Abstract: Objective To explore the effect of Botulinum toxin-A (BTX-A) injected into the contralateral facial muscle on central facial palsy post stroke. Methods 30 stroke patients with moderate to severe central facial palsy were recruited (course of 3~10 months). They were divided into control group (n=15) and treatment group (n=15), who accepted facial training and BTX-A injection in addition, respectively.The bilateral deference of distance from angulus oris to the midline of the teeth(D1) and from the paropia to the angulus oris (D2) were measured before and 4 weeks after injection. Results The D1 and D2 both at resting and movement all decreased after injection in the treatment group, and decreased more than those in the control group. Conclusion BTX-A injection can further correct central facial palsy post stroke.
