1.What is an auditory neuroma? Auditory neuroma is a benign tumor that originates from the balance nerve. 2.Is the incidence of auditory neuroma high? Auditory neuroma accounts for about 8% to 10% of intracranial tumors, and the incidence rate of the population is about 1 per 100,000. 3.What are the symptoms of auditory neuroma? The main symptoms of auditory neuroma are: hearing loss (95%), tinnitus (70%) and ataxia (65%). 4.What should I do if I find an auditory neuroma? Since auditory neuroma is a benign tumor, and with the development of neurosurgical instruments and equipment, as well as the advancement of microsurgical techniques, microsurgical treatment is the first choice. For smaller auditory neuromas, if there are concerns about surgery, observation for a period of time is sometimes an option. However, it is important to clarify that the growth rate of auditory neuromas is unpredictable, with tumors shrinking in 6% of patients without any treatment. However, the growth rate of some tumors can reach 2 cm/year, and the typical growth rate is 1 to 2 mm/year. 5.Is the surgery of auditory neuroma risky? The location of the auditory neuroma is in the CPA area (pontocerebellar triangle), surrounded by important nerve structures such as brain stem, trigeminal nerve, posterior group of cranial nerves, basilar artery, vertebral artery, etc. Therefore, the surgery is still risky. Of course, the risk of each patient varies. Generally, the larger the tumor is, the more difficult it is.
