Below are the dangers of acoustic neuroma introduced by experts. 1.Hearing impairment: patients often report tinnitus, sense of obstruction in the external ear canal, hearing loss, especially poor sense of high pitch, this kind of deafness is called neurodeafness or sensorineural deafness. This deafness is called nerve deafness or sensorineural deafness. The performance of tuning fork test air conduction is stronger than bone conduction, i.e., Rinne (Rinne)’s test is positive; bone conduction and the normal side (or the examiner), the duration of the sound is short for Schwabach (Schwabach)’s test is positive; Weber (Weber)’s test, the sound is biased towards the healthy side. 2, balance disorders: patients feel dizzy, nausea and vomiting, pale and sweaty vagus nerve stimulation symptoms. Examination can be found nystagmus, positive indication test, that is, the patient’s two upper limbs to the front of the horizontal straightening, closed eyes on the sick side of the limb to the affected side of the skewed, tilted, in the closed-eye difficult to stand test is more significant; stepping test is abnormal, that is, with eyes closed, in a straight line forward, backward 5 steps, repeated, the patient is deflected to the side of the patient, the trajectory of a star, also known as the star trajectory gait.
