Resting-state functional magnetic resonance imaging (fMRI) has been used to detect the alterations of spontaneous neuronal activity in various neurological and neuropsychiatric diseases, but rarely in hemifacial spasm (HFS), a nervous system disorder. We used resting-state fMRI with regional homogeneity (ReHo) analysis to investigate changes in spontaneous brain activity of patients with HFS and to determine the relationship of these functional changes with clinical features. Thirty patients with HFS and 33 age-, sex-, and education-matched healthy controls were included in this study...

Microvascular decompression (MVD) of cranial nerves has become an established treatment for trigeminal and (vago)glossopharyngeal neuralgia and for hemifacial spasm. The authors present the case of a 64-year-old man who had a 3.5-year history of severe, drug-resistant hemibody pain with sensory and autonomic disturbance. The ipsilateral trigeminal, cochlear, and glossopharyngeal function also was affected. The contralateral posterior inferior cerebellar artery was seen on magnetic resonance imaging to be indenting the caudal medulla anterolaterally, causing displacement...

BACKGROUND: Traditionally, tinnitus accompanied by hemifacial spasm has been considered a type of hyperactive neurovascular compression syndrome that is similar to hemifacial spasm alone because of the anatomically close relationship between the facial nerve and cochlear nerve as well as the hyperactive clinical nature. METHODS: Participants were 29 subjects who presented with hemifacial spasm and neuroradiological evidence of vascular compression of the cranial (facial/cochlear) nerve...

Congential hemifacial spasm is a rare condition that is characterized by the occurrence of paroxysmal hemifacial contractions in neonates. We review the clinical, neurophysiological, neuroimaging, and histopathological findings, as well as the differential diagnosis, therapeutic approach, and outcome of all the described cases. Moreover, we report two new cases including the ictal video-electroencephalography recordings. Hemifacial spasm starts early in life, and is characterized by unilateral, involuntary, irregular tonic or clonic contractions of muscles innervated by the seventh cranial nerve...

The purpose of this study was investigate functional alteration in the brains of patients with hemifacial spasm using positron emission tomography (PET). We studied cerebral glucose metabolism using PET with (18) F-fluorodeoxyglucose in 13 patients with right lateral hemifacial spasm and 13 with left lateral hemifacial spasm. All patients underwent 2 PET scans before treatment (active state) and after treatment (suppressive state) with the botulinum neurotoxin type A. At the time of the PET scans, the severity of the spasm was rated according to the Jankovic Disability Rating Scale...

We present a male infant with hemifacial seizures refractory to antiepileptic medication. Hemifacial spasms around the left eye were frequent during wakefulness and sleep since birth. He also had mild psychomotor retardation. Magnetic resonance imaging (MRI) revealed a large tumor in the left middle cerebellar peduncle. Ictal single photon emission computed tomography (SPECT) and ictal (18)F-fluorodeoxyglucose [(18)F-FDG] positron emission tomography (PET) revealed hyperperfusion and hyper glucose metabolism at the tumor...

Peripheral injury of the facial nerve is a frequent disorder. It is a stressful situation for the patient and it is functionally hazardous for the cornea. Facial palsy is due to a lesion involving the facial pontine nucleus or the nerve trunk in its route from the pontocerebellar angle to the parotid. The idiopathic facial paralysis or Bell's palsy (BP) is the most common cause but acute facial palsy can also be due to tumors. A rigorous clinical history and examination must be performed to guide the additional biological, radiological and cochleovestibular investigations in order to reach the diagnosis...

On the occasion of my retirement as head of the Neurochirurgische Universitätsklinik Zürich on 31. May 2007, the changing aspects of neurosurgery in diseases dealt with and in their treatments during the last 70 years (from the foundation of the department by Prof. Krayenbuehl in 1937 successed by Prof. Yaşargil and later on by myself.) were presented. Number of surgical procedures were 1,000 times per year during the interval and the busiest era was that of Prof. Krayenbühl, in which it amounted to as much as 1,500 at the maximum...

The objective of this case study was to describe the clinical and electroencephalography (EEG)/functional magnetic resonance imaging (fMRI) data of a case of isolated hemifacial spasm due to epilepsia partialis continua in a 59-year-old man with abnormal hemifacial movements that disappeared during voluntary tasks, were absent during sleep, and responded to carbamazepine. His neurological examination was normal; EEG revealed right inferior frontal epileptiform discharges. EEG/fMRI demonstrated increased blood oxygenation level-dependent contrast in the right inferior and middle frontal gyri corresponding to the contralateral motor and premotor cortex responsible for facial movements (BA 44, 45, 45, 9), with widespread BOLD signal deactivations suggestive of epileptic network involvement despite a very focal epileptogenic process...

The level of success of neurovascular decompression in ponto-cerebellar angle for hemifacial spasm and trigeminal neuralgia has already established the reality of the pathology to explain such symptoms. However, cochlear nerve compression syndrome by vascular loop is still a controversial topic. We have performed a retrospective cases review with long-term follow-up (5-7 years) concerning the results of microvascular decompression surgery of the cochlear nerve via an endoscopy assisted retrosigmoid approach on 15 patients suffering from unilateral incapacitating tinnitus with abnormal auditory brainstem response and an offending vessel on magnetic resonance imaging...

Bilateral hemifacial spasm (HFS) is a rare movement disorder posing diagnostic doubt with other facial dyskinesias. In this report, we describe clinical, radiological and therapeutic features of 10 patients with bilateral HFS. The prevalence of bilateral HFS in our sample was of 2.6%. Clinical characteristics of our patients did not differ from the classic features of unilateral cases. The mean latency for contralateral facial nerve involvement was of 33.3 months. In only one case a vascular abnormality was seen...

The aim of the study was to clarify the relationship between neurovascular compression of the rostral ventrolateral medulla and arterial hypertension in patients with primary hemifacial spasm. We enrolled 82 patients with primary hemifacial spasm and 82 age- and sex-matched magnetic resonance imaging (MRI) controls of the posterior cranial fossa. Neurovascular compression of the rostral ventrolateral medulla was assessed by MRI, and its association with arterial hypertension was investigated. No significant differences were found in prevalence of arterial hypertension between patients with primary hemifacial spasm and control subjects (39...

A 53 year old lady with diabetes mellitus presented with right hemi-facial spasm (HFS). Brain MRI Scan revealed extensive pan-sinusitis and mild bilateral mastoiditis. She responded well to intravenous ceftriaxone therapy and the hemifacial spasm resolved. The symptoms of hemifacial spasm and pain over the right cheek and peri-orbital area recurred after three weeks. She was admitted to hospital for Functional Endoscopic Sinus Surgery (FESS); following findings on repeat para-nasal sinus CT-Scan. Several reviews over six month's period revealed complete resolution of hemi facial spasm symptoms save for mild intermittent right blepharospasm; particularly on exposure to wind...

BACKGROUND: Microvascular compressions of the cochlear nerve can lead to hearing loss. Due to the tonotopic organization of the cochlear nerve any focal compression of the cochlear nerve will result in a frequency specific hearing loss. Decompressing the cochlear nerve could result in a frequency specific hearing improvement, without improving overall hearing. METHOD: Thirty one patients underwent microvascular decompression operations of the vestibulocochlear nerve for vertigo or tinnitus...
