Hemifacial spasm is a painless neurological condition characterized by persistent or brief involuntary contractions of the muscles innervated by the facial nerve. Vascular compression triggers the primary hemifacial spasm, and secondary hemifacial spasm comprises all other causes of facial nerve damage.
According to the study published in The Scientific World Journal in 2014, it is found that hemifacial spasm is prevalent in 9.8 per 100,000 individuals, and the average age for the onset of hemifacial spasm is 44 years. It is also reported that women and Asian populations have a high susceptibility to hemifacial spasm.
It is noted that increasing technological advancements and growing awareness are the key factors driving the hemifacial spasm market. Nowadays, people are becoming more aware of different types of neurological disorders. Government and other different organizations have started educating people about hygiene and diseases through seminars, and conferences. Thus, increasing awareness has provided a push to the growth of the market.
Various other factors such as increased incidence of craniofacial tremor, and facial chorea, unmet medical needs, increasing government assistance, improving regulatory framework, increasing adoption rate, and rising funding and reimbursement are continuously contributing to the growth of the global hemifacial spasm market.
