Acoustic neurinoma, also known as neurilemnoma (schwannoma), is one of the most common benign intracranial neoplasms, accounting for about 10% of intracranial tumors, and originates from the vestibular branch of the auditory nerve. Over the years, the medical profession has accumulated rich experience in the treatment of auditory neuroma and developed a variety of methods. The more common clinical treatment methods for auditory neuroma in the past are imaging follow-up, surgery and gamma knife treatment. Imaging follow-up is determined by the likelihood that the patient will require treatment within the expected time frame. The unfavorable factors of life expectancy (advanced age, poor physical condition) and favorable factors of tumor (small size, stability, slow growth) are indications for conservative treatment. It is indicated for patients >60 years old and in a position to receive regular MRI examinations, with semi-annual MRI examinations in the first year and annual MRI examinations thereafter. If the tumor grows significantly, immediate surgery is indicated. Surgical treatment Microsurgical resection is currently the preferred treatment method, mainly transmural pathway, transcranial middle fossa pathway, and posterior transethmoid sinus pathway. The decision should be based on the tumor size, preoperative hearing condition, patient’s age and general condition. Since the auditory neuroma is located in the posterior cranial recess in the pontocerebellar horn region, and the anatomical structure of this region is quite complex, besides the brainstem and cerebellum, there are numerous cranial nerves penetrating between them, including many important blood vessels, and their branches, surgical treatment of auditory neuroma is difficult and extremely risky. Gamma knife treatment adopts the geometric focusing method of gamma rays, and through precise stereotactic orientation, a certain dose of gamma rays is planned and concentrated on the pre-irradiated target, which irradiates the auditory neuroma tissue with multiple fields and angles, and implements conformal radiotherapy according to the different shapes and sizes of the tumor.
