Surgery for acoustic neuroma usually takes about 3 to 5 hours. It is recommended to analyze each case and go to regular hospitals for scientific and reasonable treatment. The most important treatment for auditory neuroma is generally surgery, which is best performed under electrophysiological monitoring conditions to protect the adjacent nerve function as much as possible. Factors such as tumor stage, location, size, patient’s physical condition and improvement of quality of life in the later stage will affect the progress of neurosurgeon’s surgical process and extend or shorten the operation time accordingly. Acoustic neuroma is a nerve sheath membrane tumor originated from Schwann cells of vestibular branch or cochlear branch of the auditory nerve, which gradually compresses the neighboring nerves during its growth, causing tinnitus, deafness, vertigo, and even convulsions, facial paralysis, and even compression of the cerebellum and brainstem, which is life-threatening. Because of the deep location of the acoustic neuroma and the complexity of the surrounding important nerve structures, the general operation time is about 3-5 hours. If the tumor is large and the adhesion is tight, the time may be prolonged accordingly.
