Blepharospasm, the most frequent feature of cranial dystonia, and hemifacial spasm are two involuntary movement disorders that affect facial muscles. The cause of blepharospasm and other forms of cranial dystonia is not known. Hemifacial spasm is usually due to compression of the seventh cranial nerve at its exit from the brain stem. Cranial dystonia may result in severe disability. Hemifacial spasm tends to be much less disabling but may cause considerable distress and embarrassment. Patients affected with these disorders are often mistakenly considered to have psychiatric problems. Although the two disorders are quite distinct pathophysiologically, therapy with botulinum toxin has proven very effective in both. We review the clinical features, proposed pathophysiologic features, differential diagnosis and treatment, including the use of botulinum toxin, of cranial dystonia and hemifacial spasm. 相似文献

Six patients noted facial asymmetry after botulinum toxin injection for hemifacial spasm. Each patient was injected on the side contralateral to the spasms with 10 to 15 IU over the zygomatic major and minor muscles. Each patient noted improvement in facial symmetry in the resting position and dynamic facial movements. Five of the six patients desired this approach with subsequent injections. This injection method variation proved helpful in the managing of hemifacial weakness created by botulinum A toxin for this condition. 相似文献

Vascular cross-compression of cranial nerves has been proposed as the cause of cranial neuropathies, including trigeminal neuralgia and hemifacial spasm. Over the last decade we have used microsurgical vascular decompression to treat these two disorders. Results in 50 patients treated for trigeminal neuralgia have been excellent in 42, good in 5 and poor in 2; and 1 patient was cured after a second operation. Results in 22 patients treated for hemifacial spasm have been excellent in 18, good in 2 and fair in 1. One patient died. There were no late recurrences of symptoms.The pathophysiological mechanisms of trigeminal neuralgia and hemifacial spasm remain unknown. 相似文献

In this case report, a 50-year-old female with a chronic blepharospasm (spasmodic winking) around both eyes was treated with 17 sessions of electromyographic (EMG) feedback. EMG level and spasm frequency were monitored during baseline, placebo, and feedback treatment sessions. There was a marked decrease in both EMG level and spasm frequency, which generalized to her everyday life. Improvement was maintained at a 4-month follow-up. 相似文献

Five cases of idiopathic hemifacial spasm have been successfully treated by operative manipulation of arterial branches compressing the VIIth nerve in the posterior fossa. Terminology, clinical presentation, pathology and therapeutic approaches to hemifacial spasm are discussed. Hearing loss due to operatively induced vascular impairment of the inner ear, a complication in our first case, should be avoidable.Our experience indicates that hemifacial spasm reflects mild chronic compression of the facial nerve. The proposed mechanism is transaxonal excitation between afferent and efferent fibers. 相似文献

Our goal was to investigate the characteristics of the auditory brainstem reflexes in patients with hemifacial spasm (HFS) and postparalytic facial syndrome (PFS).The spasm activities and responses by supraorbital and auditory stimuli were recorded from the orbicularis oculi, the posterior auricular and the mentalis muscles in 27 HFS and 21 PFS patients. The results were compared with those of 20 controls.Blink reflex (BR) was obtained by supraorbital stimulation in normal controls and on both sides of HFS and PFS patients whereas sound evoked bilateral auditory blink reflex (ABR) in 96.3%, 90.5% and 100%, respectively. Both BR and ABR showed synkinetic spread on symptomatic sides in all patients. The posterior auricular muscle response (PAMR) was observed bilaterally in 59.3%, 42.9% and 75.0% of groups, respectively. However, there was no synkinetic spread of PAMR.Since PAMR does not show synkinetic spread even in the presence of synkinetic spread of ABR and BR, we may suggest that a distal origin may be responsible of the synkinetic spread, or PAM is probably governed by a smaller nucleus in the brainstem. Thus it may be speculated that its excitability is insufficient to stimulate the ABR nucleus, whereas the reverse process is possible. 相似文献

Neurovascular free-muscle transfer to treat facial paralysis associated with hemifacial microsomia 总被引:2,自引:0,他引:2
Despite the wide spectrum of hemifacial microsomia manifestations, treatment mainly focuses on mandible and ear abnormalities, rather than on facial paralysis. In fact, the surgical treatment of facial paralysis associated with hemifacial microsomia is quite underdeveloped, because the degree of paralysis is frequently incomplete or partial. Timing and type of surgery are also difficult to determine. Neurovascular free-muscle transfer is now a standard procedure for the dynamic smile reconstruction of longstanding facial paralysis. This type of strategy has considerable potential in the treatment of facial paralysis in patients with hemifacial microsomia. We present here our experience with neurovascular free-muscle transfer for smile reconstruction in eight patients with facial paralysis associated with hemifacial microsomia. The age of the patients at the time of surgery ranged from 7 to 28 years old, (average, 13.9 years). Six were male patients and two were female patients. The two-stage method combining gracilis muscle transfer with cross-face nerve grafting was performed in three patients, whereas the one-stage transfer of the latissimus dorsi muscle was performed in five. To construct a natural or near-natural smile, the muscles were transferred into the paralyzed cheek in all except one patient, in whom the latissimus dorsi muscle was transferred into the sublabial area to reconstruct a paralyzed lower lip. A dermal flap segment vascularized with perforating vessels from the latissimus dorsi muscle was simultaneously inserted into the underdeveloped cheek for soft-tissue augmentation in this patient. Muscle contraction was evident in all patients between 4 and 8 months after muscle transfer. Our present series revealed that neurovascular free-muscle transfer is a good option not only for smile reconstruction but also for restoration of the facial contours of patients with hemifacial microsomia. Compared with the two-stage method combining gracilis muscle transfer with cross-face nerve grafting, the one-stage method using the latissimus dorsi muscle has some advantages, including a one-stage operation, a shorter recovery period, and the absence of sequelae that occur after harvesting a sural nerve. 相似文献

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. Compared with controls, HFS patients had significantly decreased ReHo values in left middle frontal gyrus (MFG), left medial cingulate cortex (MCC), left lingual gyrus, right superior temporal gyrus (STG) and right precuneus; and increased ReHo values in left precentral gyrus, anterior cingulate cortex (ACC), right brainstem, and right cerebellum. Furthermore, the mean ReHo value in brainstem showed a positive correlation with the spasm severity (r = 0.404, p = 0.027), and the mean ReHo value in MFG was inversely related with spasm severity in HFS group (r = -0.398, p = 0.028). This study reveals that HFS is associated with abnormal spontaneous brain activity in brain regions most involved in motor control and blinking movement. The disturbances of spontaneous brain activity reflected by ReHo measurements may provide insights into the neurological pathophysiology of HFS. 相似文献

The auditory brain-stem response (ABR) can detect anomalies both in the auditory pathways and in structures adjacent to these pathways. Patients with Duaneś retraction syndrome, associated with hypoplasia of the abducens nerve in the brain-stem, and patients with hemifacial spasm, due to compression of the facial nerve in the brain-stem, have been found to have abnormal ABRs. Marcus Gunn ptosis with ‘jaw winking’ is considered to be due to misconnection of oculomotor, trigeminal and other cranial nerves. Suspecting that perhaps some ‘jaw-winking’ phenomena may be due to detectable brain-stem anomalies we tested 7 patients with Marcus Gunn ptosis. Three of the patients demonstrated abnormal ABRs indicative of pontine pathology. 相似文献

Injury to the frontal or other facial nerve branches can result in an asymmetry that can be very distressful to both patient and surgeon. This is especially true following cosmetic procedures such as rhytidectomy. We propose a means to create temporary symmetry while awaiting the possible return of nerve function. Botulinum neurotoxin causes a muscle paralysis lasting for approximately 3 months, and it is well established as the preferred treatment for blepharospasm. A case is presented in which botulinum toxin type A was injected into the opposite functioning frontalis muscle of a patient with unilateral frontal nerve paralysis. The patient experienced satisfactory relief of the asymmetry caused by onesided forehead wrinkling and brow elevation. Botulinum toxin therapy should be considered for both temporary and permanent facial asymmetries due to facial nerve paralysis as well as spasm. 相似文献

Botulinum toxin type A creates temporary localised flaccid paralysis after injection into skeletal muscle. Thirty four patients with blepharospasm, of whom 28 also had the oromandibular dystonia syndrome, were treated with injections of botulinum toxin type A into the orbicularis oculi, and 28 showed functional improvement after the treatment. A high incidence of local side effects occurred, especially partial ptosis, which was well tolerated. There were no systemic side effects. The average period of relief was 2.5 months, increasing to 2.8 months after a second injection. Functional improvement was limited in patients with severe associated dystonia. 相似文献

Three hundred and sixty-five patients were given tetracaine intravenously for various types of pain and neuromuscular tension. In the treatment of pain, myositis, muscle spasm, and visceral spasm most patients were relieved. Best results were obtained in syndromes in which pain was associated with muscle spasm, such as in pain in the lower part of the back and scalenus anticus syndromes. The effects of tetracaine intravenously are those of analgesia, vasodilatation, and relaxation of spastic muscle. Sixty-five of the patients were treated for neuromuscular tension, and there was good relaxation and increased comfort. Alcoholics were relieved of some of the tension symptoms and may have been helped to resist the desire to drink. Of 14 patients with premenstrual tension, 13 had complete relief. Eight patients with mixed anxiety and tension states also responded well. Toxic and allergic reactions were negligible, and other side effects were infrequent and of no consequence. 相似文献

ABSTRACT: BACKGROUND: Surgical microvascular decompression (MVD) is the curative treatment for hemifacial spasm (HFS). Monitoring MVD by recording the lateral spread response (LSR) intraoperatively can predict a successful clinical outcome. However, the rate of the LSR varies between trials, and the reason for this variation is unclear. The aim of our trial is to evaluate the rate of the LSR after intubation following treatment with succinylcholine, vecuronium, or no muscle relaxant.Methods and designThis trial is a prospective randomised controlled trial of 96 patients with HFS (ASA status I or II) undergoing MVD under general anaesthesia. Patients are randomised to receive succinylcholine, vecuronium, or no muscle relaxant before intubation. Intraoperative LSR will be recorded until dural opening. The primary outcome of this study is the rate of the LSR, and the secondary outcomes are post-intubation pharyngolaryngeal symptoms, the rate of difficult intubations, the rate of adverse haemodynamic events and the relationship between the measurement of LSR or not, and clinical success rates at 30 days after surgery. DISCUSSION: This study aims to evaluate the impact of muscle relaxants on the rate of the LSR, and the study may provide evidence supporting the use of muscle relaxants before intubation in patients with HFS undergoing MVD surgery.Trials registrationhttp://www.chictr.org/ ChiCTR-TRC-11001504 Date of registration: 24 June, 2011.The date the first patient was randomised: 30 September, 2011. 相似文献

The benign essential blepharospasm is a subliminal form of primary torsion dystonia with still uncertain aetiology. It is characterized by involuntary convulsive muscle contractions of the M. orbicularis occuli, accompanied by unbearable pain of the cornea, eye bulb and the muscle itself. It has been suggested that blepharospasm is neurobiologically based on a dysfunction of the basal ganglia and an impairment of the dopamine neurotransmitter system. Therefore, therapy of blepharospasm contains administration of anticholinergic- and tranquillizing drugs as well as botulinum toxin as neuromuscular blocking agent. However serious side effects can be observed as well as failure of therapy. In the brain a dense co-localisation of cannabinoid (CB1) and dopamine (D2)-receptor was identified which had been associated with the influence of cannabinoids on the dopaminergic reward system. Additionally, it has been demonstrated that cannabinoids may have an impact on the central GABAergic and glutaminergic transmitter system and thus might be involved in the influence of movement control. In the present case we administered the cannabinoid receptor agonist Dronabinol (Delta-9-Tetrahydrocannabinol) to a woman suffering from severe blepharospasm. Multiple treatments with botulinum toxin did not reveal a long-lasting beneficial effect. By contrast, treatment with 25 mg Dronabinol for several weeks improved the patients' social life and attenuated pain perception remarkably. This case study demonstrates that the therapy with a cannabinoid agonist may provide a novel tool in the treatment of blepharospasm and maybe of other multifactorial related movement disorders. 相似文献
