Normal muscle mitochondrial function in Ramsay-Hunt syndrome

Mitochondrial encephalomyopathies may display clinical features similar to Ramsay-Hunt syndrome (RHS). We studied muscles mitochondrial function in 2 patients with RHS. Histochemical and ultrastructural studies of muscle biopsies and biochemical analysis of muscle mitochondrial enzymes were normal. There is no evidence for a disturbance of muscle mitochondrial function in RHS.
