after posterior fossa surgery. Non-traumatic, non-arterial origin delayed EDH after posterior fossa surgery is extremely rare. Moreover, the pathogenesis of its supratentorial extension is obscure. Between April 1997 and June 2016, over 3300 patients underwent microvascular decompression (MVD) for neurovascular compression syndrome. The medical chart of four patients with delayed EDH were retrospectively reviewed. The median time from MVD to re-CT scan was 58 h (range, 33-100)...

The treatment of both hemifacial spasm (HFS) and blepharospasm (BEB) requires making the appropriate clinical diagnosis. Advance imaging and electrophysiologic studies are useful; however, one's clinical suspicion is paramount. The purpose of this review is to summarize current and emerging therapies for both entities. Botulinum toxin (BTX) remains the first-line therapy to treat both conditions. If chemodenervation has failed, surgery may be considered. Due to the risks associated with surgery, the benefits of this option must be carefully weighed...

Accurate and long-term transposition of offending vessels is required in microvascular decompression (MVD) for the treatment of hemifacial spasm (HFS) and trigeminal neuralgia (TN). We created ion-beam implanted of an expanded-polytetrafluoroethylene (i-ePTFE) surface to transpose offending vessels in MVD. In 13 patients with MVD, we concealed and transposed offending vessels with tape-shaped i-ePTFE, and relieved facial and trigeminal nerve compression by attaching the i-ePTFE to the dura with fibrin glue...

Hemifacial spasm (HFS) and benign essential blepharospasm (BEB) are chronic and disabling abnormal craniofacial movements that produce involuntary eyelid twitching and closure. The efficacy and safety of botulinum toxin type A (BoNT-A) injections have been accepted and widely used for the treatment of HFS and BEB. However, different injection sites may influence the effectiveness, doses, and side effects. The aim of this study is to compare the efficacy, patient satisfaction, and complications of low-dose BoNT-A injections between injection at the preseptal (PS) and the pretarsal (PT) portion of the orbicularis oculi muscle...

BACKGROUND: Microvascular decompression (MVD) is the most useful treatment for hemifacial spasm (HFS). During MVD surgery, abnormal muscle response (AMR) is widely used. ZL response (ZLR) is a new monitoring method for HFS. We compared the effect of AMR plus ZLR and simple AMR. METHODS: We performed a retrospective study of 1,868 cases of HFS treated using intraoperative monitoring between January 2013 and December 2015. Among the 1,868 cases, 896 patients underwent simple AMR monitoring and 972 underwent combined intraoperative monitoring of AMR and ZLR...
