				        	Hemimasticatory muscle spasm (HMS) is a rare disorder of masticatory muscle caused by abnormal motor branch of trigeminal nerve; it is similar to hemifacial muscle spasm in symptoms, but it is even rarer. So far, only dozens of cases have been reported internationally. At present, the etiology of HMS is not completely clear, among which demyelinating lesions caused by compression of the trigeminal nerve motor branch by deep tissues or blood vessels are generally accepted by scholars. Research progresses on the etiology, clinical manifestations, diagnosis, differential diagnosis, and treatment plans of HMS are reported as follows, in order to provide ideas for clinicians to better identify and treat the disease.
