Most auditory neuromas occur unilaterally. Although it develops slowly, it is adjacent to the brainstem and brain nerves. As the tumor grows larger, it will lead to tinnitus, hearing loss and eventually loss of hearing; further growth of the tumor will also cause symptoms of other cranial nerve invasion, such as facial nerve involvement and facial palsy, trigeminal nerve involvement and facial, tongue numbness, linguopharyngeal and vagus nerve involvement and cough weakness and swallowing difficulty. After the tumor compresses the cerebellum, it will cause unstable walking, vertigo and inability to complete some fine movements. Further development of tumor may cause hydrocephalus. Once the intracranial pressure increases, it will lead to aggravated headache, vomiting, vision loss and even brain herniation, which will threaten patients’ life. The current ideal treatment goal is total resection of the tumor and preservation of facial and auditory nerve function. The earlier the auditory neuroma is detected and the earlier the surgical treatment is performed, the higher the rate of preserving the function of facial and auditory nerves.
