Auditory neuroma is a kind of disease with high incidence in people’s life nowadays, and many friends are not unfamiliar with this disease. However, there are still a lot of friends who have limited knowledge about acoustic neuroma, and they are not able to find the disease in time, and miss the best time for treatment. Experts pointed out that people should know more about the symptoms of acoustic neuroma, which is very helpful for the prevention and treatment of the disease. Then what are the symptoms of acoustic neuroma? Experts introduced that, the common symptoms of acoustic neuroma are as follows: 1. Early stage of acoustic neuroma When the diameter of acoustic neuroma is <2.5cm, it is the early stage of acoustic neuroma. Due to the compression of the cochlear and vestibular branches of the auditory nerve by the tumor in the inner auditory canal, the early stage of the tumor is characterized by symptoms of cochlear and vestibular dysfunction such as slow onset of tinnitus, hearing loss, vertigo, and gait instability, etc. However, sudden deafness can also be seen (accounting for about 10%). The frequency and severity of these common early symptoms vary from person to person, ranging from unnoticeable in mild cases to recurring episodes of vertigo or persistent unsteady gait that can interfere with daily life. Less common early symptoms include itching or tingling in the ear, numbness of the posterior wall of the external auditory canal, and decreased tearing on the affected side, which are caused by compression of the median nerve in the internal auditory canal. Symptoms of vestibular dysfunction, but also sudden deafness (about 10%). The frequency and severity of these common early symptoms vary from person to person, from unnoticeable in mild cases, to recurrent vertigo or persistent gait instability that can affect daily life in severe cases. Less common early symptoms include itching or tingling in the ear, numbness of the posterior wall of the external auditory canal, and decreased tearing on the affected side, which are caused by the compression of the intermediate nerve in the internal auditory canal. 2. Middle and late stage acoustic neuroma: The symptoms will be aggravated with the increasing size of the tumor. When the tumor extends to the bridge cerebellar angle, it can involve the trigeminal nerve, resulting in abnormal sensation and numbness of the affected side, dull or lost corneal reflexes, etc. If the tumor blocks the cerebrospinal fluid circulation, it can cause hydrocephalus and severe intracranial hypertension; if the tumor compresses the cerebellum, it can result in cerebellar dysfunction, such as fine motor disorders of the hands and feet of the affected side, and unstable gait; and if the tumor compresses the brainstem, it can result in weakening of limb strength, numbness of limbs, and decreased sensation. Tumor compression of the brainstem can lead to weakening of limb strength, numbness of limbs, hyperalgesia, etc. When the tumor grows to a certain extent, the intracranial pressure can be increased, resulting in headache, nausea, vomiting and other symptoms. Patients may suffer from sudden brain herniation. Symptoms of vestibular dysfunction, but also sudden deafness (about 10%). The frequency and severity of these common early symptoms vary from person to person, ranging from unnoticeable to recurrent episodes of vertigo or persistent unsteady gait that can interfere with daily life. Less common early symptoms include itching or tingling in the ear, numbness of the posterior wall of the external auditory canal, and decreased tearing on the affected side, which are caused by compression of the median nerve in the internal auditory canal.
