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. A total of 40 patients, 31 patients with HFS and 9 patients with BEB, participated in this study. Each patient received both PS and PT BoNT-A injections in a crossover design study. Latency to response, duration of improvement, the Jankovic Rating Scale (JRS), self-response scale, patient satisfaction scale, and complications were compared. Low-dose injections of BoNT-A at the PT portion produced a significantly higher response rate in terms of latency to response, duration of improvement, JRS, self-response scale, and patient satisfaction scale than the PS injections. Major side effects including ptosis and droopy eyelid were observed only after the PS injections. These findings confirmed that low-dose injections of BoNT-A at the PT portion provide more efficacy, patient satisfaction, and fewer complications than the PS injections for the treatment of involuntary eyelid twitching and closure in patients with HFS and BEB.  相似文献

Hemifacial spasm (HFS) is a chronic movement disorder which presents as clonic and/or tonic facial muscle contractions frequently accompanied by many other sensory (visual or auditory disturbances, pain), motor (facial weakness, trismus, bruxism, dysarthria) and/or autonomic (lacrimation, salivation) symptoms. The aim of the study was to assess the occurrence of HFS non-motor and motor-related symptoms and their responsiveness to botulinum toxin type A (BTX-A) therapy. 56 HFS patients were included in the open-label design study. Patients were examined three times: before BTX-A injection, and 2 and 12 weeks later. The occurrence of non-motor and motor-related symptoms was assessed by a special questionnaire, and the severity of HFS was rated by the Clinical Global Impression-Severity scale (CGI-S) and depression symptoms by the Beck Depression Inventory (BDI). Over 81% of the patients before BTX-A therapy reported HFS non-motor and motor-related symptoms. Almost 50% of the patients reported more than three symptoms. The most frequent symptoms were: tearing (44.5%), eye irritation (39.3%), facial paraesthesia (26.8%) and hearing of a “clicking” sound (25.0%). 2 weeks after BTX-A injection 75% of the patients did not report any symptoms and 20% reported only one or two. 3 months later the number of symptoms had increased again, with 57% of patients reporting at least one. The number of HFS non-motor and other symptoms did not correlate with the patients’ age, disease duration and the presence of neuro-vascular conflict, but were positively correlated with the CGI-S and BDI scores. This study showed that muscle contractions in HFS patients are commonly accompanied by non-motor and other motor-related symptoms and most of them are reduced following BTX-A treatment.  相似文献

Abstract

Botulinum toxin type A (BTX) injection into the orbicularis oculi muscle is an effective treatment for patients with hemifacial spasm (HFS). The objectives of this study were to investigate the effect of this treatment on HFS, in particular the associated hyperexcitability of the facial motor nucleus, and to discuss the potential mechanism of HFS. F waves in the mentalis muscle were examined before, 2 and 6 weeks after the BTX treatment of only the orbicularis oculi muscle in ten patients with HFS. F/M ratio, duration of F waves and frequency of F waves decreased significantly after the BTX treatment compared with those before the BTX treatment. These findings demonstrate that the excitability of the facial motonucleus decreases after BTX treatment of the orbicularis oculi muscle. From these results, we hypothesize that the trigeminal afferent input and the cortical control contribute to the hyperexcitability of the facial motor nucleus in patients with HFS. This warrants further investigation into the pathophysiology of HFS.  相似文献

Background and purposeHemifacial spasm (HFS) is frequently accompanied by other symptoms, such as visual and auditory disturbances or pain. The aim of the study was to assess the occurrence of auditory symptoms accompanying HFS using subjective and objective methods, their relation with other HFS symptoms, and their resolution after botulinum toxin (BTX-A) treatment.Material and methodsThe occurrence of hypoacusis, ear clicks and tinnitus was assessed by questionnaire in 126 HFS patients from an electronic database which included medical data such as severity of HFS rated by clinical scale and magnetic resonance imaging focused on the presence of vascular nerve VII and VIII conflict. Forty consecutive patients treated with BTX-A and 24 controls matched by sex and age underwent laryngological examination including audiometry, tympanometry and acoustic middle ear reflex before injection and two weeks later.ResultsAbout 45.2% of patients complained of auditory disturbances (31.7% hypoacusis, 30.2% ear clicks and 7.1% tinnitus) on the side of HFS. Auditory disturbances correlated with severity of HFS symptoms but not with age, disease duration, or neurovascular conflict with nerves VII and VIII. We did not find abnormalities in audiometric and tympanometric assessment in patients in comparison with controls. No abnormalities were detected in brainstem evoked potentials comparing the sides with and without HFS symptoms. Tinnitus and absence of ipsilateral acoustic middle ear reflex occurred more often in patients with auditory symptoms than those without them. BTX-A treatment caused resolution of subjective acoustic symptoms without any improvement in audiometric assessment.ConclusionsAuditory disturbances accompanying HFS are probably caused by dysfunction of the Eustachian tube, which improves after BTX-A treatment.  相似文献

Although the beneficial effect of subcutaneous injections of botulinum toxin type A (BTX-A) is well known in both blepharospasm and hemifacial spasm, the position of the injection sites around the orbicularis oculi may influence the effectiveness and side effects. Here we report results of preseptal and pretarsal BTX-A injections in 53 patients (25 blepharospasm and 28 hemifacial spasm) in whom we used both injection techniques successively. Pretarsal injections were used in 102 out of 186 treatments in blepharospasm group and in 84 out of 202 treatments in hemifacial spasm group. Pretarsal BTX-A treatment produced significantly higher response rate and longer duration of maximum response in both patient groups. This technique was also associated with a lower frequency of major side effects such as ptosis. We concluded that injections of BTX-A into the pretarsal, rather than the preseptal portion of the orbicularis oculi is more effective for treatment of involuntary eyelid closure due to contractions of this muscle.

We retrospectively evaluated 118 patients with cervical dystonia (CD) treated with botulinum toxin type A (BTX-A) for the following variables: gender, age at evaluation, age at symptom onset, disease duration, presence of head/neck pain and/or tremor, pattern of head deviation, disease progression (spreading of symptoms), etiology (primary vs. secondary), pretreatment with oral medication, and Tsui score. We investigated whether these parameters could predict the clinical outcome in a short- (<30 days) and long-term basis. On short-term treatment, there were no clinically significant differences between BTX-A responsive and non-responsive patients. On long-term treatment, however, intake of oral medication previously to BTX-A injection and higher Tsui scores were predictors of favorable response. These results suggest that the greater CD severity the more likely patients will respond to BTX-A.  相似文献

Background and purposeHemifacial spasm (HFS), a movement disorder manifested by unilateral spasms of the muscles innervated by the facial nerve, interferes with social life in about 90% of patients, causing social isolation and depression and having a significant impact on the quality of life. The aim of the study was to assess factors affecting the quality of life in patients with HFS in respect of influence of the severity of depression symptoms and botulinum toxin type A (BTX-A) therapy.Material and methodsEighty-five out of 129 patients included in the HFS database of the Movement Disorders Out-patient Clinic, Department of Neurology, University Hospital, Cracow who fulfilled the inclusion criteria and had no exclusion criteria (suffering from concomitant movement disorders, other severe chronic diseases or cognitive impairment) were studied. Demographic and clinical data (age at onset, disease duration and accompanying symptoms) were collected. Severity of HFS was assessed by the five-point clinical scale and seven-point Clinical Global Impression scale. Quality of life was assessed with the HFS-36 questionnaire and severity of depressive symptoms was evaluated with the Beck Depression Inventory. HFS-36 was performed twice, before BTX-A injection and two weeks later.ResultsThe mean global score of HFS-36 was 47 ± 31 (maximum: 140 pts). Decreased HFS-36 score resulted from divergent deterioration in all subscales included in the questionnaire. Independent risk factors of deterioration in HFS-36 were increased severity of HFS and depressive symptoms as well as accompanying trismus. The HFS-36 score depended on the number and type of accompanying symptoms as well. Botulinum toxin type A therapy led to a significant improvement of HFS-36, particularly high in patients with multiple (> 4) HFS-related symptoms.ConclusionsThe HFS-36 score depends mostly on severity of HFS, depressive symptoms and occurrence of accompanying trismus. It improves after BTX-A treatment.  相似文献

Twenty seven patients with hemifacial spasm (HFS) and sixteen patients with blepharospasm (BS) having mean Jankovic disability rating scale score of 2.56+0.58 SD and 2.81+0.54 SD, respectively, were treated with botulinum toxin A (BTX-A) injections. The total number of injection sessions were ninety one with relief response in 98.91%. The mean improvement in function scale score was 3.78+0.64 SD and 3.29+1.07 SD respectively, in HFS and BS groups. The clinical benefit induced by botulinum toxin lasted for a mean of 4.46+3.11 SD (range 2 to 13) months in HFS group and 2.66+1.37 SD (range 1 to 6) months, in BS groups. Transient ptosis was seen in 4.39% of total ninety one injection sessions. These findings show that local botulinum toxin treatment provides effective, safe and long lasting relief of spasms.  相似文献
