Meige syndrome, also known as idiopathic blepharospasm-oral and mandibular dystonia syndrome, was first reported by French neurologist Henry Meige in 1910 and is a rare dystonic disorder that affects middle-aged and elderly people aged 40-70 years, with more women than men. Some patients may have trunk tremor. Meige syndrome is classified into three types based on clinical manifestations: (1) blepharospasm; (2) blepharospasm combined with oromandibular dystonia; and (3) oromandibular dystonia.
