Abstract
Hemifacial spasm (HFS) represents a challenging cranial movement disorder primarily affecting the facial nerve innervated muscles, with significant prevalence among Asians. Botulinum toxin type A (BoNT/A) injections, established as a primary therapeutic intervention since FDA approval, offer considerable effectiveness in alleviating spasms, albeit accompanied by challenges such as temporary effects and potential adverse events including facial asymmetry. This comprehensive review underscores the crucial need for harmonising neurological benefits and aesthetic outcomes in HFS management. The discussion delves into the interplay between facial aesthetics and neurological objectives in BoNT/A injections, emphasising precise techniques, dosages, and site considerations. Distinct aspects in neurological and aesthetic domains are also examined, including detailing the targeted muscles and injection methodologies for optimal therapeutic and aesthetic results. Importantly, evidence regarding various BoNT/A formulations, recommendations, and reconstitution guidelines in both neurology and aesthetics contexts are provided, along with a schematic approach outlining the stepwise process for BoNT/A injection in HFS treatment, addressing critical areas such as orbicularis oculi muscle sites, eyebrow correction strategies, mid- and lower-face considerations, contralateral injection sites, and post-injection follow-up and complication management. By highlighting the culmination of neurological efficacy and facial esthetics in BoNT/A treatment for HFS patients, this review proposes a holistic paradigm to achieve balanced symptomatic relief and natural aesthetic expression, ultimately enhancing quality of life for individuals grappling with HFS.

Abstract
OBJECTIVE This study aimed at assessing mental health in patients with hemifacial spasm (HFS) and determined the effect of botulinum toxin type A (BTX-A) on psychological distress in patients with HFS. METHODS Ninety-five HFS patients and 95 age- and sex-matched healthy controls were enrolled. Symptom checklist-90 (SCL-90) scores were used to measure psychological distress in HFS patients and healthy controls. The mental health status of HFS patients was also evaluated by SCL-90, before and after the injection of BTX-A. Moreover, for those patients with abnormal mental health, efficacy outcomes after treatment with BTX-A were compared with a propensity score-matched historical cohort without BTX-A treatment. RESULTS The mean scores for interpersonal sensitivity, phobia, anxiety, depression, and somatization were significantly higher among HFS patients than healthy people (P < 0.05). There was no significant difference between female patients and male patients in HFS group (P > 0.05). There were significant improvements in somatization, interpersonal sensitivity, depression, anxiety, and phobia scores before and after treatment (P < 0.05). At 2 months, more patients experienced an improvement in psychological distress in the BTX-A group (61.29% versus 38.71%; P = 0.03). CONCLUSION Patients with HFS are often accompanied by somatization, interpersonal sensitivity, depression, anxiety, and phobia. Our findings suggest that BTX-A can improve these symptoms. However, further well-designed prospective studies are warranted to validate our findings.

Abstract
BACKGROUND Many rehabilitative attempts have been made to prevent or reduce residual deficits in patients with established and long-term facial palsy (FP). In many clinical settings in-situ injection of collagen-based medical devices have been demonstrated to provide nutritional support for tissues. AIM To test the effectiveness of a collagen-based treatment for patients complaining of long standing FP, who are following a proprioceptive neuromuscular facilitation protocol (Kabat method) (group A), compared to a FP group only undergoing the Kabat method (group B). DESIGN Randomised controlled trial. SETTING Tertiary referral outpatient center and University Hospital. POPULATION Forty-one patients with a medical diagnosis of long-term unilateral peripheral FP. METHODS Twenty-one Group A patients were compared, after randomization, to nineteen matched group B patients after 8 weeks of treatment. The outcomes were electromyographic findings, validated questionnaires (Facial Disability Index, FDI and General health-related quality of life assessment, QOL) and clinical grading (House-Brackmann, HB, and synkinesis grading scale). A correlation analysis was performed between pre-/post-treatment differences (Δ) in outcome and clinical-demographic measures. RESULTS A significant within-subjects improvement, both in electrophysiological and questionnaire scores, was found in both groups. When compared with group B, group A patients exhibited a significant reduction of post-treatment polyphasic potentials of voluntary activity of orbicularis oculi (P=0.017) and oris (P=0.015) and a significant increase in post-treatment duration of voluntary activity of orbicularis oris (P=0.018). Group A subjects demonstrated a significant improvement in questionnaire subscales regarding overall disease perception. Although positive correlations between the ∆FDI and ∆percentage of polyphasic potentials of voluntary activity were found in both groups, negative correlations in group A were found between disease duration and ∆duration of voluntary activity of orbicularis oculi and oris. CONCLUSIONS The combination of physical rehabilitative procedures with in-situ collagen injections, possibly acting in redirecting the phenomena of reinnervation/reorganization, demonstrated encouraging results in patients affected by long term FP. CLNICAL REHABILITATION IMPACT In-situ collagen injection could be a safe option enlarging the 'window of opportunity' to improve the voluntary muscle contraction pattern and general and specific disability referred by patients affected by long standing FP.

Abstract
BACKGROUND Hemifacial spasm (HFS) is a debilitating disorder characterized by intermittent involuntary movement of muscles innervated by the facial nerve. HFS is caused by neurovascular compression along the facial nerve root exit zone and can be treated by microvascular decompression (MVD). The goal was to determine rates and predictors of spasm freedom after MVD for HFS. METHODS A literature search using the key terms "microvascular decompression" and "hemifacial spasm" was performed. The primary outcome variable was spasm freedom at last follow-up. Analysis was completed to evaluate for variables associated with spasm-free outcome. RESULTS A total of 39 studies including 6249 patients were analyzed. Overall spasm freedom rate was 90.5% (5652/6249) at a follow-up of 1.25 ± 0.04 years. There was no significant relationship between spasm freedom versus persistent spasm and age at surgery, timing of follow-up, gender, disease duration, side of disease, or vessel type. Spasm freedom was more likely after an initial surgery versus a redo MVD (odds ratio 4.16, 95% confidence interval 1.99-8.68; P < 0.01). CONCLUSIONS MVD works well for HFS with cure rates >90% at 1-year follow-up in 6249 patients from 39 studies. A significant predictor of long-term spasm freedom at 1 year was an initial MVD as compared to repeat MVD. The majority of published manuscripts on MVD for HFS are heterogeneous single-institutional retrospective studies. As such, a large-scale meta-analysis reporting outcome rates and evaluating significant predictors of spasm freedom provides utility in the absence of randomized controlled studies.

Abstract
The objective of this study was to demonstrate the efficacy of intramuscular botulinum toxin type A (BTX-A) as a method of controlling the symptoms of focal facial dystonia. A prospective, longitudinal, observational, pre-post (case-series) single-centre study was conducted over a period of 3 months, involving 30 patients with focal dystonia. The patients were enrolled on a first-come, first-served basis. For all patients, the abnormal movements were evaluated using the Abnormal Involuntary Movement Scale (AIMS). The AIMS results were recorded immediately before BTX-A injection (primary predictor variable) and after 3 months (the toxin reaches its maximum effect 2 weeks after injection, and the effect is maintained for 3 months). An improvement in AIMS score was the primary outcome variable. Treatment efficacy was evaluated using the Pearson correlation index with a level of significance of P<0.05. The average age of the study subjects was 70.9±12.7years (20 female, 10 male). The mean dose of BTX-A used was 27.4±20.5U. The mean improvement in AIMS score after treatment was 5.2±4.2. A significant correlation was found between the dose applied and the reduction in AIMS score (P<0.05). BTX-A can be used in the treatment of focal dystonia and provides reproducible results.

Abstract
Hemifacial spasm is characterised by unilateral contractions of the facial muscles. Though considered to be benign by many people, it can lead to functional blindness and a poor quality of life due to social embarrassment for the suffering individual. Botulinum toxin therapy is an excellent noninvasive tool to treat this condition. However, surgical decompression of the aberrant vessel is also an upcoming approach to therapy for this condition.

Abstract
Botulinum toxin type-A is currently thought to be effective and safe for hemifacial spasm (HFS). The pre-synaptic block of acetylcholine release at the neuromuscular junction induces depression of orbicularis oculi muscle compound motor action potential (CMAP). The aim of our study was to evaluate at what extent end-plate functional recovery is possible even in botulinum toxin treatments lasting up to 15 years. We examined 81 outpatients with primary HFS (mean treatment duration = 7.2 ± 4.2 years) who underwent neurophysiologic study, once clinical effect of the previous treatment had vanished. The mean CMAP amplitude, mean rectified amplitude of response 1 (R1) of the blink reflex and area of response 2 (R2) of treated orbicularis oculi muscle were measured in comparison to the controlateral side. Mean amplitude of the above mentioned parameters was slightly lower (about 20%; p < 0.001) in the treated side at the end of the follow-up period (4.7 ± 1.7 months). The CMAP amplitude reduction weakly correlated with the interval from last treatment, while other neurophysiologic parameters did not change due to treatment duration or total toxin amount. Our study demonstrates that botulinum toxin affects compound motor action potential and blink-reflex responses for at least 4-5 months in HFS patients. The residual block is slight and does not increase with repeated injections after several years of treatment. Our study, beside confirming the long-term efficacy of botulinum toxin treatment for HFS, provides neurophysiologic evidence that therapeutic effect may be obtained without hindering the regenerative potential of the nerve-muscle complex.

Abstract
Hemifacial spasm is characterized by intermittent tonic or clonic contractions of the muscles supplied by the facial nerve. Although vision is less impaired than in patients with blepharospasm, the disease can impose significant psychosocial burden on patient's life. Botulinum toxin (BoNT) is the well-established pharmacotherapy of choice, but evidence from controlled clinical trials is sparse. There is a broad variety of rating scales used in clinical studies with BoNT and obviously no consensus has been reached how to assess treatment outcome in hemifacial spasm. Clinical rating scales focusing on objective function were used in a couple of controlled studies with BoNT and were appropriate to discriminate between BoNTA and placebo. But it has not been shown that they would be sensitive enough to detect minor differences between several BoNT formulations. Although most of the clinical scales consist of a five-point rating, the descriptors for the ordinal numbers are not necessarily the same so that the results of different clinical studies are not comparable to each other. The main disadvantage of clinical scales is that they do not take into account patient's perspective of disability and impact on daily life. For this reason some clinical studies applied health-related quality of life (HRQoL) questionnaires to assess efficacy, and one research group worked on the development of disease-specific tools. Although these HRQoL questionnaires have been validated and a good correlation to disease severity could be demonstrated, they are far from having become an established variable for efficacy assessment in hemifacial spasm trials. The challenge remains to establish tools which are appropriate to rate BoNT treatment effects in hemifacial spasm. Currently, it is virtually impossible to identify one rating scale which can cover all relevant aspects of the disorder. In consequence we recommend the implementation of a combination of different rating scales which address functional impairment as well as those issues which are most important to patients. Further research is needed to standardize and validate rating scales for hemifacial spasm in clinical studies.

Abstract
CONCLUSION Rehabilitation was significantly efficient in both groups of patients with synkinesis, especially in those in whom treatment with botulinum toxin type A (BTX-A) preceded physical rehabilitation. OBJECTIVE To determine the influence of preventive treatment with BTX-A on synkinesis when physical rehabilitation is planned. METHODS Twenty patients, who recovered from facial palsy with final House-Brackmann (HB) grade II and III, were randomized to assess the efficacy of preventive BTX-A treatment on final synkinesis score after physical rehabilitation. Synkinesis was graded according to the four-point scale derived from the SunnyBrook Facial Grading System (FGS). Physical rehabilitation was carried out using NeuroMuscular Retraining Therapy (NMRT). In the randomized groups, NMRT was administered with (group a) or without pre-BTX-A treatment (group b). RESULTS Patients who were preliminarily treated with BTX-A in the affected area showed a 2.1 improvement of score on the SunnyBrook scale (p < 0.001), with significantly better results in comparison to the non-BTX-A group.

Abstract
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.

Abstract
BACKGROUND AND PURPOSE To review the clinical characteristics and the long-term outcome of patients with hemifacial spasm (HFS) who received botulinum neurotoxin (BoNT) over the past 10 years. RESULTS A total of 108 patients received 665 treatments. Mean latency of clinical effect was 5.4 +/- 5.3 days for Botox and 4.9 +/- 4.6 days for Dysport (P > 0.05). Mean duration of clinical improvement was higher after the injection of Dysport than Botox: 105.9 +/- 54.2 and 85.4 +/- 41.6 days respectively (P < 0.01). The percentage of treatment failures was 6.5% for Botox and 4.6% for Dysport (P > 0.05). The doses of Botox significantly increased over time (beta = 0.35, P < 0. 001) whilst Dysport dose remained unchanged (beta = 0.16, n.s.). The duration of clinical benefit slightly increased with Botox (beta = 0.12; P < 0.01), but remained constant for Dysport. Side effects occurred in 17.4% of treatments: 16.7% of patients who had received Botox, and in 19.7% who had received Dysport (P > 0.05). The most common side effects were palpebral ptosis and lacrimation; ptosis and lagophtalmos was more common in Dysport treatments (P < 0.005). CONCLUSIONS Both brands are effective and safe in treating HFS; efficacy is long-lasting. The differences in outcome and side effects confirm that, albeit the active drug is the same, Botox and Dysport should be considered as two different drugs.

Abstract
BACKGROUND The therapeutic uses of botulinum toxin have been expanding due to deeper knowledge of its molecular behaviour and different mechanisms of action. OBJECTIVE To present suggested doses of Botox and Dysport for controlling the muscle hyperkinetic activity in facial palsy in the perioral area and to review other uses. METHODS An extensive updated literature review on the success and limits of the botulinum neurotoxin (BoNT) therapeutic treatments. RESULTS/CONCLUSION BoNT can be considered to be the preferred single method for many disorders; it has substituted for some conventional surgical methods and it can be associated with other therapies to increase overall treatment performance. Depending on the disorder, the lack of permanent effect causes no major inconvenience.

Abstract
Although neurosarcoidosis seems to occur in only 5% to 10% of patients who have sarcoidosis, it may lead to significant complications. The diagnosis of neurosarcoidosis usually relies on indirect information from imaging and spinal fluid examination. Although MR imaging remains the most sensitive technique for detecting neurologic disease, other tests, including positron emission tomography scanning and cerebral spinal fluid examination, can provide important information. The role of immunosuppressive agents such as methotrexate, cyclophosphamide, and azathioprine has been expanded, and these agents should be considered for the treatment of some manifestations of neurosarcoidosis. Reports of the antitumor necrosis factor agent infliximab suggest that this drug can be helpful for patients who have neurosarcoidosis.

Kubat WD, Rekant M. Botulinum toxin use as an adjunctive modality in a patient with multiple flexor tendon ruptures. Hand (N Y) 2008; 3:237-9. [PMID: 18780102 PMCID: PMC2525885 DOI: 10.1007/s11552-008-9091-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2007] [Accepted: 02/22/2008] [Indexed: 10/22/2022]
Abstract
Botulinum toxin A has been described in treatment protocols for several disease processes, from primary axillary hyperhydorosis to esophageal dysfunction. It is best known for its use in plastic and dermatological practices. Botulinum toxin has a straightforward mechanism of action. The toxin inhibits acetylcholine release at the neuromuscular junction causing a chemical denervation, which ceases contractions of the muscle. With its minimal side effect profile, botulinum toxin should be considered when muscle spasm is a detriment. This case involves an injury to the hand of a patient with a history of intermittent diffuse muscle spasms. Subsequently, due to the patient's previous upper extremity muscle spasms, repeated flexor tendon repair ruptures of the index finger occurred until botulinum toxin was administered to the offending muscle. The patient has not required any additional surgical interventions for the repaired tendon and is now actively flexing all digits. This case report demonstrates how botulinum toxin can be used in a clinical scenario when decreased muscle activity is desired to promote tendon healing.

J Clin Neurosci 2008; 15:253-6.

Abstract
This study was performed to investigate the differences in response to botulinum toxin treatment between patients with idiopathic versus neurovascular hemifacial spasm. A total of 69 patients with hemifacial spasm were investigated prospectively with cranial magnetic resonance imaging and magnetic resonance angiography. Neurovascular contact was found in 23 patients. All patients were assessed with a severity scale and a disease awareness scale. After treatment, the patients with idiopathic hemifacial spasm improved significantly in terms of both severity and awareness scores, but the patients with neurovascular hemifacial spasm improved only in the awareness scores. In conclusion, patients with idiopathic hemifacial spasm experienced a greater improvement after treatment with botulinum toxin than did patients with neurovascular hemifacial spasm.

Abstract
This article reviews the current and most neurologic uses of botulinum neurotoxin type A (BoNT-A), beginning with relevant historical data, neurochemical mechanism at the neuromuscular junction. Current commercial preparations of BoNT-A are reviewed, as are immunologic issues relating to secondary failure of BoNT-A therapy. Clinical uses are summarized with an emphasis on controlled clinical trials (as appropriate), including facial movement disorders, focal neck and limb dystonias, spasticity, hypersecretory syndromes, and pain.
