Filter by:The goal of this clinical trial is to test the effects of DaxibotulinumtoxinA-Lanm (Daxxify) in patients with benign essential blepharospasms (BEB) and hemifacial spasms (HFS). The main questions to answer: 1. Is there clinically significant difference (measured by Jankovic Rating Scale (JRS) score from base to peak efficacy) for patients with BEB and HFS treated with Daxxify? 2. What percentage of patients achieve a clinical response? Participants historically treated with Botox for either BEB or HFS will be crossed over to Daxxify treatment in order to serve as their own control and examine the efficacy of Daxxify.
Our hypothesis is that botulinum toxin injections (with onabotulinum toxin, incobotulinum toxin, and abobotulinum toxin) given at 10-week or shorter intervals for the indication of treatment of muscle spasms associated with neurological disorders are associated with equal safety and effectiveness as those given at 12-week or longer intervals. We also hypothesize that for those patients who would prefer a shorter inter-injection interval, but for whom their insurance carrier has prevented this, have worse health-related quality of life compared to patients who receive injections at a 10-week or shorter interval. We aim to investigate this hypothesis by collecting demographic and injection data and patient survey responses.
Up to now, multiplanar reconstruction (MPR) has been widely used to detect the neurovascular compressions (NVC) on the patients with hemifacial spasm (HFS). However, due to lack of stereoscopic vision, this traditional method sometimes can not meet the requirement on identifying the details of NVC, especially when the aberrant vessels turn out to be veins not arteries. The three dimensional analytic techniques, such as curved planar reconstruction (CPR) and magnetic resonance virtual endoscopy (MRVE), may be helpful to improve the sensitivity and specificity on the demonstration of NVC with stereo and dynamic views, so as to assist the design of the surgical plan. Furthermore, the frequent finding of NVC on MRI studies of asymptomatic patients incited the creation of several strict criteria for the imaging diagnosis of NVC: the vessel must cross perpendicular to the long axis of the nerve, the nerve must be deviated or indented at the root entry zoon (REZ) by the vessel. Alternatively, morphological measurement of the nerve may correlate with the severity of facial spasm due to atrophy of the nerve in most cases of HFS, and is likely secondary to the micro-structural abnormalities, such as axonal loss, demyelination, collagen deposition, etc. In this study, cross-sectional area (CSA) and volume (V) of the cisternal facial nerve will be assessed to determine whether it can be a useful biomarker for predicting the degree of HFS.
To observe the prevention and treatment effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative dizziness in patients with hemifacial spasm undergoing microvascular decompression surgery, and its possible mechanisms.
A 50-Week Prospective, Double-Blinded, Randomized, Cross-over design in Multicenter Study of 100 unit of Abobotulinum Toxin Type A (Dysport®) versus 33.33 unit of Neubotulinum Toxin Type A (Neuronox®) Injection for Hemifacial Spasm in Thai Patients, designed gor comparing the effectiveness of Total intensity score after 4. 12. 16 and 24 weeks of treatment and to compare the long-term safety of the injections. Abobotulinum toxin A (Dysport *) dose 100 units compared ot neubotulinum toxin A injection (Neuronox / Neuronox®) dose 33.33 units. that it si non-inferiority (non-inferiority) ni the treatment of hemifacial spasm after administration of the drug ni the 0, 12" ,26", and 38" weeks ni the treatment of patients with hemi facial spasm, with a wash out period of 2 weeks between treatments. By proving the non-inferiority of Total intensity score at ,4 ,8 and12 week after treatment which calculated by severity score and duration of facial muscle spasm (hour per day)., as well as severity score and duration of functional impairment (hour per day) recorded for 4,8, and 21 weeks after each treatment between 33.33 unit of Neubotulinum Toxin Type A(Neuronox*) and 100 unit of Abobotulinum Toxin Type A (Dysport*)
- Review the clinical outcomes of Micro vascular decompression of Hemi facial Spasm. - Assess safety and efficacy of Micro vascular decompression. - Improve the outcome of these patients and decease rate of recurrence and complications.
A triple-masked placebo-controlled trial assessing the efficacy and safety of pretarsal versus preseptal botulinum toxin for patients with eyelid spasm. The investigators hypothesize injection of botulinum toxin into the pretarsal orbicularis oculi muscle will have greater clinical efficacy, better measured quality of life, fewer complications, and better cost effectiveness in comparison to a preseptal pattern of injection.
Twenty-four consecutive patients with Hemifacial spasm and 25 age and gender-matched randomly selected eyes of healthy volunteers underwent corneal pachymetry and intraocular pressure measurements using Goldmann Applanation Tonometer and non-contact tonometer. An interval of 15 minutes was maintained between Goldmann Applanation Tonometer and non-contact tonometer measurements. Intraocular pressure measurements were performed before (during hemifacial spasm) and 2 weeks after Botox injections in Hemifacial spasm patients and in healthy volunteers without Botox injections. All the measurements with Goldmann Applanation Tonometer were carried out by a single physician while those with the non-contact tonometer were done by another physician who was masked to the results of the Goldmann Applanation Tonometer. All measurements were taken between 10:00 and 11:00 a.m.
Hemifacial spasm patients who received botulinum toxin A injection were divided into two groups. Group A received unilateral injection while group B received bilateral injection. Patients completed follow-up A researcher record facial videos and analyzed facial symmetry and completed 3 scales.
