Overview
The incidence of acoustic neuroma is approximately 1 per 100,000 individuals worldwide. The prevalence of acoustic neuroma is approximately 2,500 new cases per 100,000 individuals. Women are more commonly affected with acoustic neuroma than men. Most cases of acoustic neuroma develop in individuals between 30 and 60 years of age.[1]
Epidemiology and Demographic
Acoustic neuroma accounts for 7-8% of all primary intracranial tumors and 75-90% of cerebellopontine angle masses. Bilateral vestibular schwannomas are highly suggestive of neurofibromatosis type 2 (NF2), although bilateral tumors are encountered in the familial form of acoustic schwannomas in the absence of other stigmata of NF2.[2]

Prevalence
Acoustic neuromas are estimated to affect approximately 1 in 100,000 people in the general population.
Incidence
Approximately 2,500 new cases are diagnosed each year.
Gender
Acoustic neuromas affect women more often than men, but it is not significant.
Age
Most cases of acoustic neuroma develop in individuals between the ages of 30 and 60. Although quite rare, they can develop in children.
