==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 the ages of 30 and 60.<ref>{{Cite web | title =NIH Acoustic neuroma Incidence| url =http://www.nidcd.nih.gov/health/hearing/pages/acoustic_neuroma.aspx }}</ref>
The [[incidence]] of acoustic neuroma ranges from 0.3 to 1 per 100, 000 individuals. The [[prevalence]] of acoustic neuroma is approximately 0.2 per 100,000 individuals. Women are more commonly affected by acoustic neuroma than men. Most cases of acoustic neuroma develop in individuals between 30 and 60 years of age.
==Epidemiology and Demographic==
 
Acoustic neuroma account for 7-8% of all primary intracranial tumours 2 and 75-90% of cerebellopontine angle masses 1-2,8. Bilateral vestibular schwannomas are highly suggestive of neurofibromatosis type 2 (NF2), although bilateral tumours are encountered in the familial form of acoustic schwannomas in the absence of other stigmata of NF2.<ref>{{Cite web | title =Radiopedia Acoustic neuroma Epidemiology| url =http://radiopaedia.org/articles/acoustic-schwannoma }}</ref>

Overview

The incidence of acoustic neuroma ranges from 0.3 to 1 per 100, 000 individuals. The prevalence of acoustic neuroma is approximately 0.2 per 100,000 individuals. Women are more commonly affected by acoustic neuroma than men. Most cases of acoustic neuroma develop in individuals between 30 and 60 years of age.

Epidemiology and Demographics

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.[1][2][3]

Incidence

The incidence of acoustic neuroma ranges from 0.3 to 1 per 100, 000 individuals.[4][5][6][7]

Prevalence

The prevalence of acoustic neuroma is approximately 0.2 per 100,000 individuals.[8]

Mortality rate

The in-hospital mortality rate of surgery for acoustic neuroma in the United States is 0.5%.[9]

Age

  • Most cases of acoustic neuroma develop in individuals between the ages of 30 and 60.
  • Although quite rare, they can also develop in children.[10]

Gender

Acoustic neuroma can affect women more often than men.[11]
