摘　　要：To the Editor:Hemimasticatory spasm(HMS)is a relatively rare type of unilateral trigeminal nerve(TN)motor branch dysfunction,whose pathogenesis is currently unknown.The clinical manifestations of HMS are involuntary paroxysmal convulsions of the muscles innervated by the associated unilateral trigeminal motor branch.Recently,the academic community has proposed two etiologies for HMS:TN compression and central lesion theory.[1]Clinically,HMS must be distinguished from oromandibular dystonia,facial muscle spasm,multiple sclerosis pain spasm,and focal epilepsy.Generally,electromyography(EMG)can confirm the diagnosis.The current outcomes of multidrug and botulinum toxin injection treatments remain unsatisfactory.Only patients with cranial neurovascular conflicts have an excellent response to microvascular decompression(MVD)surgery.
