Hemifacial spasm in childhood.
A nine-year-old girl presented with right hemifacial spasm (HFS) of 27 months duration. Stimulation of the right supraorbital nerve produced synkinesis of the ipsilateral facial muscles. Latency and amplitude of the blink reflex were equal bilaterally. Other investigations including computerized tomography (CT) were negative. Treatment with carbamazepine was not helpful. This is the third reported case of HFS in childhood.
