Auditory neuroma, also known as auditory nerve sheath meningioma because it originates from the nerve membrane, is a common benign tumor in the cerebellar pontine angle, most common in middle-aged people aged 30-50 years old, and there are more females than males. Due to tinnitus, deafness, and dizziness in the early stage of the disease, the disease is mostly diagnosed in the otolaryngology department at the beginning of the diagnostic period. When the tumor gradually increases in the inner ear canal, it will push or compress the auditory nerve, vestibular nerve and the accompanying internal auditory artery, which in turn will affect the blood supply of the inner ear, and as a result of the degeneration of sensory structures, it will manifest as unilateral slow progressive (occasionally sudden) deafness, high-pitched tinnitus, dizziness, and a feeling of instability, and the tumor may also directly destroy the bone labyrinth and produce similar symptoms. If the median nerve and facial nerve are pushed down, there will be pain in the ear, changes in secretion of salivary and lacrimal glands, abnormal taste sensation in front of the tongue, hemifacial spasm, muscle weakness or paralysis. If the tumor develops towards the cerebellar pontine angle, it firstly destroys the tip of the rock and the trigeminal ganglion on it, which will cause numbness of the side of the affected person and the disappearance of corneal radiation. If the tumor is in contact with the brainstem and cerebellum and presses them, it can cause spontaneous nystagmus and ataxia. If the tumor is too big, it can cause peripheral venous reflux obstruction and cerebrospinal fluid circulation obstruction, which can cause the intracranial pressure to rise, and headache, nausea and vomiting can be seen. The diagnosis can be confirmed according to typical symptoms and examination results, and the difficulty lies in early diagnosis. Early resection is the only effective way after diagnosis. Tumors confined to the inner ear canal can be removed by cranial fossa, labyrinthine or post-labyrinthine approach, while large tumors or bilateral tumors that are compressed and adhered to the brainstem and cerebellum should be removed by suboccipital or joint approach under the operating microscope and under the close supervision of the facial nerve and the heart.
