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\*)
