Leong and Lesser (2015) reported that 880 members of the British Acoustic Neuroma Association were e-mailed a survey of which 480 were returned from people who had been diagnosed and treated for acoustic neuroma, and 465 had complete data, used for analysis. Acoustic neuroma treatment ranged from surgical excision for 47 percent of the respondents, stereotactic radiosurgery was the treatment for 25 percent, some 23 percent had serial MRIs, and the remaining 5 percent had surgery and stereotactic radiosurgery.
