Auditory neuroma must be diagnosed and treated as early as possible. Otherwise, there is a high risk of missing the best treatment period, which will directly lead to facial nerve damage, resulting in serious consequences such as facial paralysis and ear deafness. The treatment goal of auditory neuroma is to remove the pressure of tumor on brainstem and cerebellum, and to relieve the hydrocephalus caused by tumor pressure on brain ventricle. Therefore, once detected, surgical resection is the preferred treatment. In the past, the length of surgical incision for auditory neuroma was more than 10 cm, which was traumatic and unattractive. With the advancement of minimally invasive microscopic technology, we use the posterior inferior occipital mastoid approach, where the incision is completely within the hair traces and the length is only 5 cm, and the bone window is located at the intersection of the transverse sinus and sigmoid sinus, which requires less than 3 cm in diameter. In the past, it was often necessary to remove part of the cerebellum or forcibly extract the cerebellum to enter the operative area to reveal the tumor, which would inevitably cause serious damage to the cerebellum. Modern minimally invasive technique is to release the cerebrospinal fluid by opening the occipital pool, reduce the tension of the posterior cranial fossa, and enter the operation area through the natural gap of the cerebellar rim after the cerebellum collapses, which can remove the tumor without damaging the cerebellum. In the past, most of the surgeries were performed by biting off the skull, which did not have serious consequences, but the brain tissue lacked the protection of the skull from then on. Modern minimally invasive techniques use bone plate reduction or titanium mesh repair to restore the normal anatomical structure of the skull. And with intraoperative electrophysiological monitoring, it is not difficult to completely resect the tumor and complete the anatomical protection of the facial nerve. Hearing preservation during auditory neuroma surgery has become a new goal to be pursued in modern minimally invasive neurosurgery. However, not all procedures for auditory neuroma can achieve these goals. Hearing preservation in patients with auditory neuroma is directly related to tumor size and preoperative hearing level. In patients with tumor diameter <2 cm and preoperative functional hearing, the higher the preservation rate of facial nerve and auditory function after surgery. Therefore, early diagnosis and treatment are crucial to improve the preservation rate of facial and auditory nerve function after auditory neuroma surgery. For small tumors that cannot tolerate surgery, gamma knife treatment can be given. There are strict surgical indications for the selection of gamma knife treatment for auditory neuroma, and only tumors of a certain size can be selected for gamma knife treatment. Specialists in clinical treatment also found that some patients have to undergo surgery again precisely because of unsatisfactory gamma knife treatment, and such patients because of previous experience with gamma knife treatment will also affect the outcome of the surgery.
