Efficacy of High-Dose Corticosteroid Therapy in Acute Stage Severe Facial Palsy in Children

ObjectivesTo evaluate the efficacy of high-dose corticosteroid for severe acute facial paralysis in children.MethodsThe present study enrolled 10 pediatric patients with House-Brackmann (H-B) Grade VI facial paralysis who received prednisolone (PSL) 3 to 4 mg/kg/d for 2 to 3 days followed by a 10-day taper (the child high-dose group). Eight pediatric patients who received PSL 0.5 to 1 mg/kg/d were enrolled in a child low-dose group, and nine adult patients (25-64 yr) who received a high-dose PSL 200 mg equivalent for 2 to 3 days followed by a 10-day taper were enrolled in an adult high-dose group. On the initial and follow-up visits, facial movements were evaluated using the H-B grading system. The degree of oral-ocular synkinesis was evaluated by the degree of asymmetry in eye-opening width during mouth movements. The synkinesis index was defined as a percentage of the interpalpebral space width ([normal side - affected side]/normal side).ResultsThe child high-dose group achieved a significantly better H-B score than the child low-dose group (p < 0.01). The synkinesis index was significantly lower in the child high-dose group than in the child low-dose group or the adult high-dose group (p < 0.05).ConclusionChildren receiving PSL 3 to 4 mg/kg/d achieved better recovery and less synkinesis than those treated with low-dose PSL (0.5-1 mg/kg/d).
