There is no such thing as a small acoustic neuroma for which surgery is not recommended. Surgery to completely remove the tumor is the treatment of choice for this disease, which will continue to grow if left untreated. Acoustic neuroma is a benign tumor that occurs in the bridge cerebellar angle, and management includes microsurgical total excision, stereotactic radiation therapy, and follow-up observation. If left untreated, the tumor will continue to grow, causing symptoms of increased intracranial pressure such as headache, dizziness, nausea, vomiting, and in severe cases, ataxia, deafness, facial numbness, and even life-threatening. Surgery is the preferred treatment for acoustic neuroma, which should be selected according to the comprehensive selection of factors such as acoustic neuroma growth site and size, and most of them adopt suboccipital approach. If there are surgical remnants or the size is less than 3 centimeters, gamma knife treatment can be considered. If you have symptoms such as headache and discomfort, or if you are diagnosed with acoustic neuroma after examination, you should consult the doctor in time and follow the doctor’s instructions for treatment.
