Auditory neuroma is a benign tumor that occurs in the internal auditory canal and pontocerebellar horn. Early symptoms often manifest as unilateral tinnitus or hearing loss, which generally progresses progressively, and in some patients can manifest as sudden hearing loss. Performance: Early manifestation is unilateral tinnitus or hearing loss, which gradually worsens, and in a few cases, it can manifest as sudden hearing loss. As the tumor gradually increases in size, other symptoms of nerve involvement can appear, such as facial twitching or facial paralysis, facial numbness, etc. In later stages, if the tumor is too large, it may compress the brainstem, cerebellum and other important brain structures. If the tumor has the above mentioned manifestations, enhanced MRI is recommended. A normal ear or cranial CT cannot clearly show the tumor; if for some reason enhanced MRI cannot be performed, enhanced CT is recommended. Other evaluation of audiology is also required. Treatment: Currently, depending on the size and symptoms of the auditory neuroma, the following measures can be taken: close observation and follow-up, gamma knife irradiation therapy, and surgical resection.
